Good day everyone

I am interisted to know what is the differences between the CYZA and CYZB engines.

I have a Polo marketed and sold as the 2017 VW Polo 1.4 GP TDI Trendline, with CYZB engine and 6C model variant (came out with the 089 BCM)

They both are 1.4 TDI engines with the same bore and stroke. Both have the same heads as far as I can tell. The one makes 55kw and the other 77kw.

They came in the VW Polo. the Trendline got the 55kw CYZB engine and the Comfortline and Highline got the 77kw CYZA engine as well as the CrossPolo also got the 77kw CYZA engine.

Im not too sure about the Polo Vivo ones

Is it merely that the turbo is different or is it all in the ECU software?

I'll be interested to know, and please also reference your info (we are not interested in hearsay) so we may build this thread for future info.
