Like the title says - I have an 07 335i 40k miles- the ecu is still the msd 80.
So far I never had any issues with mosfets going bad so everything in the ecu is original.
I had the car tuned with a procede v5, I had to detune it because I kept getting intermittent DME mixture control codes.
29e0 and 29e1 (quick edit: these codes would appear when the car was running stock tune)
I changed my spark plugs, coils and o2 sensors and did a full readaptaion but the problem persisted so i detuned and the car is running fine with no codes again.
So my question is, did the procede v5 cause the engine light because of my software on my ecu?
and if I use MHD should that resolve my problem?
Should I upgrade my ecu first? (If i do I plan on getting a new ecu not a donor)
