Years ago when I was a ASE Certified mechanic at car dealerships I seen several engines sludged this bad and worst. It comes from running the engine oil to long, even the correct oil will give up if run long enough. Most of them came in complaining the oil light flickered.
If they were running and not knocking to bad or not locked up we took the oil pan and valve cover off and cleaned them with a brush and parts washer solvent, spray can carb cleaner, kerosene,etc. ( doesn't matter at this point). Make sure you clean the oil pick up screen good.
Then we put it together with fresh oil and filter, run it 10 miles and changed the oil & filter again and they ran fine.
In the OP case I would do the above plus buy a used turbo at a salvage yard and run it.
I've seen turbos ruined from lack of oil changes but the engine was fine after a good turbo was installed and the lines cleaned. Good Luck and let us know how this turns out.

This was at about 95k miles when I had to change the oil pan on my 02 ALH Summer 2013.

Those pictures are interesting to say the least. It's almost like the oil turned to tar and left a coating of it only on some surfaces but not others.
I'm not sure how that's even possible. I would think the entire surface under the valve cover would be coated but it's not.
Interesting to say the least.

I know this is completely besides the point since you already had a engine failure. But, my shop teacher I had in high school was given a diesel rv, I good running fixeruppper. The only terrible thing about it was the engine was horrible inside, and looked almost a touch similar to this if not worse.

He drained the oil, added diesel to the crank case, and let it idle for 5minutes, did this 6times, all while the motor was warmed up. The diesel came out black as can be, the inside of the motor was really clean. He let it drain overnight and added oil. Sold it a month later. A year later, it came back to be serviced, the inside of the motor was spotless. So many of my friends have done this to there desert trucks with similar results. Its a bummer you had a failure due to PO neglect =(

Does that TDI have a gear driven oil pump or chain? If chain, I would check the chain tensioners for wear.

The previous owner needs to be biach slapped a good one. Do that to an engine... ...WTH is wrong with him? When my wife had a TDi (2005 Beetle) I changed religiously first using the dealer recommended Castrol TXT 505.01 5W40, then a couple intervals on the "new" Castrol 5W30 "Professional OE" 505.01 when dealer no longer carried the TXT, and then to Rotella T6 5W40 after warranty expired. Never felt quite right about the 5W30 505.01 stuff but the dealer said it's what VW went to. Sold the car in 2012 after scheduled timing belt replacement and some other 100K mile service items were completed and new owner was going to keep it on Rotella T6.

I just don't get how some folks can neglect their machines so callously.

I couldn't agree more... even my beater vehicles or those that don't get lots of use get love.... I just don't understand how people mistreat something they pay $$$$$$$$ for...........

I often find the opposite is true. They finance the most expensive car the bank or dealer will allow, and in order to pay back the debt, that same person will do anything to avoid maintaining that car.

It really annoys me.

That's some grody stuff there. Does the engine warm up properly?

Looks like a WVO or BioD car that got neglected...more than likely WVO.

I do a somewhat regular servicing of VW TDIs for folks. The keys to VW TDI maintenance are: use only a 505.01 synthetic diesel oil( 507 oils for 2009 & up) ALWAYS use a bottle of engine flush for 10 minutes before draining old oil at every oil change.
I would not run the engine for more than 30 seconds w/ the diesel fuel in the crankcase. But, if its effective, well have at it. One other reason for the sludge is that the EGR may be crudded up beyond the point of redemption. On the engine pictured, the EGR definitely needs replaced or deleted. Non-spec oils will shorten EGR life on a TDI. The service manuals state that if the EGR is plugged more than 1/3, replace the EGR valve instead of cleaning it. Pulling the intake and cleaning it would also be a good idea too.

This is just bad info.

ALH Use 505.00 or equivalent 5w40 synthetic diesel oil
BEW/BRM/BHW Use 505.01 approved oil only.
Anything past 2009 use 507.00 approved oil only.

There is absolutely no need for any engine flush unless trying to save a neglected engine and even at that you risk plugging the oil pickup.

Do not use engine flushes it is not a "key" to maintenance. It is stupid and wrong.

That engine had 1 of 2 possible lives. It was either run with WVO(Greasecar for one) and it is a know fact WVO will cause engine oil polymerization which requires more frequent changes. It was run with the wrong oil all together at at extended intervals as well. The car was abused.

EGR will not cause sludge like this, period. Diesel engines turn the oil black just from combustion gases alone. Non-spec fuel and over fueling will shorten EGR and engine oil life. This was caused by neglect and possibly WVO use.

The reason EGR & intake clogging was such an issue before was because of LSD. I'll admit ULSD didn't solve it completely but it made great strides it not causing the intake to be completely blocked.

EGR can be cleaned unless it is broken mechanically it just may be easier and less time consuming to replace. The same can be said for the intake.

Go to TDIClub.com and read before you kill an engine by using flushing agents.
