2011 S60- Intermittent limp mode
Hi all own a 2011 S60 Twin turbo D5.
For the past 3 months I have an intermittent fault.
Under boost- normally higher in the rev range the car goes into limp mode.
Only fault code is p029900 - Turbo underboost.
The car drive for 10 miles and be fine all the way too work. Other times it is awful - almost continually flat.
I am actually in the trade. Smoke tested the vehicle, cannot see any vac leaks at all. Put some turbo cleaner through the system and it improved it for a week and then got worse.
Any ideas?
Jim
