What does it mean if the glow plug light is flashing?
engine management unit
If you have a Glow Plug Indicator flashing, it’s likely that your vehicle’s ECU (engine management unit) has detected a fault that can be related to the glow plugs, the glow plug light, the glow plug control module, or even sensors that aren’t directly related to the glow plug igniter itself necessarily.
What happens when glow plugs go bad?
Faulty glow plugs may disturb the sensitive diesel combustion process, which in turn might result in the engine producing black smoke from the tailpipe. This is a warning sign that something is wrong either with the glow plugs or other vital components of the combustion process.
What is the difference between glow plug and spark plug?

Hope this is the right place to ask. Anyway, driving into work today (in my VW Golf Mk6 1.9 TDI Bluemotion) on the motorway, cruise control on – set at 60mph in 5th – I was greeted by a ‘ding’ and the flashing Amber icon for the Glow Plug and a message of ‘Engine Fault: Workshop!’ on the dash.
Why does my VW turbo light keep flashing?
Also this tends to lock the turbo solid so the engine can’t breathe and it leaves you stranded with a collapsing inlet pipe. The breakdown chaps often carry a spring that they put inside the pipe as a get you home fix. It would make sense to get a fault code read done and if it is an over boost situation, have the turbo rebuilt before it goes pop.
