I don’t know if anyone can help but I’ve go a 2015 120D msport auto .I’ve had this car for about two years and love but just recently it’s been playing up. The problem I get is sometimes when pulling away at a junction, roundabout etc it hesitates and sometimes it does it going down the road but I get no warning lights on the dash. I’ve plugged in a fault code reader and the fault codes are- P255B(00), P255C(00),P284A(00) and P22AE. Any help much appreciated. Thanks in advance.

Morning Tim

Welcome to the Forum

You really need a BMW specific code reader to understand what is going on, the Generic codes you have are identifying symptoms. As you can see you have 4 codes any one could be causing the others as they are not seeing the correct operating parameters. The issue is you change a speed sensor (P255B) and find it hasn't cured the issue you can carry on changing parts till you cure the issue, an expensive.way of working

A BMW specific diagnostic will give accurate information as to whether your issue is Sensor related or Turbo related (which is what your codes indicate) I would either get a a copy of INSTA/INPA or BMW 1.4.0 or Carly for BMW easy and cheap to buy on the internet and load it onto a laptop or find a BMW specialist near you who can run a diagnostic for you (cost will be lower than a Main Dealer)

      Tyres..what's the best alternative to run flats

      Morning Jon The main reason I moved away from run flats with the X5 E70 was tyre choice, with my E53 X5 I had plenty of practice. I learned that the recommended Star marked tyres were (a) not necessarily easy to get (often on back order) (b) They were also very premium priced (as you know) I started using Bridgestone and Hankook and found that they were as well matched in a staggered set as the Star marked tyres so no transmission damage. I brought the E70 to cut the miles going onto the other X5 and quickly moved it onto Hankook non run flats a set of 4 285x40x20 Front and 315x35x20 rear was just under £800. In my breakdown kit I have as said a small compressor a can of tyre weld (or similar) and a tyre plug set. I have used it a couple of times a friend of my wife has a Volvo V60 on run flats she ran over a screw one of the plugs fixed it and stayed fixed until she needed tyres. My son inlaw suffered pot hole damage to his 330e when visiting us, a can of Tyre weld got him from Sussex back to the West Midlands where they live. When he went to the tyre shop they said "shouldn't use that stuff mate we cant repair tyres that have it in" well with 2 splits in the inner side wall it was a new tyre anyway but at least he could drive 190 miles and not be stuck overnight waiting for somewhere to open. If there is a puddle I slow right down or go around if I can because in sunny Sussex it will be a Pot Hole I would go with a repair/limp kit like mine and fingers crossed the roads on the continent are in better nick than ours As an aside our son inlaw started a claim against the county council it took ages to get a resolution they wanted to know how many miles the tyre had covered ? then how old was it then said as it was a used item they couldn't offer full value !!!! An invitation to appear on Rogue Traders finally got through Dave

      Clicking noise when disengaging the clutch,

      Clicking noise when disengaging clutch either when pulling off or changing gear, happens more in lower gears but can still happen in higher gears. if sat with engine running, in gear and handbrake on, and slowly release the clutch until it’s hitting point I will make the clicking noise aswell any ideas as to if this is serious or just a common bmw noise?

      Tyres..what's the best alternative to run flats

      Hi Dave, thanks for your fantastic reply. I'm on a staggered set and I recall the wheel shop retailer was concerned about the M40d brake calipers and the 19" space saver not fitting 21" wheel. Hmmm, been researching more, and people either love or hate RFTs, think I'm stuck with them until pcp runs out in Dec 2025, but I'm now nervous about long journeys abroad cos each time I have a sidewall blow out, there's no way to run the car for any distance without wrecking the rims...

      Tyres..what's the best alternative to run flats

      Hi Jon Welcome to the Forum First is your car fitted with a Square wheel set (same size rims front and rear) or a Staggered wheel set (Wider rear wheels than the front) I suspect your car will have a staggered set probably 8j Front and 9.5j rear, so fitting a space saver wheel/tyre will mean there will be a different rolling radius on one wheel which can cause damage to the Transfer case and or diffs quite quickly if driven on for any distance (probably why your Dealer was vague) Even if your car has a square set up if the rolling radius of one tyre is different damage can occur. It isn't just BMW who suffer from this many 4x4 cars have the same issue. First you would need to check the Off Set to make sure the 19" wheel clears your Brake callipers and fits in the boot along with a Jack and wheel brace. Then if you are sure it is only a real emergency measure and not a solution that will allow a distance to be covered and aware of the risks why not. I have 2 x X5;s both run 20" staggered wheels and early in their lives I changed run flats for standard tyres (as generally they are easier to source and wider choice, care still needs to be taken that front and rear Rolling Radius are closely matched) and I keep a small compressor and Tyre goo in the car in case (BMW actually supply these as well). I have used it twice and happy to say not on my car but to help out others. Hope this helps not confuses Dave
