I have a problem with my Audi A4 2.0 2004 Multitronic.The juddering is felt when taking off and it goes on as long as i am lower than 2000rpm. The rpm also jumps up and down when below 2000rpm. When above 2000rpm the car drives fine and the rpm is stable. Today i went on manual mode and the car drives just fine, it jumps a bit but i think its normal.

Has anyone experienced this type of problem? any ideas, is this a gearbox problem or something else? i have tried many forums but no one has a clear answer. Someone has suggested spark plugs…

 

from what i gather online its a transmission issue.

However scan your car for any faults or codes

Check the gap on your spark plugs.

 

i replaced spark plugs with new ones yesterday. No change, the problem is still there..

 

i looked at audizine for a good while and people seem to think it is a tranny problem. Ar you CVT?

 

yes it is CVT fwd

 

CVT on B6 are well known to have a lot of issues and to fall appart every 40k to 60k km.

 

More trouble now. The juddering is getting worse. The car jerks violently every 5 seconds. As it jerks you can also see the rpm fluctuating. When changing the spark plugs i found some oil in the plugs. What are the effects of oil in the plugs chamber? Apparently a gasket was missing (due to negligence of the previous owner) and the oil was leaking into the spark plugs chamber. Can this be cause of my problem?

 

i scanned my car. no faults were reported.. i planning to change the transmission oil. is this advisable?

 

your valve cover gasket has gone bad. Its about $50 for the part and its common to go back at this milage. Mine did. As for the oil leaking it its not horrible because its more then likely slow however it would probably cause you to burn some oil and possibly foul the plugs.

 

And you need to take your car to a mechanic, audi/vw specific.

Bottom line is it sounds like your tranny is crapping out. From it seems a rebuild is $3000-4000 and new tranny is closer to $8000 in America/Canada.

So asking around a forum isnt going to help much since its not a cheap fix.

good luck
