P20CC-08 error code, abs and esp dash warnings
2004 e320 4matic wagon, sbc replaced ~3 years ago by local dealer (ripoff artist we no longer frequent, we go 70 miles up the road now) with a story similar to other frustrated w211 sbc sagas told here.
Trying to figure out what's going on.
Took it to O'Reilly's, they used Bosch obd 1300 and after some fiddling the counter clerk got it to display
P20CC-08 'Rough road detection' signal (by comparing wheel speeds) :Speed signal from control module ESP implausible /Read out fault memory of control unit ES
I get white ABS and ESP errors on the dash at engine start. Steering is a little heavy, brakes are a little heavy but nowhere near as bad as when the SBC went completely belly up a couple of years ago.
Any help would be appreciated. Is this a diy moment or a get thee to a trusted dealer moment?
In the past I've done basically all maintenance myself. But these newer cars seem to be designed deliberately to require the dealer ripoff artists to stay running past end of warranty. Which is why I bought a W210 after our experience with this lemon.
