L322 Heater Fixed and Suspension question

Just to provide feedback. Heater stopped heating over Xmas. Fix was to replace valve at back of engine. All good and warm again. not expensive fix.

Quick question - after work was done I notice the it is sitting down on the suspension when not driven for a couple of days. I did not notice this perviously. Is this a symptom of potential air bag leak or something else. Once she starts up and is running suspension lifts to normal ride height. Any insights welcome.

Its a 2007 TD8 with 180k miles.

Time to get airy with the fairy (liquid)

Probably bags, any history of replacements?

The upper front suspension air bag seal rotates with the bag when turning peculiar design, which after a while WILL!! leak..

Best climb under her like Myfirstl322 says a bottle of fairy liquid and a spray bottle.

Also if they're original bags at that mileage expect general rubber fatigue as a factor aswell.

No fault codes???

No fault codes and I'm a bit lost with the fairy liquid story - is that to test for air leaks?? the rear offside bag was replaced a few years ago. I just thought it was unusual that after having a bit or work done it started to sit down in the rear? Not completely dropping but approx 3 inches I'm guessing.....

Soapy water will bubble when it hits an air leak, clearly showing where said leak is located

She should stay level..

Check the nearside bag, if the off side was changed through wear the near side wont have been far behind, it is normal to change in pairs we, have seen it so many times one goes and the other follows.
