ETS+ABS warning light problem

[discoking]

Hello,I hoping you can help me with a problem I have on my W140 S320 '97 model.The ABS+ETS warning lights come on randomly and I loose power steering at the same time.

Normally if I stop the car and restart her the lights go out normally and theres no problem untill they come on again,which can be after 5mins,2 hrs or sometimes a couple of days.

I'm hoping to get some advice as to what it may be so I can go to the relevant mechanic/auto electrician or even the merc dealer if needed and save a lot of money on useless diagnostics etc.

Thanks in advance

Brake light switch can be a possible cause, or in wet weather water in a wheel sensor or abs connection

I've replaced the brake light switch and that didn't work sadly.

This started after I had the n/s front shocker replaced and comes on totally random,I get loss of power steering and the ETS+ABS lights come on simultaneously...the fact if it's wet or dry doesn't make a difference.

I have it booked in with Prestige German Cars of South Shields on tuesday so hopefully they can help.

1 last question:Is it posssible that these sensors(if it is one) get dirty etc and can be cleaned?Should i try cleaning them before I take it in?

Thanks in advance

Sounds to me like they dislodged the speed sensor in the front wheel

Got the car back today and it's perfect so far,no signs of the problem

In the end it was a rear ABS sensor that was faulty so Prestige replaced it,£190 was the damage...not too bad tho I do hate getting a diagnostic charge :/

Anyways good job Prestige German Cars of South Shields,the car was still very clean inside and out so they obviously take due care when carrying out work.
