Lazy as hell in 'D', and when some fun is required flappy paddle manual is awesomely addictive and fun.
IMO it makes the car for me

The B8 Multi is a different beast. I've owned a B6 Multi before that did go wrong.
The B8 Multi feels alot more like a conventional auto, the 'S' mode is very good and actually simulates an 8sp gearbox and as Pitch said the manual mode is superb. Changes are DSG quick.
Hi V Mad,
Looking at how the Multitronic box works it does seem its the best automatic ever designed ie very few internal parts its in the right gear/ratio at any given time so is MORE economical than a manual. What i cant understand is given all the above why Audi have not sorted out its problems as surely the Multitronic box is a winner when it works that is
Cheers,
Chas.

The bearbox has much lower losses than a conventional auto, and because the gear ratio can be chosen exactly you always get the best performance unlike a manual.
From what I have heard, the failures are unnecessary, and could be eliminated by imroving build quality etc. Perhaps in time it could become a winner, but if Audi keep acting as though nothing is wrong it will surely go against them.

Hi like the CVT gearbox, it's a great match to the 2.5 tdi.
My main issue is the reliability of the system.
I can understand after 100K also mechanical failuire can happen, but what I cannot understands is why an ECU needs to be replaced.
Do we know which part of the ECU breaks? Is it not all solid state in it?
I am going to have the ECU changed at 120K and the 7 plate kit was fitted at 90k

Just a quick note. regarding the newer A4/A5 multi tronic.
SO far only one of the newer multi tronic box has gone wrong (was at low milage suggesting a one off build problem) and it was in a 3.2V6 A5. A car that really should have been quatro, too much power for the front wheels. We've done few oil changes at 40k (new type of oil for this one too) and up to 60k miles or so on the higher milage cars, so we shall see how they go beyond that in time.
Regarding ECU's
ECU's just go wrong, fact of life, weather there Engine, ABS, phone, or transmission control modules. There are lots of bits on those circuit boards, you never had a mother board go wrong on your PC? or a mobile phone throw a wobbly??

With a mobile phone is usualy turn it off remove the battery for a few minutes and next time your power back it's working again.
If the same thing happen to the ECU of a car that old, I wouldn't mind so much.
On the subject of the ECU, last night I had to move my car, a couple of hours after I arrived home from work (50 odd miles)I had the flashing display, moved the gear lever a few times up and down and it cleared it self.
Ii that typical for an ECu fault or could it be something else?
Cheers
Jack
That is pretty typical.
Part of the ECU's function is to monitor the position of the gear lever, and the part of the ECU that does this is described as the multi functional switch. It is an intregral part of the ECU and cant be replaced separatly. It sounds like this is the failure you are having to me. On some other gearbox the multifunctional switch, sometime called rotary switch on the older ZF boxes, is a replaceable part. But not so on the multi tronic.
Always have a good technician check the fault memory and diagnose the fault. I cant see the car, although I'm pretty confident from your description, it could turn out to be just a siezing selector cable confusing the car.
