I was looking for somethng on the web today and happened upon this site - mainly for Renault issues, but they have some cheap fixes / parts for certain models of Citroens exhibiting some common problems. I have copied the links below for anyone interested. Mainly cheaper alternatives to the Heater Resistor, Faulty Indicator plungers in DAV comms 2000 units and Window Temic Module. I've not used them - but thought it worth a look for those with these types of issues.
