Rough idling when accelerating; incorrect PD element??

Hello everyone!!



As I mentioned in my first post, my AWX engine is experiencing a strong vibration when accelerating (similar to misfires).
Always at the same RPM and only when the engine is warm (oil around 100 degrees).

Now I think I've found the problem:

'I recently replaced a PD element, and now that I'm working on it, it's not possible to simply replace it.'

Fact: I now have three 'old' elements with ET-No.: 038 130 073 AN and one 'new'
ET-No.:038 130 073 Installed in the ZK.

After visiting a friend at a VW dealership yesterday and looking at which parts are actually necessary, we realized that there are actually four
Must be equipped with parts bearing the ET number: 038 130 073 AR.

The following system note was also recorded in the AKTE catalog under ET-No.:

This sentence is used to specify that parts 038 130 073 are to be completely installed in the vehicle.
038 130 073 AR to be changed.

Can I actually use three 'old' and one 'new'?
Do you also think that the shaking is caused by this?
What would you do now?? Install an old one again??


Best regards, Dirk

yes, I think you must have already answered it yourself.
'They must have thought about something when they completely dismantled it.'
'It probably means that something was replaced or improved in the part.'
'You'll probably have to go through it anyway, or find an older one.'

However, it could also be due to something else.
