I used a blow torch to light a couple then put the lid on. Also put some doubled over fly screen material on the outlet as a filter of sorts to stop any particles entering the intake.
Worked a treat! It was my nine year old’s idea to use mozzy coils [emoji106]
Thanks for the post, had a similar issue recently, same DTC, interestingly not towing or under heavy load, just cruising steady at 100kmh. The code I received was P2263-22, restricted performance came up.
cleared code by itself after shutting the engine down. It reoccurred the following day. Took it into Southern Landrover for a check in case it was the turbo actuator. They could not determine where the code came from, turbo actuators both fine.
With the engine off I used a smoke machine kit (uses baby oil which creates a thick white smoke) and the required adaptors to seal the intake just after the MAFs. Even wedged the throttle wide open and ran the smoke for about 30 sec to fill the intake and throttle body, then checked all over for escaping smoke, I couldn’t see any. I even stuck the smoke maker up the exhaust pipes as sometimes a leak at the exhaust side can apparently cause this code. No smoke detected.
Next step is to check and clean MAFs and MAP. I’ve replaced throttle body y piece o-rings and the main plenum to throttle body seals last June.
Also planning to do an injector bleed off check, will report back how that goes.
Interesting, mine did not although it was only on the 3rd such occurrence that I tested to see if it would self clear.Quote:

Error hasn't reoccurrred again since 2 weeks, hoping its just sensor related, will clean them again to be sure...
Had another look over the weekend, no visible leaks. Looking at the vacuum lines now, thinking that these may be either partially blocked or sucking in false air from somewhere. Looking at replacing as much vac line as possible with new hose given the age, plus new joiners and t pieces, preferably with brass fittings.

Did you ever replace your vacuum hoses? Any improvement? I'm also at the stage where i'm thinking of replacing vac hoses and solenoid valves.
Have replaced the soft rubber vacuum lines as far as i can reach. This includes from turbo air control valve to solenoid and from airbox, plus under manifold etc, and also under car from near starter motor. note that this does not include the hard plastic ones. Also replaced the t fittings etc as much as possible. Secondary solenoid is newish (replaced with new when turbo was done under warranty) , primary solenoid is new. Manifold o rings are all new.
No evidence of manifold splits, no oil mist or tracking of oil at top of engine. No evidence of oil leaks.
Cleaned MAF's and MAP.
Re-sealed EGR pipe flanges where they meet the egr valve, both were leaking. Checked EGR operation, both were smooth and i could feel the butterfly valve opening and closing with my pinky finger.
No airbox leaks or intercooler hose leaks that i have found, carried out smoke test, no sign of smoke anywhere, even with wide open throttle valve (engine off).
Fault code raised is P2263 when cruising along, low throttle input, low load.
Both turboes actuate properly under load.
Car is going into Dovers tomorrow for another check over.
Describes what I experience exactly, fault occurs under low load conditions either cruising along flats or descending.Quote:

Heat and time seems to be a factor. The fault never arises immediately. I have to have been towing for more than an hour before the fault triggers.
Please post up what Dover finds, even if it is nothing.
Found out today secondary turbo is the issue, actuator stuck or jammed. Getting pricing to replace tomorrow from Dovers.
Variable vane primary was replaced under warranty.
They reasoned they can spend 4-5 hours trying to free up the actuator and it may be ok for a while, or spend the same labour hours towards a new unit.
Considering its the original and done 196000km and countless millions of rpm, plus that i cant (or won't) sell the car without it being fixed, the only choice would be to replace. Rest of the car is still great and i have no intention to change just yet.
Is it the turbine or the compressor side? Mine had the turbine side control changed at 160,000km. Both turbine (exhaust) and compressor (intake) side of the second turbo are actuated closed to completely isolate it when not in use (for those not aware).
