Audi A4: Severe Shaking/Jerking - AWX 130PS

Hello, I now have an Audi A4 from January 2005 (the latest model) with a PD engine and 130 horsepower. I think the engine code is ABX, but I'm not entirely sure.
Okay, so the engine shakes when idling when it's cold, but very severely – that can't be normal. It then has an idle speed variation of up to 300 RPM! Also, it makes a lot of noise. VW said it's the piezo injectors (PD elements)... Could it also be something else? Oh, and when it's warm, it idles well, but if you give it a quick burst of throttle, about 5 seconds later it drops briefly by about 200 RPM and then runs normally again.

The error memory is empty.



Can anyone tell me more about this?


Thank you so much in advance, see you later...
Please provide the German text you would like me to translate into English. I will then give you only the translation, without any explanations.


Best regards, Chriss.

Okay, I'm ready. Please provide the German text you want me to translate into English. Just paste it here, and I will give you the translation.

Thank you... Cry...


Sure, here is the translation of the text from German to English:

'Note:'
Do not use part numbers with the index Q or AN. For vehicles of model year 01 (without WIV), an additional 4 other rocker arms, part number 038 109 451 B, must be ordered. To prevent damage to the swingarm axle (pivot arm axle) after only a few kilometers, it is essential to perform a swingarm alignment using a dial indicator.


What is WIV?

Best regards, Chriss.

Maintenance Interval Extension

Thank you...
And how do I recognize that?
Mine was always every 15,000 miles for the inspection.

Best regards, Chriss.

To my knowledge, the AWX engine in the A4 was only available from model year 03 onwards. Since yours is from 2001, it has fixed intervals of 15,000 km. No WIV (variable interval service) is possible.
