Its weird - the D2 sensor was around for four years before the 4B C5 arrived but somehow has a 4B number despite only being used in a 4D chassis.

The C5 sensor (4B0907659A) turns up in 1998 and is fitted to everything until 2008 that isn't the D2, including the D3.

That is indeed very weird part numbering, especially with the A version following the B version by several years...

If only I could. This job has just gone to the bottom of the priority list.
I need to take 4 screws out, which also hold the ECU box lid down.
The middle 2 are fine but the outer one (by the pipes) has been damaged so a normal screwdriver will not grip.
And the inboard one just turns (not easily) without lifting so I suspect the metal insert it screws into is rotating in the plastic moulding.

It's much more important to keep my ECU box sealed and dry so I'm staying out of there for now.

Press once to engage and leave it on.
The system takes about 30 seconds to warm up from start before becoming active. When it activates by detecting pollution it has a time delay after going "clean" so won't constantly flip-flop between incoming air and recirculation.
Thanks I'll have a look for that when I go out in the car later today. Can't say I've ever noticed it, and yet I'm the sort of person (nerd) who will RTFM from front to back when I buy something new (although to be honest, I usually have a play first and then pick up the manual at the "I wonder what's that's for ..." point).

Is there a recommended method for dealing with these seized screws/bolts on the ECU cover?
For now I'm very tempted to just cut the trim so that I don't need to undo the recalcitrant screw, but in the longer run it ought to be undone and fixed "properly"

Are they just spinning? If so, force the lid open while turning the screw and it will pull the threaded insert out of the lower box. The trim will have to be forced out unfortunately. A bit of 3-in-1 / WD40 under the washer can help it come out without destroying it, as long as the screw isn't too tight. If they spin, it can probably be recovered.

Depending on how badly corroded the screws are, sometimes they can be loosened using mole grips on the insert once the lid is off. Worst case drill the heads off. I replace the factory inserts with M5 D nuts like these and fit new screws.

I did. I don't know how I missed that button in nearly 10 years of owning the car!

I guess I just saw the recirculate symbol and never really noticed the 'A'.

I tried it briefly last night (on a 1 hour round-trip to see Sandi Toksvig at The Lowry, which was rather funny and enjoyable I must say )

As I set off, I noticed the button wouldn't stay lit/active. It seems that this was because I was using the windscreen demister at the time. Once I turned that off, the auto-recirculate remained active for the whole journey. So I assume it's working as it should, even though there seems to be no indication that it's actually doing anything!

Excellent advice MJ, many thanks.
Found them on Screwfix, though these are M6 not M5 if that matters: https://www.screwfix.com/p/insert-nu...-50-pack/59937

M6 are too big - there isn't enough plastic in the box to hold them. There are plenty of M5 versions on ebay. I drill the original holes out to 8mm before fitting them. If you're replacing the screws I'd go for something 5mm longer than the originals as the threads are recessed in to the D nuts slightly. The original screws will just catch, except where the HVAC sensor is - you definitely need a longer one there.

Wonderful advice, many thanks. You've been there, done that and are an invaluable fount of knowledge.
