I had to trade our 2018 Q5 for a 2019 Q5 in 2021 due to an issue which couldn't be fixed. Does anyone know the difference between the 2 engines in each model year as the 2018 calls for 5W-40 502 00 and the 2019 calls for 0W20 508 00. Just curious at this point although I just realized I have been putting the old spec in it for the last 30k miles and 5 oil changes. I never looked to see if it was a different spec as the 2 cars looked identical. Don't think I did any damage and probably would have put the 5W-40 in it anyway
 
It appears that National Highway Traffic Safety Administration (NHTSA) had proposed to increase the Civil penalty from $5.50 to $14 for vehicles produced that failed to meet the CAFE fuel efficiency mileage standards for MY 2019. I suspect that Audi and other manufacturers scrambled to find any way possible way to increase their corporate average, even by 0.01 mpg.

Although the administration ultimately rejected the proposal in 2019, the manufacturers had already implemented their strategic plan the prior year to mitigate their liability with compliance credits in anticipation of the regulatory change.

See the cars in my signature. One (2017) uses the 5W-40, the other (2019) the 5W-20. I see no difference in consumption and have had no problem with either. If you still have a warranty with Audi (possible because of the VW diesel fiasco) you may want to stay with the 0W-20 until the warranty is expired.
 
Yes
No internal engine changes. Keep doing what you have been using 502, or strike the happy middle ground with 504.
I will keep using the 502 00 5W-40 since I have been for quite a while now and I have 2 other cars that use this spec. It makes life simpler. I was curious if there were any actual changes.

2019 is the first year that the EA888 in the GLI/GTI specified 508 and the only change was a variable displacement oil pump to accommodate the lighter viscosity...not sure if the same occurred on yours.

Veryy most probably a different gearing for the oil pump. This is the case with
my own GTI (built 7.2024 MY2018) which it's the very first GTI engine specced
for VW 508 00 (0W-20) and I'd bet it's the same with your Q5.
I use to run VW 504 00 (5W-30) from the beginning (less than 500 mls) and
what I'd recommend to most with this engine.
There are more tweaks to the engine, at least to mine, not sure if it applies to
your specific engine but what's for certain is the taller gearing to the oil pump.


No internal engine changes.

Sadly wrong. Oil pumps are internal.

EVERY EA888 3G comes with a variable displacement oil pump from the
beginning (since 2012).

Would the gearing of the oil pump cause be to pump more oil? Curious how the higher weight oil (5W-40) would affect the engine. I have used it for almost 30 k miles with no I'll effects as far as I can tell
 
Something is different as a DAYB base engine has a part number 06L100033C and a DJYA has a part number of 06L100033F. However the crankshaft, conrods, pistons, camshafts, timing chain and cylinder head are the same part number for both engine codes.

Thanks! I think I will run what I have been 5W-40 502 00. Probably will trade it in a couple of years. The new 2024 GMC Acadia Denali looks nice and we need a bigger vehicle with the grandkids. Just don't want to buy a first or second year product and want to see it reliability

Yes, exactly. That change is intended to elevate the volume flow rate
to compensate for the (newish to VW/Audi at that time) thinner oil.

I hope so, just because you probably intend to 'affect' (improve) the
engine's life. Going one or two steps thicker will never do any harm.

Anyway I'd run either VW 504 00 or VW 511 00 instead before using
VW 502 00 but it's up to you. IMHO one step up (from 0W-20 to 5W
-30) is as stout oil as is meaningful.


I was referring to bearing clearances, galley design, etc...

Yes, the same AFAIK (if we're talking about EA888 3G above ~220 HP).
The less powered 1.8 TFSI and the Miller cycle 2.0 TFSI are a different
matter (smaller main and rod bearings, weaker crankshaft etc).


So it was just a gearing change in 2019 to keep pressures up with the 0W-20?

Yes, according to Audi publications (several SSPs). Not 100 percent
certain if there are some minor tweaks such as ECU SW changes etc.
as well.
