4 TPMS Tire Pressure Sensors for Mercedes Marco Polo W447 and V-Class W447 – 4 Pack (A4479050500 / A4479051704)
Product description
What it is
This is a 4‑pack of tyre pressure monitoring sensors designed as aftermarket replacements for several Mercedes models, including Marco Polo W447, Vario, V-Class W447 and Viano W639, with OEM references A4479050500 and A4479051704. The set is presented as plug‑and‑play, intended to replace old or faulty sensors without complex installation.
Who it’s for
It’s aimed at owners of affected Mercedes models seeking a straightforward, affordable replacement for worn TPMS sensors. If you’re comfortable with a non‑genuine part that claims direct replacement, this kit could simplify maintenance and keep tyre pressure monitoring active.
What stands out
On the page you’ll find explicit compatibility ranges by model and year, which helps avoid buying a sensor that won’t work with your vehicle. The supplier emphasises easy replacement and direct compatibility, which can save time compared with more opaque aftermarket options. It’s important to note the sensors are aftermarket, not original equipment, so you’ll want to verify fitment before ordering.
Limitations to note
The description notes the sensors are “not genuine” and invites careful fit verification. This means there is a potential mismatch risk if your exact build or year falls at the edge of the stated ranges. In practice, TPMS compatibility can hinge on vehicle software and wheel design, so it’s sensible to double‑check part numbers against your vehicle’s VIN or consult a professional if you’re unsure.
How it performs in everyday use
If you prioritise a cost‑effective, simple swap, these sensors offer a practical route to restore TPMS functionality after a failed unit. The offer of a 4‑pack is handy for a full wheel set replacement, reducing the need to source sensors separately. However, durability and long‑term accuracy can vary with aftermarket parts, so it’s wise to monitor readings after installation and consider rechecking periodically.
Pros and cons in practice
- Pros: clear OEM references, explicit model/year coverage, convenience of a full 4‑pack, described as plug‑and‑play.
- Cons: not genuine, potential fitment issues if your exact configuration is at the margins of the listed ranges, performance reliability compared with OEM sensors may differ.
How to decide if it’s right for you
If you own a Mercedes that matches the listed models and you want a cost‑effective replacement that you can install with minimal fuss, this kit is worth considering. If you require guaranteed OEM compatibility oryou rely on long‑term TPMS precision for critical driving conditions, you might prefer a genuine part or a verified alternative.
What to check before buying
- Confirm your vehicle model and year align with the compatibility notes (W447/Mercedes range, Vario, Viano W639, etc.).
- Verify the OEM references A4479050500 or A4479051704 match your part requirement.
- Decide if you’re comfortable with aftermarket sensors and plan to monitor TPMS readings after installation.
- Consider whether you have access to a tool or service to programme or initialise new TPMS sensors if required by your vehicle.
Practical example of use
Imagine you’ve noticed a slow leak or a frequent TPMS warning. Replacing all four sensors at once with this kit could restore consistent tyre pressures across all wheels, helping to maintain fuel efficiency and even tyre wear without multiple trips to a workshop.
In the context of alternatives
Compared with OEM sensors, this 4‑pack offers affordability and convenience but may require more follow‑up checks. If you prioritise absolute compatibility and long‑term reliability, an OEM option or a verified alternative may be preferable. If you’re simply trying to get back on the road quickly and at lower cost, this kit is a sensible middle ground.
