Mercedes Citan 111 CDI Injector & EGR Issues (W415, K9K)
If your Citan 111 CDI is a W415 generation model with the K9K Renault-sourced diesel — that's the 2012 to 2021 production run — injector failure and EGR clogging are well-documented patterns on this engine, backed by general Renault/Mercedes commercial vehicle consensus. We replace injector seals, the EGR valve and timing chain components as standard on every K9K rebuild.
The newer W420 generation Citan doesn't use the K9K engine and falls outside this specific issue — it's covered separately if you have a later van.

Every CITAN 111 CDI is different. That's why we offer the right solution for your engine, your car and your budget.
REBUILDING YOUR CITAN 111 CDI ENGINE
We rebuild the engine your CITAN 111 CDI already has instead of selling you a used engine of unknown history — strip it down, pressure-test it, and replace every worn or damaged component (timing chains, bearings, water pump, gaskets) with updated OEM parts. Near-new performance with a 12-month unlimited-mileage warranty.

ABOUT THE MERCEDES CITAN 111 CDI ENGINE

The Citan 111 CDI has been part of the Citan range since 2012, and across the W415 generation uses the K9K — a 1.5-litre four-cylinder diesel sourced from Renault and shared with the Kangoo of the same era. It's a reliable workhorse engine in its own right, but injector failure and EGR clogging are well-documented patterns on the K9K, especially in vans that have spent a lot of time on short urban runs. The Citan 111 CDI was discontinued from the range, but we continue to rebuild and replace engines for every one still on the road.
We continue to rebuild and replace M256 engines for every CITAN 111 CDI on the road.
MERCEDES CITAN 111 CDI ENGINE CODES

K9K (W415)
A 1.5-litre four-cylinder diesel fitted to the Citan 111 CDI from 2012 to 2021 across the W415 generation. Known for injector failure and EGR clogging over time — see the callout above. We replace injector seals, the EGR valve and timing chain components as standard on every K9K rebuild.
Check Your K9K Citan 111 CDIMERCEDES CITAN 111 CDI ENGINE COMPATIBILITY

Because the Citan 111 CDI uses a Renault-sourced K9K engine across the W415 generation, parts compatibility and engine matching are straightforward when confirmed correctly. We always confirm your exact engine code via registration or VIN, generation (W415), and any ancillary or ECU considerations specific to your build. This is why we always start with your registration rather than a generic Citan quote — it protects you from paying for parts that don't fit your actual van.
