Overview
Mercedes-Benz Sprinter W906 — Overview
The Mercedes-Benz Sprinter W906, also known as the NCV3 (New Concept Van 3), is the second-generation Sprinter, introduced in Europe in 2006 as the successor to the T1N (W901–W905).
Production ran until 2018, when it was superseded by the W907. The W906 was offered in a vast range of body styles — panel vans, chassis cabs, minibuses and crew cabs — with two weight classes (2500 and 3500) and multiple wheelbase and roof height options. The engine range was one of the most diverse of any Sprinter generation, spanning the OM646 2.1-litre four-cylinder diesel (2006–2009), the OM651 2.1-litre four-cylinder diesel (2009–2018), the OM642 3.0-litre V6 diesel (2006–2018), the M272 3.5-litre V6 petrol (2006–2010), and the M271 1.8-litre turbo petrol (2008–2013), the latter also available as a bi-fuel LPG variant (316 NGT).

Best & Worst Engines
Thin-Data Summary
“Thin-Data Fallback mode applied — compressed to a single paragraph. Best & Worst Engines: The W906's engine range splits into three distinct tiers. At the top sits the OM651 2.1-litre four-cylinder diesel — a modern, efficient and proven workhorse that powered the majority of UK Sprinters from 2009 onwards, offering strong fuel economy and excellent longevity. The OM646 2.1-litre diesel (2006–2009) is similarly durable, though older and less refined. The OM642 3.0-litre V6 diesel is a legend — smooth, powerful and effortless for heavy loads — but the oil cooler seals are a well-documented weakness requiring significant labour to rectify. The M272 3.5-litre V6 petrol is a rare choice in the UK — smooth and powerful but thirsty, and balance shaft wear on pre-2008 examples is a known issue. The M271 1.8-litre turbo petrol (including the LPG-fuelled NGT variant) offers lower running costs for urban use but is less common in the UK. For most buyers, the OM651 diesel represents the sweet spot — the UK's favourite Sprinter engine, with proven durability and manageable running costs. Who it's for: commercial operators and fleet buyers who need the sweet spot between economy, reliability and whole-life cost.”

Mercedes-Benz Sprinter W906 — Ownership Economics
The W906 rule
A £3,000–£5,000 OM651 recon against a £4,000–£12,000 W906 sits at 25–125% of the van's value. On a sub-£5,000 high-mileage example, that exceeds our 70% Mercedes-Benz threshold — walk away. Against a well-maintained £8,000+ example, the same recon drops to 38–62% — a repair decision, not a financial one. For OM642 V6 vans, the economics are similar — a £4,500 recon on a £10,000 example is 45% — viable. Value the van first, but remember that a well-maintained Sprinter holds its value better than most commercial vehicles.
