Hi all,

This car is my third F56 but the first time I’ve not had one brand new...

A few snagging issues I’d like fixed and thought it best to put in here so that anyone else now buying a 4-5 year old F56 with common issues can find advice in one place! Hopefully these are quite easy fixes?

  • Horn doesn’t work
  • Washer jets do not spread evenly - to the point the water doesn’t reach the top of the windscreen (have poked with a pin, didn’t help - can they be replaced easily?)
  • LED headlights get quite a lot of condensation - again due to having newer models I’ve never had this issue before
  • Bonnet catch very stiff, sometimes refuses to open without some real force on the lever
All in all though, done a few hundred miles in it now and LOVE the Cooper S. Wish I went for one years ago after a couple of Coopers. Oh well, I’m here now :)

Try some ptfe lube on the bonnet catches before any spending! Lots all over. Take the hose off the washer here and blow hard. Up through the nozzles and back through the nozzles! Worked for me on a different car.

The horn issue I'd be taking back to the dealing if you bought it from one as it's an MOT failure. Could simply be the switch behind the airbag. No SRS warning lights and other controls working ok would likely rule out the clock spring.
Washer jets does sound like trapped dirt in the nozzle. Jeremy's suggestion might do the trick. Could also try hot/boiling water run through the nozzles.
The lights are probably a sealing issue. Trouble will be finding where the moisture is getting in.
The bonnet catch, I've always used white lithium grease on all my cars. (Bonnet catches and the door/boot latches too) It has the benefit of remaining where it was applied for years as water doesn't displace it easily. Just have to be careful applying it as it gets everywhere (when applied using the aerosol) and is "fun" to remove.

The horn is a known issue. I had a new steering wheel to fix it over a year ago on my 2015 mini and now seems to be very temperamental again so I’m not sure it was fully fixed.

I had problems with my 66 plate MCS when I bought it. I had heard that the fix was a new steering wheel, but the local dealer fixed mine by cleaning the contacts inside.

Horn doesn’t work
Just for clarity: Are you referring to when the ignition is on?
Cuz it doesn't work when ignition is off...which is pretty stupid IMO. The other day, whilst parked with ignition off, this guy came too close while reversing and I pressed the horn and realised it doesn't work. Obviously, there isn't enough time in such situations to first switch on the car and then honk. end of rant

You might have to be quite accurate with the horn, i.e. hit it right on and not slightly from an angle?

I got my front fogs replaced under warranty for condensation, but you might be out of time for that....

My S bonnet catch was stupidly stiff. Needed a double pull, release then another pull...….

I had my 2015 F56 MCS serviced yesterday and have the exact same issue with the horn so I asked them to check it out. They quoted that it was poor contact and are going to try and find out how much it will cost me as BMW should contribute some towards the job due to it being a known issue. They quoted me around £450 for the job, with ~£390 of that being for the parts, and he said I will likely pay half of the part and the whole labour costs. Hope this helps!

A double pull is correct. First pull releases it onto a safety catch to prevent it from flying open if you are on the move. The second pull fully releases it. It's not like older cars where you pull the lever inside the car once then feel under the bonnet for the latch to open it.

If you've purchased it from a dealer, I'd imagine they've given you at least 12 months warranty? You'd be able to get atleast the horn and light condensation issue fixed I believe under that - the washer jets and bonnet latch, maybe not.

Thanks all. Not from a dealer, purchased privately (from a Premier League footballer!)

Will take to MINI for some quotes and also local BMW/MINI specialist.

The tyre monitoring sensors are doing my head in too - hopefully that’ll be fixed when I ditch the run flats!

Aware it’s a double pull to release the bonnets but sometimes it can take 6-7! The horn definitely doesn’t work properly, had to slam it on today for someone blindly pulling on to a roundabout, and it beeped like it would if you tapped it to grab your mates attention as you slowly drive down a High Street... Needs to be better!

There’s definitely no warranty on the car but I got a good deal so happy to spend the money to put these small issues right.

What are the tyre sensors doing/not doing, they should only give a warning when you lose an excessive amount of pressure. Every couple of months they may ask you to check the tyres and recalibrate the system but that's it.

They are failing to give a reading every time I start the car, but after a few miles will settle, and then at random fail again. When I perform a reset it gets to 49% and then gets stuck, never finishing.

That’ll be new sensor requirements then I assume? Have seen the figure £260 banded around for this ? Any chance new tyres and valves could fix it? Is it worth a try before sensor changes, or is it best to get them changed before new tyres go on?

The TPMS as fitted to BMW group cars is a PITA as far as I'm concerned. I know it's not as sophisticated, but the system fitted by VAG and others which (I think) operates via the ABS, uses standard valves, has no need for replaceable batteries and is so much more straightforward to live with. Perhaps though the simpler system is ok for non-runflat applications but not for runflat-equipped cars? Anyhoo, BMW's TPMS and runcrap tyres; what a brilliant combination they...aren't ?.

You never get a reading from them on start up you have to wait until the wheels have rotated for a minute or so.

I have seen a drop of 3-4psi just because of a drop in ambient air temp and after a few miles of driving or in warmer weather can see an increase of 1-2psi.

Have only had a warning after a pothole ripped a sidewall and the tyre was flat within 30 seconds, which I was glad to be made aware of.

Yes I understand this but on startup I’m getting a warning telling me i get the error fault. Then after driving off it sorts itself out. Then throughout the journey it will show the error messages at random again and again.

The valves have battery powered sensors in them-expected life is 5 year apparently so with a bit of luck new valves and the little sensor that goes with it will sort it-when I bought them from Mini for our winters they were £70 each but would expect there are plenty of alternative sources out there now? Your tyre fitter will know.
Plenty on ebay https://www.ebay.co.uk/itm/X4-TPMS-BMW-1-F20-2-F22-3-F30-4-F32-X1-F48-X2-F49-X5-F15-X6-F16-MINI-F54-F55-F56/153753596637?hash=item23cc6db2dd:g:OeYAAOSw-0Bd7Bqd or our dealer had the universal ones that they then programme to the car!
