I sprayed it in where it is marked on the photo. Be prepared for a LOT of smoke. Someone stopping because they think the vehicle is on fire amount of smoke. Not something you want to do on the local street.

The revive stopped the fault for normal driving but not for towing. Since using 2 stroke oil I have had no more faults when towing. Using the GAP tool the boost pressure actuator is moving smoothly again.

One litre of 2SO for the first 4 tanks then 300ml per tank after that. Have you tried freeing the actuator. This worked for a number of years before using 2SO.

It might be worth checking the turbo intercooler for damage. My 05 Disco was smoking and we found a split in the cooler was upsetting the fuel scheduling. It may be a cheaper fix than the turbo!

I'm still in the air on a 2006 Discovery 3.project vehicle. So i read these posts with interest. It appears to be an expensive fix with multiple issues. Would not a good scan gauge show a fault with the cat , (i would assume over pressure ) . Its a learning curve . Baz
