If both codes are displayed, check the following components common to both banks: Distributor cap Rotor arm Coil Electrical connections Pick-up (air gap) Amplifier Injectors (if code 34 or 36 is displayed) If either fault code 40 or 50 is displayed check components applicable to the particular bank that the misfire has occurred on. Land Rover Code U3000-43 I have a land rover discovery sport 2015 showing this code,the dealer has emailed land rover assist and to date they are replying to their emails saying they are looking into it (3 weeks),has anyone come across this code please. Land Rover Diagnostic Fault Codes List. P0001 fuel dosing, regulator control circuit, open circuit. P0002 fuel dosing, controller control circuit, unstable signal. P0003 fuel dosing, control circuit for the regulator, short to ground. P0004 fuel dosing, regulator control circuit, short circuit to positive. P0005 shut-off solenoid valve, open My 2007 Land Rover lr3 hse v8 is trapped in limp mode. It appears to start fine and drive great prior to this starting. There are no check engine codes only fault codes. I used my carsoft to detect what codes are present but no luck diagnosing because they seem generic. RLM (ride level control module) has 6 fault codes. P0462 normally indicates a fuel level anomally. There are many things that could cause that code to appear and a diagnostic is needed (assuming addressing the P1453 issue doesn't solve this one). This is an older thread, you may not receive a response, and could be reviving an old thread. Make Model: Land Rover. Discovery Sport 2.0 SD4 HSE Dynamic Lux SUV 5dr Diesel Auto. Mileage: 30277. Registered: 11/2017. Whist out driving on Saturday we experienced a “critical warning” message appear on the message centre. The car then displayed a “restricted performance” message and immediately went into limp mode. Working on 2006 LR3, intermittent no start, intermittent warning symbols. Has Comm faults in multiple controllers, only hard faults in BCM. B1b02-28, Low Frequency Coil, and B1c57-14 Passive Start Ignition Relay Coil Circuit. (will not clear). Have cut splices under passenger threshold and found no evidence of corrosion, no apparent water So I called Botzons Auto in the Spokane Valley 1-509-928-4747, they work and is certified on all European autos and have vast knowledge of Land Rovers, told them the issue and I have a appt for this Wednesday for the diagnostic. I think that the fault codes need to be cleared because the compressor works then shuts off. We will see then. It seems that the valve has been sticking to some degree for quite some time. MY12 RRV 4.4 TDV8 AB, +LLAMS, +e-diff, +ACC stop/go. Produce LLAMS for LR/RR, Jeep GC/Dodge Ram. My Disco 4 3L TT also hit Reduced Performance mode recently with fault P22D2-77 logged, which translates to "turbo actuator stuck open". It's easy to locate, it's attached directly to the fault code display under the seat. The display unit is removable ( just slide the unit up off of the bracket) and follow the cable that is attached directly to the unit (about 1 ft.in length) where it will be tangled with a mess of wires under the seat. It's the only cable that is attached to JpfR.
