Both of mine had DSC (2002 184 manual, and 2003 204 manual). Are you sure it's defo got ASC, and not just had the button replaced with the wrong one? Neither had tyre pressure checking either A check of the VIN should reveal all... https://decoder.bvzine.com/

My spreadsheet said I got £100 for mine(!), with an aux cable included. It had been modified for pre-amp RCA outputs though, but I don't think the guy bought it for that. Near-perfect cosmetically too - no scuffs/marks or nicks to the volume knob

Changed the front disks/pads/calipers (after I rebuilt a spare set). Put the jack through the sill that had rusted out. I'll add that to the list of repairs needed then!

I think it was 5w30, maybe. Mine's a 330d though, so not comparable

I shop around - ECP (but they're getting worse with their constant sales), eBay (for branded stuff, not the cheap/unknown makes), and HotUKDeals (I got 7l of Castrol oil for £10 through Tesco thanks to HUKD and a mistake by Tesco).

I believe it's a 184/204 thing. My 184 didn't show boost/MAF/data etc. in Torque, but my 204 does. I've heard others with the same situation. (Or I've totally misread your post, in which case, ignore me!)

FWWI, there's a lot of cheap ones on the various E46 facebook groups. They could well be cheap for a reason, but it might be worth a look? Mine is in for arches (with a friend) at the moment. What started off as some bubbling has turned into basically all of the inner arch being replaced. I'd dread to think of the labour costs for making and welding in new panels. Fun times(!) I found mine needed work just by poking the inside by hand, and it crumbled. If it's soft under there, walk away.

I'd be interested in knowing this too!

You can unplug the vacuum line to that flap which should then leave it open all the time (assuming it hasn't seized, in which case, it might need hammering open). It's worth trying before spending any £££!

I replaced my water pump a couple of weeks ago. I used the metal gasket, as well as some liquid gasket stuff on both sides as well - no leaks at all that I've noticed yet, after a few tanks of fuel. I can't remember which one (and the tube is covered in the stuff, so I can't read it, but something like this: http://www.loctite.co.uk/gasketing-9224.htm#a) That stuff does dry/sets, and is forming the sole gasket between the diff case and the diff itself on my e30. (Short term fix that proved stable long term, so I left it for fear of inducing another leak.)

My front xenon arm snapped (well, the ball & socket joint failed), there's no way such a tiny part would make a noise audible within the cabin. Not any of the ball joints on the wishbones is it?

I've got the Zlines on one axle on mine (can't remember which), and really like them. Their winter tyres were very impressive too, until they went bald.

I reused them on my last e46. Lasted *0,000 miles with no problem.

Bulbs blown then?

The LCM is only worth investigating at this point if there's no 12v making it to the headlight connector. (This is the first test I'd be doing - it's free, and easy.) It's the control unit for all the lights, and can be set to tell the car it's a saloon, touring, coupe, with/without xenons etc. If you've got 12v, then you can likely ignore it for now. If, once you've got new bulbs, and you find it flickers badly, then the LCM will be worth looking at. (Usually what happens when you fit xenons, and don't tell the car.) The ballast/ignitors are separate - and can be found in the engine bay, under the lights. The LCM is the right hand thing in the image below. Wrong
