GT JTD Swirl Flaps
07reg, 98,000miles with Alfatune remap
On Saturday when not long after starting up it lost power and was slightly hesitant. Checked all the hoses and levels which were ok so limped home at 40mph. Did some searches on here and checked the EGR (ok) and the MAP sensor (gunked up), on starting up was still hesitant but went for a run and it certainly seemed 99% better but smoked when accelerating.
There was something still amiss so i called Ned at Autolusso and limped it over to them. The diagnostics showed a swirl flap error and Ned said it could either be a failed swirl flap acctuator or unusually for a late JTD the flaps could be bent after being gunked up. The inlet manifold was taken off this afternoon............
Ned then called saying that all the flaps were heavily gunked but the flap for No2 cylinder was missing and the only place it could go was into the combustion chamber!. I knew BMW's had suffered from the flaps coming off but had never heard of it on the JTD's. The inlet manifold was put back on for a compression check and yes, No2 was flatlining.......happy days!. The head's now coming off tomorrow to see what damage has been done.
