Air Suspension Diagnostics & Repairs in Sunbury-on-Thames
Air suspension delivers a superb ride, but it relies on airtight springs, a healthy compressor, valves and sensors working together. When one part fails, the car can drop, the compressor can overwork and warnings appear.
We diagnose and repair air suspension on Land Rover, BMW, Mercedes, Citroën and other vehicles where fitted.
Safety first: A vehicle sitting on its bump stops can handle poorly. If the suspension has dropped significantly, avoid driving and contact us.
Common signs
Symptoms worth checking

How air suspension systems fail
Air springs perish and leak, pipes and valve blocks can leak, compressors wear out — often because they’ve been overworked by an existing leak — and height sensors can fail.
Replacing a compressor without finding the leak usually leads to another failure. That’s why we locate leaks first.

FAQs
Air Suspension: your questions answered
Why does my car drop on one corner overnight?
Usually an air leak at that corner’s spring, pipe or valve.
Why does my air suspension compressor keep running?
It’s likely compensating for a leak, or a sensor/valve fault. Overworking the compressor shortens its life.
What causes an air suspension warning message?
Leaks, compressor faults, height sensor issues or valve problems. We read the codes and test.
Can you diagnose air leaks in air suspension?
Yes — we test springs, pipes and valve blocks to locate them.
Do you repair Land Rover and BMW air suspension systems?
Yes, along with Mercedes, Citroën and other systems where fitted.
Is it safe to keep driving when air suspension has dropped?
It’s not advisable. Handling and clearance are affected and further damage can occur.
