@Michael II and all other PD experts

Hello Michael II and everyone,
I'm still having the problem with my Alhambra, it's still shaking.
Therefore, I'm re-posting a shortened version of my text from the archive, because a new dual-mass flywheel has now been installed, and the problem still persists.

'I went skiing in South Tyrol over Easter. The automatic transmission wasn't a problem until the Brenner Pass. At the toll booth, I shifted into 2nd, 3rd, and 4th gear, and I thought the engine block was going to jump out (jerking, knocking, vibrating), then it went back to normal speed, and the problem disappeared. This happened every time I stopped and had to accelerate again. If I took my foot off the gas, the jerking stopped. My first suspicion was the mass airflow sensor (MAF), but it's accepting gas and also reaching maximum speed. It initially occurred sporadically, but then it happened more and more often. However, SEAT is apparently not aware of this issue yet.' During my research on the internet, I came across tdi-ruckeln.de, where my error is described in detail.

'On Saturday, I actually managed to drive about 25km without any shaking, but as soon as it seemed to warm up, the shaking started again. I then left it standing for about 3.5 hours, but it started shaking right from the beginning again. I've been driving this lemon for over three weeks now and have already taken it to the workshop four times. They've also used a VAG-Com diagnostic tool, and the abnormal readings they found seem to point directly to the dual-mass flywheel.' New suspicion: Is it the powertrain or the transmission?
My workshop is at a loss, and a SEAT engineer is supposed to take a look at it (but he won't be coming for 2 weeks).

Vehicle data: SEAT Alhambra, Pump-Düse; 85kw TDI 6SG, manufactured in July 2001 (model year 2002), without chip tuning, 15,000 km mileage.

Please help me.
Kurt.

...My friend had the same problem with his Fiat Uno about 10 years ago. But it wasn't a diesel. We were searching for a wolf back then.
The cause was: a loose cable on the electronic carburetor. Because the engine is mounted on flexible supports, there was always no contact when starting (due to the tilting of the engine block in the bearings), resulting in endless jerking.
I can also imagine that a similar problem might exist with the electrical connectors, for example, at the injectors/control unit. Have all the cables and connectors been checked here?

Best regards, Rainer.

PS: I've corrected the entry; when you're under too much stress, it's better not to write anything.

Hello,

Check the error database and PD stuttering.
Another possible cause could be incorrectly installed PD elements. However, to the best of my knowledge, this has only been observed in approximately 10 vehicles.

If the error memory is empty, first check the fuel supply (see the error database for details).


Bye.

Michael II.
