I have got a 2009 fabia 1.9tdi, a few days ago the glow plug light started flashing with engine fault workshop displayed. 

It then went into limp mode 20-30mph stopped turned off ignition and started up again, now out of limp mode but glow plug flashing and message still on and cruise control inop . Pluged in with a basic fault code reader no codes. I have been using the car with the warning on the dash got to work this morning and 1 of my work mate was behind me and told me both my main stop lights were out. 

I have changed the bulbs now all OK, no warnings cruise working and no limp mode, how can blown stop light bulbs cause all these problems. 

Its a way of telling you that you have no brake lights

But why did it go into limp mode and was saying engine fault on the dash 

The 1.6 says “esc error” on the maxi dot when the brake bulbs are dying but not yet gone, no error codes are given either.
