ABS/power steering.

Twice now, the ABS warning light has come on.

Once last night in very wet weather, and again this morning in very wet weather.

When I started out this morning the ABS light did not come on until a few minutes into my journey, and several very deep puddles and small floods.

At the same time the power steering gets noticeably heavier.
I thought it was just my imagination but after a brief stop when the ABS light did not come back on, the steering was back to normal.

The question is...is there a link of any kind between the ABS and the steering? I believe my car has parameter steering which is an additional electric assistance to the rack.

On the wife’s B200 we had a similar fault, ABS light and heavy steering, it can be caused by ABS sensor failing, after I changed those the problem continued, in the end it was the magnetic ABS seal fitted to the front wheel bearing.

Since I posted I've been able to read the codes. It is likely the YAW sensor.

Thanks for your reply.

I get periodic yaw sensor failure errors too, on my 2005/W209. I clear the fault using a code reader and it goes away for another year or so. The ABS/BAS/ESP all continue to work fine. I suspect either a dry solder joint in the module, or the sensor is starting to drift with age. One of these days I'll get around to taking a closer look.
