Title: TDI Wonder 4.0
Post by: mr.mindless on July 31, 2022, 09:16:25 PM
$700 2000 auto sedan in silver, lighter grey cloth interior in ok shape. 150k-ish
Some rocker rust, bad passenger fender (came with replacement)
Supposedly good automatic
Fresh tires on 15s
Recent reman injection pump
Quit and won’t start. Timing belt is whole, tight, and has teeth on it. Hoping it’s just a couple teeth out of time. Lifters are not shattered and are against the cam, so I may have underpaid, not overpaid. I’ll find out soon!

I was shopping for a boat donor. This might be a flip instead? TBD as yet.

It’s a stripper model. Manual windows and mirrors.

Lots of parts and a FULL set of timing belt service tools in the trunk.

3.5 cans of starting fluid, 2 gallons of new oil, and a zip tie on the glow plug harness

Paperwork found says injection pump may be bad replacement. Will start from scratch and see.

injection pump locked up, will rotate 1/3 turn or so before a hard stop in both directions, with fuel lines off. timing belt is mostly stripped of teeth. The crank still turned the cam though. Engine would do a full revolution, so valves might be OK.

Polish pump rebuild ebay'd, timing belt kit ordered.
timing belt had a loose and bent bolt on the big idler pulley too. That wouldn’t have lasted.

Will probably pull camshaft for ease of getting crank to TDC without interference. Might pull injectors or GPs and make sure all holes hold air pressure. I don't remember if I have the right fittings to do a compression test on these.

Bottom of car looks pretty OK. Some rocker issues that look no worse from bottom than from top, and disconnected exhaust. Front end of that looks like it was never sealed up on the bottom at the cat, and the top of the weld is fine. back near that clamp it has a bunch of goobers and is fully separated.

Polish injection pump arrived today. Haven’t been in the shop since I pulled this apart. Hopefully it just goes together and runs.
Title: Re: TDI Wonder 4.0
Post by: mr.mindless on August 14, 2022, 11:12:39 PM
This is really fighting me. All went together great. No setup mistakes on the belt, everything went together just dandy. Double checked my work a couple times now.

Pop tested the injectors and they looked decent after some cleaner went through them and tested even pressures too. All 4 glow plugs tested good on a battery too.

Have sucked clean fuel through the new injection pump and gotten all air out.  No computer indicated issues.

But the damn thing doesn’t want to fire. Injectors didn’t want to seal perfectly to the head. Third try on that and I broke a hold down bolt. Got that out of the head and found a replacement in my metric bolt bucket, still no dice.

I didn’t get to do a compression test. I do have a right size adaptor for the glow plug hole, but it only cleared everything in #1. Hits injector or head casting on other holes. Maybe I’ll have to figure out a right setup for that and confirm no piston-kissed/ bent valves that are killing compression.

appears that this was an extremely stubborn bleed for some reason.

I got frustrated enough with it that I threw starting fluid at it and it fired. There were a few cans of starting fluid in the trunk, so I'm not going to think I did anything worse to it than what the previous owner already did...
I loosened injection lines at the injectors and got lots of foam.

I fired it a couple times on ether with the lines loose, tightened them up, and it fired and runs. restarted without issue after shutdown. Hopefully it'll cold start too.

Time for coolant and accessory belt and intake and to GTFO the lift.
Does have a fuel leak at #4 injector, not sure where but did dry off to check, and that is now wet.

Trans seems good. 4.5 mile test drive down and back on Whalen
Need to do a little tuning to fix a rough idle and find a fuel leak that showed during test drive and chase the initial blinking brake light problem and make sure that’s not catastrophic before I put Sarah’s plates on it for until we find her something permanent.
I suspect the blinking brake light is just ebrake actuation switch but I’ll find out Monday or Tuesday…

Now i can finally get my wagon in for altErnst it and new injectors (hard start hopeful solution, it’s about all that’s left.

First time I’ve ever driven a TDI automatic. 0-30 or so is great. 40-60, put away the stopwatch and get out a calendar. Lol

Started several times today. No further issues. Had a code set for weak key signal.

I’m very very very impressed with this headlight restore. Did it on my z4, great for months there so far. Brought these lights back from almost entirely opaque.

(https://uploads.tapatalk-cdn.com/20220912/04cd039d71223579946ad0c4103fc715.jpg)

Committing to this as the stop gap car. Sarah replacing the equinox on her insurance tomorrow and I’m writing up the paperwork to title to her and put her plates on it.

Has a BRAKE and ABS light on, reports rear wheel speed sensor issues only. Bearings feel great. I don’t expect a BRAKE light blinking from that, just abs. Strange.

Exhaust repair and it’ll be good to go until whatever happens next. I’ll drive it for a few days first. While I wait for radiators

Needed: ~18” of 55mm/ 2.25 exhaust tubing

Looks like my stock is all 3” and 5”

I am surprised I didn’t save exhaust tubing from the last VWs I scrapped but I seems I didn’t :(

I forgot to try putting clear over the Krylon silver to see if it matches the car better.

IWas gonna say it’s not a lot better than a black fender would be if I just bolted the new one on. But on second look in different equally poor lighting it’s not toooooo bad

The clear made it look way worse. Splotchy. Either a mismatch or the clear is shot. It wasn't under-shaken...


Put almost 50 miles on so far today. check engine popped on, didn't pull code yet. ABS light stays all the time, the blinking BRAKE light was gone once but then back the next key cycle. Only brake codes previously were both rear wheel speed sensors. At a glance they looked good and the wires looked good but I didn't do a full trace.

Has a pretty good exhaust smell, I think the flex pipe must be cracked, and that's up by the engine so pretty annoying. As in "I hope the turbo studs don't all break off when I pull the exhaust" annoying.

Rear abs sensors swapped. Pain in the ass, they are crazy tight in the hole. Had to drill out one previously broken hold down bolt.

And light still lit, blinking brake light gone. Didn’t check if cruise is fixed - probably not, with abs light still lit.

Didn’t get to the radiator on my wagon with all the mower trouble. Tomorrow night hopefully. Get the wagon ready for car camping at F&F

Getting down to nit picky stuff.

Still have to do that RF ball joint
Door sensors are screwed up (drive door always closed and doesn’t power lock, but will unlock)
Check and see if there’s any hope of AC
Headliner is sagged out
There was a cooling fan in the giant box of parts.
Swap in cup holder center console
Swap broken glove box
Shampoo seats

I had sprayed that replacement fender with silver Krylon. It orange peeled horribly. I gave it some 400 grit, and was going to wipe it down with brake cleaner to clean up for another coat, and all the paint came off the black primer that it shipped with!

Ditto haha

I tried to fix my headliner twice with headliner glue. The second time I removed it. It seems to just pull another layer of whatever the deteriorating material that the headliner is made out of. I ended up just screwing some long strips of thin flexible plastic stuff up there that I had laying around.

Post by: mr.mindless on September 19, 2022, 03:05:03 PM
I tried to glue the wagon headliner once, same result. I don't think it lasted a week. Once that foam starts to degrade it's all over. No sunroof in this one to help hold it up, either. It's off my head though so aside from seeing it flap in the back window in the rearview I could forget about it.

I have a bookmark about replacing a microswitch in the door latches to fix that but have never bothered. I have 2 or 3 in the wagon that are wrong too. Haven't checked the red Golf. I don't know how big a deal it is to R&R the latches. I also don't know if the switch that monitors latch open/closed is related to the door lock actuator, or if the lock actuator has somehow become a one-way motor.

Did yall replace the headliner fabric itself? or tried to glue back up the old factory headliner?     

When I replaced my Mazda6 headliner, this was the process:  https://www.facebook.com/media/set/?set=a.1214921907202&type=3

TLDR, took down entire headliner out of vehicle.  Scrubbed off the old foam down to the bare headliner board/backing (I used stiff brush).  Sprayed on glue and put on new headliner fabric. 

It worked for a couple years after that in FL summers then I got rid of it.

I did the same in my Eagle, Matt. Stayed up for a couple years.

I was thinking about it on my way in this morning and was wondering how to get the headliner out of the car. rear hatch makes it pretty easy. I don't know how the trim around the sunroof is done but I don't have to worry about that on this one. May just pull the fabric off so it's not flapping in the breeze. I haven't done that before.
Title: Re: TDI Wonder 4.0
Post by: mr.mindless on September 19, 2022, 06:09:58 PM
ABS light went out after one additional key cycle past repair. Still no cruise. Hopefully I can find the switches in bag com and see if the cruise on/off is dead.

Possible the switch was added or a turn signal stalk with switches was swapped if for switch failure and isn’t connected, or Ecu isn’t coded for cruise. It is a BASE model.

Did that lower ball joint. Smooth as butter until a stainless caliper pin stripped in the cast knuckle on reassembly.

That stainless pin got hogged out to 5/16 ID spacer, and it’s through bolted with a gr8 and a stainless nut that I gave some thread damage to for locking. Hopefully that’s a permanent fix.

Found that damn hvac bulb out. Ordered like 4. Hopefully I don’t lose them before I need more. I don’t really have a bulb home. Guess I need one.

“Vented” when filling this for the first time this morning and it leaked some fuel. So not going to gut that to make a bigger fuel tank. Reasonably sure nothing leaked when fuel shut off naturally.

Calling it done for now. HVAC bulb and drink holder center console swap sometime.

Tweaked IP timing when i got home. Sarah couldn’t start it yesterday, showed too retarded on the graph. Perfect now, will see how it starts when it’s fully cold off again.

Need to replace a PCV hose, will have an intake leak right now, that’ll be here tomorrowish. HVAC bulbs are here.
Title: Re: TDI Wonder 4.0
Post by: mr.mindless on September 26, 2022, 10:15:08 AM
Crap start this morning. Some fuel at the lines on the IP after cleaning all last night to leak check. Hopefully that’s all it is. A few other adjustments to try too before pulling things apart to double check accuracy of timing marks plus accurate setting thereof.

Bah. Glad it’s not salting season quite yet

Title: Re: TDI Wonder 4.0
Post by: mr.mindless on November 10, 2022, 10:08:04 PM
This leaked fuel the very first time I filled it, when I vented.

Sarah lost the top 1/8 tank way too fast and it left a puddle last night.

No obvious source. I removed the lines and the fuel sender. Fuel all over the top of the tank there. Gasket in good shape, sender and retaining nut in good shape. All plastic.

Hoping the r&r fixed it. May do a low pressure test once it’s below half a tank. Running great and starting reasonably otherwise.
Title: Re: TDI Wonder 4.0
Post by: mr.mindless on November 13, 2022, 05:58:30 PM
Door switch fixed. I think this one may get a new latch sometime. Have to put pressure on the plug to make good contact. Complex assembly to look for loose pins inside it. No stock on the shelf at the moment.

Nice to have remote lock work along with cabin lights and the key and light buzzers
Title: Re: TDI Wonder 4.0
Post by: etk300ex on November 14, 2022, 09:26:35 AM

Yup. I have micro switches in stock to replace.

It’s an impressive amount of labor to strip the door and not fuck anything up. I have it down to a science now after doing 3 doors, 5 times. Lol

Fuel leak found and fixed. waiting for RTV to set before I re test and put the tank back up.

mouse nest between the body and the fuel tank, mouse chewed through one of two fuel vent lines that run from the top of the tank to the fuel filler neck. No way to get the tank all the way out without dropping the beam. Just enough clearance to work above the tank with shocks pulled and tire removed and tank tipped towards the rear. Patched the plastic line with 1/4" fuel injection line, brass nipples, and adhesive shrink tube to up-size the 1/4 barbs to the plastic line. coated the outside of the adhesive shrink with black RTV and hose clamps. It's a vent line, so no pressure, but I'll see if it deals OK with intermittent diesel contact every time the tank is filled full 🤞🏻

Otherwise I'll have to get a factory replacement line and cut the stainless steel keepers at the filler neck and at the tank.

Confirmed intital glance yesterday: not radiator.

Found bad routing on lower rad hose that had it almost worn through against another clamp, and when I shifted that I got a drip out of the thermostat housing at the block. No new o rings in stock. Ordered a thermostat kit; some extra o rings for stock; and a new lower hose.

Stranded in the garage at home right now. Couldn’t force it to be ok. Shame on me.

Post by: mr.mindless on February 05, 2023, 11:38:32 PM
Got that immo issue taken care of late Monday night. What a fuck of a day that was… now if it doesn’t read the cluster will blink but it will run.

Just did the lower rad hose, stat neck and gasket, and the biggest leak I think was the spider o ring at the driver side of the head above the trans.

Radiator doesn’t look great and I probably should have spent the extra couple hours to change it, but I still haven’t seen a drip from it and all those that have leaked have looked much worse with big crusty separation at the tanks. This thing looks like it’s had tap water in it at some point so a CLR flush is probably called for when I do swap radiator.

20 year old cars do need attention now and then I guess.

Hopefully the shop mice drink up what I left on the floor…

Snows off. Right front wheel bearing changed. Found a pretty good method on changing the bearing. MUCH better than the first time i did one when i was still in the trailer on my very first vw. No pics.

A one piece double ball bearing is pressed into the knuckle and retained with a big c clip. then the hub flange & spline is pressed into the bearing. Can beat the hub out from the back side pretty easily, then suck the bearing into the 4” pipe with washer and sockets and a long bolt. Installation simply the reverse of removal haha
 
Hopefully it’s quiet now, the right front bearing was loose but it sounded like left side bearing from both sides. I’ve been wrong by ear every time in these cars so only test drive will tell. It had a good amount of play for 150k miles.

Damage limited to hood fender and light. Put a spare light in it, straightened hood and fender enough to clear light. The hood is kinked in a couple spots, to repair it, I’d need to split the skin from supports. So existing fender and hood are going to ride for a bit. There’s a cheap golf on marketplace with a good silver frontend on it, hope to hear back from him and get a car for the price of a hood.

I smelled some coolant a day ago when we drove this, found upper radiator hose swollen like a ballon and weeping. Didn’t have new on the shelf but had a used from another vw model that I trimmed to fit, so that and an overdue oil change and this is ready to go. Didn’t put the snows on it yet.

Has been starting hard. Will check timing next time it’s up to temp.

Battery gave up midday yesterday after like 4 good starts only a couple miles apart, then a 20 minute drive to work.

Jumped and made it home. No charge light. Didn’t look at it again yet.

I’m tired of cars.

Hard start comes and goes. Sometimes it’ll start instantly after sitting for days. Sometimes it’ll damn near kill the battery restarting at lunch time. Very strange.

I want to just add a lift pump to it as a bandaid.

Hard start intermittency getting worse.

Throwing a bandaid at it this weekend with an in-tank pump along with new fuel filter and thermo tee.

In tank fuel pump doesn’t seem to have helped much.

Engine oil and filter
Fuel filter and thermo tee
Rear brake pads

3.5 cans of starting fluid, 2 gallons of new oil, and a zip tie on the glow plug harness


did you check the zip tie?

Checking glow plugs and harness is on the Real Short List. More glow cycles help but I do wonder if not all 4 are lighting up. It’s a warm restart issue sometimes too, and ambient temp doesn’t fully correlate. I also need to check intake. It should still be clean, but need to verify that as well as that the shutdown flap isn’t sticking shut or something like that, choking it.

I’d forgotten about that zip tie, wherever it is.

Test drive after brakes failed so it’s back in the shop. May need rear calipers, which I remember being like $20 and they now are 75+

Hopefully I just need to work the ebrakes to get them to adjust and take up slack. Had to WORK to get them backed off but they freed up once they started moving but now rear brakes come on the second pump even after a few stops.

Manually closed up that caliper a bit and then the ebrake adjustment started working, maybe not as aggressively as intended but stops great now. All set

In Henrietta to pick this unit up right now. Hopefully it’s a failed starter and not something seized. Ran fine when shut down so hopefully I just get to teach Sarah how to change starters when they now fail every sixty days

used spare starter on the shelf that came with the car cranks and starts it, but is slow. Old starter comes out but doesn't even try to spin.
Bosch reman on the way from FCP Euro. New is backordered. Automatic trans is different from manual. So I guess I don't get to drive the caddy that I spent last week working on. Rustwagen for me I guess, with its new overboost issue instead of the old underboost problem.

Jeez.  I feel like mine is getting extra loud again.

Bosch reman starter in. Much, much, much quicker start, but runs real rough for a minute. I still need to check GPs & harness, and pull injectors and see if they're leaking down. I think fuel is more likely, a cold hole with healthy fuel would clean up much quicker if it were a glowplug thing.

Door switches failed again and driver door thinks its closed and locked at all times. No headlight buzzer or interior lights or means to disable the security system BECAUSE the remote also died. Related somehow? I don't know. The alarm triggers at hood open or ignition actuation and probably trunk or other door too. Someone didn't change a remote battery as suggested when range was decreasing and the remote isn't working at all right now with a new battery. I haven't gone through that one before. Also sprung an underhood fuel leak somewhere, IDK if it's low or high pressure side, probably low because it was running fine.

Excellent all around.

Someone is very fed up with this. Possibly understandably.

fuel leak was a return line plug having gotten spit out. concequence of adding a couple psi of positive fuel pressure. I wonder if any others will pop off now that a new plug is clamped in.

Reconnecting the battery with the key on disabled the alarm. remote refuses to work. Forgot my diagnostic laptop up in Rochester so going to probably ignore the rest of this until later so I can properly diag all the switches in the doors too, but at least it's drivable again..

Looks like the fuel leak ate a cooling system o ring? Or coincident failure. Looks like o ring 13 or pipe 11 is dribbling coolant. Hard to see for sure behind the injection pump, but I don’t think it’s parts 9 or 13 that got changed a few months ago.
