Hey guys I’m new here
I have the dreaded p0299 turbo underboost code and it’s driving me mental ill clear it and it’ll be fine for 10-15km or so then comes back on I can see on my boost gauge I’m only hitting 18-19psi or so and can hear a hissing noise coming from the engine bay I can’t for the life of me figure out where it’s coming from!

The hissing noise would have me looking for air leaks in the pipes/hoses that run from the turbo to intake first. Especially clamped areas, in case a clamp has came loose.

I’ve gone over all the clamps and piping from the hot and cold side it’s driving me mental trying to find this I don’t see and leaks visible on the charge pipe either
