I think problem is the processor. I have sprinter with same symptom and i always replace ezs for this.
In my case always wait 15min and wiper, flasher and instrument cluster go off...
I change few times ezs - copy only eep and work ok.

i was guessing that some component failure, controlling wiper circuit would have been the cause as ive cloned all data to doner eis and all is working fine..
im trying to locate another eis but having problems finding one as everyone wants to sell full ecu kit..
any other suggestions welcome..
thanks..
