So, my e320 4matic says "ETS" then "BAS" then "ABS" at startup. Took it in, they wanted $1200 for the ETS pump plus three hours of labor.

The ETS pump in key position 2 buzzes quite loudly, like it is stuck. I tried tapping on it with a hammer to free it up but no luck.

Any advice is greatly appreciated.
 
Anybody? :confused:
 
whats an ETS pump ? :confused:
 
Electronic Traction System pump. That's what. :crazy: It's an add-on to the ABS since the ABS system can detect spinning wheels as well as locked ones.
 
OK, I discovered the third tail light is out. One dealer's service dept. I talked to said to check the tail lights, and we forgot #3 (rear window deck).

Could this be the problem?

If so, dealer #2 owes me $100 and an apology.

Can anyone tell me, however, how to get at/change that stupid bulb?

Just pull the cover from the inside of the car.
 
OK, bulb replaced, still the same errors. Argh.
