CHECK ENGINE LIGHT-P20BD?
Hello all, I have a 2010 ML350 Bluetec and I just got a CEL-p20bd (Reductant Heater"b" control circuit open")...
I was in Vermont this morning and the temperature was 1F and I got the cel as soon as i started the car. what do you think this is?
I just did a reset with the little scanner since driving back home to NY the code didn't get erased. so I deleted the code after driving for 5 hours. I just hope it doesn't come back on.

P20BD rotate angle error between left cylinder bank camshaft and crankshaft (P0378)
Your code seems to be for a Ford.

Sounds like typical cam magnet problem (Just a wild guess)
Don't clear codes if you have a CPO warranty, get everything you can fixed.

I have similar problems as well. My check engine light is throwing 3 codes:
P2069: Reduction heater 'A' control circuit open
P2005: Intake manifold runner ctrl stuck open bank 2
P2413: Exhaust gas recirculation sys perf
I reset the codes, they come back right away. So booked a service appointment next week. Will let you guys know the outcome, but my psychic powers tell me this is a 4 digit fix $,$$$.
