RE: HELP Range Rover 2010y 3.0 SDV6 problem
The codes suggest to me that the issue is with the secondary turbo inlet valve, also called fixed vane actuator. This is a vacuum controlled valve on the back of the secondary turbo, which when commanded by the PCM opens and allows exhaust gases to spin up the turbo. The valve is operated by the left (grey) (as far as i can remember) of the two vacuum solenoid valves mounted above bank 2 timing belt cover. The other solenoid valve operates the CSOV or compressor shut off valve which opens to allow the boost pressure from the secondary turbo into the engine. The CSOV is located near the rad pack
The code that it the key to the fault is P22D2-77. This suggests the valve is being held open. Most likely cause is a faulty solenoid valve. To confirm, I would advise you to check that the solenoid valve is NOT permanently supplying vacuum to the secondary turbo inlet valve if it is, it could be a PCM internal fault (quite rare but not unheard of) or the solenoid valve is stuck/failed internally (much more common) Vacuum should only be present when PCM commands for secondary turbo. To check this at idle speed, connect vacuum gauge to secondary turbo inlet valve end of the vacuum pipe, and start engine. No vacuum should be present (if it is, that is your fault so check solenoid is working and that PCM is not permanently grounding /supplying) Leave engine to idle and after 2 -3 mins vacuum should be seen. Now blip the throttle, vacuum should be dumped straight away, only to return after idling for another 2-3 mins. Other thing to check if the above tests don't show up a problem
Hope this is of help, if you have any more questions about the above PM me or reply |
