As expected, (electric) EGR valve not looking pretty at all, and several chunks of carbon fell out before I got it off.

Just replace. Nothing to code.

502 00 is the VW Group spec that is correct for your engine. If you buy something that meets that spec, no other details need to be considered.

The FL is part of that number, stick it on the end and you'll have the real part number. I would suggest that your relevant PR codes must be 1JC and 0YF. Genuine spring of that PN is currently £111.50 + VAT at Skoda dealers.

Kind thought Mike, but I think I can live without.

Wet, I think; but I know precious little about DSGs.

Another DQ250, code PQS. 👍

Yes. I'd need VIN or reg plate number

Better. There was a stat in there, old below new. Oil and filter change tomorrow, if I get a chance. Fuel filter to follow once I've got a bit of diesel in a can to pre-fill it.

Partslink24 says that your VIN should have 5Q0937084AG, which has been superseded by 5Q0937084AJ Z00 I don't know enough to tell you anything more.

I didn't think mk3 Fabia had that functionality? Is this a mk4?

How?

£20 collected (Abingdon or Highworth), happy to post at cost to UK addresses. Not new, but works fine. No longer have partnering BT equipment so surplus to requirements. PM me if interested, ta. SOLD 19/09/24

What engine/fuel type?

It doesn't. Plenty grunty enough as is, and I doubt the EGR and TB have ever been cleaned out, so only going to get better. Found out why it was sold just now. Reviewing paperwork handed over to me. Audi recalled it for an airbag thing (69r7) a month or so back. That was free, but the upselling included a quote of £471 for rear discs and pads, cambelt for a shade under 1k, and cheekiest ever - 'rear washer nozzle inop. Req investigation' 1 hour labour at £216. 😁 Nozzle off (30 seconds) soak in descaler, refit. At least that was my approach.

I might get to it tomorrow afternoon, depending on how the morning goes. Genuinely curious to see. The sound insulation on the underside of the engine cover had done a nasty mix of falling off and disintegrating, covering the engine in black foam dust, now largely vacuumed away.

Beat the spinning engine cover nut by drilling and tapping an M3 thread in the stud, and sticking a screw in it to counterhold. Credit to workmate Richard for that idea.

Bloody engine top cover fixings are mostly busted. 🙁 One undid fine, one had pulled right through, third one has nut spinning. 😆

Unless I find that mine has been removed, it failed some time ago. Previous owner says he can't remember a time when it went above an indicated 70°C. He had the car for 12 years approx, but he is about my age, so his memory may not be 100% reliable.

FWIW this genuine one is made by Bremi, who made it in Germany according to other stamping on far end (also 'BTT'). The 1.186.87 B is what told me Bremi. I paid £33 delivered, including o-ring from an eBay seller. Does seem to work when dunked in boiling water.

06J 115 403Q £14.40 + VAT across a dealership parts counter. Google images of that confirm that it includes the male threaded part. So yes, yours has left that part behind in the engine upon removal.

Yeah, modest hassle to change stat so it's going to be genuine and tested in boiling water first, I reckon.

Thanks for the idea @mac11irl, but I believe VCDS has shown me enough evidence to reject the nice solution. Engine coolant temp and oil temp as read via engine ECU data are both very similar to what dash gauge is saying. I got a £184 quote for replacement of thermostat from the garage that gave it sn MOT on Thursday. When questioned, they told me this was for a pattern part too! So a genuine stat is arriving Monday via ebay and will be fitted by me in the next week or so. It should be a good opportunity to familiarise myself a bit with one side of the engine, and maybe give the alternator a look over while it's off.

Perhaps it doesn't have fronts?

Did they tell you it's the first time they have ever seen this problem? Skoda UK would almost certainly say that. Or the Skoda official dealerships would, or both.
