t5 transporter glow plug light comes on when driving

[tofast525]

I know I will have to take my t5 to local dealer for rectification of problem, but they do not come highly recommended
anyway has anyone else had a problem with their 2.5 TDI where on deceleration down hill the glow plug light and engine work shop warning are displayed on dash? the ute runs fine and once you accelerate again the lights go off. took to regular mechanic but he had nothing.
any ideas would be great

Get codes read off your OBD port, there should definately be some stored in the ECU
Flashing glow plug light by itself is usually related to a faulty brake light switch, not the case here.

Agreed, needs to be scanned.
