Hi All

my 2013 A5 3.0 Quattro Auto has strange vibration/shudder only when it gets to 90 degrees ( normal operating temp)

it is really noticible in idle when reversing, but also in first. Have noticed it is vibrating slightly now in neutral but not as bad.you can hear it, and feel it through the seat and steering wheel.

audi have replaced gearbox as a gesture of good will and will be doing engine mounts next week, however, I am still not convinced as it feels like a loading issue and not something coming through mounts.

only 10.5k on clock.

have had mention of DFM or clutch, but any other ideas or suggestions would be very helpful as it is driving me mad.

look forward to any help

Cheers

jim

 

 

 

Have you had the A5 remapped? 

Hi Dan

no.

cheers

Then at 10k I would be surprised if the DMF has packed up that quick unless you drive like Hamilton everywhere.  You sure this is not a misfire then especially as you can feel it at idle?

However, if you say it is most definately worse when reversing then my gut says clutch. It's hard to help in these situations though without driving the car myself, sorry.

DMF's are unusual things though and they can mimic misfire symptoms. I have very limited experience with DMF's personally as everything I drive at the moment is either automatic or too old for DMF.

Good luck with it though.
