Just following on from this, my 2.5 TDI multitronic gearbox I fear is giving me trouble as well, instead of the PRND flashing it lights up a constant red I can't use the manual gear change either. I spoke to Audi stealers and the chap in the service department reckons that the gearbox is damaged possibly due to the oil not being changed every 40k (mines is on 85k) checked with Audi Wearside and they reckon that on the 35k and 57k services there is no record of the gearbox oil being changed. I can't believe that this is the case, potentially this could mean that there is major damage to the box resulting in a replacement at the ridiculous price of £3500, this is not economically viable for me to repair/replace gearbox on a car worth £4000-5500.
My 2003 Audi A4 cabriolet is having gearbox problems. It's a 3.0 Multitronic with 33,000 miles and recently ALL of the PRND lights all came on instead of just the D light. WhenI select reverse, the car doesn't move unless I give it some revs. When moving from a stationery position i.e. traffic lights, there is sometimes a delay after I hit the throttle and then it jolts a few times. The car also seems a lot more noisy, with a clicking sound. 
to replace it. A few people have mentioned it could be the ECU. Anyone got any tips on what I should do now???
Best to get it checked out properly as another member paid £1000 to have the ecu changed and it resolved nothing and he still had to have the gearbox refurbed 
I did enquire about the ECU unit and they confirmed it was fine. It's just the gearbox that's faulty which apparently has metal filings inside.
Thanks Mark :icon_thumright:
They're a little bit out of my way but worth giving a call all the same.
Had a call from Audi today, they asked if I wanted them to go ahead and replace the gearbox. I said at £5000??? NO THANKS!!
I rang a few gearbox specialists today and received quotes from £1700 - £2500 for repairs or replacement.
Think I'll do a bit more research before making a decision....
