Another EAS fault thread!

[Clabs]

Hi folks

I am looking for some advice regarding an EAS fault on my 1999 4.6HSE. The car actually developed this fault earlier this year but unfortunately, I too developed a serious fault so the car has not really been looked at whilst I recover.

Originally, the car was taking a LONG time to reach normal height with the compressor running a lot and being quite noisy. I replaced the seals in the compressor and the car then (and still does) reach the desired ride height quite quickly though nowhere as quick as when I bought the car 10 years ago.

The problem now is that when I switch the car off, the car sinks down quite quickly. It doesn't sink straight down like all the air is being dumped in one go through a leak - it drops in about 5 small stages, stopping each time for about 5 seconds. When the car is dropping there is some clicking going on from the valve block/compressor area, and when that clicking stops, the car stops dropping.

I have checked around for any obvious leaks and cannot find any but to my mind, it seems like the valve block is receiving spurious commands to tell it to lower the car.

Any ideas where I should start looking? All the other faults I seem to read about revolve around failed compressors and general leaks.

Any help much appreciated.

Best regards, Mark

You've got a leak.
The extra work to overcome it has shagged the compressor and will do for your new seals unless you sort it.
When you park up the car tries to self-level and that's what the clicking noise is, the solenoids in the valve block being opened to release air to try to self-level. However with a leak, probably in a bag, the system is chasing the leaking bag downward.

Stick a location into your details, there might be a helpful Rangie owner close by, a decent cuppa and decent biscuits can buy a lot of help.

or just read Wammers 'how to' at the top of this section.

Thanks for the reply buddy - and that makes a lot of sense to me.

I shall stick my location (Watford) into my details because I have a feeling I am going to need some help as I am not allowed to be lifting anything much at the moment so even taking a wheel off is a struggle now the kids have gone back to uni

Thanks very much for your help and also the pointer to Wammers how to.

Cheers, Mark

It's a pleasure.
If you remove the EAS delay relay (tall one under the passenger seat) that stops the self-levelling so the corner with the leak should sink alone and narrow down your search.

Love to help you (other people's biscuits always taste better) but you're a bit too far away.

Mate -thank you and what a great tip. I shall try that tomorrow morning. My betting is front right corner as that is slightly slower than the rest of the car.

Shame you are so far away as biscuits, bacon rolls and "proper" tea are a speciality here

Dogsbody has given you the answer. If your airsprings are 10 years or more old they will all need replacing, the have a design life of 7/8 years 80K miles.
