Bmw E46 318 M Sport Convertible.. Dsc Light On

[Waks786]

Hello people,
Bought my new Bmw last week but since then its developed a fault.
The dsc light came on and after doing some research i went and got wheel alignment done as it was out..
since then its gone off and come back on so ive cleaned all four sensors (the bit that goes into the disc brake etc..) I am no mechanic lol
After doing this ive been on a 20mile round trip on the motorway to reset the light but this has not happaned..

After doing further research i have turned the steering wheel from left to right a couple of times, turned the car off and noticed the light has then gone off...
After driving for a few miles the light has re-appeared...
Can you please advise me on what to do..

Many Thanks

I am in no way an expert or mechanic but maybe disconnecting the battery for a few minutes would reset the system - thats as much as i could do

Just make sure you have the radio code if it's not a BMW standard stereo.

Also are the tyre pressures ok? Mine were up to 10lbs down all round when i got my car. Are the tyres the same on each axle?

Good luck

Hi,
Saying that I did check the tyre presure and had the fronts changed to 35psi and rears to 32psi..
Is that correct? As i did read the rears are meant to be less then the fronts
They are 17 m sport alloys?

How do you disconnect the battery? Sorry im no mechanic lol and where will the radio code be if i have got one

Many Thanks

The recommended tyre pressure list should be on the drivers side door pillar under the lock. On mine, rears higher pressure than fronts but they are 18" rims and the pressures are in bar, 2.4 front and 2.9 rear on my list.

I understand the BMW stereos (E46) don't have radio codes, anything else might.

The battery is in the boot on the drivers side under the black plastic cover, i have a coupe not a convertible so i guess it's in the same place.

hi,
Thanks for helping..
Do the rears need to have more pressure then the fronts? as mine are the other way round..
I know where it the battery is located but need help disconnecting it. The car is fitted with the standard bmw cd headunit
Thanks

Is it just the DSC light that is on or are the ABS and Handbrake warning lights on as well?

Hi,
Sorry forgot to mention both Dsc light and Handbrake light are on and are showing Orange.

The DSC system has logged a fault. Get it read rather than just guessing.

It will most likely be a dodgy ABS sensor. If the speedo still works correctly when it happens then you can rule out the rear passenger side sensor.

Hi,
Yes the speedo works fine..
