We Don't Guess. We Test.
Most shops use the "Parts Cannon"—guessing at the problem and replacing expensive components at your expense until the light goes off.
At Kanewske Motors, we believe in Root Cause Diagnostics. Whether it's a corroded wire on a Porsche or a stuck valve on a Bentley, we use factory-level tools and forensic testing to find the exact failure.
Below are real examples of cars we've saved from the dealership crusher:
Case Study: Saving a Bentley Mulsanne Owner $18,000
Two Bentleys in the shop simultaneously for air suspension and electrical diagnostics
The Problem: A local customer brought in a 2014 Bentley Mulsanne. The vehicle had collapsed on the left rear side, making it undrivable.
The Dealer Quote: The franchise dealership quoted $22,000.
The "Parts Cannon" Approach: They wanted to replace the entire suspension architecture at full list price. The customer felt trapped.
The Kanewske Diagnosis: Instead of just reading the error code, we performed a surgical diagnosis of the pneumatic system.
Visual & Soap Test: We confirmed both rear air bags had developed micro-leaks due to age.
Component Testing: Further testing revealed the solenoid valve block had stuck open, and the air suspension compressor was burned out from overworking.
The "Smart" Fix: We didn't need to buy Bentley-branded boxes to get Bentley-quality results.
Sourcing: We sourced high-reliability OEM-equivalent air struts, a new valve block, and a heavy-duty compressor for under $1,000 in parts.
Execution: We replaced the failed components, calibrated the ride height sensors, and performed a nitrogen fill to ensure the system remained moisture-free.
The Result: The Mulsanne is back on the road with a fully restored suspension system.
Dealer Price: $22,000
Kanewske Price: $4,000
Total Savings: $18,000
