If you disconnected the battery then the valve blocks are closed and the system won't try to keep the vehicle level. So one corner going down means that the leak is somewhere between that corner and the rear valve block.

By disconnecting the battery you're taking the compressor and air reservoir out of the equation (provided that your valve blocks are sealing correctly).

But yes you can access the compressor under the passenger side rear door, if you put the car in off-road height and pull onto the kerb you'll have plenty of space to access the compressor.

thanks. That's what i thought but wanted to be sure. need to wait for it to stop raining. Seems i also now have a fuel leak..... which the garage who carried out the service assure me it is not because of them doing the service.
somewhere at the back of the engine but they need to remove the windscreen wipers and the black masking to have a better look. 2019 RRS P400e Autobiography

Was it leaking before they did the service ?

It could be that they fuel filter is leaking (which may have been changed during the service and not refitted correctly), that's located under the vehicle above the front skid plate.

Wasn't leaking before, which is why i presumed it was first an oil leak.
Expected nothing less for them to say that it wasn't their fault.
I seem to recall the fuel filter was changed.
Really wish i had a place to tinker on the car and some suitable equipment to raise the car up.
Is the fuel filter easy to re-adjust, or does it need a 'pro' to do it?

If you put the car in off-road height and then jack the front up a little you should have enough room to get underneath and check the filter.

You will need to remove the skid shield, it's a pretty heavy lump when you're laying on the floor!

Alrighty. No torrential rain so went out and took the plastic cover off under the left hand rear passenger seat.
Didn't find i was expecting to.



Is the drier unit then located somewhere else or am i being a muppet.
Couldn't see the same set up as posted in other posts and the sites selling those. 2019 RRS P400e Autobiography
