Hi all,
My 645 has been sat on the drive since lockdown. This week before driving for MOT, car sluggishly fires up but looking at the Live data on Carly app, I saw the voltage was dropping, generator not working and slowly the car went to limp mode. As the revs was dropping I tried to rev up. I Was trying to keep it alive but it died anyway.
long story short, the battery has now been charged up, generator working ok. Only, when I reverse, the car shakes a lot and surges. When on the motorway and I put my foot down, it surges a lot before revving up to desired speed.
I thought I’d use INPA to check for engine backfire but it look ok. I said ok because it doesn’t return any code for engine backfire. I did live running data on INPA looking at the analogue 1, 2 and 3 data.
I have some pictures attached and I’ll appreciate if someone with experience of INPA and backfires to help explain if the analogue readings are ok or I’ve f*ked sheet up by revving the engine when in limp mode.
The MOT guy says the car is in good shape which I love to believe but having used 3 of the 645’s I can sense when something ain’t right.
I’ll appreciate your opinion. See attached photos.
Thanks!
