I have a 2010 L322 4.4 TDV8 Vogue Se.
This is weekend I took the vehicle green laning and unfortunately my Front Passenger suspension had a leak causing the compressor to overheat and the complete suspension dropping to bump position showing a 30 mph limited.
Not something you need while doing strata florida in Wales.
Anyhow the question is should I replace all sir bags as preventative maintenance or is it OK just yo change the faulty one?

Any advice would be appreciated

You could just replace the bag and possibly the other side too as its condition won't be much better but if the shocks are well-worn then best to replace both assemblies, not just 1 side. The rear bags don't have the same issue as the fronts but if fitting new front asemblies then you'll most likely feel that the rear shocks also need replacing.

Are you sure it's the air spring as it could be the air hose, joint or valve block that's leaking. 2012 TDV8 Vogue (L322)

No not really sure where it is leaking. All i know is that you can hear air coming out worse when on off road height.
How can I check if its the bag or hose?

Thanks for the info. If I need to replace I will replace both fronts first and see how it is.

Just spoke to one of the guys who said he could feel the air coming out the back so he think its the Air spring.

Sprayed soapy water will show leaks from the airsprinng.
