I have an A6 estate N Reg the has been off the road for several months, I strat and drive it once or twice a month. However, today I appear to have not tick over, could this be due poor connection at some point as the car has had little use or a failure of the control system.

I have tried to get a manual but none in stock at this time I need to MOT this car and would welcome any help in identifying and finding this problem.
