If you own a Mercedes ML W166 Adlue Engine Start Not Possible is written on the instrument cluster display then it means that you have driven past the safety start limit.

At this point the car will need to be towed to the dealers and alot of work needs to be done to program and reset this error.

If you have limited miles remaining , make sure you fill at least 20L of adblue which is readily available from most petrol stations then call us , bring the car to Revtronic and we will reset , relearn and program the adblue system back to normal.
