Original is definitely 7mm.

It's something very small, like 7 or 8mm Natalie, off the top of my head. Very easy to shear off, I know from experience.. I think it's the very thin metal, plus the difficulty of avoiding putting any bending force onto it while working semi-blind round the back of the drum there.

It wasn't clear to me from the original post whether the new battery was actually giving any trouble or not. Seemed more like the unexpected charging voltages were giving the OP the (false) impression that there was a residual problem.

All the best.

Yep, exactly that, I believe, because the airbox has no temperature control/warm-air feed unlike previous iterations on the 1.4/16V engines.

Good plan. Do it. 👍 Doubt you'd miss it if you left it like that hereafter.

Might be the actual front left (nearside) sensor, or possibly a broken wire or corroded connection in the loom plug, Worth checking wiring near connector, and visual impression of connector contacts before spending on a replacement sensor, if poss. The ABS code I would be suspicious of relating to the blade fuse that the thinner red/green wire is going to (25Amp one?) or damage to that wire between there and ABS module. Unplugging connector from ABS module, and measuring voltage at the relevant connection would be ideal. Will give pin number later.

Maybe you could just say what your impression of the video was?

What's your executive summary George, please? OK or not OK? Can't be listening to 16 minutes of that accent.

Sadly that variable charging voltage is exactly what you should expect from the alternator in a VW group car with start/stop, so you probably just scrapped a working alternator. The voltage varies to try to match supply and demand on the system. When the new battery was fitted, was the car's battery monitor module re-coded to 'know' about the change?

Ebay? Just search "BBZ engine".

Probably don't need to lift the car for the measurements I'm thinking of. 👍 I'll have a think and post more tomorrow.

I can't promise to fix everything, but I bet we could understand what needs doing pretty quickly. Might be as simple as a bad connection between alternator and battery. Or the engine earth connection being a bit corroded. Do you have a multimeter? Or know someone that could lend you one? Could maybe do some measurements that would tell a story.

Bring it over to me in Oxfordshire some time.

Yes, that second one is 110A, which covers the while interior and its fusebox. Power steering one next to it in position 3 should be 50A, then the last ones with the dodgy fuses should both be 40A. I would leave the one for the fans (thinner red/black wire) as-is, but change the right-most one with the red/green wire for a 'legit' 40A one. That's the ABS pump fuse. Clean contact surfaces before fitting new fuses, ideally.

Yes, the fusebox on the end of the dashboard. Good, the battery light should come on and then go off as the engine starts. There's a common wiring fault, especially on the diesels where there's more vibration, that results in charging problems due to the alternator excitation wire breaking. If the battery light comes on, it's fine.

Fuse 25 in the cabin fuseholder is the other one. Fingers crossed that it's all just down to the battery. Is it a diesel or petrol engine? Does the battery symbol light up when you switch ignition on, before starting to turn the engine over?

40 Amp for ABS strip fuse, there's also at least one other, probably that 25 Amp blade fuse from your first photo (also a red/green wire, from memory?). On a train just now so can't check for a third, but will do later.

ABS fault might be the bodgy fuse in position 6.

Yeah, good pics, but still can't really see if there's a crack there. May be worth getting a pack of assorted fuses from Halfords, which will include a 50A one which is correct for there, and hopefully a couple of 40A ones which would suit where the two ill-fitting ones have been put. Halfords Assorted OTO Strip Fuses 30>60 Amp (FUSE133) | Halfords UK Could use a 30A one for the fans which is position 5 on your fuse board. Looks like there's only one of each value in the Halfords variety pack. On second thoughts, leave the bodged ones as they are, if there's no problem, don't fix.

That's them. Looks like some previous bodgery at positions 5 and 6 with wrong-fitment fuses, but your power steering one looks to be in position 3 from left. See if you can get a sharper pic of just that one. I think I can see a hint of a line across it very near the middle of the necked bit.

These. I think power steering is the fifth one from left. Thicker of the two red/black wires goes to it.

No, the all-metal strips that the four or five thick wires connect to, nearer to engine on that fuse board. It's not obvious that they are fuses, at a glance.

Yes, and yes. Message me please.
