after the debate about disconnecting the battery for a while I thought i had nothing to lose in trying it. While surprisingly it did stop the chugging on move off I complained of a while ago that I could not cure it has somehow messed with my central locking. the doors lock when i pull away as normal but when i open the drivers or passenger door the back remain locked rather than all open, sometimes if i open the door while the engine is still on then it works, any ideas? One problem down the next arises!
