Hey All My Car Audi A4 Avant TDI 1998 Its had new glow plugs I am down to sorting the last problem on the Audi J Right when I go to start it in the morning I need to warm the glow plugs a good 5 times this seems to be because the glow plug light literally comes on for a second then flicks off so I assume the plugs are not getting a good heat to start. The garage checked the car out and said all the glow plugs are fine. They are unsure on what to do? I need to heat them a good 5 times to get the car to start. Car runs perfect and will start first time when its warm. Any ideas?
