What does management light on 2005 xtype deisel

You need to have the engine management computer scanned for faults and a test ride with a mechanic to show him or her the symptoms

burning bulbs can be the earth wire to the bulb. can also be baddle made bulbs... is it just your head lights no other electrical problems...

Get the codes read. Most auto part stores will do it for free. That will lead you in the right direction

Go to your local service station and have the DTE code read. Most can do this not just Jaguar. Have them give you a full list of codes then you can look up the problem here http://www.bluejag.co.uk/diagnosticcodes.php

does it have a particulate filter fitted on exhaust[ cat for deisel]
if not its your egr valve

the most common cause of that prob with xtype diesel is the hose going to the intercooler splits and leaks or the jubilee clip on the intercooler has corroded and broken allowing the hose to blow off not easy to get to to repair

If I am understanding your post, I believe you do have a levelling
system and it should be near your light switch on the dash. It is
the type of switch that you depress first, it then springs out and
you turn the small knob (just like your instrument panel lights
adjuster next to it.) What you do not have perhaps, if your car is
not fitted with HIDs (high intensity headlamps), is the automatic
levelling system which is a legal requirement when HIDs are fitted
due to the high power of the lights....

if you don't have a self-levelling system then you'll have a manual
system, operated by a knob under the light switch so that you can
adjust to compensate for a heavy load in the rear of the car.

pump may need recalibrating or a kit through it
or you may have a cracked turbo

The car will need to be put on a diagnosic machine to point out exactly why the engine has gone into limp mode, but if it is still running it could just be down to a sensor, Hope this helps
