Is there a recommended crank bearing solution to upgrade to? The only thing I saw in the thread was a mention of a photo in a Facebook group
There is a zero chance of a class action being of any value to most of the folks having this issue because they are modded. That kills it point blank. Further, this issue is v. rare in the scheme of things on stock cars.Can you imagine a class action though? None of us would qualify for it with all the stuff we have strapped to our cars.

I'm not interested at all in any sort of class action or legal action.
I'm interested in a technical discussion on this design because I'm truly confused by this failure mode - as an engineer and car guy with 30+ years of experience. If this forum/thread is not the place for a serious discussion, then I'll take it elsewhere.
I dont Understand it either. Why the main bearings fail on these motors is definitely a flaw in the design of the motor.
The question at hand is why does it come
Down to the bearing? Why doesn’t something else fail first to repair and prevent having to replace a motor.
Maybe if they were in the US because according to them, in order to complete this upgrade, they require you to send them your center main cap. Then they will complete the CNC modification and return the cap to you with a full set of 4 Thrust bearings. Bearings supplied are a replacement pair of OEM bearings to go in the block and a pair of motorsport ACL bearings for the cap.Yes, check out: https://prorace-engineering.co.uk/product/2-0tfsi-center-main-cap-thrust-washer-upgrade/
Looks like a good option.
What would be the minimum required work to install the thrust bearings? Remove trans and install new bearings with the engine mounted? Or will you need to pull the engine completely?Maybe if they were in the US because according to them, in order to complete this upgrade, they require you to send them your center main cap.

You can probably find a local machinist to do the same work and purchase the ACL bearings yourself.
Here's a video that talks about how to properly assemble the thrust bearings and main caps to avoid crankwalk...
Man that sucks, especially with the OEM DMF, no one is safe. I do find the clutch issues you had before it happened interesting and wonder how/if a failing thrust bearing would cause it to feel like a failing slave cylinder. Crankwalk always seems to sneak up without warning, which is why Im interested in this.So... Add me to the club. I upgraded to the Sachs basic performance clutch with VW OEM DMF and drove 55k miles on it. A couple of months ago I started to have clutch issues where the pedal would stick coming back up and thought "great, slave cylinder is failing". Then, last week I got a low oil pressure warning amongst other codes and immediately parked it.
Finally dropped the pan last night:

Anyhow, this really stinks and I think I'm done with VAG cars at this point. I've had many and almost all have ended in tears at about 100k miles.
- What I don't understand is the failure mode on this design.
- I inspected the bearing and it's hardly worn.
- How does it wear slightly and then just "fall" out of its cradle?
- The entire point of a bearing is be the sacrificial part to take the abuse gracefully and when end play gets out of tolerance, be replaced.
- What specifically is going to be damaged on the crank/block after this bearing fell out?
- Has anyone ever had a positive outcome dealing with VW on this issue?
