Have had the dpf cleaned. Still has same issue
Expert:  CarDoc replied 6 days ago.

P2262 is a failure of the turbo itself or the turbo actuator, this needs to be investigated further.

P0471 relates to the exhaust pressure sensor, it could be faulty or it is as a result of the turbo fault, this sensor has 2 small hoses connected to it (please see the picture attached).

Expert:  CarDoc replied 6 days ago.

Your car is in limp mode due to these faults detected, this a safety feature which reduces engine performance to prevent damage. Once these are fixed, the engine will run normally.

The P2262 is not neccessarily a faulty turbo, this can be the actuator not operating correctly due to a vacuum leak from split hoses, actuator diaphragm damaged or the actuator arm stuck.

Hope this helps.
