Exclamation N55 Fault Code: 2C58H/11352

Greetings all,

My coupe's engine light has come on with the car going into limp mode, the problem comes and goes. I've taken it to the Indy garage that does my servicing and it's thrown 11352.

2C58H/11352
"Boost pressure control, deactivation: boost pressure build up blocked"
"The diagnostic function monitors the DME's deactivation of active boost"

I'm thinking Solenoid, Wastegate issue, visually checked my OEM chargepipe which doesn't have any cracks.

Anyone got experience dealing with that code? Help appreciated, i'm thinking of booking it in with the main dealership but would like to avoid!

Appreciate 0
