Read evidence and context

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 performed work without a confirmed outcome: 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.

Suspected cause
I'm not going to be very helpful but had similar fault in previous car and it turned out to be a faulty sensor which was sending 'fault' meassage to management system and telling it to limit the revs to protect the engine - seem to recall it was cheap fix - so you need to get it plug into computer to see what's going on.

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.

POST 1 / ORIGINAL POSTEROriginal post

Hello guys, My car is a 996 c4 manual year 99 with new factory engine fitted in 2007. All seems well and drives great , but on a couple of occasions after about 30 mins of driving have experienced complete power loss, engine dies down to tickover as if someone has cut fuel . Looking in history this has happened before and OPC changed the DME module and air mass sensor . Obviously this was not the problem . If I restart the engine all is fine again no warning lights etc . Do you think it may be the DME relay playing up . Power etc all seems good , anyone else had anything similar Touring50

POST 2Original post

Won't be the DME relay: if that is faulty you would get no fuel at all: the engine would completely cut out AFAIK.

Thanx for the replies, it is going into PCT Coventry Monday for a service hopefully will be able to sort out, did you know which sensor was faulty :?:

This is a source reference. Confirm exact model applicability in the original material.
