R56 DSC & Run Flat Failure. HELP.

Hey,

I have read about this issue on this forum and others, but I'm yet to find a final verdict.

Months ago some warning lights come up on my dash (photos attached) for a few moments and went. Over time these lights have been coming on more and more until now they're almost always on; so I guess it's time I did something about it.

I've always used my ears and senses to feel if there are issues with my car, rather than pamper to all the fault lights the R56 likes to throw at me.

The car does genuinely feel fine, although it does 100% need some new tyres...

I looked through my manual and it says I have a 'DSC & Run Flat Failure' (photo attached). I have highlighted the section on my image where the lights match with the manual.

Has anyone seen this issue before and know how to fix it? Me and my dad do all the work ourselves usually (depending on lab costs), so I wanted to know if it's simple or a technical job. I didn't know wether it was something to do with my tyres (hoping it's something simple)!?

Thanks!!!

The red light is telling you to check your brake pads. There is a sensor on the front and rear that switches the light on when they get low.

Hook the car up to an obd reader and see what sensor has been triggered and take it from there buddy

I'm not sure it's that. I changed all the pads and sensors in June. Plus, when I flick through the computer it says the pads are fine, so I don't think it's triggered those sensors.

Have you read the codes to see if anything has been stored on the ecu? When I'm diagnosing problems I usually hook one of my obd readers on it if I'm unsure then take it from there. The car may tell you it has a fault with a system but it doesn't always mean that the system displaying a fault is actually faulty so you need to trace it back and see what has caused the sensor to be triggered!

Right so, I think I've solved the issue (he says)... for all of you out there that are having the same issues, this is what I did.

I read on another forum that it could either be the wheel speed sensor or the steering angle sensor.

I called up my local BMW specialist and they told me it would be 70 for the diagnostic test and if it was the steering angle sensor, then the column would need replacing which would be 400 + 500 lab. I obviously laughed and put the phone down.

I first tried the simple fix of cleaning the wheel speed sensors as I read these get very dirty and is a common fault on the 1st and 2nd gen minis. I followed this link to find where the part was (Pelican Technical Article: ABS Wheel Speed Sensor Testing R56). I only cleaned the piece that reads the wheel speed, I didn't bother with the connector. I used some meths and numerous drill bits to clean the plastic bit that goes in behind the wheel hub and hole itself. I used some silicone based grease to make sure dirt wouldn't get in as easy (I read that on a forum as well). I took the car for a spin and the lights were still there... AAAGGGHHHH!!!

I pulled back on the drive and decided to have a mess with the dash to see if I could sort anything AND I got the codes up!!!!! Now I'm not 100% sure how I did this but I followed this youtube video (Resetting brake pad service indicator R56 MINI Cooper S). Instead of going into the service section as he does on the video, I pressed and held the stalk on the "CHECK INFO" section. It the gave me the two fault lights in the middle of the screen and nothing else. I decided to press and hold the stalk on one of the lights for a good while and it jumped back to the home section. BUT as it jumped back to the home section, some codes appeared for a fraction of a second on the screen. I then repeated the process and the codes were there with the light (SEE MY IMAGES ATTACHED)!!!! As you can see from the images I had code CC-ID 074 & CC-ID 237.

I then googled these codes and CC-ID 074 meant I had low brake fluid and 237 meant there was a stability error. I then topped the brake fluid up but it was basically overflowing anyway, so I just wiggled about the box. I rang my local BMW dealer again and asked them if they knew what the 237 fault could be and they didn't want to know! They said the only way they would ask a mechanic would be if I were to bring it in and them to see the codes for themselves (what a joke).

I decided to give the car a little wiz after messing with the brake fluid pot and THE LIGHTS HAD GONE! I can't say for definite that they're gone for good and I don't know if it was actually the wheel speed sensors that did it and they needed time to reset but either way, I think I did it. I wont know until I give it a good drive but I'm currently buzzing!!

I hope that makes sense to anyone that has these lights and unfortunately has an R56, because it's by far the most stressful car EVER! I can't wait to sell and get a Japanese!
