MMTR Allroad Idiocy

That's the best fix!

Picked up a little vibe ~45mph on the way home last night. Getting a bit worse on the way in today. Stopped to check for a loose wheel. Nothing noted in a parking lot where shake.

I’m thinking it could be a driveshaft or axle joint maybe. Present under accel, not under neutral or coast. Gotta get it up and look at it.
Due for oil change anyway.

Ordered lower arms and left axle shaft. Be here week from Tuesday. Slap that in along with the front air struts I think.

right front axle shaft seems to be my issue. boot is split, has a bit of click/play. Driveshaft is all good and rear axle shafts feel good.

The last 15 minutes of the 1:10 home from work today were fantastic.

Pulled in for gross coolant leak that showed up last time I went to drive it, which may have been to go to Jeff's party a month ago or so? Flat dead battery, it's 2 years old and has never had any issue at all.

Went through the underside closely and have a sorta long list. Bad CV boot, bad axle seal on rear diff, oil leak. Bah. Need to tip the nose out to 'service position' to dig into thermostat housing to see if it's an o-ring or a cracked plastic housing causing the leak.

If the plastic is knackered, I believe this is the correct metal replacement. noted for self

Impressed me today, and Sarah enjoyed. If there’s any action pics, they’re on her camera.

Moved around 4-5 times since Attica trip.
Left key on yesterday and batter went flat. Would not start. Charged and disconnected. Started once and then won’t restart.

Consistent codes:

2 Faults Found:
17800 - Camshaft Position Sensor Bank 2 (G163)
P1392 - 35-00 - Open Short to Plus

17745 - Camshaft Position Sensor (G40)
P1337 - 35-00 - Short to Ground

audi / VW so fun with dead batteries!

[mr.mindless]

bolts backed out, sensor broken. hell of a coincidence!

[mr.mindless]

found a ton of fuel all over the injectors from cranking. have new o-rings coming too.

I know I have EVAP issues, would be nice if I can nail that down and get the MIL off for a sticker someday.

[mr.mindless]

Injector o rings was a pretty easy job. Fuel rails are one unit with a bunch of extra claptrap piping. All fixed on those fuel leaks.

New sensor installed. Same codes. Really long crank time (didn’t count it off, has to be 2 seconds or more when it’s always been more like 3 revolutions) but it least it starts every time now.

Didn’t note any wiring damage but I guess I need to dig deeper

[mr.mindless]

Long crank to start and run. Guess it’s good enough-ish. Will disconnect sensors and see if codes change.

Water neck swap next week for fall color run. It’s dumping coolant again for fun. Confirmed source.

[mr.mindless]

Water neck swapped. Fully risky move to shortcut pulling alternator and bracket by pulling timing belt off of passenger camshaft. It was fine.

[mr.mindless]

Both cam sensors confirmed getting 4.97v at the plugs sure seems like that isn’t “shorted”

I suppose I should check resistance across the pins on the sensors

I don’t have a perfect means to backprobe or to scope the signal wire of the Hall effect sensors but these codes don’t seem to say no signal.

Hmm.
