Quote audit
Agent quoted $3,000 for Mercedes air suspension — what to check first
2026-05-06 · 4 min read
A $3,000+ air suspension quote is not automatically wrong. But it should not be accepted blindly, especially if the car only sinks overnight and still drives normally.
Owner takeaway
Do not approve a major repair from a vague symptom alone. Ask what test confirmed the failed part, then compare itemised quotes.
First question
Ask whether a leak test was done. Which corner dropped? Did they test the valve block, air line and bag separately?
Second question
Ask for proof. A photo, video, scan result or pressure test result is better than a one-line quote.
Third question
Ask if a cheaper confirmed fix exists. Valve block leaks can look scary but may not require changing full struts.
When to approve
Approve the expensive repair only when the failed part is identified and the quote is itemised.
