I have a 56 plate 07 relay 2.2tdi. The engine keeps running when I turn the ignition off. Has anyone come across this before and what did you do?? So far the barrel has been changed so I know it's not the barrel. Put a flow meter on the barrel terminals and it reads 13 when the engine is running with the ignition on. Turn the ignition off, the engine is still running and the flow meter is reading 6. Any ideas anyone please. Thanks, Steve
