Hi guys... I recently bought a Lupo 3L. New accumulator installed, hydraulic orings changed, hydraulic oil changed, turbo cleaned, went for a test drive, the car went through gears like before, definitely needing a basic setting done, but Ok, not stuck in any gear, and things like that. I forgot to ask whether it had been done, so i drove back to the garage. The mechanic said "No", so he took his laptop, and started doing the settings. The vcsd was slow to respond, giving instructions to loosen the gear actuator nut and re-tighten it, the thing we ignored. The gearbox started making clicking sounds. He unhooked the laptop from the OBD connector, and the car refused to start afterwards. When in tiptronic mode, it continued clicking and selecting gears.... We connected it to vcsd again and it went through 1, 2, 3, had trouble selecting 4, and went on to 5, sometimes barely touching 4. Then the mechanic tried disconnecting the gear actuator nut all together hoping that the gearbox could go through the gears unobstructed and finish the settings, which didn't yield any results (of course: the nut requires loosening, not removing) I tried to start the car when the car was lowered, the engine started, but immediately cut off. The mechanic was in the middle of servicing another car so he had to leave Lupo for tomorrow hoping to find the solution. Any advice would be appreciated! I am now worried if any damage had been done and whether things had been seriously messed up... Before changing the accumulator and fluid, the car was going through all the gears, but was not doing it right, i guess (but bear in mind that i have never ever driven any automatic). It would hold 4 gear at very low revs, for example, then shift down to 1 under braking much later than I would do.... things like that... behaving as if a bad driver was behind the wheel of a manual gearbox car. I may have noticed that a few times the car refused to start from the first attempt. Olso, when i put the gear selector in STOP, the engine would shut off in 5 gear? What do you think about this? Why did the car have difficulty going through all the gears even before loosening (in our case disconnecting) the nut? And how to recover from the interrupted basic setting? Thanks a lot?
