Mercedes Vito Underbody Protection Guide: What to Protect by Generation
Mercedes Vito skid plates are application-specific. The W639 and W447 listings differ by production range, engine, drivetrain and protected area. Start with the VIN and the vehicle’s exact configuration; a matching year alone does not establish fitment.
For W639, the listed choices include separate engine protection, a 4×2 gearbox plate, and a 4×4 gearbox and transfer-case plate. W447 listings include combined engine, gearbox and radiator protection, with front-bumper or EGR and Stop&Go coverage stated only on particular products. Read the protected areas on the individual product page before ordering.

W639: separate engine and drivetrain protection
Engine plate
The W639 engine skid plate is listed for 2003–2014. It protects the engine area, uses 2 mm steel and weighs 4 kg. Its catalogue information includes 2.2 D, 3.0 D, 4×2 and 4×4 configurations; confirm the exact combination by VIN and underbody layout.
4×2 gearbox plate
The separate W639 4×2 gearbox plate is listed for 2003–2014, with 2.2 D and 3.0 D in the product information. It protects the gearbox, uses 2 mm steel and weighs 16 kg. It is not a substitute for the engine plate.
4×4 gearbox and transfer-case plate
The W639 4×4 gearbox and transfer-case plate covers two drivetrain areas named in its listing. It uses 2.5 mm steel and weighs 17 kg. Its 4×4 application should not be inferred to fit a 4×2 van.
W447: compare the exact protected zones
4×2, 2.0 D or 2.2 D
The W447 4×2 combined plate is listed for 2014–2026 with 2.0 D, 2.2 D and rear-wheel-drive 4×2 information. Its stated zones are the engine, lower front-bumper area, gearbox and radiator. The product specifications list 2.5 mm steel and 28 kg. The word “bumper” describes the listed lower protection zone, not complete enclosure of the bumper.
4×2, 1.6 D
The W447 1.6 D 4×2 plate is a separate 2014–2026 application. It lists engine, gearbox and radiator protection, 2.5 mm steel and a weight of 10 kg. The listing does not name front-bumper coverage; do not transfer that claim from the 2.0 D / 2.2 D product.
4×4, 2014–2020
The W447 4×4 steel plate for 2014–2020 lists EGR, engine, gearbox, radiator and System Stop&Go areas. It uses 2.5 mm steel and weighs 28 kg.
4×4, 2020–2026
The later W447 4×4 steel plate for 2020–2026 lists EGR, engine, gearbox, radiator and System Stop&Go areas. It is a separate catalogue application, also listed as 2.5 mm steel and 28 kg. Check the vehicle details rather than assuming the two year ranges use identical mounting points.
4×4 aluminium, 2020–2026
The W447 aluminium plate lists engine, gearbox and radiator protection, 3 mm thickness and 11 kg weight. Its product information names 2.0, 2.2 D and 4×4; check the VIN and mounting layout before comparing its weight with a steel plate.
How to choose the correct plate
- Confirm W639 or W447 and the production date, not just the registration year.
- Check engine and drivetrain: 4×2 and 4×4 listings are distinct; the W447 1.6 D has its own application.
- Decide which area needs protection. An engine-only plate does not also cover the gearbox; the 1.6 D W447 listing does not state front-bumper coverage.
- Compare the product’s VIN fitment, body version, existing undertrays and mounting points before ordering.
- Check service access and clearance after installation. Reinspect the plate and fasteners after a hard impact.
The supplied kits include mounting hardware and instructions. Installation should follow the product-specific mounting sequence; if fitment or access is uncertain, use a workshop. For road-impact warning signs, see our pothole damage guide.
Mercedes Vito underbody protection FAQ
Does one plate fit every Vito of the same year?
No. Production ranges overlap, and engine, drivetrain and mounting layouts vary. Match the individual product listing and confirm fitment by VIN.
Does a W639 engine plate protect the gearbox?
No gearbox coverage is stated for the engine-only listing. The W639 catalogue includes separate gearbox applications for the stated 4×2 and 4×4 configurations.
Does the W447 1.6 D plate protect the front bumper?
Its listing names the engine, gearbox and radiator, not the front bumper. Choose by the stated product coverage and exact vehicle configuration.
