How is it that the 2004 to 2006 2.5 litre TDi MUST use 505.01 or 506.01 oil but the same engine in the 2006 to 2009 can use 507?
Yes, I know all that. BTW, I've never been able to find out what's different about the bearing material. Everything I've read says steel back babbit bearing, same as has been used since the early 60s.This has been been discussed ad infinitum over the years.
VW 506.01 has a special additive, Zinc DialkylDithioPhophate (known as ZDDP), to prevent the premature wear of the camshafts whose lobe angles in the R5 and V10 are so acute the pressure splits oil molecules.
ZDDP is a sacrificial anti-wear agent.
VW 507.00 doesn't work with the big end bearing metals in pre-DPF R5 and V10s.
Read the thread below.
There are many other threads on mytreg, clubtouareg and elsewhere confirming that VW 507.00 is NOT a replacement for VW 506.01 for those cars where VW 506.01 was originally specified.
And there are lots of threads confirming that a great many VW dealers haven't got a clue, give the wrong advice and have been known to fill 506.01 engines with the wrong oil!

I can't access that site.507 is for engines with DPFs, which the earlier R5 doesn't have.
All your questions can be answered here
It appears to be backwards compatible possiblyThanks for that. Being of American origin there's no reference to the 2.5 engine but there is to the V10 which is mechanically similar.
It says not to use 507 in a V10 and because the have the same cam set up that would mean the advice is the same for the 2.5.
It still doesn't explain why 507 is recommended for the later 2.5 when it's strictly verboten for the early 2.5.
Yes, the later engine has a DPF but that has nothing to do with the cam or bearings.
It's so frustrating when they spend millions doing the research then next year they say it's OK.My guess is that VW changed the material or heat treatment or coating treatment or the mechnical design of the cam or the PD followers to eliminate the need for the high ZDDP 606.0
Of coa1 oil when they introduced the DPF on these cars and changed to 507 oil with its low ash requirements to slow DPF fouling. Pity VW does not properly explain the change.
Ok, that makes sense. I didn't know the later R5 wasn't PD.From my limited research on this forum re 2.5 oils , the change from 'early' to 'late' is around the fuel injection systems . E
arly used Pumpe Duse which was driven from the cam lobes , resulting in a narrower lobe and therefore more wear . Later used common rail , which explains the ability to us e a lower[?] grade oil . This info was gathered from many posts around 2013 , so it has been around for a long time.
I have the correct information for my vehicle, thank you.Touaregs didn't get the CR motors.... those were for the crafters and such.
If you'd quit being so cheap and get the service manuals and documentation that applies to the exact vehicle you have, you wouldn't have to rely to garbage info you get from ebay or from others who mislead you.

Reading is very important... and clearly above you!who mentioned a CR engine?
Later used common rail
So, if they weren't PD as per your deduction (not sure how this could be since)I didn't know the later R5 wasn't PD.
.... what were they?I have the correct information for my vehicle, thank you.
The r5 is also a Rather small, niche market overallDoesn't stop me trying to find out.
Often a manufacturer of after market parts that is making an improved part that adresses a known weak point will include this improvement in their advertising.
The window regulators for an E39 BMW for instance.
I'm just saying that I've seen no such advertising for an R5 cam.
I will. Also I used to have a relationship with Ivan Tighe when I was racing, they're just over in the next suburb.Talk to Clive Cams in Ballarat
