Hello to all,

I recently removed my car from winter storage. Prior to storage I put front jacks on the front end to prevent the car to sag and drop completely during it 5 months storage.( I disconnect the battery) I don't really jack the front up, just put a block of wood that just snuggles against the jacking points, I.ve done this every year since I own this beauty. When I remove my car from storage , I start her up, front end raises up just enough to remove the 2 blocks and off we go.

This year however when I started her up I got a vehicle too low message , but disappeared after the compressor started and went to correct height.
Now I've noticed that when my car is parked overnight I notice that the front end is sagging. I start the car but no "vehicle too message" message , the front end raises up eventually . I have to say that its been kind of chilly at nights here in Montréal, Canada, maybe this has something to do with it?

Any suggestions on probable causes and what I should look for? I hate seeing my front end sag.

Thanks a million to all.
Enjoy your day!

 

Sounds like you have a slow leak at the front on one or even both air springs. It could be the air connectors or the top inner air seal. Normally if it is the main spring diaphragm, the leak is more pronounced, and often the diaphragm just lets go big time. It may be time to go round with a can of leak detector and see where you get bubbling. My money is on a top seal, or maybe where the air line connects to the air spring.

 

The air suspension on these cars are susceptible to cold climate, meaning that the front end will lower over night due to basic science of cold air contracting. Do you get any other warnings?

 

Thanks for the help, I haven't had any warnings whatsoever. I will take a wait and see attitude with this issue, its probable the chilly nights and mornings as you say. will keep you informed.

 

Thanks for your reply, I did a little test yesterday afternoon. after viewing some YOU TUBE videos on suspension issues on these Jags, I started the car, and sprayed some soapy water on the air line that screws to the top of the Bilstein strut, this is found in the engine bay , one on each side. To my surprise the passenger side had some bubbles appearing from the brass bolt that screws the hose onto the nipple from the strut. I attached a picture of the strut. I am talking about the brass connecter on the upper part.

What should I do now?

 

My first response was it's normal since mine does the same thing in cold climates or if it sits for weeks without starting. Then I read on and saw you found a leak.

Keep us posted on if there is a fix or if you have to replace that shock/strut.
