These warnings appear on dash usually after 10 minutes of driving. New brake switch. My buddy guesses maybe wheel sensor. Any of you guys experienced this?

1998 w210 e300 TD: egr delete, muffler delete, amg 18s, I love this car!
1995 w124 e300 diesel: bolted on junkyard w210 turbo.. yes you can "easily" boost your om606na! RIP
1991 w201: putting the om606 na to turbo into this. Not enough hours in the day!

On our 210 wagon, a similar ESP /ABS fault occurred due to brake dust (200k mi worth) building between the reluctor wheel teeth (fronts only, rear was clean), giving errant signals.  Would cause the car to go into some sort of frustrating limp mode over ~60mph (trans effectively in neutral & no throttle control). Was SO much fun on a two lane highway with no shoulders in late december with a 3 month old on board...).  A restart would clear the fault for long enough to limp to the next pull-out.

Anyways, cleaning the reluctor wheels cured the problem.  I also replaced the brake switch first, but this had no effect.

Both sides were pretty packed with crap - I had to pull the entire hub off (the gears are behind the dust shields) but you might be able to see in there if you pull the abs sensor. I doubt you could clean them through that hole however. Good time to inspect the wheel bearings, I guess...
