Strange issue, looks like SMG CU trouble?

[Kislik]

driving round the ring, made 2 laps to warm tires and than 2 fast laps and started 3rd. Than in one corner engine stopped, SMG light went on, brake sesnsor on, dsc of. Zero RPM. went to neutral in the smg, than back. engine on, errors still there but works. little later same again, always in right corner.

stopped the car, switched of, started. no errors. went back on track and again and again in right corners. slowly finished the lap with errors on. went to garage, engine ECU checked and ok, smg tested clutch adjusted but not possible to read anything. error still present on dashboard even after multiple starts ... leaved the garage just to go around, lights of, no more sign of error. drove it back home over 500km with not a single issue....

any help? see the video how it looked

On the right side of your engine is an earth strap, (Offside of car), it attaches to side of head. I had similar issues when Murketts left this loose.

Worth a pop.

Also check battery terminals in boot and under bonnet.

good points thank You. have to mention that that there is light battery and suspension kit was installed on Friday (day before this has happened). will try to check those points if something is loose

many thanks, it was battery loose. There is small light battery and my mechanic made some holder as it's a lot smaller than original. This broke and the battery moved freely inside. Did not hear it on the track :/

anyway no other demage, all looks good. THANK YOU for help
