Petrol/Gas Petrol B58 strange sound at idle

[Andras]

Dear all, I’m proud owner of a petrol Trialmaster with 2500km on the odo. I do have a strange ticking sound from the engine at idle that I find disturbing. Went to the dealer who told me it could be a valve or a solenoid, but no worries it is all ok. Anyone having similar experience/noises?
Thank you, Andras

It's the insanely high pressure of the injection system 350 Bar max (5076.32 psi)
