Gear changing was bad - worse after oil and filter change

Ah yes, that's what we were trying to do

Did he come back with his BS? I dont think he posted up anything after asking how he would know what box he had fitted.

Hi all - still here - thanks for all the info, thread has exploded! I got onto Vanmatic (ZF centre) yesterday and booked it in for week after next as I'm away next week. Though I then spoke in more detail to my mechanic today and he said they followed the full procedure to a T - level car, monitoring temp, checking level etc. Used the genuine oil and correct filter. His explanation as to why it is worse now than before is that the filter was so clogged that it was holding oil pressure in the box. The fault code is apparently 'speed sensor' or something. I may still go to Vanmatic just to see what they have to say (and because my mother in law is visiting at the time so I'll not mind getting out for a few hours....) though I'm a bit reluctant to throw more money at it if it's not going to help - my mechanic gave me a bill for £300 as it is... I fear this may be the end of the road for me and the A8.... Anyone fancy a lovely 4.2 D2 in great shape apart from the gearbox?

what's the codes on the engine transmission line ?
as you can see there should be 3 !
if you don't have the sticker in the service book there is normally one on the spare wheel well !

and £300 ? do you live in mayfair ?

OK - the code from the service book is

ABZ DNW DTD.

The £300 included a cheap tyre and a hose which needed replacing. Other than that it was £37 for the filter, £24 for the gasket, £56 for oil plus VAT plus an hour's labour - so that seems reasonable?

I'm at a bit of a loss for what to do... Is it worth spending another £200 (or whatever) on taking it to the ZF specialist? What sort of money do you reckon the whole car is worth otherwise? It's in good shape, full service history with service book, cambelt done at 80k, now got 135k on the clock, MOT to end of year. Body is in good shape. There doesn't seem to be much point throwing more money at it if ultimately it needs a new gearbox for a couple of grand - which I'm not prepared to spend.

DTD was essentially the 'worst' gearbox for A8s. I'd just drive it until it dies, as pretty much your only other option is a replacement box.

well the value of the car depends on 3 things ...condition, condition and condition

point is , it's probably heading for the breakers as is , so little value , but you can't complain at your loss for 18 months pleasurable motoring at the price you paid

but what would you have to lay out to replace it ? and what sort of guarantee would that have ? at least if you spent money on this you would know what you had and the value when you came to sell it would be higher than it is right now !

maybe a new unit from ZF/ audi would be too expensive , but there are gearbox specialists about who would fit you a rebuild with a 2 year guarabtee for a considerably lower price

in the meantime keep your eye open for a used unit with the correct code , people on this forum are good at spotting such things and will tell you if they do !

Yeah - I guess. As much as I love it, it is quite impractical for me as I travel a lot with bicycles on board and an estate would really make a lot more sense. I have and old Passat estate which is battered but bulletproof - currently SORN but doesn't need much to get it back on the road. The sensible thing may just to see what I can get for the A8 and get the Passat back on the road for the mean time. Then when I'm a little more flush with funds an A6 estate would be lovely...

I may just post it up in the classifieds here and see if there are any takers. What sort of money would you get at a breakers? I gather all the aluminium makes the scrap value pretty high? Seems a real shame for such a car to go to it's grave though
