i just purchased front arnotts and was told i may need shock mounts.... anyone know where i can get the mounts?

 

The only replaceable "shock mount" on these air suspension units is at the bottom, the tops mount direct to the suspension towers. Fronts are mounted in the lower lateral control arm, and rears at the bottom of the air unit itself. Cost is low at around £20 (=$32), but labour to swap out is quite large due to the dismantling work needed

 

Would u have a part number or maybe can lead me in the right direction for this? Thank you sir

 

Here you are: -

Rears

S-type suspension shown hence the steel spring, but the bush is the same

Fronts
Jaguar S-Type, X150, X350 Front Lower Damper Bush (fits into straight wishbone arm) (C2C36866) | JustJagsUK.com=

 

I locate all my parts with Google.

 

thanks I purchased them... should have new front shock bushings and new arnotts installed by next wk ... !!! can't wait to see what it feels like...

 

Keep us updated, hope it works for you

 

well had the shocks installed along w the bushings and was told yesterday that the compressor isn't turning on .. Wondering if it needs to be reset or something?

 

I'm going out right now, but will look at my technical notes when I get back and get back to you. See my other post too on what switches the pump on and off.

 

OK, I've now had a chance to look at my notes and the following are the main points: -

- Nominal operating pressure (of pump) is 15 bar. A pressure limiting valve maintains a minimum pressure of 3 bar in the system to protect the air springs
- A pressure relief valve is provided and set at 17.5 bar to exhaust high pressure air to atmosphere to protect the system. (presumably if something goes wrong and pressure buklds up too much)
- reservoir pressure is maximum of 15 bar and is controlled by the ASM; volume of the tank is 4.5 litres
- compressor should charge the reservoir in 2 minutes
- at maximum pressure, the reservoir is capable of one complete lift of the vehicle
- system operates within a defined pressure range (not quoted), but normally keeps pressure above 9 bar.

So it seems the reservoir pressure can vary between 9 and 15 bar. If the car appears normal height, and you have no fault code or message, it would appear the reservoir has enough pressure in it so has not needed to turn on the compressor (yet !)

Hope this helps.

 

There's more !!

System can either use the reservoir to raise the vehicle, or the compressor. The reservoir has a close-off valve to retain pressure. This is opened when a raise is needed.

I suppose of there is sufficient pressure in the reservoir to raise the vehicle after spring replacement, the compressor will not be turned on, but the notes don't give a full description of the processes.

 

Speed is a consideration as well. According to the documentation, in most circumstances if the system is running normally the compressor shouldn't try to come on until the car goes over 25mph. One situation where it will is if the 'vehicle too low' warning message is being displayed.

Has the car actually been taken for a run or is it sitting in the workshop?

 

Speed is indeed a consideration. Apologies, as I didn't read enough of my notes. The air suspension has 5 customer modes, (plus a dealer transportation mode): -

1. Sleep mode - compressor inhibited
2. Preliminary mode - compressor inhibited
3. Post mode - compressor inhibited
4. Stance mode (engine running, car stationary) - reservoir used to raise vehicle if necessary, unless reservoir pressure is low, or vehicle is below minimum height, then compressor is started
5. Drive mode - applies above 1 km/hr. Above a certain speed, the compressor is used to raise the vehicle height and replenish the reservoir, (but this speed is not specified)

 

car hasn't ben driven yet but I have relayed the message to him from you and am awaiting a reply back from him tomorrow... I miss my car although my dads s550 has been a nice daily driver the last 3 wks.... This Benz is amazing but I still want my car back...

 

******FIXED******* turns out the pump needed to be reset by computer.. It's up n running now . Just waiting 'till tomorrow for some quality control and I should have her back........

 

Good for you , it's better than replacing parts

 

Very pleased to hear your car is now fixed, but puzzled at the time taken (4 weeks ?). What has taken place in that time ?

 

Well the thing is this . I dropped off the car at my cousins BMW dealership so he really hasn't been putting in a full days work on it. Basically been working on it after work.. Also he went over the ENTIRE car for me. I know 4 wks is a long time but my bill for all the work and labor is ZERO !!!! Im gonna throw him a 200$ tip but other then that theres no charge !!!! So the wait for me was no big deal... Plus I have enjoyed driving around in my dads s550... Benz is a beast !

 

I can also recommend a suitable Scottish malt whisky, like Talisker or suchlike.

 

LOL, lucky you , I waiting for my Benz too
