The only viscosity I've ever seen in 507.00 is 5w-30 but maybe it's different where you live.
 
VW spec is more important than viscosity.
 
Yes, you can mix engine oils.
 
Yes you can top up with castrol or Mobil  or whatever you please - as long as it meets the VW spec for your engine.  You can even mix 506.01 with 507.00.
 
Don't overthink it.

TSI doesn't suffer from cam wear issues

45k is a "minor service" same as 15k -  Basically oil & filter, check other fluids, visual check of major systems.  Should be around $300 - $350
 
I'm slightly confused - you've done 45k in 8 months?

Easiest way to tell the difference.
 
TFSI has a cartridge type oil filter that is located at the front of the engine, approximately in the middle pointing downwards.
 
TSI has a spin-on oil filter located at the front left of the engine, pointing downwards.
 
My theory is that if you can't identify the oil filter then you probably should stop at that point & leave it to somebody else.

yes, should start cooling near enough straight away

I believe the OP is talking about the caliper manufacturer, not the brand of pad available for purchase.
 
To the OP:  What PR # are your rear brakes?
 
1KF is Lucas/TRW.  They are smooth on top & taper in at the back.  The slot on the top is about 20-25mm wide & parallel the full length
1KD is Lucas/TRW but it has 4 fins on top & is square
 
The Bosch is smaller than the Lucas stuff (like a MK6 Golf).  The slot on the top is two opposing curves, almost like a circle.
 
This might help

that sounds far too sensible Laureen  :p
 
Have a look at your PR codes inside the service record book or on the build sticker in the boot

that was all at partsbase.org.  You should have had a look.  There are diagrams that are easy to follow

I think the handbook says look behind the filler flap.  It's the standard spot for VW group vehicles.
