Seeing if any interest here. I picked up this car off of a mechanic, non running condition. It had the broken timing belt wrecked head. I got a head in good condition and checked the piston protrusion in block for any issues. None were found, reassembled myself and timed the fuel pump perfectly...

Checking interest here, see craigslist posting https://houston.craigslist.org/cto/d/fayetteville-2002-volkswagen-beetle-tdi/6969374095.html Pasted from Craigslist: ~187k miles. I bought this manual transmission Beetle from a mechanic and it had broken timing belt. It has some cosmetic damage...

Interesting. Yea stage 4 is a lot more power! The engines are amazing have such a large margin for increased power output. I regard them as the best diesel engine Volkswagen ever made. Sent from my iPhone using Tapatalk Pro

I’m not sure how the MAF interacts with charge pressure but we will see. Rule it out! Sent from my iPhone using Tapatalk Pro

Not to ressurect an old thread but I'm trying to understand this also, troubleshooting an overboost condition on a 2002 bug tdi. When at idol, if it's supposed to be at max or stop screw, is that max boost or max no boost? Trying to understand the theory here. I'm going to replace MAF and...

I just found this..lol. This doesn't look hard at all maybe I can clean it all from there, I'm hoping https://www.youtube.com/watch?v=m7Us4wczZSE&app=desktop Thx!

Interesting. I’ll check that out. I guess that filter is not in play during recirc mode? Is that accessible under passenger area or where? Thx! Sent from my iPhone using Tapatalk Pro

I've been fixing up a car I got from a mechanic. It sat a while many months and apparently the intake air is clogged with a mouse nest somehow. Where exactly do the VW bugs get outside air in? Is there any way to easily clean this from outside the car short of tearing the dash apart? I already...

Not worth it car is old lol waiting to die Sent from my iPhone using Tapatalk Pro

My Jetta gasoline has 525 also but it’s on last legs with head gasket leak. It’s been running on blue devil sealant for 20k now ...amazing. But it overheats and stuff now as the sealant sludges the engine. Only overheats in summer and it doesn’t seem to hurt anything hahaha. Incredibly robust...

Friend had our old family commute car with 525k. It would have made it but they hit an elk. What a shame lol Sent from my iPhone using Tapatalk Pro

Who knows lol. As far as I know. Rarely seem to fail Sent from my iPhone using Tapatalk Pro

Used alh tdi injectors? I have some from an old engine head that I probably don’t need

Yea that’s a weird one then. Either loss of vacuum somehow or somehow heat causing vanes to stick or something odd. Have to rule things out. All vacuum lines are replaced? I did that to my old golf to be sure. Isn’t too hard. I just used simple regular rubber tubes. Sent from my iPhone using...

Well ya gotta also make sure the modulating valve works properly. I think some people swap them with another one on the car? I forget. Some people may know more it’s been a while. I think there may be some vag com checks for the valve but not sure. There is some sort of mode you can put it in...
