Hi folks.. first post, but have "lurked" on learned a lot! Have a w203 C270CDI first reg 03/03. Starting from cold ok, but when hot wont start, turns over ok, but will not even try. Main dealer diagnostics say injector down and losing pressure when stood. Being a simple soul, I thought replacement injector and perhaps a seal or two! Wrong! - "Sorry sir... 5 new injectors, new seals, new pipes = £1100.00 plus fitting" Cant seem to get a definitive why, just that the original set up has now been modified, with originals no longer avaiable. Anybody with any information care to enlighten me before I part with my wifes next years clothing allowance??
