Greetings beetle gurus
My father in law is the original owner of this 2000 green diesel automatic bug. These are the only codes that are showing. 250k on the odometer.
Codes again are p0715. P1556. And p0380
Again thanks in advance for your insights.
First, what exactly is going on with the car? You give codes, which is great, but it would also be helpful to know the symptoms of the car as well.
The P1556 code looks to be a boost issue. I'd check and make sure all hoses are connected, and if they are, its probably a bad N75 valve. The p0380 code is for the glow plugs, so either a plug is bad or there is an issue with the glow plug wiring harness (which is a very common problem). The p0715 code is for the speed sensor.
Thanks for the quick reply!
We are in the northern part of Wisconsin and it is colder than...... here. So it is a difficult starting issue and a lot of blue smoke on startup. I'm guessing that is a lot of unburnt fuel. Although he states th at it does use more than the usual amount of motor oil.
He also says th at it doesn't shift to top gear either. Th at one is a mystery to me. He has put seafoam through it and says that it works better for a while
He'll be dropping it off at my house for a few weeks and I would like to get this thing back up to speed for him. Or tell him it's a basket case.
Oh yea 65 mph isn't achievable at this time.
Another problem (in addition to problems shown by the trouble codes); that seems to be common on high milage TDIs, is the clogging up of the manifold, there are videos on youtube showing how people do it with a propane torch or other ways. They really get clogged up; maybe his is, thus such poor acceleration. His maybe fine but if it has never been done before; it seems like it could possibly be clogged up, worth a look anyway!
