Wife was coming up a hill and this happened. went back to normal and she got home ok. Codes: P22D2 - turbocharger turbine inlet valve stuck open P22CF - turbocharger turbine inlet solenoid circuit. Live data showed, as far as I can tell, the turbine inlet valve was closed. So, where is the Sep 7, 2008. #1. When I bought my new Discovery 3, almost 3 years ago, I didn't realise that having an automatic gear box would mean that the car would choose a gear it fancies and stay in it for some time. The other week I drove from North to South and the blighter was stuck permanently in 3rd gear. I suppose it could have been worse. None of this solves the problem but I 'll offer a couple of suggestions: 1. Make sure the coolant system is fully bled. 2. Make sure you have no coolant leaks, check the plastic bleeder valve under the engine cover. They are plastic and do go bad. 3. Make sure you have no intake leaks and have good crankcase breather valve. I found that the cable was screwed fully in to the actuator shaft. Looking at the manual it states that the cable must be screwed into the actuator shaft 5 full turns only, that was causing the jam. Decided to remove the motor/gearbox and found one of the nylon gears was stripped, luckily I had purchased a spare set. The engine now responds from about 1500rpm rather then the 2000+ rpm as it was before. With a roof rack fitted on a recent trip to Vryheid and back we averaged 10.2lt/100km on the way down and 10.5lt/100km on the way back (uphill). This in comparison of between 11.7 and 12.5lt/100km before without roof rack fitted. DPF Cleaning on Land Rover Discovery 5 cause for DPF fault is related to the turbo fault.common issues with turbo Overboost on these vehicles with 3.0 TDV6 i This problem only affected early Discovery 4 TDV6 models from 2010 to 2013 in the VIN range AA510178 to DA676456, along with Range Rover Sport and the 2013 Range Rovers that used the same TDV6 engine. The problem was subject to a Land Rover Technical Bulletin issued in 2013, and then a later bulletin LTB00487V6 issued in 2015. But this was only 2005 D3 2.7 TDV6 - High Pressure Fuel Pump. Hi Guys, Only just bought the D3 but already had some issues, managed to fit a new thermostat housing myself (sits under the inlet manifold) but now have a new issue. Garage computer reporting low fuel pressure, symptoms are (upon acceleration) a message about engine control followed by special GXCwbBR.
