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.

Even in the short time they had they managed to get an indication of the problem - something to do with the exhaust gasses running richer on one side than the other, which is causing the engine sensors to mis-read the situation.
Leading evidence: 'Run richer' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Run richer' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

Hi, I've searched through the various threads, but not found anyone who's had the same symptoms as myself...
Tonight I put in £30's worth of BP 'Premium' petrol, and went for a drive. About 20 minutes in, whilst crusing at 70mph on the motorway, my engine warning light came on, there was about 10 seconds of me repeating "oh *****, oh *****" and then it went off again.
Now I could be a bit paranoid, but I thought it was idling roughly (I was feeling slightly shaken about at idle), but I could've been looking too hard for problems. I wound down the windows and it all sounded fine.
From the other threads I've read, most people had a problem with the light staying on. Could it just have been a blip, or should I go and get it checked out?
As ever, your advice is appreciated.
Mine stayed on and flashed - that's the worst case apparently - and sure enough the engine was wrecked. If it makes an amateurish attempt at flashing only a few times you're probably OK.
Cheers
Thanks all,
I took the car over to Hartech on Saturday. I only made it an hour before they closed, but they confirmed that there was a problem (cylinders 4 & 6 weren't firing properly).
It was an odd situation, at idle there was a problem, but when being pushed it was absolutely fine.
Even in the short time they had they managed to get an indication of the problem - something to do with the exhaust gasses running richer on one side than the other, which is causing the engine sensors to mis-read the situation.
Further investigation is required, but hopefully it'll not be too serious/expensive... especially as I've *just* gotten the car back.
Balls. The engine needs to come out. Compression on cylinder 4 is at about 50PSI, whereas it's about 250PSI on the others.
On the bright side, I'm at least on the Hartech maintenance plan, and I have got 3 months warranty on the engine from the company I bought it from (PCT). So hopefully I'll be able to get it resolved without too much expense.
Still, not a brilliant start to Porsche ownership :nooo:
