Glow Plug light / loose connection to ECU?

[jme808]

My car is out of warranty in a couple of weeks.  It was at Skoda Platinum today following a glow plug warning light, that has happened 3 times in the last few months - always when in gear going downhill with the engine under braking.

 

Skoda had the car for a few hours, and advised that they couldn't find a fault, but noted that one of the plugs going to the ECU wasn't properly connected.  I've taken the car away, and was told to expect a call from the dealership as I had concerns that if the fault reoccured, it wasn't going to be covered by my warranty despite the fault being found before the end of warranty.  I didn't get a call.

 

I'm curious if anyone else has had similar symptoms that have been cured by loose connections being sorted?

Check your Brake Light bulbs are both working.

Thanks goneoffSKi, but It's not the brakes - am aware of that issue.  I changed the bulbs / cleaned connectors on the off chance one of them had a fault - no joy.

If it's flashing it your brakes if it on constantly it's a glow plug fault.

Its some sort of fault, probably electrical but unlikely to be a glow plug fault. The light doubles as the CEL.
