Can you not read the part number off the existing sensor?

I would think that's very doubtful. VW group tend to fit looms with only the required functionality per vehicle. Hope I'm wrong for your sake.

Perfect.

So not really, really loud and frantic-sounding then either?

As long as the fan didn't sound really really loud and furious when it did come on; which might indicate that it went straight to full speed?

Sounds like about the right price for the DSG stat.

From memory, the low speed fan function triggers at about 95°C at the radiator thermoswitch. Are you wanting to check the fan function, or just get it up to full temp to be sure everything is flowing as it should following the stat swap? To check low speed fan function, unplug the radiator thermoswitch connector and short the pins on the loom connector that the blue/brown and brown wires go to.

Which engine type?

Yep. Are you changing the relay, or the whole unit?

Indeed, also mentioned in that link above; Skoda refer to it as "Control system for exhaust gases" Screenshot from a mk2 Fabia Owners Manual:

Electronic Power Control, I think. And MIL is Malfunction Indicator Lamp. EPC is spelled out in capital letters on cars with that warning light. Here's a post with an extract from an owners manual: https://www.briskoda.net/forums/topic/150495-epc-warning-light/?do=findComment&comment=1874575

You might find it's got a failed low-speed function, so worth checking that out. Very common failure, I believe.

Could be a very long time, especially if your car has a diesel engine; much better to go out for a drive, preferably a lively one, then leave the car idling afterwards to observe such fan action. Take a litre or so of top-up coolant with you in case the level drops enough to trigger the low level alarm whilst on the road.

You're possibly better off asking for help in the appropriate subforum on here, to be honest. The official manuals are not that nicely written, although they do cover absolutely everything, but in many different documents. I wouldn't have a clue where to start to look for answers to your 'for example' issue above, but someone on here probably will have some good suggestions, and may even have had and solved that exact problem.

Just use the workshop manuals.com site then; same info, just without working hyperlinks etc. and with a generous supply of pop-ups. Why would you need to keep returning to erWin if you've downloaded the pdfs?

Offical Skoda manuals site? - Handy Topics & Guides - BRISKODA

Not at all. It is copied directly from info on official sources such as erWin Skoda though, within which a small fee for an hour's access unlocks a vast database of downloadable pdfs if you go via the individual vehicle information tab.

I should think it was probably just a typing error on the invoice? How much was this part? If you're a very lucky person, it may have been installed with the part number facing in a direction where it can be seen unobstructed by too much other stuff..

So my engine isn't lean burn after all? Let's see what the OP finds out, and perhaps Stewart, rather than blether on irrelevantly about other stuff.

I was just pointing out the oddness of sepulchrave's comment about 'lean burn' engine in my car.

stoichiometry - Google Search

Both run at stoic due to lambda control and cat(s).

Have you looked at the sensor output on yours with VCDS or similar Stewart, to see what temperature it runs at? I wouldn't be at all happy if my engine ran at 80C.

Apart from making it more difficult to remove the panels that leak by changing the fasteners from screws to rivets in 2004!

Thanks for adding to this @xyzal. Shortening and refitting with heat may work if the hose is long enough. On the BBY-code engine in my Polo it isn't, sadly. I've temporarily patched it with self-amalgamating tape and a couple of tyraps, but it will have to be changed again at some point I think.
