Car in question is an 02 VW TDI which only recomends full synthetic oil and I have heard too many horror stories to want to use dino. So, can I Rx with full synthetic for all phases?
Auto Rx with full synthetic

General story I have heard is that synthetic is fine for clean but you need Dino for rinse.
Have you considered:
AutoRX clean with whatever Synthetic you normally use.
AutoRX Rinse with a Group III "synthetic" like Castrol Syntec which presumably does not have the polar issues of a "true" syn like Mobil 1.
Lots of people get hostile with Castrol for calling it a synthetic. It may be a lot of money to pay for a group III oil, but it is a good oil and there is probably agrade appropriate for your car.
That being said I am currently running an AutoRX clean cycle in my Porsche 944 Turbo using Castrol 10w40 Dino and am going to rinse with Dino Esso XD3 15w40 HDEO, after which I will go back to full synthetic 0w40. I think the short cycles with AutoRx and a quality Dino will not hurt my engine.

I know I know VW wants you to run oil that meet that reg what is it 505.12 or some such crap ...but when you do it is okay to run the oil 10 thousand mile between changes ...and oil that meets that reg can easily go that 10,000 miles ..and if you are changing your oil in your TDI any sooner than that without having at least 1st eastablished a wear trendline by doing a few UOA you are wasting $$$$$.
Anyway that is my point is that 505.12 or whatever is for running a 10,000 mile change . Otherwise I belive you risk your camshaft a mear 1500 miles on say Delo 15w 40 will do no harm at all to your engine ...just don't tell the folk at VW or they may use it as an exuse one if you do indeed have a problem one day with your car stereo

Thanks.
Synthetic oil does not protect better than dino.
It's a fallacy that synth is better at everything.
If you are going to do an AutoRX treatment, follow the directions for the best scenario, which is dino clean (non competition with esters) and a dino rinse. NO HARM WILL BEFALL YOUR ENGINE!
This synth neurosis is plain crazy.
You'll be talking to the elves next.

*cough*
On a 10,000 mile drain interval , on a turbo motor you would have to be insane ( IMHO) to use a dino .. and yes I do believe that most dino are very good ...you are talking to the man that took dino oil 44,000 mile without cracking the drain plug!
what's the deal with the hostility, noobie? you may have a valid point, but berating others doesn't help anything. and why not provide some facts yourself to the apparently less enlightened.

how old is the engine? I see no reason to use it in a newer TDI. You might want to clean the sooty gunk form the intake passages, but thats not something that rx will rix anyway.
Put delvac 1 into it and run, run, run it.
My MB had a spotless, like new oil pan and under cover with 220k miles on it... HDEO and delvac 1 do a diesel good.

If you have the arx, then use it even though I see no need for it(unless you bought the TDI used without maintenance records).
I don't see why any of the cheap synthetics couldn't be used. Most are group III mineral oils.
I know that they don't want competing esters during the rinse phase, but whats wrong with the pepboys/wallyworld/advancedauto/autozone no-name group IIIs?
I guess that a good 15w40 HDEO should be no problem(even in a TDI) during a rinse phase which only lasts 2k-3k miles. Then go back to the synth!
