No worries about using the 503.01 oil in your car as BOTH of them are certified 502.00 as well. I have a copy of the VW/Audi Technical Bulletin dated 26-Jul-2005 regarding which oils are 502.00 certified, including (among many others) Mobil 1 0W-40.
 
If you want me to E-Mail you the bulletin, just look up my E-Mail address and I'll fire it right off.

Miramar Audi in San Diego, CA, uses 5W-30 Castrol Syntec because they say Audi recommends it for mild/warm/hot climates, like sunny parts of CA.
 
They claim the 0W-40 and 5W-40 is for colder climates?

"They claim the 0W-40 and 5W-40 is for colder climates?"
 
They do huh? If a dealership told me that about my new Audi I'd quickly be finding a new dealership as I'd never trust them to lay a finger on my car.
 
The fact is that 0W-40 will "out-winter" a 5W-30 AND "out-summer" that same 5W-30 regardless of the time of the year and the prevailing weather. Said another way, for your car that requires at least an oil that is certified to meet the VW 502.00 oil spec, there is no better oil for it than a 503.01 certified 0W-40 (a close second would be a 503.01 certified 0W-30).

Found the 502.00 certified oil I wanted by geewillie

I was mainly concerned with finding the proper VW/Audi certified 502.00 oil and didn't want to go to the dealers to buy it. I ended buying a quart, just as a spare for the car, from my mechanic I used for my out-of-warranty Passat -- for five bucks a quart, which I considered a deal. I can't recall the viscosity, but it met my needs that the manufacturer insists upon.

It isn't all that difficult to find 502.00 oil. Virtually every K-Mart, Walmart, NAPA and Autozone that I've been in recently has at least one of the following on the shelf:
 
Castrol Syntec 5W-40
Castrol Syntec 0W-30
Mobil 1 0W-40
 
The first is only certified as a 502.00, the last two are certified as both 502.00 AND 503.01 (which means they are MUCH better oils).

Care to enlighten us on how 503.01 is a much better oil? What makes it better? What characteristics and properties does it exhibit, what performance gains are achieved?

Scroll up to message number 2 of this topic and follow the link I posted to the VW Oil topic. In there is the list of applications that the various oil specs were developed for. Said another way, the engines with the highest specific output per liter, the highest pressure turbochargers, and/or the most mechanically complex are the only ones that require 503.01. What using the more robust oil translates to for someone who is driving a car that requires 502.00 is an extra measure of measure of shear resistance, an extra measure of heat resistance and greater level of protection against sludge formation (not an insignificant issue for VW & Audi owners).
 
Can I give you the specific benchmarks that VW requires for an oil to meet that lofty spec? Nope. I've looked and looked, and as of yet have been unable to find it. What I do know though is that oils based on Group III Hydrocracked Crude can be made robust enough to meet the 502.00 standard, however, not a single Group III oil has ever been stable enough to meet the 503.01 spec, that seems to be a realm where only fully synthetic Group IV oils need apply.

briskoda.net (add usual http://.www header to make complete) has a forum that discusses a number of oils for high performance VW and Audi vehicles.
The latest seems to be 503.01, which is specified for the Audi RS4, S3, and TTs' over 180 hp.

Oil Change by woffy

I had my 25,000 mile service last week at my Audi dealer. A couple of days later I checked my oil level. It was at the midpoint of the dipstick. There was no leakage and I had driven less than 50 miles. I called the dealer, described the problem and they said that they filled the reservoir to the midpoint on the dipstick due to expansion when the oil was hot. I'm hoping Shippo is reading this because I really respect his thoughts on oil related questions. Is this correct? I've always "read" this as 1/2 quart low over my 62 years.

That's a load of bull. Yes, it will expand when heated, but, um, 1/2 a quart. No. Tell them, nice try, but you'd like the other 1/2 quart, thank you very much.
