Symptom Chart

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

SYMPTOM	POSSIBLE CAUSES	ACTION
Exhaust leaking	Exhaust system leaking	Check the integrity of the exhaust system. Rectify as necessary
Exhaust excessively noisy	Exhaust system leaking Exhaust system fouling the body, transmission, etc	Check the integrity of the exhaust system. Rectify as necessary Check the exhaust system for foul conditions
Engine performance reduced	Air intake system fault Exhaust system restricted/blocked Fuel system fault Ignition system fault Engine system fault	Check the intake system for correct installation and damage. Rectify as necessary Check the exhaust system for restrictions and blockages. Rectify as necessary Refer to the relevant article of the repair information and check the fuel system. Rectify as necessary Refer to the relevant article of the repair information and check the ignition system. Rectify as necessary Using the Jaguar Land Rover approved diagnostic equipment, check the powertrain control module for related DTCs
Excessive smoke from exhaust	Gasoline particulate filter substrate is missing or severely damaged Gasoline particulate filter incorrect installation Gasoline particulate filter failure	Remove the gasoline particulate filter and visually inspect for missing substrate, severe damage and correct installation Check and install a new gasoline particulate filter, only when diagnosed as failed
Poor acceleration and lack of power	Gasoline particulate filter substrate is missing or severely damaged Gasoline particulate filter incorrect installation Gasoline particulate filter failure Gasoline particulate filter is getting full of soot Connector is disconnected, connector pin is backed out, connector pin corrosion Differential pressure sensor hoses for crushed, blockage, split Charge air system leakage Blocked air filter Gasoline particulate filter hose lines disconnected Differential pressure sensor mechanical integrity Exhaust system leakage upstream of gasoline particulate filter. Gasoline particulate filter is getting full of soot Gasoline particulate filter partial blockage Inhibited regeneration - Unable to reach good conditions to regenerate the gasoline particulate filter Customer driving routine does not allow the system to clean the gasoline particulate filter	Remove the gasoline particulate filter and visually inspect for missing substrate, severe damage and correct installation Check and install a new gasoline particulate filter, only when diagnosed as failed Using the Jaguar Land Rover approved diagnostic equipment, carry out the service regeneration procedure Inspect connectors for signs of water ingress, and pins for damage and/or corrosion Check gasoline particulate filter pressure sensor hoses for crushed, blockage, splits Check charge air system for leakage Check air filter serviceability Check differential pressure sensor for mechanical integrity, split pipework, loose hose clips and damaged hoses Check gasoline particulate filter system for mechanical integrity Refer to the gasoline particulate filter regeneration procedure and carry out a gasoline particulate filter regeneration Advise customer of driving routine required to regenerate gasoline particulate filter as stated in the vehicle handbook
Engine speed restricted	Gasoline particulate filter substrate is missing or severely damaged Gasoline particulate filter incorrect installation Gasoline particulate filter failure Connector is disconnected, connector pin is backed out, connector pin corrosion Differential pressure sensor	Remove the gasoline particulate filter and visually inspect for missing substrate, severe damage and correct installation Check and install a new gasoline particulate filter, only when diagnosed as failed Inspect connectors for signs of water ingress, and pins for damage and/or corrosion Install a new differential pressure sensor, only when diagnosed as failed
Fuel consumption high	Gasoline particulate filter is getting full of soot Charge air system leakage Blocked air filter Gasoline particulate filter hose lines disconnected Differential pressure sensor mechanical integrity Exhaust system leakage upstream of gasoline particulate filter. Gasoline particulate filter is getting full of soot Gasoline particulate filter partial blockage Inhibited regeneration - Unable to reach good conditions to regenerate the gasoline particulate filter Customer driving routine does not allow the system to clean the gasoline particulate filter	Using the Jaguar Land Rover approved diagnostic equipment, carry out the service regeneration procedure Check charge air system for leakage Check air filter serviceability Check differential pressure sensor for mechanical integrity, split pipework, loose hose clips and damaged hoses Check gasoline particulate filter system for mechanical integrity Refer to the gasoline particulate filter regeneration procedure and carry out a gasoline particulate filter regeneration Advise customer of driving routine required to regenerate gasoline particulate filter as stated in the vehicle handbook
