Hello, I've looked into various topics from this forum but I was unable to identify the culprit of my issue. Basically, I have vibrations in the low RPMs (until 1400-1500) and while going from a still stop position (disengaging clutch in first gear). Also, shifting through 1st-3rd gear I always have a thrust forward/jerk. As if I dipped the clutch. The whole car shifts forward for a little bit. Letting go of the throttle in first and second gear I also get a big jerk forwards. It's neckbreaking really.
Car is a MK5 Golf, 1.9 TDI BKC, manual transmission. Since honestly I have quite a few questions, I will number them so it is easy for you as well.
I have changed my engine mount at the gearbox. The mechanic advised to change out this partiuclar mount only. If that doesn't fix the issue then we would change the others as well. His opinion was that they are not bad at all. The car felt slightly better, not that much jerking (vibrations still present) but the same problems occured not long after 100 kms.
1) Is it possible that if the other two mounts were bad the new mount at the gearbox had worn out extremely fast?
When revving the engine, there is slight play both radial and axial but it is a maximum of 1 cm. It honestly looks fine for a diesel engine. I have changed the DMF previously, it was fine for a couple hundred of kms but the same vibrations came back very fast. The jerking as well.
2) If engine mounts are bad and there are loads of vibrations, would that wear out the DMF again quite fast?
Letting go of the throttle in the higher gears, RPMs drop for a second then go to where they should be. Example: If I drive with 2000 RPM, it falls to 1800 RPM then goes to 1900 RPM and starts decelerating smoothly as it should. Something else that I've noticed: I tried dumping the clutch in 2200 RPM from first to second gear and the result was a perfectly smooth shift. Symptoms are not always present. I cannot determine when they are gone but sometimes if the car hasn't been driven for a few days.
Please note that the transmission is a 6 speed. It was rebuilt around the time of my clutch work, no more than 15-20 thousand kms. There is no engine chatter, sound doesn't differ if the clutch is in or out, vibrations are also present on idle.
Reading this everything does lead to bad engine mounts but I want to be sure before proceeding with such a repair. Is there another potential culprit for this? I am posting this since my mechanic is convincing me the mounts are fine, but the fact is that my ride is extremely annoying and I am starting to hate my car. I would really appreciate your input, cheers.
