HPFP Issues

Assuming you're talking about the fuel pump (HPFP is not a commonly understood expression) yes, it is. Many dealers have replaced lots of them under warranty already.

yes, i'm referring to the high pressure fuel pump in the N54 engine. i've been trying to research about that in canada but not too much information. i was informed that it was only affecting the coupe but i know that's a load of crap. any improvement?

AFAIK, no.

For a while the dealers didn't even have stock of the replacement ones. I know a few people who just retrofitted 255lph wahlboro pumps.

HPFP and Coil Packs are supposedly the biggest issues with the 335, *knock on wood* haven't had either issue thus far... its been 3 years and about 40,000kms.

Sorry, and to answer your first question, I really don't think the climate has ALL the much to do with it... I think it has to do with fuel quality and proper care when referring to a HPFP.

Beating the piss out of the car when it is cold (more related to turbocharger care) or on less and 1/4 tank is never advisable on a FI car, especially one with a HPFP.

I had a Warlboro in my (boosted) Civic back in the day and that was the first thing that turbo guys will tell you. You could actually hear it weeze when the fuel was too low and my foot was too heavy lol
