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 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.

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.

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

POST 2Original post

I had one of my variable cam actuators pack up a couple of years ago, felt lumpy on tickover , almost rocking, but seemed ok once on the move, but only had about 200 bhp , I think we changed both in the end. I’m sure it showed a code. 75PNO

POST 3 / ORIGINAL POSTEROriginal post

Thanks for the reply one of the codes was p1125

POST 4Original post

A faulty Variocam actuator normally gives P030* codes for one bank (either 301+302+303 or 304+305+306). It may also give an emissions code such as P1125 (on the same bank).

POST 5 / ORIGINAL POSTEROriginal post

Many thanks for the reply Richard as usual.Quick update number of faults says six. 50 cylinder 1 misfire emissions relevant, 51 same on cylinder 2 and three, 35 oxygen sensing range 1 cylinder 4-6 same 1-3. thank you all again

POST 6Original post

I had a variocam relay ou ton my 996.1 when I first bought it - fixing it definitely helped (£800 ish as I recall), but I'd check out the ICV as well.
