Thanks is advance! Remove Advertisements. I didn't even have to take it apart or remove it at all. The sensor is basically a potentiometer like how the old radios uses it for the volume control. If you had one that was dirty you would hear static when you adjust the volume. So basically that is what the sensor is doing too.

The poteniometer gets oxidize and you will get a fault when the computer doesn't read the resistance from the sensor. You should be able to clean it and may not even need to reprogram it. I sprayed it on the outside and around the sensor and turn the steering to work in the liquid.

You can go to ebay to get the spray. If you need the tool to recalibrate the SAS. It is useful to have the tool because you can watch the live data on the sensor while you turn the steering. You can see that the sesnor skips the resistance reading.

I got mine also on ebay. Picture of Deoxit and the sensor where I sprayed it on the outside.Original Poster.

Have just turned into my road and the car beeped at me and is now showing the DSC and brake warning light in amber. The manual doesn't say a fat lot and Google will be my next call but would also appreciate any advice on what it could be?

Didn't do the diy myself. Worth noting afaik your dsc and dtc won't be working while the lights are on. Someone with more knowledge than me will add to this, I'm sure. Fox- 13, posts months.

It could be an absolute myriad of different things - some requiring a simple reset of the fault codes, some requiring a replacement DSC hydro unit. Without looking at the codes its pretty hard to say. Totally get what you're saying Fox, it's like a needle in a haystack without a fault code.

TheEnd 15, posts months. I'll take a guess at 5E20 pressure sensor 1. There are two screwed into the master cyl on E46s, both the same but an inch or so apart. Is the steering straight? I ask because my e46 gave same warning lamps when a failed rear trailing arm bush cocked the steering.

I've done a fair bit of research into this recently. There are also a few recent threads regarding the same issue within the M Power forum. Pressure sensors failed. DSC unit failure.

I got the codes read and it turned out to be steering wheel sensor that threw up the error.

Didn't see it again for about 18 months, then it came on again. Turned off the engine, and turned it on again and haven't seen in in nearly 6 months.

Sometimes sensors just throw up anomalous errors - i would monitor it for a while and if it doesn't come back on - put it down to a anomalous reading. There's no point going balls out and paying hundreds of pounds to a dealer if it was just a sensor error.

But the problem is how does the OP know if it's a dicky sensor or not? If you're on friendly terms with your dealer, they may read the codes for free.Braking is applied to individual wheels depending on which direction the car is off course.

If the vehicle starts to travel in a path that does not match the direction or angle of your steering wheel, then the DSC will quickly apply the appropriate wheel brakes to recover and put you back on a straight line. It detects what direction angle you are pointing the steering wheel and feeds that information to the DSC.

If so, confirm the noise is not from the clock spring, if not the issue is likely the column. The steering angle sensor is mounted to the base of the steering shaft, near the firewall. The column has to be removed to replace this sensor. Once replaced, the sensor will have to be adapted using an advanced BMW scan tool.
