Mini one R56 engine no longer running

Hello together, am new here, I bought in January 2020 a Mini R56 one 1.4 with 95hp year 2008 with 162tkm. Bin hobby screwdriver and have replaced before the Tüv test the following parts: Brake complete, lamda probe before Kat, both cam wave sensors, coolant temperature sensors, spark plugs, air filter, oil, oil filter and rib belt. Chain without audible noise. Tuv passed without defects. Now to my problem, My daughter drives in the 30s zone stops at a junction, engine stops and starts no more. Starter runs, no ignition spark, when the start attempt smells like gasoline. No error message in the memory. No lamp lights up, which could indicate a fault. With second key the same. fuses engine room and passenger compartment all tested and good. Compression on all fours between 12-14 bar. Control unit submitted after verification found no error! Battery exchanged no change. Has a professional of you a tip that I could look at the still? LG into the forum, am new here.
