Hi all, got the attached random fault lights come on at the same time, any advice????BBD7154D-2D8C-455C-8A5E-0A615C4465CC.jpeg
 
I was told by my indie it might be low battery power as it's not been driven so I have a trickle charger on and I'll see if it clears tomorrow.

Maybe a sensor, as per link above.

The key difference is the OP does not have the tyre pressure warning light on which pretty much rules out the wheel speed sensors.

Need a code reader on it to be sure but likely to be the abs pressure sensors (easy, cheap fix) or brushes on ABS pump.
 
Ive had these lights ,it was a Abs sensor as suggested about £10 each and a 5 minute diy job.
 
Weirdly enough I had the same two lights come on yesterday and was going to ask the forum the possible causes but Z4mal beat me to it. Mine is intermittent in that if you turn the engine off it clears but seems to come back on again, at least it has done the one time.
Where is the ABS sensor located btw..

Open the bonnet, top left corner in front of the master cylinder - you’ll see two of them. Best to replace both sensors - they’re not expensive and it’s a quick job. Just remember to seal the brake fluid reservoir with some clingfilm to minimize the loss of brake fluid when you unscrew the sensors.

Thats the brake pressure sensors (which works with the ABS etc) the ABS sensors are also the wheel speed sensors.
Remove the wheel and you will find some wires and the brake hose from the inner wing to the wheel hub follow the wires and these are what you are looking for the connection is in a little box on the inner wing at the front and hidden a little bit more at the rear
Also there some pad wear sensor wires in this area as well.

The reason they fail is normally a rust swell on the rotor rings and this wipes the face off the sensor so fitting new ones without checking the rotor rings will have the problem return

People are being confusing with their terminology here. ABS sensors generally refer to the wheel speed sensors, the pressure sensors are on the brake master cylinder (deleted on N52 engine).

A wheel speed sensor fault will typically bring on the tps warning light along with the other two.

I am one of the confused i was refering to brake sensors in engine bay :thumbsup:
 
So the battery charge option didn’t solve the issue, turns out my battery is good. So looks like it’s the sensors ( any suggestions on suppliers and part numbers??) and the removal of the wheels to look into the sensors ( not a job for me). Also I do not have the ABS light on in my case and my DSC button in car does not work anymore if that makes sense to you all. Thanks for the advice, forum is as great as ever.

....you don’t have the tyre pressure warning light on so why do you want to check the abs sensors on the hubs?
 
I’m happy to look into investing into a code reader, any suggestions to an appropriate one?

Great thanks I’ll take a look I’ve also been recommended the Autophix 590 which is a little more so going to compare the two and place an order today. I’ll let you know how I get on. :cry: :thumbsup:

Do you mean the Autophix 5900? Currently on offer on Amazon for £67.99 which is good value. I'm not sure it offers a great deal more functionality than the Creator though.
