2008 audi a4 (b7) multitronic (cvt) issues!!

[DomPritchard]

Hi, new to forum..

Just recently bought a 2008 audi a4 2.0tdi, great car but i have come across a (hopefully) small problem.The problem i have is when i am driving, the car somethimes suddenly plays up. Believe it is the multitronic transmition (cvt). What happens is suddenly when slowing down using break or no break the car tries to stick at 1500rpm and car becomes jerky. Only time it drops below 1500rpm is when you are almost at a complete stop. It does still change down gears hense (jerkyness). This problem does not allways happen! But when it does i hate it!! Very unpleasent to drive!!

Really hope someone can help,

Thanks Dom.

Hi adyady1066, thanks very much for your reply, i cant seem to find the dip stick to check the transmition level do you know if i have to take the plastic cover off?? And do you know if there is anything apart from level i should be looking for e.g colour?

Thanks Dom

Thanks for your comments

Just taken my audi to the audi workshop, they have changed the transmition oli.
Car does seem to be driving better now
I dont think it should have been low on oil tbh. Was last changed at just over 60,000km. And now the car had done just over 76,000km. Also says in handbook it should be changed at 60,000km. So it should have been ok.
Changed it anyways.
Really hope its all sorted now, ( fingers crossed) once again thanks for your help guys

Hi people...
Just taken my car out for a test drive too see if the oil change has fixed the rev issue. Well the answer is NO but the car most definetly has improved after the oil change. The Car drives very smooth now and i can really see why (some) people love audi's multitronic transmition.
I did forget to mention in my first post that when the car is miss behaving (revs trying its best to stick at 1500rpm) its only lasting aprox 5-10min then suddenly stops.
Also i dont understand why the car seems to never miss behave when the engine/car is cold. Also seems to be a little smoother through the gears too.

Is this normal??
And any ideas what i should do next to try to fix the rev issue?? e.g diagnostics test??

Thanks Dom

Thanks for comments guys

I Understand what your both saying, but i can get my head arround the reason why it suddenly ( not allways) hold revs at 1500rpm for long as possible when slowing for aprox 5-10min the suddenly goes away even if im still driving ( so car is still still warm)

Also forgot to mention. did park the car in garage when the rev issue was happening. Went for another drive still revs sticking in at 1500rph for long as possible on deceleration. ( then car was showing cold) when after though

Seems like when it happens it had to do it for 5-10min aprox no mattet ehat i do.

Any ideas??

Thanks Dom

Thanks

Will give them a call on monday.

Didnt mention in last post but when i went for the second test drive after leaving the car in the garage when rev issue happened it was arround 6hrs later so car was cold.
But did still get rev issue for few mins

I cant make sense if this lol

Hi, no i have not been able to resolve my ctv problem i have had the transmition fluid changed buy audi few weeks ago.Wasnt cheap... But the car for sure drives better now much smoother, and before it felt bit rough like car was trying to slip into next gear, when you are slowely speeding up or crusing at a constant speed. Not any more so the oil change was worth it but the rev issue is still happening but i do feel it happening less and less often hopefully it will just go itself
What kind of issues do you have??
Maybe i can help, have read extreamly much and talked about cvt transmitions.

Thanks

Seems like you have a different problem to me. What model audi do you have?? II do know audi had much problems with multitronic transmition between 2000 and 2005. This is when they used the 6 plate cluch/ratio. after 2005 they changed to 7 plate cluch this audi said was the end of multitronic problems. I do know cvt transmitions are not the strongest transmitions arround therefore the should be very well looked after e.g changing oil.

Good luck with audi USA hopefully they can help, i do know audi get meny calls about multitronic transmitions specially in models between 2000-2005 but never admit to common faults.

Thanks Dom
