Galaxy tdi loss of power

[stevov60]

Hi Chaps, First post on here!!! My 03 Galaxy tdi starts and drives fine when cold but as it warms up i get an intermittent loss of power right through the rev range.
To me it feels like the turbo does not cut in at all. It has had a new turbo and full service recently.

Any help will be very helpful...Steve.

First thing i would do is look towards the air flow metre a known weak point. Be worth giving it a clean to see if it makes ant differance although needs to go on a diagnostic machine to check what readings its giving to be sure though.

Would that be the disc shape silver thing behind the oil filler cap?

No there is a sensor housing next to the air box with a plug on it just take it off clean it out with some carb cleaner or similar

Done that with no luck. The whole thing looks new to me. I also tried it without it plugged in aswell and it didn't make any difference, which is odd?
