Hi all, iv got a passat tdi 130bhp. On first start in the mornings after been parked on driveway for approx 8-10hrs over night, starts on the button, sounds like misfire (spluttery)(slight shudder in car) and gives out blue smoke. This only lasts for two minutes, If I rev the car it clears faster and misfire goes also. I'm not a mechanic. No fault codes or any noticeable running issues other than first two minutes of start up. Recently had seals done on injectors (month ago). Made no difference at all.
