Slight problem...

[Dancoopers]

Hi guys, I have a mark one mini cooper S on a 04 plate,
Strangely my abs, traction controll, flat tyre and hand break warning lights have all decided to turn them selves on not sure why???
Has any one got any ideas on what has caused this or how to reset them all?
Any help will be greatly appreciated.... If any more info is needed to diagnose this please just ask.....

Have you had any form of impact or wheel alignment issue? Reason I ask is that I once banged a BMW against the kerb in snow. Went quite hard and upset the wheel alignment. The dashboard lit up like a Christmas Tree!

The garage had to realign everything as the car is constantly sensing whether the relative speeds of the wheels and the position of the steering wheel too.

I'm no expert, but that's all I can think of, other than some form of computer / sensor issue.

Process of elimination.

It can be a number of things.

Start by checking the easiest, tyre pressures. Make sure they are all correct then go through the reset process - start engine, hold down runfalt reset button for 5 seconds(until runflat indicator comes one), drive away as normal. Runflat light should go off after 5 or 6 seconds and so should all the other lights.

Now monitor the lights to see if they return. If they do it could mean faulty wheel sensor, which should have a fault code via OBD Scanner. Could also be faulty wheel bearing which won't have a fault code.

Mine was a front wheel bearing. Symptoms were lights coming on, reset, run fine for 5 mins, sometimes a week, then they'd come on again. No fault codes recorded. I also had the tell tale noise at high speed, rythmic drone type noise. Died down if you steered slightly to the right, got louder when straight, even louder when steering to the left. Was front passenger side in the end.

Hope this helps.

Hi mate, mine is making that noise when turning slightly right, I had it diagnosed via the odb port and a fault code was a wheel sensor...
So what work will I need doing? Just the wheel speed sensor it's self?
Sorry I'm slightly confused

It's basically abs traction controll and break pads lights are all on, it's had a knock and been replaced with BMW parts and had 4 wheel alignment done....
The mechanic said when it had a knock the sensor cable was stretched (maybe faulty) so he soldered it on securely I have asked him to get me a whole new sensor cable, does this sound a good place to start? Are the abs traction and break pad sensors all running on this cable? If so we have maybe found the problem.... .???
