P0030 with the engine light on, from a Land Rover bulletin

Supported by vehicle data

Land Rover bulletin LTB01191NAS1 says the engine light may be on with P0030 and another code stored in the PCM on 2016 to 2018 Discovery and Range Rover models. We only read the NHTSA summary, which does not say what the fix is. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.

• P0030: Oxygen sensor heater circuit fault on bank 1 sensor 1

P0089 from a relief valve seal in the in-tank fuel pump

Supported by vehicle data

Land Rover bulletin LTB00623NAS1 links P0089 with the check engine light on 2012 to 2013 Range Rover Evoque and 2013 LR2 to an over-active relief valve seal in the in-tank fuel pump. The bulletin says there is no noticeable engine issue, so a light with no drivability problem fits this pattern. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.

• P0089: Fuel pressure regulator not holding the pressure the computer asks for

P008A from engine software calibration

Supported by vehicle data

Land Rover bulletin SSM72531 links P008A with a warning light, rough idle, hesitation or loss of power on the 2012 to 2015 Range Rover Evoque to engine computer software, and the fix is a software update.
