What is the state of the battery?

put a new one on it still got all these issues

Is the new one fully charged and reading >12.6v?

kermit_rr · Dec 23, 2023

Could well be some codes that need clearing if the battery has gone flat, make sure it's on high range, try a cycle between hi and low and back again

If it's running then you can drive a few feet with low then hi selected a few times. Or, can you not select either?

You say suspension is hard and wont raise or lower, you sure its not down on the stops?

Break it down into bits of problems that may well not be related.

Clunks can be suspension bushes.
Suspension issues, compressor?

That’s a good approach - one problem at a time.
Maybe get the gears sorted first?
As Kermit says, drive a few feet and try selecting various gears / low / high a few times…?

Gearbox is a separate issue and its probably ~~knackered~~

Needs a fluid change? first.

but why wont the up down work to raise suspension
why the gearbox issue

best to figure exactly what the issue is before asking why

Run it for long enough for the compressor to fill the tank. Then try steering lock to lock before changing heights.

Do you have a tape measure, center of wheel to top of wheel arch. What is it?

Cos you have a problem.

Not yet but we all know they are not the best.

12.6 volts, that is not fully charged.

"Battery is good". What voltage do you have? These cars are very voltage critical.

No it's not, but anything over 12.6 is a starting point that should be sufficient to not cause immediate low battery errors.
In my opinion it's just as important to check what voltage the battery drops to during cranking

Plus is several ECUs are getting ready for take off, then that will put significant load on the battery and drop the reading

That is why if the voltage is on the low side to start with, you are rapidly in trouble.
