hi , iv had problems for the last few months with the service light coming on and restricting the car to 2500 rpm, i had the codes read and found out it was the egr valve and a glow error,, the guy told me 8 times out of ten you can clean it and armed with that i gave it ago , iv cleaned the egr valve best i could using carb cleaner , while i was at it i cleaned what i think is the inlet manifold? where the egr valve connects,i had to undo the fuel lines/injectors to get this off for cleaning.. anyway iv put it all back together and now the car just will not start iv tried to blead it but the injectors are a night mare to get to and i managed to get one off theres barely any diesel coming through any one got any ideas whats gone wrong? cheers in advance
