Hi.
Had a cupra r for the past 4 months.
Changed a coil pack and has this intermittent problem since.
Car drives fine, hits 22psi according to my boost gauge and holds boost fine. But every now and again with no warning the car dies. The TCS EML and EPS light all cone on, just as the car dies. When it dies I have no power steering or assisted brakes either.
If I try to start the car immediately, it won't start, the fuel pump gets no power and there is also no power over fuse 28. The relay has been tested and is fine. I have cleaned the grounds under the battery.
If I let the engine cool for about 20 minutes it normally starts up fine, and I have no fault codes stored at all.
This happens every 100-750 miles, and is super random, it happened today after driving 2 hours all under 3k revs.
My immediate suspicion is the crank sensor. Of not some other electrical problem. Anyone else have any ideas.
Cheers
