Iveco Daily 2007 2.3, I need an electrician specialist in München please

Hi all,
I have Iveco daily 2.3 2007 3.5t and I really need good specialist electrician to help me with EDC light and electric connection . When I start the engine, it vibrates, the vibration goes out if I increased the acceleration to for example 3-4 RPM. When I drive the vehicle, it is weak and has No power as usual and doesn't drive more than 100 km/h. I took the vehicle to diagnose it and the found fault was No electricity in nozzle 2 & 3, disturbed and not stable.
So please, can anyone recommend a specialist electrician in München where I can take the vehicle to and reasonably charge?
