Forester 2017 diesel CVT - transmisson number and fluid

[Mr B quick]

Hello

When I get my Forester I plan to flush the CVT fluid - I have an OBD tool that can measure the CVT fluid temperature live.  I'm aware that Subaru have mixed ideas on fluid changes but I am sure it is worth doing.  The vehicle has only done 33,000 miles but it is over 6 years old -  it never had a tow bar fitted but I have asked the dealer to fit an OEM tow-hitch with 13 pin electrics..  

So it might have only been lightly used.  I am going to play on the safe side with the CVT and the DPF  - two potential issue areas for the Subaru.

My question is what is the CVT model number for the 2.0D and what is the fluid reference number?  I have heard dealers aren't keen on selling fluid but I do want the OEM Subaru fluid.  I plan to do several flushes..

Thanks in advance for any useful info.

Regards

Mark
