Don't both JB4 and Procede clear the CEL if you are running a tune? I thought this was the case. Thanks.
The CEL problem is NOT yet solved for the N55 engine... Even the piggys just put it in clear. So not really solved like on the N54 engines... The DPfix of BMS was reported to not working. Another DPfix from a user on this board is being tested as we speak...
