Paint on the mating face is only likely to be an issue from preventing the wheel seating properly. If there really is a paint of 2mm thick that can insulate enough to keep heat in to warp a disc please let me know the make - I'll insulate my roof with it

F10 n53 here and agree that low 20's around town should be easy but I'd also say that I regularly see 14-15mpg if I do ridiculously short trips often, like 1 mile drive stop for a while then drive back so the engine is stone cold, like when I pick the kids up. OTOH I just got 39.2mpg on a very fast run from cardiff to Heathrow. Average speed was very close to 70mph. What's your MPG like on a decent run? NOx sensor will affect MPG big time but presumably you see no codes for that?

I had my rear wheel liner out to do the spring (unnecessarily) and it wasn't too bad a job to get out. Bitch getting back in mind. I was surprised how much crud and cobwebs were behind it! Worth doing every now and then I think, as in every few years if the car is a keeper (does anyone keep cars these days?)

+n53 in f10/F11 as 523i, 528I, 530i

What's with all the smoke?

Did you go for RFT in the end?

Did you replace the rear prop coupling yourself OP or get a garage to do it?

Very poor. There are no mechanics in dealers these days just fitters fitting new parts. What on earth made them think they could repair a loom?

There is something very sexy about seeing foam running across the f10 currrves especially carbon black Edit loving thy ps91's and working rear springs. Like a new car. So glad to be RFT free finally, am all clear.

Yup that's what I do

It's got to help giving the dirt a good soaking surely?

Finally replaced the RFT for khumo ps91 (275 40 18) on the back, was going to get MPSS but as I'm still not sure if I'm changing cars (I'm such a pro procrastinator) or maybe just get 19's thought I'd try the khumo out. Also got to have a good look underneath as my mate did the MOT. Looks great underneath all tidy and nothing significant. Initially couldn't get it through emissions as lambda was 2.6 but the MOT machine was not picking up the right engine for some reason.

Amazing what you can do with tippex and a steady hand ? Edit I just realised it's the white bit that's wrong. Don't think I've ever looked that closely at mine before. Black pen?

I thought that too, but I think it's full black panel in different modes, so same top and bottom

Afaik there is one high pressure sensor and one low pressure sensor. I've heard of these failing but not the manifold one. Check out bimmerprofs website. Also realoem shows the fuel layout but you know that already I'm sure. Yeah get indy to confirm! LP fuel pressure sensors is under the manifold, HP is at the end of the rail.
