Cheap Mercedes-Benz Citan Crankshaft

The Citan exists in two generations: the first-generation W415 (2012–2021), based on the Renault Kangoo, and the second-generation W420 (2021–present), which uses a completely different platform. These generations share no mechanical commonality, so a crankshaft from a W415 will not fit a W420. Even within each generation, fitment depends entirely on the engine code, so always match on that rather than year alone.

The crankshaft is machined specifically to each engine's stroke and bearing dimensions, so the engine code is the single most important detail you need — more so than year or trim. On the first-generation Citan (W415) common engine codes include the OM607 diesel and the M270 petrol family; on the second-generation (W420) the OM608 diesel is widely used. Your engine code appears on your V5C or can be retrieved via a VIN check, and you should supply it directly to the breaker when requesting a quote.

No — trim level has no bearing on crankshaft fitment whatsoever. Whether your Citan is in base panel-van spec or a higher passenger-carrying variant, the crankshaft is determined entirely by the engine code and fuel type. You can safely disregard trim when searching, but do confirm the engine code with the breaker against your registration to be certain.

No, diesel and petrol crankshafts are not interchangeable — each engine family has different bore spacing, stroke dimensions, and journal sizes. The first-generation W415 Citan was sold with both diesel (OM607) and petrol (M270-family) engines, and the crankshafts from these are entirely different parts. Always confirm your fuel type and engine code with the breaker before purchasing.

Both a 2014 and a 2019 Citan fall within the first-generation W415 (2012–2021), so they share the same platform, but fitment still comes down to whether the engine codes match exactly. Mercedes-Benz did make running production changes within this generation, and ancillary or specification differences may affect compatibility in ways that aren't always publicly documented. Match the engine code first, then confirm directly with the breaker against both registrations before committing to a purchase.

A crankshaft replacement is a major engine strip-down job regardless of the vehicle, and on the Citan it is no different — the engine typically needs to be significantly disassembled, and bearing clearances must be checked and set correctly. This is not a DIY job for most people and should be carried out by a qualified mechanic or engine reconditioner. Whether any associated components such as bearings or seals need replacing at the same time is worth discussing with whoever is doing the work.
