My son’s 06 Golf TDI with BEW engine and Tiptronic at 311,000 kilometres has developed an issue wherein it gradually slows down on long uphill grades, the engine starts to shudder and he has to pull over to travel with the semis as the Tiptronic shifts down and down as the car slows. The TDI will continue to shudder thereafter at all loads, even at idle. It will not smooth out until the next time it is started and not always then but usually.
I checked the MAF and snow screen and inlet filter, turbo plumbing, wiring and vacuum lines. The car has had issues with rodents chewing the wiring and hoses over the years but nothing lately. Changed the fuel filter. The belly pan has been wiped off and lost three times over the years so now we’ve been running without one. The three wires to the Wastegate actuator are okay. Tried unplugging the MAF but the engine wouldn’t even start.
Scanned using my VCDS and again at the repair shop, the only recurring codes were P2564 and P3007.
The other codes that it had at the shop visit were logged as intermittent and that were cleared and did not reoccur were P1667 (#2 injector), P0102( MAF signal too low) and P0302(#2 misfire). They also checked for camshaft wear but there was none.
Troubleshooting revealed that the wastegate actuator would not hold vacuum and unfortunately it was a KKK turbo so we installed a new VNT17.
Now the car has plenty of pull initially but is still eventually shuddering and losing power on long grades. Back to the shop, they think the EGR and disconnect it but no change.
The only other issue with the vehicle is water ingress onto the right, front carpet, bad enough to freeze purses, backpacks, etc., to the carpet and cause frost on all window interiors overnight. The car does not have a sunroof and the cowl drains are clear.
I don’t think that could be related.
I hope my colleagues here can help us out.
