Reduced engine power
Well I got the reduced engine power light this weekend and it coded out to be the HPFP. 2011 c4s 41,000 miles. Either just a fluke or it wasn't fixed on the 11's. Not sure of the build date maybe it was in 2010 and got the older pump? Where would I find the build date? I'll ask my pdealer next time I talk to them. But just a fuel pump and not an engine so should be up n running next week
