Hi all, I posted previously that I had a new recon turbo fitted after a major noise from the old one. Turbo fitted all fine from garage but it doesn't seem to boost in first at all and the. In others gears kicks in around 2-2500 rpm which it didn't before when it boosted in at around 1200 rpm.
i tested it and it said boost pressure range not reached P0299 code. Garage spoke to turbo supplier who said to turn actuator nut a tiny fraction but still no joy and I'm now left to figure it out as they have tried all number of things, MAF, EGR clean and checked for leaks.
Interestingly on way home I tested first gear buy putting foot to floor and as it climbed the revs slowly I backed off then straight back on the throttle and had boost! friend of mine wondered then if the actuator was actually set correctly as backing off the throttle would have closed the vanes and then created boost which is why then back on full throttle it kicked in. He said that that would also cause it to not kick in until higher revs if the vanes were open too much allow revs.
would appreciate any advice I don't want to adjust the actuator myself as I wouldn't want to risk screwing the turbo. Either that or take it too an engine tuners and see what they think as that is what the garage suggested.
