Don't want to confuse everybody.

The part I took out from my 2007 car is 050 (see my previous post), for which, according to the Bosch site, has a Type Formula of PG-3-8. It is discontinued since 04/2014 and replaced by 114.

The always recommended P/N is 037, which has a Type Formula of PG-3-5, which seems less technologically advanced than 114 PG-3-8, according to the slide I found (see my previous posts).

050 should probably be fine.

The difference between PG-3-5 and PG-3-8 is that the PG-3-8 sensor implements the TPO (True Power On) feature, with a higher accuracy.

114 is working fine in my car, same plug.
