Since I bought the car (mk5 Golf GT TDI) I have been convinced that the glow plugs needed replacing. When starting the car from cold it often takes a couple of seconds turning over before it picked up. I have had the battery tested and that isn't the problem as it is running at 90% capacity.
The other day the glow plug light eventually came up and over a couple of days with the engine management light, glow plug light and an annoying beeping sound every 15 seconds being told to "Take the car to the workshop" it has now gone off?
Car still takes a couple of seconds to turn over but the light hasn't come back on.
Has this happened to anybody before?
Is it definitely the glow plugs or is there a chance it could be something else?
p.s I have also ran cataclean through my system which I understand cleans the injector heads and there was a slight improvement since this.
Thanks :)
