I have a Citroen Berlingo 1.6 HDI Turbo has 2 problems in the morning in Relay works very badly that takes temperature the problem is removed and the other problem is the exit of the engine gases those who take the turbo with the air intake take the gases sucks a lot
Well that fault can be from the turbo itself as this burst, to a rings problem, because of the general is the problem of the turbo, check it that is not passing oil from the cello of the inner turbine, clean it and you have the test.
