Hi there,

I just joined the forum looking for some advice regarding my V70r.
It’s a Japanese import phase 3 auto and I’ve had fuel pump issues, and now fitted a generic replacement from PFS Volvo parts. long story short I’m now suffering with a recurring P0422 fault code. I thought it was down to high fuel pressure but I’ve fitted a regulator so that shouldn’t be it now. The only thing that keeps it off for any length of time is driving flat out otherwise it comes on 10 miles after you clear it. I’ve checked for intake air leaks and exhaust leaks so am thinking it might actually be the cat or the rear 02 but I’m not sure and fed up with trying.

Can anyone recommend a Volvo Specialist that maybe able to help me, I’m in the Bedford area but am also regularly I’m Watford.
Many thanks
Simon
