pre heating lamp ON 10 sec after engine ON (1 Viewer)

[andrea-PE-ITALY]

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....

see the section:Systèmes anti-pollution du moteur 1HD-FT
I've the same problem since Intercooler, code 71, and i think, the air temp detected now, is too low.
