I know this answer 8 years too late but it might help someone else. This is a typical pressure reservoir fault. All you need is to change the 2 pressure reservoirs (actually you can change all 3) and that's that. Parts are 150 dollars each and relatively easy DIY. In fact, many faults in ABC happens because these are not changed regularly (6-8 years). These save the lines and help to push fluid into struts when needed. if they are ruptured then the warning signs come up at deeps in the road.To Slonar 21:
Thank you for responding. The mechanical warnings are making the noise; warning's are red. They flash really fast; can barely read them. No oil around car. No lowering.
Mechanic is very good; only works on MBZ and is in high demand. That said, he's so busy that it's hard to even reach him. Will get second opinion. BTW: No problem raising and lowering car with switch in cabin.
Just became member to benzworld. Should I be responding here or in my email, where I was alerted to your message?
thx
Change pressure reservoirs DIY...I am so very grateful for your wise advice and I will listen clearly to it and go to the garage tomorrow.
But my CL 600 year 2002 seems to intermitently give me the ABC warning. Mostly the grey 1st dashboard warning regularly and rarely the red warning. But the red warning ABC Light does come on. There is no consistency. I was driving the car all day today and NO red warning but many grey (1st ) warnings on the dash.
Is there anything I can do in the meantime before going to a mechanic? I am mostly completely ignorant of anything techinical but terrified as London garages charge a fortune and you often cannot get a straight answer.
Is it just wishful thinking on my part that this is just an intermitent issue? I hear from many that sensors on the CL600 are too sensitive or am I just wishing/praying and justifying this ABC issue....?
I could not possibly be more grateful to anyone that could help. I thank you in advance.
Best wishes,
Giles
