turbo charger not working due to carbon build up

15 Nov 2019 •
when accelerating hard there is a distinct power lag & a loss of power going up hills.My mechanic tells me the various hoses affecting the turbo are blocked with carbon . Is there any way I can clean them myself , & if so how do I go about it ? Any help would be greatly appreciated.

the brake lights on my 639 vito stay on when ignition is turned on, if you disconnect the brake switch and then reconnect it with the engine running everything works ok, once you turn the ignition off and on again all three lights stay on any ideas
