Hi I have a 2008 get TDI 170.
Had head gasket changed with belt an ever since car has vibrated under load an had bad idle.
No codes or lights on dash
Had wiring an 20 hours diag on it, new manifold, fuel pump in tank, tandem pump, injector wiring loom, new injector oring kits,new everything.
Had timing checked an done but no matter what is done it still shakes in acceleration, mpg is really really bad an has lack of power.
Seems to be over fueling really badly. No codes for injectors but is really getting annoying as nobody has any clues who looks at it.
Anybody got any ideas what it could be?
Thank you

Sounds like you need to do the zip tie mod. Is the turbo actuator actuating correctly?

What mod is that? Don't think it has been checked, but will get it looked at this morning!

Where is the crankshaft position sensor on your engine?
