+1 for the contitech belts Don't forget the AC belt as well

swap the new sensor into a different position and see if the fault follows

Vaico are highly rated

For those that may want to ditch the older CCC systems, and fit a double din unit in its place, there is this solution now: https://www.ebay.co.uk/itm/Black-Facia-Car-Stereo-Radio-Adaptor-Wiring-Fitting-Kit-for-BMW/184069980773?fits=Car+Make%3ABMW&hash=item2adb6d0265:g:udgAAOSwGsheO1Vt You do lose your screen and idrive controller, and no idea about the rest of the display infographics!

Unless you replace the headunit with a suitable android based unit, very unlikely. I don't think you can retrofit the NBT into an E6x, but even if you could it would be expensive.

Nope, that's an additional option on the seats, and requires further parts, switches and coding - same with active seats

Yeah, rub them down with wire wool or similar then wack on some grease

Probably the looms in the tailgate hinges. Once fixed the errors will go away without any resets needed. Sencom make the best replacements

I'd check the Battery Safety Terminal, as it sounds like it has gone open circuit hence triggering the airbag fault. You can buy a bypass kit and just remove the the connector to the battery and wiring in the bypass or just get a suitable resistor and do same.

I replaced mine with a pair of Bosch Aerotwins and never had the problems as described above ...

An optional extra I believe

It's to do with emissions, fuel quality and in some markets taxes.

if you type your vin number into a BMW decoder, it will give you the complete spec list

Well, I guess the TCU takes input from all sorts of stuff (even GPS on some cars!), so I guess the MAF may well be one of those.
