2005 CLS 500 Speed Sensor

[Aaron-P85]

Going round a roundabout this morning and BING... ESP/ABS lights kick off and the steering gets very heavy...plug it into my £20 OBD reader and it tells me it's the front left wheel speed sensor (although I thought they're called ABS sensors?)

Anyway.... where's best for this part? ECP only quote for the rear sensors?!
Cheers

Don't discount the dealer either. They often match or beat prices elsewhere.
Have you tried Car Parts 4 less and GSF?

Hi AMGeed,

ECP and their sister company carparts4less sell the same item (rear left/right) and surprisingly at the same price, usually the latter is cheaper!! hmmmm

Do you or any forum members have experience of the one you've linked to? I'd hate to buy it only to fail a month or so down the line...
GSF are coming in the cheapest so far...does anybody know the maker of said sensor before Mercedes brand it as their own?

Regards
Aaron

No experience of Febi sensors Aaron. The only ones I have replaced in the past (CPS) have been Mercedes supplied.
I still think the dealer is your best option.

I'm not doubting your diagnostics but I'm interested to know why an ABS/speed sensor failing would cause heavy steering? Does the car revert to a default setting and weight up the steering feel?

Obviously one occasion when the dealer isn't competitive .........but it's a Mercedes sensor and not aftermarket you would be paying for.

This was my thought, because when I start the car after an hour, the lights are not on, but when I go above 20mph they light up like a christmas tree, my only thinking was the car doesn't know if I'm on the Motorway doing 70mph (officer) or on a roundabout doing 10mph so chooses the heavier setting?
Steering is fine when I first move the car too, but the second the lights come on , bang, heavy steering again.

Theres a lot of safety interlocks between systems.

For instance, on a SL, if the SBS brake controller fails (it has electronic brakes) then the engine goes into limp mode firing on less than 8 cylinders, speed gets limited, and if I remember it won't change up a gear, only down until you are basically stuck in 1st.

I suspect there is some logic between the speed sensor fail and the steering becoming heavy. Of course without the speed sensor you lose all the braking extra safety systems ...
