Hi Guys.
I have a 2011 C5 X7 2.0 HDi with the engine management light on
A quick check with my USB code reader reveals P2084
Could this be a sensor - any one else had this issue ?
I had given it a run down the Motorway in the hope that it might clear - but no luck

Re: C5 X7 Engine Management light
If you have the DW10CTED4 engine, it will have the Delphi Injection system. That code is detailed below:
So on the basis of this code alone, it would seem your gas temp sensor is either faulty, or the electrical connections are. I will need your VIN to confirm this, as there's only so far the crystal ball can see.
If it is the sensor that is faulty, here is all the info you need (pending VIN for confirmation)
Fault Code | P2084 |
After sales description of the fault code | Particulate filter upstream gas temperature sensor: Voltage variation outside the tolerance |
Description of the diagnostics |
|
Conditions of activation of the diagnostics | Engine running |
Conditions of disappearance of the fault | Driving with the engine hot for 5 minutes |
Down-grade modes if fault present | Deactivation of the request for regeneration of the particle filter from the diagnostic tool |
Switching on of the warning lamp and/or warning message | Warning lamp MIL |
Main customer complaints likely | No effects immediately perceptible to the customer |
Suspect areas |
|
If it is the sensor that is faulty, here is all the info you need (pending VIN for confirmation)

Re: C5 X7 Engine Management light
Don't worry about your vin post. The forum software "knows" a vin has been posted and obscures it so that it is hidden from general view. The Mods and Admins can see it though.

Re: C5 X7 Engine Management light
Hi, I own a Citroen C5X7 MY11 HDI Vin VF7**************[VIN obfuscated, can be read by forum staff] - Also the ENGINE MANAGEMENT warning light is constantly on. Have disconnected the batt for a hour and when restarting it still comes on. It all sounds ok, nothing that I can hear or see is wrong. What could the problem be ?

Re: C5 X7 Engine Management light
You will need to get it diagnosed with Diagbox. There are any number of engine control system, emissions, or air & fuel faults that can bring this light on. There will be one or more fault codes active, so we need this to be able to help.
