Cheap Mercedes-Benz Citan Glow Plugs

Yes, glow plugs exist on the Citan because it has always been offered primarily with diesel engines, which require glow plugs for cold starting. The Citan has never been sold in the UK with a petrol engine in any meaningful volume, so glow plugs are a genuine and relevant part for virtually all UK Citans. If you have an unusual petrol or electric variant, glow plugs would not apply, but for the vast majority of UK buyers this is the right part to be searching for.

The Citan has two distinct generations: the first-generation W415, produced from 2012 to 2021, which was based on the Renault Kangoo platform and shared many of its engines; and the second-generation W420, launched from 2022 onwards on a new platform with updated engine options. Generation matters significantly for glow plugs because the engine families differ between W415 and W420, meaning parts do not carry across the two generations. Always identify your generation first, then confirm the exact engine code for a reliable match.

Both a 2016 and a 2019 Citan fall within the first-generation W415 (2012–2021), so they share the same platform and engine family range, which is a promising starting point. However, fitment ultimately depends on whether both vehicles carry the same engine code – the 109 CDI, 111 CDI, and 112 CDI variants used different engine specifications across W415 production years. Check the engine code on your V5 or via a VIN check and supply it to the breaker so they can confirm the plugs match rather than relying on year alone.

No – the W415 and W420 are fundamentally different vehicles with different engine families, so glow plugs from the older generation are very unlikely to suit a W420. The W420 uses updated diesel units that are not carried over from the Renault-derived engines of the W415. Confirm with the breaker against your exact registration and engine code before purchasing anything across this generation boundary.

Trim level and body style have no effect on glow plug fitment – whether your Citan is a base panel van, a Mixto, or a Tourer passenger model, the glow plugs are determined entirely by the engine fitted, not by the trim or body variant. A Tourer and a panel van with the same engine code will use identical glow plugs. Focus on the engine code above everything else, and ignore trim or body designation when sourcing this part.

The single most useful piece of information you can give a breaker is your engine code, which you'll find on your V5 logbook or by running a VIN check – it will be something like OM607 or similar depending on your variant and generation. Alongside the engine code, tell the breaker your vehicle's year of manufacture and whether it is a W415 (2012–2021) or W420 (2022–present). Glow plugs are engine-specific, so getting the code right is far more important than quoting the year or trim, and a good breaker will be able to confirm compatibility against your registration.
