hello, everybody!

i'm new here but i have a problem with my stilo 1.9jtd from 2002:bang::bang: i have always the preheat fault but i've changed the 4 glow plugs and also bought a new preheat relais ( for the power to my glowplugs) and i still get the message after starting the car "preheat fault" somebody some advice ? :worship::worship:

thx

Hi, Welcome to the forum.

Check the large fuse F4 (50 Amp) in the engine fuse box.

Check for power at the bolt-on terminal of the relay, and earth at pin 5 of the relay connector..

The wiring between the relay and the glow plugs sometimes causes a problem. Check for continuity between pins 1,2,3 and 4 of the relay, and the respective glow plug.
