Mercedes Citan W415 Engine Codes — The Complete Database
Every engine fitted to the W415 Citan — from the entry-level diesel to the 1.2-litre petrol and the later OM608 update.
Overview
Mercedes Citan W415 — Overview
The W415 is the first generation of the Mercedes-Benz Citan, introduced in October 2012 as the successor to the Vaneo.
Developed as part of the Daimler-Renault-Nissan Alliance, it is a badge-engineered variant of the second-generation Renault Kangoo, assembled alongside it in Maubeuge, France. Offered in panel van, Mixto (glazed van), and Traveliner (MPV) body styles across three lengths, it served as Mercedes' entry-level commercial vehicle. The range was powered predominantly by Renault's K9K 1.5-litre diesel in OM607 and OM608 forms, with a 1.2-litre petrol available in some markets.

Market Intelligence
The OM607/608 K9K diesel engine family remains one of the most-requested light commercial engines in our data, with enquiries concentrated on the 109 CDI as these high-mileage vans exit fleet service.
Best & Worst Engines
Best Diesel Overall
OM608.915 (post-2019 111 CDI, 116 bhp)
“The later K9K diesel offers the most power in the range — 116 bhp and 270 Nm of torque — with improved emissions compliance. Turbocharger and injector wear are its known weak points, but the K9K is one of Europe's most common diesel engines.”
Who it's for: fleet buyers who need the most capable Citan diesel.
Best Petrol Overall
M200.711 (112, 1.2L petrol)
“The 1.2-litre four-cylinder petrol offers simple, reliable motoring without the DPF and injector concerns of the diesels — ideal for urban delivery work where diesel emissions compliance is a headache.”
Who it's for: urban delivery drivers who want petrol simplicity.
Highest Risk
OM607.951 (pre-2019 108/109 CDI)
“The early K9K diesel is a high-mileage workhorse, but injector failure and turbocharger wear are common on vans over 100,000 miles — and EGR/DPF clogging is a persistent issue for urban delivery work.”
Who it's for: buyers who accept the risks of a high-mileage diesel and have service history to prove maintenance.
Most Expensive Failure
OM608.915 (post-2019 111 CDI)
“The most powerful K9K diesel offers the best performance, but the added complexity of the Euro 6 emissions system — including AdBlue — means more components to fail and higher repair costs.”
Who it's for: buyers who need maximum diesel power and accept the emissions complexity.
Best Value
OM607.951 (109 CDI, 90 bhp)
“The mid-range diesel offers genuine versatility with 90 bhp and good fuel economy — and sits in the same used price bracket as lower-powered examples. It's the sweet spot of the diesel range.”
Who it's for: buyers who want the most common, best-supported Citan diesel.
Most Overlooked
M200.711 (112, 1.2L petrol)
“Often ignored in favour of the diesels, the 1.2-litre petrol offers simple, reliable motoring without the DPF and injector concerns — and lower purchase prices because buyers overlook it.”
Who it's for: buyers who want petrol reliability without the diesel's complications.
Mercedes Citan W415 — Ownership Economics
The W415 rule
A £1,800–£3,500 OM607/608 recon against a £3,000–£8,000 W415 sits at 25–115% of the van's value — on sub-£4,000 examples, it approaches or exceeds our 70% Mercedes-Benz threshold. The petrol M200 recon at £1,500–£2,800 is the cheapest option. These are commercial vehicles; value the van's remaining useful life first, because the engine can easily be worth more than the van on budget examples.
Key Takeaways
Which W415 Costs Least To Own?
112 (M200 petrol) — cheapest recon, simplest maintenance.
Which W415 Costs Most To Own?
111 CDI (OM608) — Euro 6 diesel complexity and AdBlue costs.
Which W415 Is Best Value?
109 CDI (OM607, 90 bhp) — best-supported diesel without the Euro 6 complexity.
Common Problems
W415 Engine Replacement Costs — By Engine and Condition
No Generation variance from the baseline figures — the W415 shares its Renault Kangoo platform with the OM607/608 K9K diesel, and engine-bay access is consistent across the range.

Scope note: All variants listed are W415 Citan only (2012–2021). The second-generation W420 (2021–present) is covered on its own Generation Page. Note the engine power output changes between the pre-2019 OM607 and post-2019 OM608 diesel variants: 108 CDI went from 75 bhp to 80 bhp; 109 CDI from 90/95 bhp to 95 bhp; 111 CDI from 110 bhp to 116 bhp. The M200 1.2-litre petrol was not available in all markets.
