    Recently my 2003 A4 Multitronic avant has developed a judder when accelerating (like the clutch is slipping) I rang a respected Dublin transmission specialist and he seemed to recognise the problem straight away (needs new 7 plate clutch modification?) and told me it would cost €1500 plus vat to repair :( Anyone else encounter this before and how much would it cost to repair in UK or Northern Ireland compared to Rip off Republic Ireland?

    Many thanks.

    Don't be so quick to pay for a full scale replacement fix. How many miles has the car done, and how frequently has the gearbox oil been changed? It has to be done every 40,000 miles, and costs about £150.

    Also, have the torque sensors been cleaned recently? That is a simple DIY job. They are mounted on the inside of the front wheel hubs, and held in place by small allen bolts. Undo, slide out, clean with white spirit or WD40, let dry and then slide back into place & re-tighten.

    Try both of these remedies first, before you commit to wholesale expensive fixes. They might work, they might not, but always check the simple stuff first.

    Good luck.

    Many thanks for your reply. The car has 52,000 miles done and to the best of knowledge has never had the gearbox oil changed. I will try these options you mentioned and hopefully it will sort the problem.

    Thanks again

    The 40K oil change is a must! You might just be lucky & get away without any long-term damage.

    I had the same problem a couple of months ago, you get a judder or clunking motion as you go through the gears. Audi Bromley quoted me £1200 Audi Stafford said they would be able to do the job for £900. In the end I went to WVC Audi specialists in Byfleet Surrey and parted with £900. The chap there said that this happens quite a bit with the 6 speed auto. If you're prepared to travel check out Audi Stafford they are reasonable on their labour costs.


    Good luck:thumbsup:

    Ok, a tad bit embarrassed as I have only found out that my car is actually has the tiptronic box and not the Multitronic. TBH I didn't think there was any difference between the too.

    Anyway, Audi have informed me that the 7 plate clutch replacement is not an option for the tiptronic so where does this leave me?

    BTW, I checked and the car had gearbox oil change at 40k

    Hang on, Larry, where are you getting your information from? It seems to me you're still a bit confused about which gearbox is which. Some A4s have a traditional autobox with torque converter, and a tiptronic mode for manual selection. Others have a continuously variable transmission, called Multitronic. This doesn't have a torque converter, but an electronically actuated & controlled clutch. It also has a tiptronic mode, but when in standard auto mode, it behaves differently from the normal auto, because gearchanges are stepless

    The thing is, a regular automatic gearbox doesn't need an oil change at 40,000 miles. So it could still be that your car does have a Multitronic box. The easiest way to tell is if you say exactly which model of A4 you have. i.e. engine size, fuel type and whether it is front wheel drive or Quattro.

    Also, take a picture of your gear change selector panel and attach it to your next post.

    Is it front-wheel drive or four-wheel drive?

    Then I'd say it has to be multitronic.

    Larry, you were a 100% sure two years ago when you posted this thread. Forget what some bozo told you today, and think about the way your car behaves when the selector is in "D". Does it switch between fixed gear ratios with a noticeable step, or do the changes just merge seamlessly?

    Seamlessly (thanks for the old post, I should have checked earlier but had forgotten as I haven't been on here in nearly 2 years)
