Cylinder 5 misfire.
P0305 is a ignition fault code, typically costing £30–£800 to put right in a UK garage.
Most P0305 repairs land between £30–£800 including parts and labour. The spread is wide because the cheap fix (a sensor, a hose, a leak) and the expensive fix (a major component) throw the same code — which is why a proper diagnosis before parts are bought saves the most money.
Drive gently.
Urgency: high.
