1.9 TDI AWX Engine vibration

Post by passativeyron »

Hi guys,

I’m after some advice or ideas with a problem I’ve been having.

At around 1,800 to 2,400 rpm I get a strong vibration through what feels like the engine. I can feel it when I hold the gearstick, and also through the floor/seat.

It does it when stationary, and when driving too. Seems to be worse when the engine is under any sort of load but I don’t suspect driveshaft because it does it when stationary.

I had an overboost fault before this happened, but this fault hasn’t returned. Related or not? Who knows!

I’ve had really bad mpg this winter too- much worse than last winter. I do longer trips, and am only managing 38-40mpg.

I’ve checked so far-
engine mounts
Injector values on VCDS are all close to 0
Torsion value is close to 0
Camshaft is slightly worn, but not bad imo
Clutch and dmf replaced with LUK kit

If anyone has experienced anything similar, or has any ideas please do shout! I’m beginning to lose faith in the old girl now.

1.9 pd130 Manual AWX 199k miles. If it doesn’t make it to 200 I’ll be very annoyed😂

Long I know, thanks for reading
