A3 dashboard warning lights

[audia3driver]

Hi everyone,

Can you help me diagnose what the problem is with my 1.9 litre diesel as I have a combination of warning lights that have come on at the same time today when the engine was started. The warning lights are:
(Amber) Glow plug system
(Amber) ABS (Anti-lock brake system)
(Red) Fault in brake system
(Red) Airbag system
(Red) Electro-mechanical Power steering

The word 'dEF' also appears above the milometer 

The car recently had a major service about a week ago.

I read somewhere that DEF means that the cluster has an internal memory fault and needs repair or replacement..... 

 

Could be causing all the other lights too?
