I agree that it's a shame that Volkswagen makes it that hard to determine what oil to use.
From a technical standpoint using a VW 504 00/507 00 (0W/5W-30) in a VW 508 00/509 00
(0W-20) application doesn't harm. Using a VW 508 00/509 00 0W-20 in an engine designed
for VW 504 00/507 00 0W-30 or 5W-30 may cause increased wear or even component failure.
So it's mandatory to determine the correct approval. When the manual says to ask the dealer
just .... wait .... go and ask your bloody dealer. Insist getting some print-out that says what oil
is recommended by Volkswagen for your specific car (VIN specific).
I also tried to find that new 147 kW/200 hk version of the 2.0 TDI without much success. There
may exist some better chance doing a google search when you kindly supply the engine code,
which you'll find on a sticker below the trunk and on page 1 or 2 of your manual.
Both the former 176 kW/240 hk Biturbo-TDI (engine code CUAA) and the 140 kW/190 hk TDI
(engine code DDMA or DFHA) are specified for VW 507 00 (0W-30/5W-30). Using the same in
your 147 kW/200 hk 2.0 TDI is IMHO a safe bet, but again, ask your dealer. However if you just
have to top-up 0.5 or 1 Liter, I'd use any VW 507 00 with confidence.
If/when you're certain VW 507 00 is the correct approval for your Tiguan and since you're based
in Sweden I'd recommend either M1 ESP or Ravenol VMP, both 5W-30 and VW 507 00. IF you'd
prefer using a 0W-30 (which is just marginally thinner at -20°C) I'd go for either M1 ESP 0W-30 or
Ravenol VSW 0W-30. Shell Helix Ultra Professional AV-L 0W-30 is a fairly worthwhile low-budget
alternative. I admit it's a matter of taste to some degree, but the mentioned 5W-30s are generally
more stout. Keep us posted!
