New to posting threads having joined almost two years ago. At that time I became frustrated with my March 2001 CL55 AMG hence the name - soonxmercs. Purchased from a Mercedes 'stealer' in Dec 2004 and regularly MB serviced I formed the view that these cars are far too sophisticated for MB mechanics. With the bulk of depreciation behind I've been unable to part company with the beast. A beast it has become. Last Saturday, after driving a few hundred yards the 'Display Defective - Visit Workshop' warning illuminated followed by the intermittent loss of numerous functions. In no particular order satnav, cd, fuel guage, washers/wipers, outside temp/clock/gear setting, indicators, power windows, heating and lights went and came. Other malfunctions listed were, side marker light RH(?), washer fluid - check level and low beam fault - check lamp. The parking brake warning - 'brake' - was intermittently illuminated on the dash. Chip Card Not Recognised also featured. The battery and alternator were renewed in June 2010 (MB), however, in Feb this year after 10 days at Gatwick the battery was flat. A few weeks ago after sitting for a week or so the battery was again flat. Checking here for similar problems I have lifted the passenger side carpet and all seems bone dry - some cobwebs all intact! Mercedes couldn't fit me in until 2 January so I am willing to try any simple solution such as brake pedal switch or new battery. MB seem to think it's SAMs. Apologies for the longwinded first effort thread (more omitted!) but any advice would be greatly appreciated. Best wishes to all this Xmas.
