Audi Q2 Spark Plugs: A Cheap Part That Causes Expensive-Feeling Problems
On the Audi Q2, spark plug wear tends to creep in quietly — idle gets a little rougher, throttle response softens slightly — the kind of symptoms that get blamed on almost anything else under the bonnet. Given how cheap the part itself is, it's an easy one to put off for longer than makes sense.
Audi Q2 Spark Plugs: What They Do
Inside each cylinder of the Audi Q2, spark plugs ignite the compressed fuel-air mixture, and their condition has a direct effect on combustion efficiency, fuel economy and how smoothly the engine runs. Petrol engines can't function without them; diesels don't use spark plugs, relying on compression alone to ignite fuel.

A Genuinely Useful Piece of Context Worth Knowing About Persistent Misfires — Audi Q2 Spark Plugs
If a coil pack replacement hasn't resolved a persistent misfire, this is genuinely worth knowing: documented cases on related Audi models describe a coil pack replaced for a specific cylinder's misfire, only for worn or carbon-fouled spark plugs to turn out to be the actual cause instead.
It's also genuinely worth knowing that failing to fully click the rear coil pack connectors back into place is a frequently documented cause of a misfire appearing immediately after fitting new coils, and that mixing coils from different sources rather than replacing them all together has been documented causing ongoing misfires.
