So you're saying the smoke is when you come off the throttle, not when you're on boost? It's your turbo. I drove mine 'til it got realy bad. didn't take to long to be honest.:doh:The problem occurs whilst driving at boost. If i drive with full boost for about 5 secs then back off i get smoke for about 2-3 secs whilst driving off boost. Im taking the intercooler pipes off tomorrow to check the turbine for play.
