Well more by luck than judgement. I got rid if my ABS and ESP Currently unavailable messages. And the Parking Brake See Owners Manual message. - by Resetting the Electronic Parking Brake.
All seemed fine ...other than my defective low voltage battery issues. (But now convinced thats not relevant to these ABS and ESP or EPB issues.).
Note Prior To applying this “fix” I had cleared down all the fault codes.
So I gathered up courage to use the MBII to see if any N47-5 [ESP Controller] errors were present. Thinking if there are any lets clear them down now the problem is solved.
Started the car with the MBII connected ... and the ABS and ESP msg. Flashed on and off.
Went through and cleared all the codes ... checked OBDII still had no faults ... it didnt
Checked the Fault codes on the EPB ... no fault codes, but as I did .. I noticed it disengaged the EPB. Odd?
Then I noticed the engine, that is normally smooth as silk started running lumpy. Wouldnt rev smoothly.
Checked still no fault codes anywhere.
Turned her off and removed key. Then Removed MBII
Started her and all the dam ABS And ESP message crap was back per normal.
I Re-Applied the Electronic Parking Brake reset, and thank God it all worked Perfectly. Smooth engine no messages whatsoever.
I repeated this sequence 3 times. Every time the MBII f@cked up the EPB, and caused a rough engine and all the ABS and ESP messages returned and it disengaged the EPB.
(Note it found no OBDII faults or benz faults other than it brought back the ABS and ESP faults.
And had some of my undervoltage fault codes).
Every time I applied the EPB fix ... it cured everything!
Silky smooth engine .. no ABS and ESP or Parking Brake messages.
So either the MBII (on the latest software), dislikes my CL500.
Or the MBII is malfunctioning with my car when its got low voltage. It however finds no fault codes for the CLs Diagnostic CAN etc. Or OBDII faults.
On one hand very pleased I dont need a £641 EPS controller or a £90 brake switch.
But sad I dont feel happy using the MBII, which was useful.
Note my MBII unlike Johns, would not even begin to read my Comand, and now the Option does not even appear?
Getting a replacement or refund from Diagnostic World will be a mare! As they dont even answer my emails regarding the Command issue.
Obviously with my low voltage battery issues .. I kept using the MBII. And inadvertantly causing the problem.
F*ck what a journey!!
Actually they will refund the money or replace it .. as its a serious safety issue ... that electronic parking brake can be applied as an emergency manual brake ... imaging if that came on full strength when you are tanking it!
