Suspected cause

I thought it was the GT3 wheels I had swapped to the car when I bought it, 18 x8 as opposed to 18 x 7.5 on fronts, but it turned out to be an PSM sensor which was not cheap,€495 +vat here in Ireland.

Suspected cause

I think it was the pedal switch that cured this particular fault (the MAF sensor was for a misfire problem) - which is good news for you as this part was considerably cheaper...

Outcome qualification: Negation, uncertainty or missing explicit repair resolution overrides the raw extraction signal.

Reported and suspected causes (3)

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.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 1 adjusted by outcome qualification.

1 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Have not had a chance to drive the car much recently but before Christmas i noticed that the above warning lights have come on, it only seams that this happens when i accelerate hard, as soon as i switch the engine off they go off, no problem again until i drive it hard, any ideas it may just be a sensor? Also recently had a break fluid change. Happy New Year to all club members. Phil

POST 2Original post

Had this on my C4 - fixed when I had MAF sensor changed and new brake pedal position switch. I think it was the pedal switch that cured this particular fault (the MAF sensor was for a misfire problem) - which is good news for you as this part was considerably cheaper... Although I doubt your local OPC will fit it free for you, like the dealer opposite the factory in Zuffenhausen did for me! [ ]

POST 3 / ORIGINAL POSTEROriginal post

Thanks for that Ian, i am sure it is straight forward enough has happened before in fact it has not come on for a year or so, may just leave it till i am next passing my opc. Phil

POST 4Original post

Hi Philippe I had a similar problem on my C4 last year. I thought it was the GT3 wheels I had swapped to the car when I bought it, 18 x8 as opposed to 18 x 7.5 on fronts, but it turned out to be an PSM sensor which was not cheap,€495 +vat here in Ireland. I got it fitted during a major service so do not have fitting cost. Hopefully it is the problem with the pedal switch! Regards Collie
