If it's that simple I'll be pleasantly surprised, but slightly worried every time I fill up! Is crap fuel something that could cause an issue with these engines? |

Could you have put diesel in by mistake? |

Checked the receipt at the time as I was worried about that. Unleaded about £70 quid worth. Used about 15 miles of it before recovery. Apparently it's running just fine now. |

Garages have been known to have had bad petrol/contaminated with water or similar |

Apparently the wiring is fine. As far as I know the left bank is 1, 3, 5 and 7. AA chap swapped a couple of coil packs to the right hand bank to see if the fault followed thise coils, which it didn't. Voltage and resistance was fine to all coils as well. He forced a misfire on the right bank and IIRC the fault code showed that bank had even cylinder numbers.

The saga continues. Car been ok on short journeys but took it to the office yesterday and after 40 miles while idle waiting at a roundabout it started either misfiring or something that felt exactly the same. Juddering and bouncing revs. Gave it a rev, carried on and made it to the office with a bit more juddering. Made it home as well but was quite nervous it was gonna clap out again. No error messages this time, either!

Could always treat yourself to a GAP Diag. tool, worth there weight in gold anyway and carry it with you, then when it does it run your own diag. test and check for any fault codes. Would of thought there would be more logged faults though.

Funny you say that Col I was looking at them last night. Standard IID tool good enough or do I need to spend 5 times as much on the 'pro' version?

No the standard IID BT version is fine. Give Dan at Duckworth's a call I think they were doing special offer a short while ago, still around the £400.00 mark I think though.

IID BT every time, fantastic bit of kit to keep in the car, also worth looking at the for sale section on here and the Disco forum, along with group buys In Spain - 2018 F Pace - Frightened away from the Sports due to crank failures

with it you will be able to see Live values to notice which cylinder or bank is causing the problem before a fault code is logged.
