Audi's MultiTronic Gearbox

[yeedes]

Thanks for that Tame Technician. Much appreciated. I was just referring to a previous post mentioned on page one. However, I think this referred to an A4 (possibly older) and maybe the earlier sensors. I was told that I shouldn't really have probs with the 2.0 petrol as the box ought to be able to handle the torque from the lower power petrol models. I guess there is an exception to every rule... Is it right that there isn't a seven plate modification etc. for the petrol cvt boxes? (only diesel?) I guess if not then I am looking at a new box that would outweigh the value of the car by some margin. Any thoughts and adivce (other than get rid ASAP) gratefully received. George

I am waiting to collect my B6 A4 (04 registered)from the auto. gearbox specialist, and will be £2650 poorer. This chap has been in the game for years,and has had to repair loads of these boxes. The 7 piece clutch replacement was produced by Audi to get over their warranty claims, but this does not cure all the problems. Dirt in the box wrecks plastic components, and thrust bearings have to be replaced as well. The box is a brilliant concept but badly designed and ridiculously expensive for parts. Changing the oil every 40k does not stop the problems. Audi refuse to acknowledge any of the additional problems, so unless you have a good warranty, be warned. He is not convinced that new ones won,t develop problems either.

TT (+others) - Does this problem also affect the multitronic versions of the A8?

If there are any A8's out there with them in, then YES, But I've never seen one.

The gearbox wont work as hard with 2.0 petrol torque to deal with. Without actually entering a valid vin number and checking the TPL's I cant be sure if the mod if relevant to petrol cars, worth a call to your local dealer to ask. They wont know, so ask to give them the vin or reg number and have them find out and call you back.

Interesting. Considering a 'new' S4. Would prefer to buy a nearly new/demo one but they all seem to have Multitronic, and Id prefer a manual. Guess Im best off searching some more or biting the bullet and ordering a new one (as much as it would pain me to do so)?

[Tame Technician]

S4's new or old, would never have multi tronic. Multi tronic is not fitted to quatro cars.

Older S4's are tipronic and the new new one is S tronic, you know double clutch like DSG in the TT's Golfs etc, only redesigned to work in the bigger cars.

There's at least 3 in the classifieds. All 3.0 petrols I think.

Ah, I knew it was somethingTronic lol. Any good? Suppose I should really go try one

[Tame Technician]

The transverse mounted DSG/S-tronic in the TT's Golfs and A3's are a little bit fragile at higher mileages, mechatronic units fail quite alot.

The longitudinal mounted S-tronic box that is in the new S4, and will be rolling out in all the other Audi's of that layout over time, Q5 already, probably on S5 cab too. Is a significant update and major redesign. Its to soon to say how reliable it is, but the jerkiness that plagued the old one has now gone and the gear shift is faster and smoother than ever, so YES seems pretty dam good to me. Its 7 speed instead of 6 now also.

hello, im having problems with my a4 04 plate 1.8t avant - flashing gearbox lights on dash, losing reverse.

my scenario is that this car was purchased from an audi dealer in tonbridge,37k, fsh, 1 other owner in 2007. I fortunately opted to buy the 3 year extended warranty.

The gearbox was replaced within 500 miles of me owning the car [mileage now at 37900 and gearbox number 2,] under warranty and then warrantied again for a further 2 years. The car has now done 58k and the box has failed again within warranty period which runs out in august, flashing dash etc etc.
now on my way to a 3rd gearbox. Ive booked it in to my local dealership.

ive been here before, i know they will quibble.any advice guys - im gutted as i love the car its the 190hp version, but 3 boxes within 58k??????? not good.

[Tame Technician]

Just point out that the part was fitted less than two years ago and (they will check there system and have a record of this) you were told it has two years parts warrant, And you very annoyed because also you had a failure of it before, under used car warranty, Cant see how they can quibble that.

Hopefully the 3rd one will hang in there a bit longer.

TT have you heard of any failures in the 2.7 tdi A5. I contract hire mine and it goes back after 3 years so no probs for me. But i love the car and was thinking of buying it for the wife,not so sure now

[Tame Technician]

The multitronic in the new B8 A4's and A5's is a different unit to the older ones, and they tell us a significant upgrade, we haven't seen the ECU or Clutch failures yet that were the problem with the older ones. But they are all quite new still so its hard to say.

We did put a new one in an A5 the other week, but it was a faulty unit from new, rather than one that was in service and then broke. Customer always complain of harsh pullaways, we adapted it, and it would be fine for a month or so and then start doing it again. After three attempts to fix it with software and no cure the gearbox was replaced. Car probably only had 3-4000 miles or so on it.

hi tt,
update - audi reckon the ecu has gone [under warranty, no quibble as the sales manager admitted there was a fault with them]

my question is he mentioned that for my model of car they have upgraded the replacement ecu's, clutch parts etc...is this true or am i just going to get a replacement that will be the same?

[Tame Technician]

The new ECU may well have later software in it, and when you had the gearbox replaced before, it is likely the new box had the upgraded 7 plate clutch pack. I dont know how you would check this for sure, probably the gearbox part number could be referenced.

But I'm not sure other than the usual software updates that the ECU's we put in are any different to the one's we take out.

Hi all,

New member here, i've recently purchased as Audi A4 cabriolet 2.4 multitronic on a 52 plate a high miler at 98k miles. I'm starting to think I have issues with the gearbox, ther's a judder or slight hesitancy when aceelerating from low revs but not from pull away. servive history says gearbox oil changed at 40k period but not since then.

What would be the best step to take? Can a gearbox oil change ever cure this judder/stutter or could it be non gearbox related?

Thanks in advance

Andy

May not be the gearbox, could be an engine misfire.

The common gearbox problems are judder on pull away from standstill, and a kind of hunting/forward and back rocking motion at 40mph light throttle. If its not either of those, probably not the gearbox.

Try driving it in manual mode for a few days and see what sort of throttle positions and engine speed the problem occurs. If its large throttle openings at low rpm, then its almost certainly engine misfire. Does your engine have individual coil packs or the old fashioned twin coil and leads??
