Use tips: I would recommend you to not open ecu or you will damage it. You need to have experience to do that. Get VAGDASHCAN 5.29 and you will finish the job.
It is hard to damage EDC16 during opening when you are a little bit careful, you don’t have to lift PCB, only remove the cover. Not the hard way like MB EDC16..
