Id be checking for water ingress

that's alright mate no issue. All the info helps

Thanks for this ! Mine are still original as far as I know (2012)

N53 is 11-16cm below top of filler neck as I posted above

Here you go. No markings on n53 neck nor n63. Check the coolant level when the engine has cooled down.Adjust the coolant level to (A) approx. 110 mm to 160 mm below the top edge of thecoolant filler neck. Possibly use a tape measure. https://www.f10-forum.de/index.php?thread/3418-kühlwasserstand-prüfen-wie/&postID=47933&highlight=523i#post47933

INPA and ISTA/D running on a laptop is what I use. Free apart from faff time.

It does. Which is why when all four went off at the same time I assumed as I had not driven over a police stinger it must be spurious. The TPWS system is pants, it's very slow to react but on this occasion was correct. I have non RFT fitted too. NSR was proper flat. Car drives *amazing* now. Funny that, but it's also quite interesting to me how well it drove at cough cough speed with a flat tyre and 3 low tyres.

Embarrassingly I did have what I thought was a spurious low pressure warning a week ago. I dismissed it because it showed all four as dodgy. Couldn't possibly all four flat, right! Realise I'm sounding like a bit of a plonker at this stage haha. In my defense my car has the bog standard rotational warning system not the actual pressure one.

Today I found the car to be a little squishy and tramliney on the motorway but haven't driven it for a while. Pulled up at destination and noticed the NSR tyre looked a little... flat. Didn't even register on my electric pump . Got it to a garage and splashed out 50p on checking all the tyres which I admit have not looked at in ages and they all were very low Listen up kids and check those tyre pressures more often than err, I do.

Hi @535i Andrew yeah exact same wording. Let me know if you find it cheaper than 70 smackerooneys. I couldn't find anything wrong with the wiring and lost interest in fixing it tbh, though probably should because I too get smells from time to time

Xenon are completly different setup to the halogens

I'd be interested to know this too. Not least because hella or whoever make the halogen housings would have had a hard time baking a LED into plastic housing directly so there must be a way of removing it. Unless they glued it in, LOL.

Doubt the LED are as bright as xenon yet but it's definitely going that way. I've had led in my projector halogen housing for over two years and no problem with MOT. Beam pattern is fine. I do try to keep the lenses clean though in case they diffuse the light and dazzle anyone. Definitely a more usable light than the halogen bulbs (brighter or just whiter, dunno). Mine are a few years old too so perhaps the ones linked above are much better these days.

I'd play about with tyre pressures first. Try going nearer the fully loaded limit as well as softer. Mine rides ok but I do remember coming from an e46 (with a properly sorted suspension setup by moi) thinking wowza the f10 is a crashy lump of a thing. I've had it over 5 years at this stage, almost as long as the aforementioned e46.
