gavin.starr Posted May 31, 2009 Share Posted May 31, 2009 ive been through all the threads on this but none of them seemed to come to any conclusion. basicaly ive lost all the boost from my second turbo, ive done the tinfoil test where you wedge a bit of tin foil between the valve and if it opens the tin foil will fall away as its no longer able to hold it in place. it fell away so they are both working. ave also tried it in ttc mode which still lacks boost all together. ive rummaged around all the pipes and none have split or ruptured or popped off. the car doestn smoke when driving but for a while now on start up it has given a white ploom of smoke. it has been using a bit more oil than normal over the last 2-3 months. is it now that the turbo has gone now and needs replacing. or is there something ive missed and ned to have a look at. cheers gav Link to comment Share on other sites More sharing options...
Gaz6002 Posted May 31, 2009 Share Posted May 31, 2009 Are you sure it's white smoke? If it's using oil I'd expect it to be blue. If it's blue I'd say your turbo is gone. Link to comment Share on other sites More sharing options...

hadyn Posted May 31, 2009 Share Posted May 31, 2009 It sounds like one of your VSVs in knackered. Do a search on VSVs Link to comment Share on other sites More sharing options...
gavin.starr Posted May 31, 2009 Author Share Posted May 31, 2009 ive been through all threads on vsv's but it stated that the ttc mode bypasses them so i tried it in ttc mode and still a lack of boost. Link to comment Share on other sites More sharing options...

hadyn Posted May 31, 2009 Share Posted May 31, 2009 Stuck actuator? I would try a second hand set of VSVs 1st before contemplating shelling out big money for new turbos. Link to comment Share on other sites More sharing options...
gavin.starr Posted May 31, 2009 Author Share Posted May 31, 2009 im not 100% clued up on this, but why would i need to change the vsv's if its going to be a stuck actuator. are they the same thig or does one rely on the other. ive tried it in ttc mode an the actuator opens as it should, is there anything obvious that i have missed gav Link to comment Share on other sites More sharing options...
