Glow Plug Dashboard Light Stuck On

[Guest Stephen345]

Hello,

 

The orange glow plug light is permanently illuminated on my dashboard (I don't think you see it in normal use, I never knew I had one until it went wrong!). The garage read the codes and said it needed a new relay. Apparently to get to the relay you have to remove the bumper and headlamps, so it took some labour charges just to get at it. They have replaced the relay but the light is still staying on. I have had the codes read again and it says "short circuit positive side of relay". Unless the new relay is also faulty, what could be wrong? I was going to check the plugs but getting at them could be tricky (see other post).

 

Thanks.
