Thy_Harrowing covered a lot of ground but I'll reiterate a few items.
- Intake valve cleaning. Manual labour on this one, not the spray through the intake BS that doesn't work. Change the air filter while you're at it, if it hasn't been done recently.
Air filters (engine and interior) were previously changed at 102k miles and replacing both once again are part of my 150k maintenance. The intake cleaning is something I have been preparing for although I am doing my best to avoid until required. I have been running
top tier detergent gasoline and performing the much loved Italian tune on a daily basis once the engine has been warmed up.
Purchased OEM VW Charcoal Lined Cabin Filter / Fresh Air Filter and OEM VW engine Air Filter for $40 from ECS Tuning. Installed at 102k miles.

- When you had the cam changed did they change the chain and tensioner? If not the stock one is likely finished and should be changed.
Yes, both the timing chain and tensioner were changed at that time. Based upon the reading I did here I figured as long as we were in there those might as well be taken care of also.
Here is a partial list of the parts I had replaced when taking care of the intake cam and HPFP - I was out of town while the work was being performed so no pictures to share:

- Replace / regap your spark plugs. This is one of the most over looked simple things that almost everyone forgets about. The car is smoother / quieter and gets better HP and economy. I use a feeler gauge and gap it so that 0.7mm fits but 0.75mm doesn't and if you have iridium plugs then it should last you a long time because the gap only widens over time. So gapping just a hair on the tight side is the best low maint approach. Don't trust that plugs are pre-gapped properly. That's rarely the case!
Plugs and coils were replaced just prior to 100k since #3 was misfiring. I guess it would be a good idea to pull the plugs and check them since it has been 50k - thanks for the tip!
Coils and plugs were purchase from ECS Tuning for $199

- If you want to check for engine health you can do a compression test. Forgive me if I'm wrong but I think you should be between 190-200psi. If you have a cylinder that is lagging then be suspect of that engines longevity.
Good suggestion - maybe a compression test along with cylinder leak down would be in order for a more accurate view. If anyone can cite the actual pressure required please provide them. I do know that as a rough rule of thumb they should all be within 10% of each other.
- If you live in a climate that gets below freezing in the winter then I would change the PCV to the latest rev. They are notorious for sticking when it's cold. Signs are rough idle and sometimes white smoke out the tailpipe while driving.
I think I recall taking a look at mine and I believe it was the latest revision and was apparently installed previously although I need to check on that - thanks for the great tip!
- N80 Valve replacement is also a sore spot over time. It's easy and cheap to change.
Done
Purge valve N80 changed at 135k. Purchased at ECS Tuning for $13 plus clamps $2
Old valve - must have been changed previously - note screw clamps
New and old valves appear to be physically identical

- I'm not sure sure rev of diverter valve you have but if you don't have ... I think it's rev D then you might want to look at it for signs of rips ... or just replace it. They aren't expensive and older revs are prone to failure.
Oh, great catch - I definitely need to take care of this and probably should have done so previously. Car runs good and strong although this is a quick and easy maintenance issue - thanks!
- DSG fluid change. If you haven't done it then DO IT and it will be the last time you'll need to if 50K is your goal.
Performed the transmission service at 100k and am planning to repeat at 150k.
Transmission service kit purchased from Blauparts for $135
New filter installed
Contamination on first magnet
Contamination on second magnet
Transmission pan and magnets cleaned
Six liters of Ravenol T-IV fluid used
Adapter and hose from Blauparts used to gravity feed replacement fluid
Note: Engine was cooled for over an hour and was still quite warm while fluid was being replaced. Transmission pan read approximately 30 degrees Celsius when full. Engine was started and transmission was shifted into all gears for 5-10 seconds each while fluid warmed. Transmission pan temperature was checked again and read 45 degrees Celsius, excess fluid was drained and drain plug was reinstalled with engine still running. It appears approximately two liters of fluid were excess. Mileage is 98580 and it does not appear transmission was ever serviced previously.

- Bring the car up to >90deg and check that both your rad fans come on. Engines don't last that can't stay within operating temp and these fans are prone to failure. The brush blocks tend to stick and jam.
Fans were replaced around two years ago and seem to be doing fine although I will check them on the next warm day.
VDO cooling fan assembly was purchased from O'Reilly Auto Parts for $340 plus tax
Somewhat confused as to actual manufacturer since VDO was purchased by Siemens which became Siemens VDO, then Siemens VDO was purchased by Continental AG - all German companies and tier one suppliers to industry
Additional confusion regarding actual manufacturer since box declares unit was "assembled in Thailand." This is understandable to some degree since Continental and Siemens are international companies based out of Germany who both own dozens of manufacturing facilities worldwide. Definitely not made in Germany though. Note: Ozark Automotive is owned by O'Reilly Auto Parts as disclosed in their
2014 Annual Report

If the body and the interior are in good condition then I don't see why you would need to get rid of it. Put a few days of TLC and couple hundred in parts into this one and you should get your 50K more out of it.
Wonderful - that is what I had been hoping to hear. My goal is 200k and if I can reach that I will be ecstatic!
