Engine Service Soon Light

HighM5 · 11th July 2002, 06:45

The Light from Hell went on and the dealer diagnosed a loose gas cap. It was replaced. Light stayed off for 1 week, came back on. I brought it in for an OBD-II diagnosis........unclear..but thinks it is "probably" a fuel line vent issue.

Ordered up a new part today and I'll let you know what the outcome will be on July 30th.

Anyone been down this road??

Good luck to you, I am sure it will be alright.
Which one is the fastest the Nissan or the M5 ? More importantly which one is the most fun to drive

Don't worry about this one, lots of people had the faulty fuel pressure pump. There is a pump which pressurizes the fuel tank in order to determine if there is a leak, that's why it throws a fault when the cap is loose. They are notorious for failure.

The first time the problem was diagnosed they suspected it was a loose gas cap so they just reset it and told me to make sure it clicked 3 times.

It might be the mass air flow meters. My fault code came back as a catalytic converter problem but there was a service bulletin out to change all the MAFs first then see if the problem persisted. 2 weeks later, still no more SES.

I had the exact same situation, since replacing the part last week I've had no more problems.
