CEL (P0238) with Dinan Sport

Hi motorers,

I’ve had the Dinan sport for 2 years, on my previous F56 and on my current F60 without any issue.

A few days ago, I took mu car to the dealer for a maintenance, so as usual I took off the Dinan to avoid any trouble with the dealer.

When I put it back on, I got a drivetrain notification on the screen, CEL and reduced power.

I scanned the code and got a P0238 (overboost) and permanent code.

I took off the Dinan, cleared the codes, and did a routine driving cycle to clear the permanent code.

Any advice on this suddent CEL? Dealer may have updated the ECU?

thanks

Found the problem:

the connector at the module had come off and would not clip back in place. Fixed it and it runs great!
