View Full Version : A6 Multitronic Gearbox Problem ?

I have an A6 Avant 2.5 TDi SE with the multitronic gearbox; model year 2002. The car has fairly high mileage (146k) but has been regularly serviced with Audi at each regular service interval.

The gearbox has always been incredibly smooth (one of the reasons I like Audi so much - i have two A6's) but over the past 3-4 weeks the car has been juddering at pull-away. Also, once you reach a constant speed (whether it be 40mph or 70mph) the car is "blipping";- that is, the rev counter bounces and although the car does not lose speed it has a blip as though to change to a lower gear, then corrects itself and stays in the gear already being used.

I wondered if the transmission fluid was low, but found that it was both clear and fairly full when checked.

Has anybody experienced a similar problem - I blanch at the thought that the gearbox needs replacing especially as this has not happened gradually, but almost overnight. As a second owner, I understand that the car previous had done high motorway miles which is not that condusive to gearbox wear.

Any suggestions or could be something completely unrelated to gearbox ?

Hi Scottnd

You might like to give these guys a call:

I have no connection, nor have I ever used them, but it seems they might know exactly what your probs are.

Did they checked the fluid with the gearbox at the normal operating temperature(about 80 degrees C oil temp) also were any faults in the module memory ? Oil level should be no more than 5mm under the filling plug level. Another thing to do is adjust the pedal position sensor trough diagnostic equipment, check www.rosstech.com for the exact procedure. First of all they should figure out if the fault is electrical, mechanical or hydraulic. If there are no fault codes in the memory, i would check the iddle speed control module(but that will have the rev counter bouncing all over into neutral,wich i asume it does not !). Also look for sticking brakes as they would do similar signs. Have the car scanned for fault codes first and if any present, post on the forum...Good luck.

My father in law had exactly the same problem on his A6 2.5Tdi.

It's a long story how it was finally resolved, BUT, the muti-tronic gearbox you have in you faulty vehicle was subject to a replacement gearbox, IF your gearbox failed prior to the warrenty expiring.

This is because your particualr muti-tronic gearbox is unable to cope with the high torque produced and over time is subject to failure. Audi realised this and modified the muti-tronic gearbox by adding another set of clutch plates/slipper rings to the gearbox to make it cope with the high torque being produced by the engine. This was not the subject of a recall, even though a design fault was known to exist. Only those vehicles which suffered this problem prior to warrenty expiry had a replacement/modified gearbox fitted free of charge.

In my father in laws case, even though his warranty had expired by about 6 months when he sufferd this problem, he managed to get Audi UK to pay half the total bill, (total bill came to £1400), because his dealer had failed to change the transmission fluid at the recommended interval as specified in the handbook, even though he was charged for the work and the fluid! His A6 has a full Audi Service History and I believe failed at around 40,000 miles when the car was 3.5 years old.

My technical explanation of the gearbox working may be slightly incorrect but it is along these lines that the failure and rectification takes place.

Hope this helps,

As A6 LeMans mentioned, I have the same problem. The blib will become a shudder in 2 or 3K miles and any strain on the gearbox causes shudder. Only a very sedate drive or drive steadily at a higher gear that the one selected by the auto stops it. My case is on an A4 late 2002 multitronic now on 108k miles and always serviced by the same Audi dealer -in Slough- and could have been caused by them not replacing the transmission oil until it had done some 90,000 miles! It should be done at 40k intervals..Problems started at 100k and misbehaving thereafter! Not so lucky as LeMans with dealer sofar. For its replacement they asked - after some haggling - £3900. I would be more inclined to repair it but have not yet done anything. Repairers say that Audi are witdrawing the multitronic as too problematic and going for the straight 6 gear automatic. Such a great shame - it was a fantastic gearbox.

Thanks for all the advice sent on this forum ... apologies to all for not responding sooner but I didn't get the problem fixed until the week before Christmas.

As Teutonic_Tamer noted, there is an independent in Milton Keynes who understands the problem and has the experience to fix it; I tried several local autobox specialists locally, but non wanted the job as it is too difficult, requires specialist tools and the "insignificant" parts such as bolts are not sold individually - a problem if something not related to the job inhand is broken during the process.

Basically, the problem is that the six point clutch on the 2.5 tdi cannot handle the torque and as such an upgrade to the seven point clutch (as fitted standard to the new A6 2.7 tdi) is required.

Inde-tech do this in a day, reprogram the engine management system to recognise the new clutch arrangement and for half the cost (£750 + vat) of an Audi main dealer.

The car now drives as before and hopefully will be good for the next 100k miles. Thanks to Teutonic_Tamer for providing the web details and to this website and members for helping out.

Merry Xmas & happy new year ... although the kids only got oranges and a lump of coal after the £881 bill for the car !!!

No worries, at least you had the good decency to post the solution to your problem, unlike someother posters, who ask questions, but never come back with replies.

So, the Multitronic does seem to be a rather specialised beast, but it is good to know there are specialist independents out there.

fx/on <raises eyebrows> fx/off - that's interesting!

What kind of warranty do Inde-tech provide? The cost from them seems quite reasonable, especially compared to the £3900 from one of the other posters - owch.

Good to hear. What about oil changes though? Did Inde-tech advise on changing the 'box oil sooner than the manufacturers schedule? I'd be inclined to get it (along with the filter if it has one) changed every 40k miles from now on.

Seasons regards to you also. You'll have to take the kids on a long drive to Paris Disneyland or summat similar, extolling the (new) virtues of Audi engineering excellence and refinement. :D :D :D

I have an A6 2.5tdi 51 plate 101k miles, with the same juddering at pull-away and blipping at constant speed. Reading Audi prescribed a new 7 plate multitronic clutch, at £1500. The second multitronic oil change on the car was 9k miles too late, and that, coupled with the high mileage and warranty expiry, meant Audi UK were not willing to contribute to the cost. Local auto box specialist did not convince me he knew multitronic and really wanted to sell me a recon box at around £3.5k.

I found Inde-tech Milton Keynes on the web. They supplied and fitted the upgraded clutch for £750+VAT. Car now drives better than it did before the clutch failed - quicker take-off. They seemed to be good guys who know what they are doing and specialise in this job. It was well worth the hour and a half drive to get there.

Hi all - appreciate this is an old thread but sounds relevant to me. I have bought a 2004 1.9 TD9 multitronic which has started shuddering when you pull away from standing / junctions and recently started to shudder a little at a constant speed of 40 mph. Looks like inde tech are the place to go from this and some other threads i read. I assume no one has newer information to suggest a better place or alternative solution?
