High turbo boost pressure fault on a CR-V?
I am touring on the continent with my 2005 CRV 2,2 CDTi (89,000 miles) towing a caravan, which I have done with this car since 2007 when I bought it. Cruising at around 50mph on the motorway the engine suddenly lost power, the engine management light came on and the car went into limp home mode - it would not rev over 2200 rpm.
It was towed to a garage (Bosch Service agent) who said that fault was registered was high turbo boost pressure, but say they have reset the fault code and cannot reproduce the problem, so no faulty parts found or replaced. Of course I'm very worried that it will happen again as I have over 1000 miles still planned on this trip.
Any suggestions? Is the car susceptible to turbo problems at this age? Does this car have a variable vane type turbo or wastegate for boost pressure control?

Might have overheated the turbo.
Vital when towing with a turbodiesel to idle the engine whenever you stop for at least 2 minutes before switching off. The reason is to keep engine oil circulating through the turbo bearings while the turbo impeller spools down.
Try to use only the best (highest lubricity) diesel.
If you can find any lubricity additive (might be labelled fuel system cleaner: Wynns is a good one) add that to the tank.
Can't be a DPF problem because the CDTI (thankfully) doesn't have one.
