Hello Guest, welcome to the initial stages of our new platform!
You can find some additional information about where we are in the process of migrating the board and setting up our new software here
Thank you for being a part of our community!
Is there anyway of checking that, short of swapping for a new one and seeing if the fault recurs?
Ok, thanks for that - I'll change the pump and refresh the breather system when the car gets back - can't hurt.
Have you tried another ECU? Could be a hardware issue on the circuitboard. You never answered the question as to whether you have a M.3 tune (limited) or an M4.4 ECU conversion (much better). Either way, I'd still get another ECU with the tune flashed to it.
You didn't have these issues prior to the MAF (scaling) & tune conversion, correct?
