Yellow exclamation mark and yellow dsc

Post by dans6490 » Tue May 22, 2018 5:29 pm

Took the zed for MOT today and it passed with no advisories.

The only thing he mentioned was that he had to cable tie the brake wear sensor and brake line as it was rubbing on one of the struts.

Off I went happy until I’ve gone back out in the car and now got the dreaded yellow dsc and yellow explanation mark dash lights.

IT must be related to what the mot guy has done but does anyone have an idea of what? They’re shut now but I’m guessing it must be something fairly simple to rectify?

They came up on mine a few weeks ago. Someone on here recommended to disconnect battery for 20 mins then once reconnected, drive it 100 yards and all cleared

Thanks....will give this a try. Do you know if it affects driving at all whilst lit?

It didn't with mine. Try the battery disconnect first and see how you get on

Got exactly the same on my Z3 at the mo. I'm still not sure why, code came up as brake switch!! But not convinced.

Seems a bit of a coincidence but...

Codes are the surefire way but typically:

1) DSC + ABS = ABS pump.
2) DSC + handbrake (in yellow) = pressure sensor
3) DSC + ABS + handbrake (in red) = wheel speed sensor.
4) DSC + ABS + handbrake (in yellow) + tyre pressure = wheel speed sensor.
5) DSC + ABS + handbrake (in yellow) = steering angle sensor fault / ABS pump.
6) DSC permanently on = steering angle sensor calibration issue / yaw sensor / lat accel sensor.

There are other combinations of faulty sensors which can cause similar lights but the above are the common ones.

Thanks for the reply, it’s appreciated. So it would seem to be the pressure sensor. How easy is that to change?

You’d be taking a bit of a gamble to conclude that without reading codes but yes, easy to change. Do a search for ‘pressure sensor’.

Thanks, is it two of these?

Those are the ones. Anybody local to you can do a quick code scan first? There are other things that can bring on those two lights.

I love this car but I’ve never known such a temperamental thing in my life! I unplugged the battery last night and this morning......hey presto......the lights are out!

If it reappears I will get it scanned but for now at least all seems well??

The pressure sensors do start to fail like that. Most of the time just turning the engine off and back on extinguishes them but they always come back on sooner or later. Wouldn't worry about it though, just drive it.
