    3 days ago i was removing all vacuum relais for EGR and cold start engine cause in italy we have not -20 C° and EGR for making space for my new home made intercooler kit. now, on switching on engine it's all ok but 10-15 sec after the lamp of air preheating switch on again and do not switch off until i switch of engine. if i run engine again same think, preheating 1 sec, pre heating off, 10-15 sec later pre heating fix switched on. what do you think about? i leaved piping from turbo to altitude compensator and vacuum tube to cold start bulb. Engine runs well, no strange lamps, but this mad lamp is alwais switched on....:crybaby: :confused:
