Evening to all, The above mentioned 407 HDi is not as good as it should be. The codes are P3008 and P0299. The DPF pressure sensor is now functioning after a few thousand K's of being US. The 6 speed auto is a bit slow at times and seems to be a bit confused sometimes as to whether to change up or down. The car has travelled about 244K's. When driving at a steady pace which needs about 2,000 RPM the engine will frequently start to hunt/surge until the situation is resolved by use of accelerator to either speed up or slow.
Research of various sites indicates a turbo underboost for the P0299 and maybe a MAF issue for the P3008. Am unsure as to an EGR restrictor, but will be by Monday. Thanks !
