u I was reading the DIY
Servicing article on the VW Polo (CM, June 2017) and noticed that in Step 13 the spark plug gap is listed as 9mm, which I think should read 0.9mm. Is that correct? Mike Peters Martyn Knowles responds: Yes, sorry about that. We missed the 0. off the figure, so it should read 0.9mm. But if, like me, you buy those three- or four-prong spark plugs from NGK, Beru, etc, there is no need to adjust the spark plug gap.
