535i Andrew

A 523i is a rare beastie, I think I've seen two! Get some pics up. Perhaps, but you don't look at the mantlepiece when you poke the fire though!

Just a thought but is it possible the previous owner molested it with a remap which could make it run hotter?

It could just be you have gone from a wallowy old barge to how it should be. What tyres are you running, crap or worn tyres can make handling fiddly or fidgety on these cars.

Yeah keep us updated please. A few of us have spotted rust on the rear anti roll bars but nothing like that on the front. What mileage is on your car? Oh and how remiss, welcome on here.

Is the car sitting down too low at the back end? Or is it at the correct level, you say it doesn't rise or fall. Do you hear the compressor run at other times? It could be an air leak in the springs, most likely culprit, you loose the spring effect and it gives a poor ride.

The labour to replace that shouldn't be much as it's quite accessible once the underbelly is off, it's only 4 bolts plus the links. Obviously much easier up on a ramp. https://www.newtis.info/tisv2/a/en/f10-535i-lim_201301/repair-manuals/31-front-axle-front-suspension/31-35-anti-roll-bar/1LK4quzy If it was my car I might investigate an upgrade to the standard bar as I find mine a bit too rolly polly at times when being enthusiastic in the bends.

As above front anti roll bar. But how did that happen? Pothole, corrosion or was it jacked up or towed by the anti roll bar. Roll bar comes complete with a set of bushes which weirdly aren't available separately. Good advice above replacing drop links (links between the roll bar and suspension) too they aren't expensive. If that has broken for whatever reason I would get the rest of the suspension checked out too.

I just fire up my compressor and use my impact wrench, that that has the same effect on the neighbours

Is the tailgate steel or aluminium? Let us know how you get on.

You have staggered rim set up which is common on F10s, 8.5" wide front rim with 245/40/19 tyres and 9" wide rear rim with 275/35/19 tyres. Do not change the rear tyre size wise to match the front as this won't fit as well on your 9" wide rear rims. It will alter the rolling radii of the wheel which may upset the systems that use the wheels sensors as inputs used to determine the cars speed. I had Michelin Primacy HP front tyres on mine when I bought it. They were original tyres to the car from 2013. They were a bit noisy as they were quite worn. I replaced with the more modern equivalent which is Michelin Primacy 3 rfts and it's been fine. I have these on all four rims and I'm happy with the performance I get from them. Tyre websites offer a noise rating as part of each tyres review. Sub 70dB is on the quieter end of the scale. You can then see what's best for your choices and budget. https://www.mytyres.co.uk/cgi-bin/rshop.pl?x_tyre_for=&tyre_for=&search_tool=&suchen=Search+for+tyres&dsco=110&m_s=3&s_p=&rsmFahrzeugart=ALL&Cookie=sea_rd_uk_Google_Search&with_bootstrap_flag=1&ist_hybris_orig=&cart_id=PvmtdcjwVE7L89d9.110.220887335&tabs=on&s_p_=&sowigan=So&Breite=275&Quer=35&S_Z=&Felge=19&Speed=&Load=&Marke=&kategorie=6&filter_preis_von=&filter_preis_bis=&RunFlat=1&homologation= Yes you are right, the suspension has been tailored to cope with rfts but plenty of owners who have changed to non rfts don't report any issues with the handling. No difference in tyre spec between SE and MSport models, only change is size due to different alloy rim sizes.

They won't like it as the cynic in me says they will only sell halve the amount of oil that they could! But then again they could have easily told me to bin it and buy more oil. They are in the business of selling oil to make money. Engines are usually developed in conjunction with an oil manufacturer to allow longer service intervals. And of course they will no doubt have paid BMW very well to allow BMW to write on every oil filler cap "BMW recommends Castrol".

^The man is spot on. Under the sub heading of Instrument Cluster. https://www.newtis.info/tisv2/a/en/f10-535i-lim_201301/wiring-functional-info/body/mirrors/exterior-mirrors/XkefPAL But that doesn't explain this. I had dampness on my mirrors at the weekend (when outside temp was above 3 deg C) and I switched on my heated rear screen which then demisted the mirrors, suggesting there is an alternative to active the mirror heating when the temp is above 3 deg C. Can't see anything so far in TIS that confirms this though. I can't find in TIS for my car the wording Matthew has found (presumably for his old F11) relating to wipers or position of the driving experience switch. Unless there is a subtle difference in high and low spec models as TIS outlines there is a difference in the way the signals are detected via the junction box electronics (JBE) on low spec or via the footwell module (FRM) on high spec models. I would imagine the difference in high and low spec would be full and part electric seats.

This has come up a few times on here before but I thought I would share this. I bought a couple of 4L containers of Castrol Edge Titanium FST 0W-30 (LL04) back in January 2016 to do an oil change on my E60. E60 got sold in Feb 2016 before I could do the oil change and the oil has sat in my garage sealed in its containers since. I contacted Castrol's tech dept. to see what they would advise on it being used in my car as an interim oil change in the next month or so. I told them how the oil was stored and that it has a fill date of 28/01/15, so it was already a year old when I bought it. This is their response. Hello Andrew, It sounds like you have stored your oil under good condition. I would recommend shaking the containers and pouring a little bit out. If the fluid is clear and bright, then it should be fine, but if there is any haze or particles, I would suggest purchasing fresh oil. If the oil were older than 5 years, I would recommend any purchasing fresh oil. Whilst the oil that you have is the correct oil for your car, if you do need to purchase fresh oil, due to changes in BMW requirements, we would now recommend Castrol EDGE 5W-30 M as the BMW LL04 approved oil. So there you go, from the manufacturer themselves with a caveat that I check it before hand and with a recommendation for a correct spec oil too.

No fairly sure mine had no decals on it at all. I'll need to find it now. I was watching the John Cleese film Clockwise last night (made in 1985, released in 1986) . It was full of 'retro' Fords. Mark IV and V Cortina's. Mark I and II Granada's. A Fiesta but not sure if Mk I or MkII and an early Orion and Sierra. Great memory trip to see all the old cars that have now been turned into washing machines. There was also a Morris 1100, a Maestro and a couple of Rover SD1 police cars too for fans of BLMC persuasion.

Mine only come on when I switch on the heated rear screen.
