So i have a few faults after clearing yesterday, could i please have some help with as many as possible as i would like to fix as many as possible, really sorry that there are so many.

Diesel Engine,
Glow plug device or relay
Egr control

Instrument pack
EBV function fault received from ABS ecu
instrument pack checksum incorrect.
Heating, Ventelation, Air con control module
Air quality sensor line fault
Ventelation fan PWM control voltage fault
Left seat temp sensor fault
Aspiration motor fault
Evaporator sensor fault
LV low error shifting gate fault
p0044
p00fb
p0066
p00c3
p0079
p00a8
p0087
p0082
p00fc
p008f
Security
Locking plate motor fault when locking
Immobilizer
Key 3 random code tolerance increased
Power steering
Driver door central locking mechanism short circuit
Wash Wipe
Internal hardware error
Headlights, Interior lights
Can't communicate
Light check module
ECU EEprom fault
Air suspension active/inactive
Right side marker defective
Left side marker defective
0094
0095
Steering column
Steering column radial motor blocked positive

 
can help with a few the EBV code ignore had that on mine and it dose not refer to the RR its a left over BMW system
key code tolerance also ignore its normal

a lot of codes maybe related, (air suspension etc) it maybe worth checking fuses etc if that fails then it could be down to unplugging units until something communicates take a look here

the page plus the following few will give you an idea of how the communication busses work on the l322
 
Hey Russel. That seems like a lot of codes! Did you do a scan then took then saved the codes then erase them and then scan again? You shouldn't worry about the intermittent ones that pop once in a while for whatever minor reason and then just rescan and focus on the present ones. :)

Clear the codes and scan again then that should fix quite a chunk :)

What did you use to scan?
 
I clears all the codes yesterday and these are what popes up today, I'll scan again tomorrow as I cleared them all today when I scanned, I'm using car soft i930 to scan
 
Diesel Engine,

Glow plug device or relay - probably intermittent if someone switched the ignition off while plugs were warming up worst case scenario the plugs need changing but it seems unlikely. What's the mileage and year of the car? Is it TD6? Any service history for the glow plugs?
Egr control - it seems a very generic diagnostic but EGR if it still works probably needs a clean.

ABS
Air suspension system can error (won't clear) - its strange that it pops up in ABS. When you start the car do you get AIR SUSPENSION INACTIVE message with the bong? Does it travel up and down when you control it? I had my pump reconditioned when I had issues. Sometime when I let the battery go flat or jack up the car the suspension goes into inactive mode but then few minutes of driving and it comes back to normal.

Instrument pack
EBV function fault received from ABS ecu - Probably triggered by the above.
instrument pack checksum incorrect. - Something out of sync here. Sometimes when the immobiliser parts are located in the instrument cluster it can have a counter such as keeping the same sequence of how many times you press the open and lock key and if you keep playing with the key outside the range of the car it can kick things out of sync but that should be erased and go away.

Heating, Ventelation, Air con control module
Air quality sensor line fault - In L322 you can set the automatic re-circulation based on the quality of air. I never use it personally but its there. Air quality sensor probably not sending the correct signals if its faulty physically but most likely once you delete it it won't come back - another little gremlin.
Ventelation fan PWM control voltage fault - I had an issue with my L322 fan speed and it turned out the resistor was on its way out. PWM stands for pulse width modulation which means you fan receives constant voltage but its speed is controlled by resisting the voltage flow. Does the fan blow at different speeds?
Left seat temp sensor fault - First need to asses it if its a present fault. Do you have a problem with the heated seat?
Aspiration motor fault - No idea at this present moment.
Evaporator sensor fault - Same here.
LV low error shifting gate fault - Dodgy gear selection P, R, N, D (?) should be intermittent code.
p0044 - All these codes I don't have time to lookup right now sorry. :)
p00fb
p0066
p00c3
p0079
p00a8
p0087
p0082
p00fc
p008f

Security
Locking plate motor fault when locking - I had to change the lock mech on my front passenger door any issues with locking the car? Mine would lock and occasionally unlock but most of the time it would stay broken.

Immobilizer
Key 3 random code tolerance increased - Playing with the key out of boredom :) Could trigger the checksum error in the instrument.

Power steering
Driver door central locking mechanism short circuit - Could be triggered by security. Either lose wires in i.e. door shuts or the door catch assy.

Wash Wipe
Internal hardware error - Too broad. Do you get screen wash when you press the button? My rear one has failed and it leaks if I want to squirt the rear window. If the front jets fail to dispense then maybe the pump?

Headlights, Interior lights
Can't communicate - Usually nothing smart about the light bulbs inside unless the convenience module (in some cars) is playing up. Does your RR come with lenses and HID or just standard headlamps? Usually with HID you got the headlamp wash and self leveling.

Light check module
ECU EEprom fault - Haha sounds severe but probably a random code unless the car is really in a bad way.
Air suspension active/inactive - Triggered by above probably just in memory unless the suspension is faulty.
Right side marker defective - I assume you don't live in america and you don't have the markers their day running light oldschool equalivent.
Left side marker defective - Read above.
0094 - Google unless the two of the above codes correspond.
0095 - Google unless the two of the above codes correspond.

Steering column
Steering column radial motor blocked positive - Does the electric steering column adjustment work? Up and down back and forth? I had an issue with mine as the plastic casing inside was snapped and someone already been there with zip ties!

Summary:

What's the history of the car? Have you had it for long? From the scan it sounds like it was stationery forever or something or a bit neglected.
Erase the codes then scan again and some of that should go away the rest needs to be diagnosed in detail.

I am not the most experienced person on here so take things with a pinch of salt but some of the errors only sound complicated and once you delete them they never come back. I wish you many of these!
 
ABS will go out in sympathy with the EAS...the two systems are linked and talk to each other regularly.....bit like my girlfriend and her mum!
 
Thanks for all the advice folks, managed to sort a couple of problems, found out that the internal hardware error was the headlight adjuster has completely broken so needs replaced so that can wait till i do the face lift conversion
