Fault code P048B
Posted: Sat Oct 29, 2022 10:21 am
Hi everyone,
New to the forum.
I’ve had my Scirocco for around 3 years now, 2.0tdi 140. Nothing too fancy! Around 6 months ago the orange engine light came on so I got the car up to my mate and the diagnostic showed fault P048B - Exhaust Pressure Control Valve Position Sensor Circuit. Firstly we changed the two sensor solenoid’s at the back of the engine then a few weeks later checked the motor that operated the flap on the exhaust. That was working fine. I’ve taken the car to a few VW specialists and had different opinions as to what’s causing the problem but with these opinions there would be side effects like misfiring or the car going into limp mode, I’ve had none of these, to let you know the car is running great there’s no side effects what so ever!
Has anyone encountered the same problem?
