Search J59 within the pdf to get to it quickly.The location in the relay panel is generally shown as a white number in a solid black rectangle, I seem to remember. Relay panel access requires lower dash trim removal, driver's side.

No faults logged in engine ECU. Reassuring, I guess; should have thought of that myself, but grateful for the suggestion. It did behave perfectly on both commutes today. I tried to recreate the slow-moving traffic queue by going the same way at the same time, but of course the traffic was flowing sweetly for once. 😆 Big test tomorrow, Bassenthwaite or bust... sounds a bit like a film title.

Good shout, thanks @SuperbTWM. I haven't, but will right now I think.

Looks like all RHD mk1s have TRW, the Koyo parts page only has a LHD system part number.

Have replied, requesting the missing characters.

All UK market ones are TRW, I believe, but I could double-check with VIN if you like.

Four different pins used in the ECU connector, according to this. Many pirated sources of ETKA info are online, just google "online ETKA" and choose one.

Which end is the problem, at the connector that goes onto the injector, or at the connector that goes onto the engine ECU?

Exhaust valves are more commonly found to be the problem on these engines.

115bhp I'll have you know. 😆 Not sure I'm brave enough to take it to high revs just now. Supposed to be driving to Bassenthwaite ( ~280 miles) with 3 passengers on Thursday. If it plays up again between now and then I think they'd better take their own vehicle.

Belt was done in 2020, but only 10 or 15k miles ago. Can't see it running as well as it did straight afterwards if there was a timing issue.

Knowledge and experience much appreciated @J.R..

Joined a very slow-moving queue at a roundabout just after leaving work. 'Engine' started making a nasty clatter each time I crept forward. Sounded nasty! Panicked a bit but thought, I'll see what happens when I get going again, if I make it round. It was good as gold. Even seemed a bit pokier than it has been recently. Scary minute or two and I'm a bit baffled as to what happened. Are those the circumstances when a DMF would clatter if everything was cold? Don't like that idea much. Prefer some dubious idea like some chunk of carbon loosened during EGR clean might have got involved with one intake port and caused a misfire in that cylinder? Any thoughts, pretty please?

Do a compression test. Don't be surprised if cylinder 1 shows low compression. 6-valve single cam or 12-valve twin cam 1.2?

Image of said 'wire of doom' with typical failure point arrowed: @LandK, as with rear door carrier leaks, this is one of those mk1 Fabia problem areas that's more of a 'when' than an 'if'.

Before you buy anything, have a good long look at the starter solenoid cable. These tend to fail gradually just where the wire comes out of the connector's strain relief. Insulation cracks then the copper strands gradually turn to dust with atmospheric access. May be that hitting the starter just jiggled this enough to temporarily make better contact.

Have a look at the belts by removing the top cover, but I doubt you'll see anything worrying. I wouldn't bother if I were you, those belts and associated bits will be good for a lot longer. Did the water pump get changed last time? Would you do the work yourself if you did change it? (Changes the economics of it greatly).

Less impressively, I hoovered ours for what felt like a very long time yesterday. It was filthy.

The connector is at/through the firewall, pretty much impossible to access cabin-side and a bunch of work to get to in scuttle on engine bay side.

Google to the rescue "skoda fabia abs wiring loom splice" found it, no sweat. Halfway down this page: ABS Warning light - Page 3 - Skoda Fabia Mk I (1999-2007) - BRISKODA

Another user a few years back (7!) discovered a splice in the (rear ABS) wiring somewhere under the rear door, which had corroded due to 'traditional' water ingress through carrier seals. Can't remember the username just now, but there are such splices here and there in the wiring looms, where wires are 'crimped' in with others and then taped over. More vulnerable than continuous insulated wires. I may remember as I wake up more through the day.

Lift up the rear seat squab, and you'll see it coming up and in there. From there I think it heads along the bottom of the door orifices, under the trim.
