run the option "End Of Line Service calibratrion". It lasts about 30 seconds. A flash of error may appear on the car screen, dont worry, its normal.
Yeah - ummm... I've done this on a few cars now (you're right about the instrument panel 'Gearbox Failure' as the EOL calibration finishes/shifts through the gears).
As far as getting the gearbox working, I've been successful.
Trouble is, this EOL doesn't reset the Clutch Degradation Index - mine stayed at 12940 after replacing the clutch - and therefore the car drove very irregularly for several thousand kilometres until the ECU slowly learned lower values (it's down to about 5000 now).
Many times I tried to run the degradation index recalculation process in
MultiECUScan - which comes with directions that I've managed to commit to memory:
- Activate procedure
- Start the engine
- Do a pickup in 1st gear (earlier versions said 2nd gear) with throttle pressed ~25%
- Drive for 400 metres
- Stop the car
- Turn the ignition off, then back to MAR
This has not worked for me. When driving for 400m, at what speed? Changing up through the gears? Exactly 400m or doesn't it matter?
There is even a second procedure - "enable clutch self-calibration" - execute procedure, start engine, wait a while, switch off - which seems to run successfully (code 00 returned a few moments after starting). But this is a bit short of info as well. Does the calibration happen on the next startup? Or over the next few hundred starts as I found?
One thing I did work out - when the parameter "EOL self-calibration" says "Not performed", it means "not performed since turning the key on", and it doesn't mean "not performed at any time in the past and needs to be performed" (I thought it might have been trying to tell me that). It says "OK" immediately after performing the EOL, and will then say "Not performed" after the next start.
