Engine management light stays on

p1396 is a engine managment code. variable valve timing solenoid b malfunction, not a gearbox code. you really need to take your car to someone with access to suitable diagnostic equipment to help sort this problem out, hope this helps,

Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

Hello
When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

you need to read the code thats coming up...

If the Dianosis test Code P1000 is flagged after DTCs have been cleared, all engine management OBD diagnostic monitor drive cycles HAVE NOT BEEN COMPLETED. See http://www.bluejag.co.uk for further details on this

It shows that your fault management system has been recently reset. It will not bring on the engine management light. For more info on fault codes goto

Check the fluid level in the gearbox firstly.

Other 2 things it could be are the torque converter or slave cylider for the clutch.

Most likely it is the torque converter as the engine light is on aswell. although these may not be related. you will need to get it on a code reader, diagnostic machine to be sure.

i have x-type 2.0D 2004 last couple of weeks the engine management light has been illuminated i took it to my regular mechanic who did a dianostic check and found it to be the air flow meter which he replaced and the code was cancelled a day later the light came back on again, so i took it back he took another reading and it came back as the same fault so he cancelled the code again, but the light has come back on and although this is annoying it hasn't deteriorated the performance

p1647 is linear o2 sensor control chip bank 2 p1111 is intake air temp sensor

You need to take to Jaguar technician to have Mil lamp codes read and cured the restricted performance is the engine protecting itself as there is a fault in the management system,usually fuel system related,It has gone into "Limp Home" mode to try to limit the damage done untill the fault is cured
