ABS and BRake yellow light
 

these two came on and no dsc working. car runs fine

remind me what it means pls

Wheel speed sensor ?
DSC unit ?
Aliens in Manhattan ?

Been through a big puddle?

no afaik

Probably as Alex says Shim. Wheel Speed Sensor.

I've had it a few times in my 325 going through puddles (we get a lot of 'em up north thi knowz). Things dry out and alls well again.

Faulty wheel speed sensor would possibly screw up gear changes in auto mode methinks - perraps the Giraffe/Gorilla/Monkey et al could confirm or correct this? Would also throw a code.

I messed with the adaptions on the 325 and the lights showed along with others and the car wouldn't start, I chose wrong engine ref in Inpa and everything went tits up. An ECU reset sorted it.

Simple brake pressure sensor 1 or 2 about 90£ each from bmw i did Craig's and yanto sensors 15min fix

Wot e sed :beer:

seems to have gone off today, will take her for a spin tomorrow and check

ta guys

It will come back on mate. Guaranteed. Mine teased for a while.

Sometimes it's not the sensor (despite diagnostics saying it is) but the plug and/or wiring attached to it.
Happened to mine few years ago and a tin of this stuff helped cured the problem. :thumbs:

Yep mine is also doing this. Waiting for it to become a bit more frequent before I address the issue.

Sensor
 

Dude,

Part No for brake pressure sensor 34521164458

peachy dood

Yanto knows first hand!!nothing better then experience!!

Mine came on after 6 months sleepsville, salmon relay replacement and no show so far. :thumbs:

mines come on now :banghead:l

Bit like Jimbo then !

mine this time was wheel speed sensors replaced by ELms whilst it was in for some other work and because the trip was looming

Had a WSS go a couple of years ago and all the lights on the right hand side came on and the DSC light,this time it's only the DSC and orange Brake light.Is this the same as you had Shim.

ABS and yellow brake light I think if the title is correct. Let me just check the bill to make sure I have it all right

Bill says "Replace both DSC sensors" B34.52.1.164.458

Ta ;)

DSC-ABS 005E20 trouble
 

Hi Guys, I just get the problem today. Both indicators in orange.

Here are my extract from Rheingold (I hope you are speaking French :)):

Any other options than change it ?

Hi again. I hope to not disturb regarding the many answers received :thumbs:

I still have the same trouble but now it is permanently.

I would like to order both captors 34 52 1 164 458 but I have an huge problem with access. So my question is for the ones who already changed these parts :
How can you acceed ????? It is extremely tight and I do not understand how to do to unscrew both captors. Thanks :beer:

The rear one is done with the ring end of the spanner, the front one with the open end of the spanner. A bit of patience and move the spanner around the brake pipes, it is possible:smokin:

Bit of cloth underneath to catch the brake fluid, and if you have something to wedge between the seat and the brake pedal, it creates a bit of a vacuum and stops loads of fluid coming out. The pedal needs to be pressed about 10cm at most.

Once loose, sqeeze your hand down between the partition and the brake pipes, unscrew and insert the new ones. I've got small hands so I find this job relatively easy :hahaha:

Then you will need to bleed the brakes, obviously!

Hope that helps:)

Thanks for your reply. I think I will wait for the reception of my 2 sensors ordered this morning and do both operation in the meantime with a specialist. I am not confident enough to do it by myself.

Not worth the risk with anything safety related:) Thnk its about a £500 repair to have both done at a UK main dealer, sensors are £98 each If I remember correctly.

It should be this price yes (around 140€). But I took the risk to order these ones :

OEM BMW, NEW, but without packaging.
Extreme cheap price. Top seller, very good critical.
Price just decreased on this reference. We will see.
I ordered 2. I will ask to my own garage to change the fluide and do the operation in the meantime.

If anyone ever needs a wheel speed sensor, the ATE one from Eurocarparts is just the BMW one with the BMW markings and part number rubbed off... For £50 cheaper.
