Radiator (a recent Behr one) £25 PAS cooler 'loop' £15 Body control module GM5 £10 Passenger tail light £whatever AC condenser £10 These are all from a 1997 528iA. Collection only for big stuff. Sheffield S12.

Petrol, diesel, engine, year? Probably the fuel pump relay but the position varies according to what car it is. Normally a pale blue relay on the fuse board to the left of the pump fuse.

BMW designed it to have a viscous fan for the engine and an electric fan for the AC. If they could get away with having just one - 320d manual for example - then they would have done. The E46 320d auto has both fans as the auto gearbox oil cooler needs just that bit of extra cooling.

That's a nail hit firmly on the head. E39's are a bit too 'needy' to run on a shoestring and if you don't nip every minor thing in the bud they just turn into heaps. Very few owners ever did, just getting rid instead. Before you know it they just need everything doing and it's one problem after another.

Just replace the hose - it's ready for a new one!

Any E39 that has had 17 or more UK winters WILL be rusty. Even 'good' ones will have something starting in the rear sills and so on. A 'good' one from 2002 is in a mate's bodyshop after having the fuel tank dropped to rebuild the inner sills, all four jacking points and a full set of rusty fuel and brake pipes. It's a £2000 bill with the rear arches because the 'very slight' rusting on the rear aches turned out to be a bit more than that once bare metalled. Jap imports are the way to go. They are more money but you aren't welding it back together. I had a 1993 E36 325i Coupe in 2007 and it was absolutely mint underneath - you could wipe the dust of it underneath as opposed to some Titanic style nightmare.

So it's a 525i?

PM'd.

Input shaft rusted/seized into the spigot bearing? I can see a 17mm bell housing bolt still fitted as well. I may well be that the release bearing has seized and chewed into the pressure plate - that's caused by a clutch hose that is blocked and acting as a one way valve.

No idea but a Z3 1.9 one will. I have one and it's £30.

£45 posted - how long it will last is anyone's guess. They're a bit unpredictable. This one worked OK and they need coding to the car. Easy to change though - four Torx for the tunnel brace under the car, pull the exhaust heat shield back and you'll see the two 8mm bolts that secure the sensor and bracket to the tunnel. Then two plug connectors and a 22mm for the sensor probe into the rear exhaust. A slightly fiddly job. The N43 engine isn't BMW's best and they have a terrible reputation that is richly deserved. If it's not the NoX sensor it's the injectors, or the timing chain guides, or a low oil pressure warning because the oil pump is tired or the balance shaft bearings are worn out or the oil pressure solenoid is faulty. Apart from that they're OK.

I've just found a NoX sensor in a box of bits. It cane from a 120i I had the engine out of.
