Scirocco Central

Hi all.. just checking my servicebook for my 65 plate 2.0 TDI 150 R-Line and there was a recall on 05/12/17 Recall 23W6?

Anybody know What was this?

Cheers

If my my memory serves me right, it was to do with replacing one of the lambda probes. As far as I'm aware it was just the existing part was replaced with an updated part.
