hello all, anyone now about HDI turbo,s ive got a C5 2.2 its got 157000 on the clock and uses no oil and up to now starts on the button and very reliable should be i think 136 bhp or something like that, the issue is just lately it doesent seem to want to go, im wondering if its soot build up in the VV turbo ? or one of the valve avtuators to the turbo.. any help on this guys,

thanks
Andy

 

possibly the egr unit my uncle had a similar problem on his shitreon expert taxi

 

thanks mate will have a look at it, i no there is 3 electronic actuators that fail, think one is for the the turbo one for the egr and another for something else!! its just a big bus mate i use for work very comfy i just stick the cruise control on and at 50mph it only at 1500 rpm

thanks
Andy

 

check air mass readings ,or vacuum to turbo actuator valve ,inlet manifold runner diaphragm goes, so looses vacuum to all valves
