after fitting new plugs did u notice if light stayed on longer than it did , I had an issue with smokey start up as it was turning over a few times there was unburnt diesel causing smoke , anyway I tested glowplugs with meter all 3 open circuit so replaced , after replacement problem solved and noticed glow light stayed on longer as a result of working plugs , as previously stated there are different plugs for the a2 depending on age and model and are colour coded plugs at the insulator , I ordered bosch plugs using vin number as reference as wasn't sure if old plugs were correct as all three open circuit
