Quick Answer
This hose is the right fix when a W176 A-Class or W246 B-Class with the M270 engine shows a boost or air leak at the intake manifold connection, such as a hissing sound under load, a lean fault code or reduced power. A tested used Genuine unit suits owners who want the original Mercedes-Benz fit and material at a lower price, backed by the warranty stated in the quote. Brand-new original and brand-new China-made hoses are also available for owners who prefer those options.
Diagnosis and Common Symptoms
On the W176 and W246 with the M270 engine, the manifold air intake hose carries pressurised intake air to the intake manifold. Rubber and plastic sections of this hose face constant heat cycling, pressure pulses and engine bay oil vapour. Over time the hose can harden, split or lose its seal at the clamp or connector. Unmetered air then enters the system or boost pressure escapes before it reaches the engine.
Common symptoms:
- Hissing or whistling noise from the engine bay when accelerating
- Loss of power, flat acceleration or limp mode
- Check engine light with lean mixture or boost-related codes (for example P0171 or P0299, depending on where the leak sits)
- Rough or unstable idle
- Higher fuel consumption than usual
- Oil film or residue around the hose joints
- Visible cracks, swelling or a soft, collapsing hose when inspected
A proper diagnosis should include a visual check and a pressure (smoke) test, because a leak at this hose can look the same as a leak at the charge pipe, the intake manifold gasket or a vacuum line.

Frequently Asked Questions
What symptoms point to a faulty manifold air intake hose on a W176 A-Class or W246 B-Class?
A failing manifold air intake hose on the W176 A-Class or W246 B-Class (M270 engine) usually shows as a hissing noise under acceleration, loss of power or limp mode, a rough idle and a check engine light. Lean or underboost codes such as P0171 or P0299 can be stored when the hose leaks air. A smoke or pressure test will confirm whether the hose is the leak point.
How do I confirm this manifold air intake hose fits my W176 or W246?
The Mercedes-Benz W176 and W246 manifold air intake hose is matched by part number, not just by model name. Compare the number on your existing hose, or the number from your car's parts catalogue, with the number in the Part Numbers and Fitment section above. If you send us your VIN we can also check it against the M270 application before you order.
Does the W176 M270 manifold air intake hose need coding or wheel alignment after installation?
No. The Mercedes-Benz W176 and W246 manifold air intake hose is a passive air-routing component, so it needs no coding or programming, and wheel alignment is not involved. Any stored fault codes from the leak can be cleared with a scan tool after the repair.
Who is a tested used Genuine manifold air intake hose for the W176 A-Class or W246 B-Class best suited to?
