Hi
A flashing glow plug light could be a number of things it needs to be plugged in to a diagnostic machine to read the fault codes
Hope this helps Nick

I don't have the solution but a possible help in diagnosing. If you remove the water temperature sensor connector from the sensor, the glow plug light should stay on when you go to start the car. Try leaving it on for 15 seconds and then start the car. If it starts right away, it is your sensor. If it doesn't, the good luck.
The sensor is located on the right side of the engine near the top, at the back. It is in the coolant fitting directly behind the hose from the rad, just left of the thermostat. Be careful to disconnect the wires, and not remove the sensor, or you will loose a lot of coolant. The sensor is held in by a separate plastic clip, and the harness just has a little built in clip on the side. Hope you have small hands...

this means you most likely have a burnt out glow plug or glow plug timer control or both

The Glow plug coming on, and the car going into limp home mode, is a default safety feature that occurs when the engine management system picks up any kind error message from the many sensors now used on the car.
I've found the glow plug light problem with my Jag, it was the air filter. Apparently Jaguar servicing change it every 3rd service (not a good idea). I changed mine, it is a new car. I had the EPR valve cleaned and a major diagnostic carried out by a local garage (who had the Jag diagnostic software). It turns out I also need a new Turbo; the actuator is sticking (£759.00 plus 3 hours labour). But hey, the main limp home mode problem is fixed and I can drive my Jag confident it will accelerate when press the gas.

this is a common problem for these cars glow plugs go bad like spark plugs however the smoke would lead to bad mass airflow meter. it is not telling ecu corrcet miss. disconnect mass airflow meter. when cold see if this makes it start better. it should would means you need new m.a.f. glow plug issue take a test light place clamp on positive of battery then pull off glow plug connectors place tip of test light on glow plug the bad one will have a dull light unlike the good one which will be brighter. will need new plugs and wire harness four **** connectors and wire striper and crimper will fix concern good luck

the car is going into limp mode due to an engine management fault. have to check what the fault is with a code reader. if the milage is high 100,000+ could be a turbo fault (overboosting), as this will put the car into limp mode.
