hi all, i have 1.6 tdi cr , today while driving along with cruise control on set at 40mph, the glow plug warning light started to flash and went in to limp mode any idea's

Did the cruise control turn off as well?

The most common fault associated with the glow plug light is a faulty brake light switch, or bulb (which also knocks out the cruise control).

If the brake lights are working correctly then the car needs scanning to determine the fault.

There is a map of Briskoda VCDS owners in my signature who can scan the car.

yes, the cruise did turn it self of , i'll chech the lights thanks
