Hi guys!
I recently bought a 2006 Jetta TDI with the 1.9 BRM engine and the Borg Warner Turbo. I bought it as a basket case because these conditions were not letting the car go fast at all, or even just go.
Emissions Workshop Light was on
Codes were P0299, P0671, P0101
Looked at glow plugs and one was broken, physically broken, replaced that and engine still ran like crap
Smokey and acrid smell out of exhaust
I did my research and was almost convinced that the turbo smart actuator valve was shot, since a lot of people say this goes first and gives many if not all of the conditions above.
I am inherently lazy, before I pulled the turbo completely off, which turned out to be difficult I checked to see if the valve held vacuum. It holds vacuum fine!!!!! Onto other things....
I found that the hose that attaches to the vacuum solenoid that leads to the valve had been previously broken off from the solenoid and the nipple had been jerry rigged back together. Fixed with epoxy and tested for leaks.
Continued to look for other problems and found that front radiator support had been broken. Front bumper was loose and radiator was being pulled forward, so was the intercooler, making the turbo piping stretch and not seal correctly. Front radiator support is being replaced so pipes are not stretched and caused to leak.
All of these conditions come from a car repaired badly and someone not knowing how to do the work correctly.
I am now hoping that after all these things are corrected, the car will hold boost and run properly. I will update you guys when I am done!
