Bought my 2004 A4 (SE) TDI 130 Sports Multitronic for £9k in August 08......which I love. I'd like to declare now that I'm not 'car orientated AT ALL'....so please bare with me!

Firstly, "Thank you" TT for your insight - you should charge commission!

Flashing PRNDS started a few months ago after revving high then juddering after stationary and worse in reverse. However this problem can either happen a number of times and seemingly correct itself in the same journey, or not happen at all. At the moment, I'd say it happens 'periodically'.

One big problem happened on a journey a month ago - the car would only drive in 1st gear and after trying this that & the other managed to get it to drive in manual, then as mentioned, it corrected itself again.

Took it into Audi Stafford who charged me £88 to tell me that I needed a complege new transmittion & quoted £4200. It felt like someone had died!!!! The assistant in the showroom told me she'd only seen this diagnosis twice (!?) and after checking Audi for a good will reduction I was told no due it its age!


Having read all 14 pages, Im still baffled - do I just 'sell now' & look for tiptatronic ....or look to approach a local expert in the hope its not as bad as Audi say?

Extreemly grateful for any advice.

Hi Guys,
I`m also having problems with my 2003 Audi A6 ,2.5TDI Auto/multitronic gearbox .It has done 55Kmiles.Its starting to give problems on take ,its has to be revved hard and then it kicks off.

I was wondering if it would make sens eto put a mnaul gearbox into the car and if yes what other parts would I need apart from speedometer/electronic dash.

Regards B.
Dont think you would need a dash, but Engine ECU and Dash would need to be reprogrammed so they car doesn look for the gearbox ECU on the network anymore, as would the ABS ECU. I think realistically it would cost more than the car to change from auto to manual.

So from what I've read, the problems are limited to 2001-2007 multitronic boxes, correct?

Only ask as I'm picking up a new A6 multitronic tomorrow morning, brand new so under warranty and I will only be keeping it for 2 years but the reason I have gone for this is cheap(er), trouble free motoring. Hope I've done the right thing!

A6 multi box is no different today than 2006, its the new shape A4 and A5 that have the "all new" one. But dont worry the later cars are alot better, and in the highly unlikey event of you having any failures in the first two years of motoring, Audi offer road side assistance and the use of a car until yours is comletely fixed for free under warranty. Honistly it will be fine. If you decide to keep it more than 3 years consider the extended warranty options for total peice of mind.

Sorry missed this one, sadly there diag could well be right. If its wrong the likely hood of somone getting to the bottom of somthing intermitant like that is pretty slim. You could have a separate mechanical and electrical fault by the sound of it.

My advise.

Clean the car inside and out so its gleeming and take to your nearest car auction, pay the fee and take what ever it makes. You will loose over what ever you paid for it, but the £4k for a new box wont add any value to the car so get rid and move on. You would get more on ebay or somthing, but you know its gonna come back on you so auction is the best bet for a quiet life.

I'm really sorry if that sounds hash but thats not an ecconomical repair for that car.

I got my car back last night from the transmission repair place, they replaced the valve body, and the car is drivable again (doesn't stall, rev at random levels or stutter on take off).

But the original issue still remains where it would judder/bang on slow acceleration once warmed up and also having a bit of trouble engaging into reverse.

Thanks for the recommendation, I will use ecutesting.com for the ECU.

How much did you pay to have the ECU removed, refitted and gearbox oil changed ? I'm thinking of using my own mechanic as I dont know of any specialists in the London Area that I trust.

Just to keep you updated...took it to an Midlands Automotive in Kettering and they replaced the ECU for £1,200....problem fixed!

Not much difference to a £4000 quote from Audi is it!? I'm in 2 minds whether to go back to Audi Stafford and make a fuss about mis-diagnosis & demand my £80 back!!!!!

hi, I just found this thread when googling multitronics and was hoping for some advice. I just bought an 2.0 TDI A6 with one of these boxes. 07, 60k miles and, all in, a very nice motor. I've driven diesel audis for years with very few problems but this is my first auto. Test drive was fine and it came with full audi service history and years warranty.....

But (and there always seems to be a but in these postings) a few hundred miles in I've started to notice an ocassional very slight judder on coming to a complete stop and when moving off with light acceleration (1-1500) but not when braking harder or pulling away with harder acceleration. Particularly when the car is cold .

Occasionally on accelerating and coming off the pedal (like maybe on a roundabout) I hear short sound (no juddering) which is hard to describe - like a metallic sqeaking or chugging, not very loud. Hard to say where this is coming from, at first I thought it might be the suspension but I've only heard it when accelerating and coming off the pedal.

I don't know if any of this is 'normal' for a multitronic or if I'm just paranoid after reading this thread! It is very slight and, to be honest, I might never have questioned it if I hadn't read all this. I've followed up on the service history and found that the transmission fluid was changed before 40K but again at the last service (60K) which seems strange. There was also a software update to fix a stalling problem at 50K.

So, am I being paranoid? The car is fantastic to drive and I do like the multi box but now I find myself questioning it every time I get in it and worryin that I'll be looking at a hefty bill further down the line. There seem to be a few people on here with good knowledge and I'd appreciate an honest opinion.

Does it sound like a dump valve or a waste gate, if so what you are hearing is just to normal sound of the turbo in that type of load then quickly no load situation. You may even be able to replicate it standing still in park.

There is often a slight jolt or slight judder as you pull up to a stop, a litle bit like the gearbox is still pushing the car along and then finally realises you've stoped and takes away the drive completely. That is normal, but there shouldnt really be any when pulling away, but you might just be feeling the vibration from the engine, they are not the smoothest of things.

Just keep an eye on it, I dont think its anything to worry about, but make sure you book it in for them to test before the years warranty runs out, if its troubling you.

Hi,
I'm certainly not a mechanic but I once had a 2004 Audi A8 3.0 with the multitronic box that displayed the exact same symptons as your car.

I eventually had to have a new clutch pack fitted by an Audi dealership which cured it, but still cost me over £1,200, even with a contribution from Audi!!

If your car is still under the Audi warranty I would definitely get it booked in and looked at, mine only had a third party warranty which didn't cover the issue as they said the clutch pack was a wear and tear item.

The good thing is that your car has had the gearbox fluid changed at 40k miles, if you hadn't had this done Audi wouldn't want to know, even if it was still under their warranty.

Good luck with it.

Thank you both for such a quick response. I guess it could sound like a dump valve or waste gate, it is that kind of sound only I've not heard this particular noise on previous diesel Audis. But that is reasuring to know. I was slightly sus when I found the the transmission fluid had been replaced at it's last service (only 20k after the 40k replacement) and there had been some stalling issue at 50k.

Other than that though it's not had that much work done to it - a split intercooler at 30k but nothing else other than the usual. Seems like it's been well maintained so I hope it's a keeper. I'm taking it on it's first long run (~1k) this weekend so I'll see how it goes. I'll keep an eye/ear on it and take it into the audi dealer before the warranty runs out.

thanks again

I had Multitronic on my last A4 cabriolet. Bloody appalling thing. It kept effectively stalling, the only way I can describe it, and then all power would go, as you were moving along a complete shut down. This would last for 30 seconds to a minute before it could be re-started.

In and out of the garage, absolute stars at York Audi by the way, but never could find the issue, nothing showing on the system as being wrong.

I got rid a year ago and would never consider one again, dangerous piece of crap.

Hi, I'm new on here. Been searching for some guidance on my Audi issue. This thread is very informative.

I've got a 2002 A4 2.5TDi multitronic. It was an ex company car ()not mine) and had a full Audi service history. I've had it for 4 years and it has now done 150k. It has been a joy to drive and I love the performance of the gearbox, its so smooth. However, I'm now experiencing an increasingly frequent intermittent problem when pulling away. Sometimes it does it perfectly, sometimes it doesn't do anything for a few seconds (seems like an eternity at a roundabout)then the 'clutch' releases and away we go. It can be encouraged to do this quicker by gently raising the engine revs, then the clutch drops instantly and we shoot off with the accompanying mwechanical 'thud' as if my foot had slipped off the clutch in a manual car. With my limited knowledge of how these gearboxes work it feels like a sticking valve that releases more slowly than normal sometimes.

I've taken it to a gearbox specialist who has checked the coding and found no error messages. The oil level was correct and looked clean. It was changed at 80k but can't see that it was done at 40k. He mentioned changing the ECU but couldn't guarantee that it would resolve the issue. Parts and labour would be close to £1200. Not a cost effective option on this car! I'm considering getting the gearbox flushed and gearbox oil (& filter?) changed. I've also read on here that speed sensors can be an issue. Any other suggestions?

I love the performance of the car and gearbox - when it works - but wouldn't buy another with a CVT until the reviews of the newer models show a clean bill of health.

Well, I was repoting similar problems last year with my A6 2.5TDi Multi. It would shudder on light pull away, and once or twice lost drive with a loud cluk clunk. Through the winter the problems disappeared, but now (warmer weather?) it is creeping back. Its OK if you accelerate harder but shudders on light pull away. I wonder if the oil viscosity is lower in the warmer weather, and fresh oil might improve it. It will be due for a service soon, so I will prob get it changed then. Has full Audi service history, but no mention of oil changes.

Hi everyone!I just recently bought Audi A4 04 plate tdi with 6 speed auto multitronic gear box and allready I am having problems with it.
Driving ranges always flashing and doesn't show in which gear its in D or R or N nothing at all,also it kicks out of the gear while driving or stalls the engine when break to stop the car.I phoned up Audi dealer and they told its gonna cost me over 800 pound to replace ECU (CONTROL UNIT )but I have done diagnosis and it came up with fault code P 0706 DRIVING RANGE SENSOR,does anyone know is it possible to replace that sensor without changing the whole ECU?
Please help!
