Mini Cooper Clubman engine stalls when warm, possible cylinder 1 failure and short circuit issue on Mini Cooper Clubman

Some Mini Cooper Clubman owners report experiencing engine stalling issues when warm, particularly when coming to a stop. This stalling may be linked to problems with the coils, especially if aftermarket coils are overheating and require replacement. Additionally, if the stalling occurs once after the ignition has been off for a while, it could be due to the engine shutting down or a tug on the brakes. Persistent bubbles in the coolant and coolant loss due to excess pressure when the engine warms up may indicate a head gasket or cylinder head issue. Furthermore, some owners find that their engine runs fine when cold but stalls when warm, suggesting potential fuel delivery problems such as clogged injectors, a dirty fuel filter, or a failing fuel pump. It is advisable for owners experiencing these symptoms to have their coils, coolant system, and fuel delivery components thoroughly checked to diagnose and resolve the stalling issue.
