Hi I know it's not a mk4 but its a w reg 2000 audi a3 1.8 non turbo and I know how helpful you guys are and have helped me out in the past with my golf turbo. Basically my Partners car starts and runs for 2 secs and cuts out, the milage on the clocks or the time are not on the dash it only has the basic warning lights working like battery EML and handbrake light working etc. there is a fault code on the system 17978 which is engine start blocked by immobiliser, I've checked all fuses(ok) my guess would be the clocks/dash it's self at fault, can anyone shed any light.
