In the cold light of the day, using my brain and not my guts I think it is not the gearbox. Last night I sent the photos to the remap company asking to scratch their brain about this is issue ( easy to blame them immediately). In the end we both agree it’s not related to the remap. We will see once the garage will have a look but I think it’s not the box at all.
Yesterday was very wet and it looked like a oil leak but today I can’t see anything there! It is all perfectly dry.
After this chat today I was confident about the issue and switched the engine on again and there was no flashing light on the dashboard. Nor messages about the box.
Suspect number one at this point is the driveshaft.
I had a Pendle remap engine and box. Pendle remap superb for engine. However I wasn’t 100% happy about the box, a little bit over reactive at the push of the pedal. Instead of using torque it was downshifting even at light touch of the box. I had a chat with another company ( well known here) and I had it mapped at my taste. Superb job. Gearbox changes even faster than Pendle and reacting to the pedal exactly how I wanted. More use of the torque when lightly touching the pedal instead of downshifting and downshifting 3 gears from 7th when immediate power is needed.
Hard to say, IMHO, if it was the map causing the issue. Additional torque added a lot of strain to the poor driveshaft and sure it didn’t help. I always had my cars remapped, the first was in 2002, by reputable companies and really never had any related mechanical issues.
Let see what is the exact outcome when the garage will be able to have a look. ( they said they can’t look at it before 31st of July).
