Evening guys. Been told people here might be a able to help me.
I have a 3 series m sport coupe 320i 2008. Over the past couple of days whilst driving along the traction control keeps on kicking in. Doing this is making it almost impossible to drive including loss of power. After a while I got a new light shine up on the dash board showing low pressure in the tyres. I pulled over checked the tyres and these were fine. Only way to get home was to turn the traction control off.
Anyone got any ideas of what this might be???

Not very familiar with 320 but there should be a DSC button beside where you lock unlock doors. Hold it for more than 3 seconds.

You might wanna pull some information with a BMW tools such as ista inpa.

So I held down the disc button and turned the traction control off. This was the only way to really get the car rolling again. A couple of people have suggested the abs sensor on either the front or back might be faulty. Cheers for the help so far.

Yeah so most likely is a ABS sensor problem or the wheel bearing magnetic strips are worn. You might need a new wheel bearing. To find out which one ore more info you need to diagnose it with BMW tools.

I think you will find that the ABS sensor rings on the rear of the hubs are covered in rust or dirt. Take of the wheels and gain access to the rings and give them a touch up with some emery cloth to clean. Should find this will fix the prob. Dont grind or file the rings as you dont want to loose any of the sensor. Happens in sandy, salty, or even wet humid areas.

The 320i has different rear ABS sensors with reluctor rings around the drive shaft.
They can crack or bulge hitting the ABS sensor due to rust.
You can get new rings here.
