Hey all,

Hoping to get a bit of help with my new to me Tiguan. Itís giving an error P0303.

Iíve changed all four spark plugs and switched around the coils, with P0303 still showing after idling for a short period.

When it drives, the CEL disappears once I get to about 20kmh. On idle it gets rough and thatís when the CEL comes back on then the EPC.

Iíve noticed some white smoke from the exhaust after the spark plug change and Iím not sure if thatís related or just because itís raining here.

Does anyone have any other suggestions or hints? Should I replace the fuel injector on cylinder 3?

The car is a 2016 132tsi 2.0 4motion with AD1 engine (ea88.

Any help is greatly appreciated
