Red clip crumbled away and pressing into one of the revealed holes with a little electrical screwdriver did it. All sorted.

Whats the trick to getting the plug off with the red clip?

Managed to make a good enough connection and get ourselves home. Will see about a new plug or just a spade connector.

I just broke down with this exact issue. Happy to wait for Green Flag to come and look at it until the wait went from 15 to 90 minutes, then I started stuffing the bare wire end in but so far to no avail 😭

5W30 it has that VW 505 code. It's never used much oil, sounds as sweet and is as nippy as ever.

Did the usual commute... No light so hopefully it was a dirty filter, which it certainly was.

Doing a change today. Is a thicker oil an option for higher mileage engines anyway? 120k on the clock. Are 'modern engines' picky about oil type?

Switch changed, not much improvement. Noticed light never comes on doing 65-70mph on A1 or main roads but does if revs drop below 2000 like taking a roundabout or side road. Blocked oil filter maybe time for a change, not sure when I did it TBH.

For what it costs, going to replace it. Lucas part.

Seems clean.

Initially came on pulling into the works car park. This was after driving through a village and prior to that, several miles of motorway. Got it again once more on way home stopping at a roundabout. Levels maybe 3/4 to1/2 so topped it up at home. Next day same again in the car park (there is a steep ramp 🤔) and a few times on the way home but not on motorway, just rural & suburban conditions. Loud bleeps, rapid flash and resets after say 30 seconds. Engine sweet at all times. Regular garages not available, thinking of chuck some parts at it.

Well, the car certainly likes those NGK ZFR6T-11G plugs. It also likes the middle plug not being hand tight with brown soot escaping anymore, judging by the coil on that cylinder (replaced). Will whip that one out again in the near future, clean the recess & plug seat for good measure but so far so happy.

101905617C comes up as what they gave me, NGK ZFR6T-11G according to various websites, so I guess I'll go with that.

I assume the car spares shop has incorrectly sold me some NGK ZFR6T-11G 5960 plugs which appear to be for the 1.4 according to the Haynes manual. The old ones that I changed previously and kept are ZFR5P-G. What my real question is, what effect does the gap have, in other words if it's 0.75mm instead of 0.8mm will it advance the timing and thus 'help' a high mileage engine? I notice the original plugs I took out a couple of years ago are more like 0.9mm gap.

I've put the old droplink back on until I can find Nylocs to replace the nuts that came with the new ones that keep coming undone, even with another nut on top. Not normal M8 threads that's for sure.
