I plugged my Lynx Evo into my 2002 L322 4.4 V8 Petrol L322, Wish I hadn't now.
The list is pretty long.
My car has not had diagnostics plugged in since before the battery was changed, so I believe a lot of these are because of the old battery being weak.

But if anyone could explain the cause of the more obscure ones I would be very grateful please.

The HVAC fault came back after I deleted it. And the gearbox fault came back. The pasenger seat occupancy sensor will come back when someone eventually sits in it again. But the one that has come back that confuses me is: left water valve driver fault.

After a drive out I plugged the diagnostics back in, and got these readings (Live readings).

Any problems with the car/functionality? Any lights on dash etc. ? .

Here is a list of faults I know of function wise.

Slight blow from the right hand catalytic converter.
Gearbox goes into limp mode after about 25-35 minutes. (Already had a new radiator, Solanoid B changed and new oil fitted).
Front drivers side suspension takes a long time to think about raising when the rest of the car does it straight away. But it goes up fast. Just the time it takes to think about suddenly doing it.
The suspension will lower and raise to standard road height fine, but will not go into off road height. No fault codes coming up for this.
Seems to have plenty of power, when the gearbox is working before limp mode, it changes perfectly, I know the front passenger headlight dipped beam light goes out after a while at night so a new ballast is required.
And the heating and air con seem to work fine despite the fact there is a fault keeps logging for it.

There were lots more faults before I changed the battery, after changing the battery, the car's behaviour changed for the better.

the water valve fault could be something to do with the heating valves, there is one for each side which restrict/permit the amount of coolant getting to each side of the heater matrix.

if one is stuck then you may get a fault popping up, do you get controllable temperature on both sides of the cabin? There is nothing that can't be fixed with a hammer😜😜

Gearbox Problem:
Suggest make a separate post about just this and hopefully gearbox guru RRPhil will come along with advice. Do you mean transmission oil cooler or main radiator replaced?

Air Suspension:
Have you calibrated the heights yet (493mm front, 483mm rear from wheelarch metal to centre of hub), probably needs to be reset before further diagnosis. Any history on the compressor? Usually a replacement resolves most issues. What is the reservoir pressure reading - should be @ 180 psi +?

Should be able to get the cat welded up? .

I'd clear them all and then see what returns. Ron B. VK2OTC

Main radiator replaced. Second set of images are screen shots after the codes were all cleared and the car had been driven twice. Gearbox is due to be fully refurbished in a couple of months if I don't get a newer Range Rover then.
