I have a 308SW that i've owned for approx 5 years (2008 model), since we have had it the Turbo has been very intermittant, most of the time the car seems sluggish to accelerate quickly however occasionally when starting the car in the morning from cold, the turbo will kick in and acceleration is rapid for a minute or so then goes back to being sluggish. I have sprayed some EGR cleaner into the turbo where the pipe goes into it which brought on the management light and depolution filter blocked message until my wife took it for a blow down the motorway which cleared the message and warning light. The garage i took it to last year stated it may just be a issue with this type of car which i just thought "here we go again, trying to fob us off". Can anyone shed some light on why it does this. I have noticed that there is quite a bit of excess oil in the turbo hose pipe (white part)when i took it off.
