Q&A:

Q1: Will replacing the bellow fix rear sagging or overnight lowering?
A1: Yes, if the sagging is caused by a leaking bellow. Always confirm no leaks in the air line and ensure the compressor is performing correctly.

Q2: Do I need to replace both rear bellows together?
A2: It is recommended, since if one has failed, the other is likely worn. Replacing both restores balanced suspension performance.

Q3: Is any coding required after installation?
A3: No coding is typically needed. The vehicle will self-level after start-up, although a professional calibration is always beneficial.

Q4: Does this come with new fittings or an air line?
A4: This product includes the air bellow only. Reuse your existing air line and mounting hardware unless damaged.

Q5: How do I confirm fitment?
A5: Match your VIN and original part number to the references listed above. This bellow fits W164 ML-Class models with rear Airmatic suspension.
