I think one of my injectors are leaking. After the car has sat for 2-3 hours or more, I have excessive white smoke on start up. It clears up within a minute or so of driving. My engine also seems to have a tapping noise when listening to the exhaust, and whenever I hear the tap, a white puff of smoke comes out. Once the car warms, white smoke disappears & I have great power & fuel economy. I tried diesel purge, no benefit. I might try it again and take the car for a rip on the purge rather then just idle/ revving.
I assume one of my PD150 injectors is leaking, when the engine is cold the fuel cannot combust. Engine warms, burns that extra fuel more efficiently and white smoke clears. Or maybe cat works and deals with the smoke? Im worried of washing the walls of the cylinder with diesel fuel. I really don't want to get these injectors pulled and sent away for testing. Any ideas? Also I should ad the exhaust tone of my TDI sounds much deeper then normal, almost like the MAF is unplugged ( brand new MAF installed 2 months ago)
thanks in advance
