Hey all,
So i'm finally taking the leap and buying a 2013 Golf R (beautiful dark gray metallic 2dr, 6spd, sunroof, nav, leather, everything).  I probably won't venture into tuning this thing myself since it's so new (and only 17k miles), but i do want to know more about it in case i want to play around.  I have plenty of reading to do, but any initial guidance on MED9 would be awesome.  I've become fairly comfortable with ME7, but MED9 is all new to me.  I ordered an MPPS clone this morning.  Is this the best tool for read/write  with MED9?

Thanks in advance!!

MPPS clones can't read or write MED9.x ECUs on Golf R, Golf 6 GTI Edition 35 etc.
The safest and most probably cheapest solution is BDM on MED9.

Nice car, have fun!

Later MED9.1 ecus have a different security access.
Some genuine tools do them through OBD just fine.

Checksums will either be done by the tools or by WinOLS with the correct plugin.

Thanks for the info!
