Hi, I have a December 2005 CLK CDi 220. Had it for two months and am very impressed. It went in for a remap a few days ago, and before it had a health check and RR run. There is a power dip around 2300 to 2700 rpm and it shows the error code 2632 "chech charging system : charge too high". A little research suggests first course of action is to clean out the EGR valve, then process to check cat and DPF. I would therefore be veyr grateful if anyone could answer the following :- 1. Although the EGR can be cleaned, is it better to just blank it off? 2. Does the car have a DPF, or is it just a standard cat? 3. I'm told as it's a diesel the car can pass MOT without Cat, so if this is blocked or causing problems can you just use a decat pipe? Car runs great apart from this power dip and makes the power and torque it should elsewhere. Any other suggestions welcome as I need it to tow my track car Many thanks, Scott.
