Have had similar symptems on mercedes vans in the past it
is a indicator to let you know that one of the heater plugs has failed.

It could indicate a fault in the engine management system. If the glow plug light stays on or flashes it may be similar to VW diesels. It may sound bizarre but a glow plug warning light staying on could indicate that the brake lights are not working (i.e. faulty brake light switch). Is it an AUDI dealer selling the car? If so get the dealer to plug the car into a diagnostic machine to see what's going on. I wouldn't buy it until the cause is known.
