So, not so long ago I became the proud owner of a lovely shiney 2003 Audi A6 (C5) Avant 2.5 TDi with Multitronic transmission (CVT). Then about a week later I also became daddy to THAT judder. Imagine how delighted I was!!! Well, I've done a bit of research since then and established that basically Audi build this lovely big ole' V6 diesel lump with enough torque to pull the QE2, then let everyone down (including themselves) by bolting a super smooth gearbox on, connected to a clutch made from six rings of Bavarian cheese. Oh, and an input shaft made from a lollystick. You remember the ones with the joke written on it? Well, this is no laughing matter.

Anyway, I thought I'd play a bit dumb and give Audi a call for a laugh, just to see what their take on it was. The engineer was cagey initially, but soon warmed up as I fed him snippets of my vast(?) knowledge about clutch slip, warn shaft and upgrades available that frankly should have been part of a mass recall in about mid 2004. He admitted that the clutch could cause some judder, but this was fairly normal, and that Yes, there was a clutch and input shaft upgrade available through Audi. He could assure me that it had a 100% success rate, stopping the judder completely, however, he said the estimated cost so quietly, I had to ask him to repeat it twice..... circa £2500!!!

Wow

As a result of that conversation I dug around a bit on the tinterweb and saw on eBay (of all places) a fella known by the name of Alex, of Avonmouth in Bristol, though I believe he's actually Polish, advertising a very similar service for a fraction of the cost. Following a very pleasant conversation with said Fella, I am going to take my motor down there for a visit. He knew straight away what I was talking about and gave me a very warm and fluffy feeling when he started with a free and no obligation diagnostic check and road test. The bottom line, he said, is the if its just a software issue the upgrade is £220, a 7 plate clutch upgrade is £550 and worst possible case, the input shaft is Cattle Trucked, its £990. Whatever the gearbox or clutch problem, says Alex, we have loads on the shelf and this is what we specialise in, if it comes to it we will just swap for a recon box and even that will be no more than a grand. Oh and theres a 6 month unlimitted mileage parts and labour warranty.

The big questions of course are, has anyone else heard of this chap? is he as good as he says he is? has anyone else used him? would you recommend him?

I'm taking up this service probably mid June, so I will let you all know what happens. Wish me luck!

Sorry - I posted my last update on a personal message, not realising it so it didn't get to here. "Sent 29 May 2013 - 08:55 AM

Well, I popped on over to Bristol last Thursday morning and met with Alex. This guy is like a gearbox geek (in a nice way). His garage is literally a very oily wooden shed at the end of his garden, with access down a little back driveway. However, don't be fooled by appearances. After a ten minute test drive around Avonmouth, he was able to tell me exactly what the problem was. Not just bullshit though, he back up his talk. In the back of his workshop he has about twenty or so VAG transmissions, all auto and in various states of undress. He explained exactly how my gearbox worked, specifically the input shaft, showing me how and why they tend to fail. He also did a plug in diagnostic check on my car and explained the Parameters and how the ECU program upgrade can improve performance.

The upshot of my visit is that the input shaft is, as I expected, is knackered, however, Alex is that confident in his work that when he replaces my box in August for a fully upgraded (input shaft, 7 plate clutch and ECU) and reconditioned one, he will strip mine down infront of me and, if the input shaft is intact he won't charge for it. I'm not special, he does this for everyone. The complete box exchange is a grand, the input shaft alone cost over six hundred quid and the whole process though Audi would set you back the best part of three and a half big ones."

So TG1, the upshot is, I haven't got it done yet, but should be back to Alex by the start of August. So I will let you all know then. I have a 100 mile test drive home after.

He only needs two days notice so he can clear the space and will have the car for 3 hours.

Oh yeah, and hes built this 'gearbox testing station' in an old horse box that's got to be seen to be believed. What we used to call "African Engineering" when I was in the Green Stuff.

Thank you very much for the detailed feedback so far! Fascinating setup he has there.

I look forward to hearing how you get on when it's done.

Is yours juddering all the time out of interest? Are you still driving it around?

I am still driving it every day, but yes the juddering is fairly consistent now. It started off as a hic-up when pulling away but is now getting more like a good beery fart with stomach cramps. That said, I've just finished a holiday in France, chucking another grand on the clock with no real problems. Fuel consumption is still great for engine size and once it passes that first to second jump, drives smooth.

I do have one other gripe about the A6 of this age, What is it with the bloody sand-blasted headlights?? Maybe I should save that for another post on another day.

Well Ladles and Jellyspoons, I've got it booked in for a full gearbox change on Thursday. Wish me luck. I'll return to these pages on the other side.

Well, its done. I now have a car the pulls away smoothly, accelerates without a hiccup, overtakes without jumping, and doesnt roll back when stopped on a hill.

I dropped the beast off about eight o'clock on Thursday morning and after spending the day in Bristol, returned to Avonmouth around three. Having done all the tests he could in the workshop, Alex and me took the car out for a test drive. Unfortunately, on the diagnostic program there appeared to be a slight issue with the oil pressure, so back to the workshop where Alex did a bit more work, checking each of the 17 tiny pressure valves. An hour later we were back out on the road, and following about an hour more testing he was finally happy with everything.

The total cost £1000. This is for a complete recon gearbox, including a seven plate clutch upgrade, a new chain drive (?), a new input shaft and the Original ECU software upgraded. This comes with a six month warranty on the understanding that the fluid is changed by Alex at 1500 miles, 10000 miles and then 25000 miles if still in the six months. These are labour free, just the cost of the fluid £70, or bring your own if you can get it cheaper.

I am very pleased with the outcome.

Good to hear yours is going well Lee.

My 2002 3.0 cab has been very intermittently occasionally juddering. I went up this morning, Alex and I went for a test drive and the car was behaving, his computer showed everything within spec also. Alex explained that sometimes the clutch adaptation can go out of adjustment but that it can sort itself out - basically not to worry about it. He updated the software and we'll see how it goes from there. I'm not too worried about it for now though!

I'd recommend Alex if you need help with your multitronic.

TG1, seems you've definitely been lucky with yours. Alex certainly seems to know his stuff and specialises in the multitronic box. I am a couple of weeks down the road with mine now and I am very pleased with the results. I will be back to Avonmouth in a few weeks time for my 1500 mile service, but have no issues to report.

He takes back street mechanic to a whole new level, but I would recommend Alex over anyone for this type of box.

Hi Lee/Everyone,

Very entertaining read, and somewhat comical...it made me laugh!

Anyway, this is just what I have been looking for, I have already messaged Alex through eBay with a hope he can help. I have an A4 2.5 TDI (Same engine as you) and to hear you have had yours sorted is music to my ears. I have to say I love this car, the engine is brilliant, it's just a shame that it judders. I have noticed that if you put your foot down, there doesn't seem to be a problem so to get round the issue I just drive fast EVERYWHERE. However, its only a matter of time before they catch me and take my beloved license away, so before it is too late I want to get this issue fixed as I love my German built V6 beast!!

In case he doesn't get back to me, do you have a number/email you can PM me please??

Thanks,

Dan

Cheers Dan, I aim to please.

Go careful now mate, that old V6 doesn't 'alf get there quick with a lead boot. Its when you look down and suddenly realise you're doing over a ton, and you've not even got to the end of the motorway slip road yet.

Unfortunately, I only have the number on the eBay ad. He is pretty good at answering, or do what I did and just keep ringing him until he does.

Good luck with yours, I'm happy with mine and will be going back for the 1500 mile service in a couple of weeks.

You will have to let us know how it goes, cheers

Hi Audimeister, welcome to the forum,
Well Lee has not been back to say the gear box as failed so it still must be working , you have probably noticed this thread is 2 years old ,so it would suggest Alex knows what he his doing,keep us informed if you use him

Hello Davelincs,

Thank you for the welcome. :)

I have booked in Alex for next week to have a look at the gearbox for me, so will keep you updated.

The only think that was concerning me a little, was how cheap his prices were! For a full recon it is £1250. Whereas after asking around at the more well known gearbox specialists they all wanted in excess of £3000!
