Was hoping to get it over for a sticker today. Damn catalyst has failed the last 3 or maybe 4 times I’ve tried to set readiness. Every single time since I replaced the downpipe over the last 2-3 weeks.
Secondary air injection has been the troublesome monitor since I got this car. I don’t know why since the fan runs and it’s output is connected. Must be a bum solenoid or something.
Now I’m stuck with
P0420 catalyst bank 1 efficiency below threshold
Grr

Wish the ground was drier to get under the car. I don’t remember if I managed to break that sensor loose when i was doing exhaust, I’m afraid i didn’t. That makes throwing an anti fouler or two on that o2 much tougher.
I looked through the easy stuff for SAI (secondary air injection) and it seems good at a glance. Next steps on trying to make that work would be to test the solenoid that lets air into the head in the exhaust chambers, and test the vacuum bits that drive it. They all click or run as applicable but vacuum could be missing there or the solenoid could be bad.
I don’t have a mighty vac to actuate the solenoid.
Wish I remembered where my service manual CD was, so I could dig out a CD drive and check full vac diagrams and diag procedures.
Lot of effort for a stupid sticker. Wasted 2-3 hours trying to get the cat monitor to set and it won’t. 100% fail rate. Even at cruise with way higher cat temps. min tempt to test is 440 C and that’s where it is in a lot test cycle. on the highway at 53mph is 600 +/-20. Driving that slow is annoying but max rpm to test is 2200.

Small price for another year if sticker I guess

Bad stretch here with a starter and a fuel pump and the catalytic code that makes me care about that valve.

Buddy at my last job is huge into VWs and always tells me to NEVER buy one haha

Electric blower runs on demand, blows into a passage in the head via a vacuum actuated solenoid that must open to allow air through. Vacuum controlled via computer controlled electronic solenoid.
I’ll be happy once it has a sticker and I can consider next steps on sending or driving.

Exhaust hit a speed bump today. I apparently fucked something up. Perhaps that’s cause if cat fail code even though I don’t sea a bad leak.
I think the buggy may have to spend a minute outside to get me outta the weather with the dumb cars.

Twice stopped and once sobriety checked for expired sticker tonight. No tickets. Blew .046 second time. Didn’t get out first time. That was a relief of magnitudes.
Somehow less stressful than any stops with the truck & trailer.

dropped.
totally a $2750 car now especially with snows and traction control!

probably sell the TDI for more. I think I'd be happy either way, but if the Jetta goes, Titan likes the Golf so selling the truck could then be on the table. I'm up in the air about that option. I love it and it could potentially be a forever rig - but with Joe, do I need it? If Joe breaks I do. But actively planning on that... IDK. Tough call.
