this is a 3.0l tdi by the way...... So yesterday I had a custom map, egr, dpf delete and also had the cat removed. All fine and dandy. On the way back I was following a friend who gave me a lift to collect my car. couldn't resist, I over took him and met him back at mine. He told me as I was booting it, there was quite a bit of white smoke coming out of the exhaust. Thought nothing of it, I thought dpf and cat only just been removed so expectable and wont happen again. Today I get in the car, it struggled to start and took a lot longer than usual. When it eventually started the amount of white smoke coming out was embarrassing, I drove off and left quite a trail of it too. After driving off , by the time I left my estate it had all cleared. ive had diesels with dpfs removed before and on a cold day (night especially ) the do give off a little white smoke. But nothing like this, plus it was nearly 17 degress today which is what panicked me. I don't really no much about the 3.0 so maybe its to be expected when dpf and cat is removed. Im working early in the morning so will be interesting to see what its going to be like when cold.
