my friend is having trouble with his 06 vec diesal he was driving down the road and then had loss of power and black smoke and warning light saying air leak had a look for loose pipes and cannot find any .??? any ideas on what to look for next

[luke4487]

the warning light actually says air leak? definately sounds like you've got an air inlet problem.. Mines petrol, but im sure black smoke on a diesel is badly burnt diesel?

Start at the filter and work back. Sounds like you either have a blockage, or you're losing air where you need it most (i.e between the turbo and cylinders). Probably the latter if theres actually a warning light to tell you this. Cool idea lol

Check the boost hose.

Hi jb as st says check boost hose but make sure nose clips are good ,they have a habit of stripping threads
