I have the same shudder problem with my 2.5 TDI 2002. It shudders when "shifting" at lower RPM's like 1200-1400. Same happends in drive or tiptronic mode, although this is much less in tiptronic because it usually shifts at higher RPM's. However, I have no more warranty on this car, so I am wonderring what is best to do. I will appreciate all advises.
And yes, VAG diagnostic computers reports error 18149 - Clutch pressure adaptation at limit.
1. Shell I try just to replace this 5-plates clutch with 7-plates clutch? Is there some gearbox computer software upgrade needed also? I am not sure I can do this kind of service in my country (Serbia), though. Official dealer told me about some official company repairing just automatic gearboxes, but these guys told me they don't repair multitronic, just tiptronic. Does anyone know some service in Hungary or Bulgaria able to do this? Otherwise, I supose the closest good service is in Austria. Can someone tell me if this completely removes the problem and what is approximate price for the repairment?
2. Or shell I just buy a new multitronic gearbox which costs 6500 euros here in Serbia. This is official dealers price and I have to return to them my old gearbox. Is it possible to get this cheaper in some other surrounding country (Hungary, Bulgaria, Romania, Austria)?
3. Another solution is to buy another used multitronic gearbox, approx. 1800 euros, but then how I know how long it will last? And I even don't know if it already has seven plates clutch or is it old version with five plates clutch.
4. Or to switch to manual gearbox and finish with the problems? I can buy used manual gearbox for approx. 800 euros. Total cost of manual gearbox and all other parts (pedals, handle, ...) including changing in service would be approx. 1500 euros.
5. Finally, is it possible to put some other kind of automatic gearbox (tiptronic) into this car?
Please help, I am desperate with this problem.
