Blackstone Comments: The high wear and silicon are common finds in new engines. The excess wear is from new parts breaking while silicon comes from sealers used during assembly. Both should improve with subsequent oil changes. Universal averages for the 2.0L TDI are based on an oil run of 6,500 miles. This oil was run a lot longer, so that also contributed to the wear. Fuel at trace level isn't a problem and the TBN was strong at 3.2, so lots of active additive was left. 1.0 is too low. Stay with a 10,000 mile oil run for now. Once wear and silicon settle down, we'll suggest going longer.

Runaway aluminum.

There are other UOAs of factory fill common-rail TDI's on here and on TDIclub.com. Other than the aluminum, looks pretty normal for recent TDI FF. 174 is high aluminum even for factory fill though. I wouldn't panic yet though, see if it comes down in the next OCI.

Hi,
Bob - You are correct - as well, many people also think that Alusil construction may shed some aluminium and/or silicon.

IME with Porsche engines I have not seen this - not to say of course that it cannot/does not happen

Gents, Thanks for the feedback. I'll post the next UOA. I may have one done @15K. BTW, replaced FF w/Lubro Moly Top Tec 4200.

Is the FF on these the Castrol SLX or another oil?

Potassium at 469? Ours has been in the 50ppm range, and blackstone believes it is indicative of a coolant leak. Yet on yours, they have 0.0 in antifreeze column. They don't test for glycol, so it seems their antifreeze % is highly subjective. Granted our coolant does disappear very very slowly to some unknown place and this was mentioned on the oil slip.

For some reason VAG uses a factory fill oil that contains potassium. Don't know why but it's in all the used-oil test samples. So nothing to worry about there.

I would suggest not bothering with another used-oil test until 30k miles. All the wear metals should be much reduced and you might consider that test as a baseline for later testing at 60k miles and again at 100k miles.

Diagnosis FAIL. It is the FF. Now for the next change watch and see that Al hit universal averages because the FF was run as recommended by the designers and engineers of the engine.

Just to mention that the high levels of potassium are in the VIRGIN oil samples too.

2010 Volkswagen Golf 2.0L Turbo CR (TDI), CJAA engine code.
Replaced Factory Fill. 1st Oil Change @ recommended 10K miles.
Replaced 3rd Fill. (Lubro Moly TopTec 4200, used B2-B5 w/OptiLube). Dealer refilled with Castrol.
Note: I Changed the oil early since I was at the dealer and wanted a UOA on the LubroMoly. Wanted to see the fuel in oil results since I use biodiesel (B2 toB5). This car is driven in the CA desert. High temps and very low humidity, so assume that D2 evaporates from the crackcase a little easier than in other parts of the country.

@25,489; "This engine has made some nice improvements since the first time we saw it. Aluminum iron, copper and silicon have all improved enough that they're all in the average range. That's not to say they're "perfect" here, because aluminum could certainly stand to come down a little more (and so could iron), but it sounds like you're taking good care of this engine so improvements should come with time. A trace of fuel is no concern at all. The TBN read 2.9, so there's still active additive left. Try an oil run of 9,000 miles next time. Nice progress!"
