Audi's MultiTronic Gearbox

[DomPritchard]

Hi. I just recently bought 2008 audi a4. (b7) 2.0tdi miltitronic (cvt). Love the car!! But not sure what to say about the multitronic transmition (cvt). At first didnt like it but now im getting used to they way it wants to be driven and now i quite like the multitronic.
Only 1 problem!! Somethimes the transmition will act strange suddenly revs stick at 1500rph when slowing down. Only drops under 1500rpm very suddenly before reaching a holt. Whilst the car is sticking at 1500rpm the car is jerky whilst it changes gears. And not normal to react when speeding up. only happens somethines, but i dont like it at all!!!

Hope someone can help,

Thanks Dom.

DPF regen makes it hold the revs at 1500. And the drivabilty (I would say carburation, but that not the correct term) is not very good, not at all smooth while the engine regens. If you notice it does this periofically every 600-1000 miles it could be that.

Hello everyone,
I've got a 1999 A4 Quattro automatic that drives very badly. It's good in Tiptronic mode, very sporty, but in Drive it's very sluggish and doesn't seem to change at the right times. Is that something that can be fixed?
Many thank,
Jack

Does the box still pull away cleanly and shift well at high revs? There's a chance it's a sensor fault if the shift points are strange but equally it could be slipping under torque.

The box can probably be rebuilt (speak to any ZF/auto specialist) but the cost of doing it might outweigh the value of the car. Have someone drop a bit of the oil and see it isn't full of iron filings.

I an thinking of getting a 2006/7 A4 cabriolet 2.0 tfsi. Does this model have the fragile box or does it have the improved 7 speed box. Did they improve the B7 after this year if so when is the best year to go for, and is the 40k service still crucial?

If it's front wheel drive, then yes. Quattro has the Tiptronic

The 40K oil change is required on the B7 multitronic.

Yes it does have the fragile box or yes it has the 7 speed box that does not have the problems?

Yes it has the alleged fragile box, and even on the B8 there are still failures popping up. But this is the internet, so the majority of 'boxes working fine will never get any publicity.

Unless it was a lease car/company car, I would never buy a multitronic. It would always be in the back of my head that a big bill would be around the corner. If you want an auto, get a quattro with the tiptronic box.

I would but they don't make quattros on cabrios.

Audi make the B7 3.0TDI quattro and 3.0 quattro tiptronic as a Cabrio.

Here's one of two on the Audi Approved scheme: http://www.audi.co.uk/used-cars/used-car-locator/a...

Seeing more of them through my doors then probably all bar one person on here the B7 boxes are generally good and vastly improved over the B6 item (often see A7 2.7 multis with plenty of miles and no problems). Not seen a B8 failure yet.

hi can anyone help
i have the dreaded cvt with the v6 tdi on my 04 a6 estate it ahs had the gb oilchanged at 40k 70k and 105 it has now done 115k
2 weeks ago when selecting reverse it seemed to stay in neutral so put back in park tried again and it worked then the prnds symbols all started flashing on dash so turned it off and started agin it was fine
then today it did it again and i have driven it with it flashing and it drives ok but i noticed when slowing down at slow speeds ie in traffic it seemed to slow down more sharply as if the gear box was tight.
turned it off for 30 mins went back and it drives fine
am taking it to noston audi 2morrow any gueses what they will say
thanks

From my own experience, that sounds like the gearbox ECU needs replacing.

My A6 ran for a couple of months with the flashing sign - which is the system going into "emergency" mode. At first I could pull over, turn off, restart and it would correct itself, but after a few thousand miles it would typically not engage reverse.

it's simply a matter of how long you can put up with it. Personally I'd get it done sooner...

[Dr G]

...or it'll leave you at the side of the road in the snow and nobody will be able to put a new ECU in until after Christmas!

A little reminder on how important the oil changes are even on a late car; had recovered in yesterday an A6 2.7 multitronic with what likes like a dead gearbox. 88,000 miles and no evidence it's ever had an oil change.

many thanks guys
don't suppose anyone know where other than audi i can get new ecu fitted?
thanks again

Multitronic Problems:Gearbox? Sensor? Clutch?

Car A4 3.0 cabrio Multitronic. 91,000miles. Had the gearbox oil changes. no metal in the oil.

Syptoms:
All is well when the engine (and more specifically the gearbox) is COLD.

However, when fully warm and only below 1800 rpm there are problems.

Between 1300rpm and 1800 the rev counter shows a little murmuring. It goes up say from 1600rpm to 1800rpm then back again, or say from 1400rpm to 1600rpm. When warm and under low to moderate acceleration there is a slight judder. If you drive enthusiastically (i.e you're keeping things well above 2000rpm there are no problems, and as I said everything fine when box is COLD.

Car comes to a standstill fine.

When warm car feels like it cannot fully make its mind up what ratio to stick with. Any bright ideas? My usual aftermarket audi garage doesn't touch them!

Someone mentioned some plastic component inside the gearbox affected by the viscosity of the oil and keeping belts at correct tension at [e-mail]

cheers folks

Hello guys, just want to start by giving Tame Technician a big thank you for all his fantastic useful information your a legend. Reason being a couple days before purchasing myself a 2004 68,000 mile Audi A4 Avant 1.9 tdi I thought I would do some home work first and came across forum with all this info and I'm so glad I did as before I bought it I done all my homework and was so lucky to find it had a full Audi service history from my local Audi garage just one owner already had the 7 plate clutch upgrade last year along with reassembly and clean etc as well as the brake upgrade, it also had gearbox oil change at 37,000 but if it wasn't for tame tech I'd be none the wiser and gone in to the sale I blind man, So a big thank you TAME TECHNICIAN as I have a little more piece of mind now with my purchase not to say it won't go wrong but obviously it did and had all the necessary repairs so fingers crossed. And just to add that the car drives like a dream and had no problems so far. Thanks again. Ashley Cockerill

Been offered the MultiTronic box in the latest verion of the A6. The alarm bells were ringing, any cause for concern? or steer clear?

[Max M4X WW]

My parents have a 1 month old B8 A4 2.0 TDi Multitronic, its done a couple of thousand miles.

When reversing from cold up a slight incline you have to press the throttle quite a bit to get the car moving, with a lot of revs. Usually auto's start to creep quite easily with little revs.

Does this sound normal? They took it back to the dealer but they said it was normal. They don't think it was quite the same when they first got it.
