Hi All,

I've had a brief look around the forum before I posted, but, here goes.

I have a C350 Cdi 2013, occasionally after starting and pulling away and usually at about 10 mph, I get a kind of brief power loss, steering goes stiff, ABS light pops on as does a message on the dash, I cannot read the message as it comes on and goes off so quickly, there is an Anti Skid logo within the message, I've tried videoing it, but too quick! The Parking Brake light and message also flashes up!

I say 10 mph as it seems to coincide with the Auto Door Locking, I have turned this off and the fault still occurs!

On very rare occasions it will happen at about 30 mph, the LCD Radio / Sat Nav Screen dips, a bit of a stutter like a poor gear change too, I think the gear change is a red herring however, but just a brief power dip.

The ECO will not turn green either! Aux Battery issue? (Temp outside can vary from 5 degrees C to 21 degrees C).

Codes I hear you say! None stored, not on the iCarsoft or a Snap On Professional.

Once the fault has occurred initially it doesn't do it again during the same run cycle after the start.

Does anyone have any suggestions what may be going on here?

TIA

Cheers Dave

I do not have a C350 Cdi 2013.
An easy thing to do is to replace the brake pedal switch and test.

You could have a point there, I was watching a You Tube video or two yesterday and that seemed to be the consensus of opinion there too.

Just surprised there is no codes registered!

I’d take a look at live data on wheel speed, see if one is going a bit wrong

Loss of power steering at 10mph points to a wheel speed sensor.
