Hello Sewin,
thank you for the information. But at the 2018 Plus4 the fuelrelais Sites beside the relais for the immobilizer. It‘s the same relais.I ordered two of them and will change them both.
After all bespoke stuff I look forward for a happy running engine and MOG. If not the next step is the area of the key and lock.
I think it isn‘t the silly barrel at the end of the lock in cause the engine turns well, so the barrel switches the nessesary contact.
But as every journey, every step is a step forward. I hope ;-)
