Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

I had the same problem and it turned out to be the MAF sensor.

Told them that with the PSE installation only being 2 weeks or so old I don't expect to pay a penny to repair the fault as I am holding them responsible.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I had the PSE installed to my MY2001 Carrera 4 a couple of weeks ago and whilst driving the car today the amber check engine light came on and has stayed on permanently. I have read the manual and this is the emission fault light. Could this be related to fitting the PSE? Advice greatly received as I am concerned about the health of my bank balance!!! Cheers Ollie

POST 2Original post

Take it to the dealer to find out what's wrong with it, they shouldn't charge too much ($50-100) for letting you know what's wrong with it. I had the same problem and it turned out to be the MAF sensor. How many miles? Mine went out at 28k.

POST 3Original post

Unless there was something wrong with the PSE install, CEL is usually the MAF sensor. Ocasionally, it can be a faulty cat.

POST 4Original post

My CEL went on right after a 30k mile service. First fault seemed odd, but the MAF was replaced (my expense). Came on again a few minutes later. Was reset twice. No luck. Ended up being a failed bellows tube. Cost on part was about $20, but the labor was huge - around $150.

POST 5Original post

Ollie, If your car is an '01, it still should be covered under the factory warranty. Just take it in and it should be repaired free of charge. Good luck.

POST 6Original post

I thought loose gas caps and O2 sensors were the most common CELs.

POST 7 / ORIGINAL POSTEROriginal post

Thanks guys, I have spoken to the dealer and they are looking at the car on Friday morning. Told them that with the PSE installation only being 2 weeks or so old I don't expect to pay a penny to repair the fault as I am holding them responsible. Got to be worth a try :-) Cheers Ollie
