2 Radiator part numbers, which one?

[phem0r]

Morning all,

I have a leaking radiator and looking into pricing to replace myself. Looking on parts.vw.com for my VIN, there are 2 part numbers..

5K0121251AA - https://parts.vw.com/p/Volkswagen_2013_GTI/Radiator/60511866/5K0121251AA.html
1K0198251 - https://parts.vw.com/p/Volkswagen_2013_GTI/Radiator/48603637/1K0198251.html

The latter is $250 more, unsure why other than ULEV vs SULEV. Any other way to tell which one I require?

Thanks!

Check your engine code. CBFA motors require the more expensive option due to the sensor

Yep CBFA here. What does that sensor do exactly?

G611 sensor is a emissions related pain in the ass sensor. Some splice in a Mercedes Benz sensor . Shopdap has cbfa radiator with sensor for a bit cheaper $400
For this reason only I wish I had a CCTA Engine.
