P0471 code driving me mad

[ROBBIEELLIS1973]

Hi folks
Could anyone please shed some light on my situation. I have a 2011 Mercedes c250. It keeps going into a limited performance mode. I put an obd scanner on and get p0471 exhaust gas pressure sensor out of range/ range performance. I've had the sensor changed and it has made no difference. I can clear the code and it runs fine for a time without issue. Then it tends to come on after starting the car again after first use. The garage couldn't find any other faults listed. It's driving me bonkers
Cheers
Rob

Might be worth visiting an MB specialist for this one ?
Where do you live ?

Mercland in Nuneaton is the nearest Independent I’d have a chat with them

I'll see what my garage says as the sensor will be under warranty

It could be the origanal and new sensor are working fine and doing there job and detecting some other problem, some of the obd scanners send people up the garden path by either NOT detecting everthing or flagging codes at randem, I have seen some of the smaller garages have differant scanners from differant makers and try them all to see what other codes they can get, get it connected to Mercedes diagnostic for best checks.
