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.

Discussions that contain suggestions: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suggestion
I had it on my 996T, and running a diagnostic check gave a fault code for the MAF sensor.

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

Help!! Im having a nightmare in the middle of France! Intermittent PSM / ABS failure warning lights coming on & now engine cutting out at low revs eg as I approach traffic lights. Car has just had major service plus other stuff eg ignition coils at No.5 Porsche in London who are normally very good. They‘ve put me in touch with an indie in Reims so I’m taking it there. But if anyone else has had this it’d be useful to know what the cause was. thank

POST 2Original post

Does the PSM/ABS message come on when you accelerate quickly? If so, it might be a MAF sensor failure. I had it on my 996T, and running a diagnostic check gave a fault code for the MAF sensor.

POST 3 / ORIGINAL POSTEROriginal post

Thank you. At garage in Reims. They think it’s MAF too. Fingers crossed!!!

POST 4 / ORIGINAL POSTEROriginal post

Damn! Not the MAF. Any other ideas? French guys think it’s something to do with air intake?

POST 5Original post

Sorry for the late reply...... What fault codes are recorded?

POST 6 / ORIGINAL POSTEROriginal post

It’s been fixed by these guys https://www.easycarsreims.com/ who are brilliant!!! The near side turbo air intake hose had not been clamped into place and had worked its way loose & eventually come off. This explains why I was able to drive no problem from London to south of Calais before getting PSM/ABS messages & misfire / stalling. They tried to explain it to me but my French is limited but it has something to do with compression when I braked. Looks like the hose wasn’t clamped in place at all. They took before & after photos to show no clamp on the hose. At least its fixed and I’m back on the road. But I’ll be seeking answers when I get back to UK....
