A Genuinely Distinctive Cause Worth Checking: Water Ingress Through the Washer Seal — Citroen Berlingo Spark Plugs
If you're chasing a persistent single-cylinder misfire that hasn't responded to a new coil pack or plugs, this is genuinely worth knowing about: a documented pattern on this platform links water leaking through the windscreen washer reservoir seal to shorting out the nearest fuel injector, causing exactly this kind of stubborn, single-cylinder misfire. A genuinely useful diagnostic clue worth checking directly: if you remove the spark plugs and one specific plug looks noticeably darker or wetter than the others, this points toward that specific cylinder's injector being affected by moisture rather than a generic ignition fault.
If you're testing a coil pack directly, one documented method involves lightly spraying water on the coil while the engine is running and watching for visible arcing, which would confirm a breakdown in the coil's insulation — worth approaching this test with appropriate caution given it involves water near live electrical components.
Citroen Berlingo Spark Plugs: A Cheap Part That Causes Expensive-Feeling Problems
The Citroen Berlingo's spark plugs rarely fail dramatically; they just quietly degrade, showing up as a rougher idle or slightly blunted acceleration that gets blamed on other things. The part costs next to nothing, which paradoxically makes it one of the most commonly neglected items under the bonnet.

Citroen Berlingo Spark Plugs: What They Do
On the Citroen Berlingo, the compressed fuel-air mixture in each cylinder is ignited by the spark plugs, and their condition feeds directly into combustion efficiency, fuel economy and how smoothly the engine runs. Only petrol engines use them; diesels rely on compression alone.
Citroen Berlingo Spark Plugs: Generations, Engines & Spark Plug Count
| Diesel variants (BlueHDi) | Not applicable — diesel engines use compression ignition and have no spark plugs at all |
|---|---|
| 1.2 PureTech/THP (standard petrol trims) | Genuinely only 3 spark plugs — this engine is shared across the wider PSA/Stellantis range (Peugeot, Citroen, DS), not a four-cylinder |
| GTI/GT (1.6 THP, where fitted) | 4 spark plugs — the performance derivative uses a genuinely different, larger four-cylinder engine from the standard car's 3-cylinder unit |
