Thread: Secondary Turbo Charger problems My12 SDV6 HSE Disco 4

Try disconnecting the lower intercooler hose from the secondary air control valve and draining out the oil thats in there, after the car has sat for a while, overnight maybe. Access is easy - turn the steering full lock right and you remove the lower plastic shroud inside the wheel well. Last saturday i collected about 1/4 cup. Just thinking that the turbo is suffering because its ingesting a lot of oil from the intake system.

Another concern is that when my wife drives it (Like a Nanna) even if its just for the day then I drive it the exhaust produces a fair amount of smoke. Then seems to clear and then is the same the next day etc etc etc.

I do not think it should be producing the amount of exhaust smoke as it is. Maybe its just me

I wonder if your wife notices - mine would not - it is just a car.

I haven't had the drain mod done yet but about to. 90kms

I can predictably produce the smoke from standstill with moderate throttle after a fairly short light cruise .... It has been handy for tailgaters but seems a bit OTT in the middle of the city....

Maybe something else is wrong.
