Hello,

I just started having problems with my car going into limp mode during harder accelerations. Yellow engine light (half filled) comes on and goes away after a few seconds.

Getting codes 483C(boost pressure plate), 4990(exhaust pressure sensor before turbine, plausibility), 4530( boost pressure control ,control deviation)

I had my car in the shop to fix a leaking (rear)brake pipe, during this they moved the exhaust system and it broke at the flexpipe due to rust. They took it in again and welded a new flexpipe to the dpf. The dpf was removed from the car to weld and I’m suspecting something happened during this that could cause my problems?

Any insight at all would be very much appreciated!

Thanks

Check everything is connected properly at the dpf. Particularly the pipe for the exhaust pressure sensor.

Failing that, it could be the turbo actuator...but hopefully not.
