P0380 fault code

[frag45]

Keep getting a constant fault code with my vectra, fault code P0380 i took it to a garage the other day who was supposed to be car electrical experts but could not work out what it was. I have already changed the glow plugs and the glow time control unit but i am still getting the same problem, it there a relay that controls the glow plugs or is that the glow time control unit? soz but im not clued up on cars and also if there is a relay where would i locate it?

Thanks Gazza. Do you know if there is a relay that controls the glow plugs and where it would be located. i know there are relays in the engine bay where the fuses are but i do not know if one of these relays controls the glowplugs and which one it it as my vecra handbook does not tell me whet relay is what.

Tbh I wouldn't what relay you would check.

I think the Glow plug control unit (the silver box stuck to the battery case) and the Glow Plug relay are the same unit.

If you've changed the glow plugs and the silver thing whatever its called :-) then you could check the fuse, but I still haven't found where its is (I think its fuse F38??) http://www.vectra-c.com/forum/showthread.php?t=123156.

Also is the battery OK? The glow plugs need a fair bit of juice.
Also check the cable loom that goes from the glow plugs, someone on here said it can get caught against the gearbox/clutch.

If you find the fuse can you let me know where its is?

Think it might be a trip to vauxhall but i do not want to pay there prices, even got a funny feeling there going to try and say its the injector seals even though the last garage said it cant be as if it was it would happen all year round and i had the same problem last winter but when it came to the warmer seasons it started fine

Have you had the battery checked? A bad battery has been known to throw this error (and other random ones).

Also have you checked that the glow plug wiring is not catching on anything. I think this only applies to the 1.6 CDTi 150s.

Rather than a main dealer is there a Bosch approved garage near you?
