I agree. If the existing/stock filter is less efficient, doesn't that presume that there are already contaminants (dirt, etc) that are less than 5 microns in size that are passing through the entire system?I'm thinking 5 microns is still better than no filtration. Hope your quest for a biner filter is successful and we see this great concept available to us again!
This is exactly the reason why I have no intention of removing my return filter. It will stay in my car - at least until 2micron comes up with a better design.I'm thinking 5 microns is still better than no filtration.

The ALHs and PDs run a CAT (2 micron) or a 1 micron filter as an upgrade to the OEM filter with no issues. Why would running one of these "type" be an issue with the CR?
As has been said, even at 5 micron, this is an improvement.
I'm waiting for that too. However, I'm lucky, so this is a low priority. Where I live moisture (in any form) is pretty rare. There is not much condensation when the relative humidity is measured in single digits. People here consider 30% humidity to be "muggy". They have no idea what muggy really feels like (I lived for several years in Louisiana). Also there is no issue with freezing when the temperature in my garage rarely goes below 50 degrees F. at night and daytime temps are always above freezing.I'm waiting on the IC drain kit. Seems like this would be the easiest to install and the least noticable when I get service done.
Mine will stay on my car. I still am using the original bracket. I do wish I got one of the new brackets simply for the elegant look of this solution! But, the original bracket certainly serves my needs.This is exactly the reason why I have no intention of removing my return filter.

If the filter works as planned (which is what the current controversy is about) it would drastically reduce the cost. Currently it is in the 7-10 thousand dollar range - replacing the entire fuel system from tank to injectors. With the return filter alone, you would only have to replace the HPFP, fuel rail and injectors. With the filter and 2microns HPFP mod, you would only have to replace the HPFP and one fuel filter (under $1000 in parts). This, of course, assumes that the filter actually catches all of the HPFP debris particles. Since there has not yet been an HPFP failure with these parts installed - this is all conjecture, not fact.On the return fuel filter I would be curious what the potential cost savings is for having this device in the event of an HPFP failure. I still don't have a handle on what the 'real' not dealership repair cost is for that failure, but I'd be curious if this would reduce the repair by $500 or several thousand.
I agree with your logic but it seems that the system needs a better filter than comes standard. I.e., the engineers were wrong. Otherwise we would not need to replace parts upstream from the filter. I have a vague memory from years ago that Bosch specified the filtration needed for the HPFP but I can't find it now. If the filter meets those specs then it is the Bosch engineers that were wrong. Does anyone have those specs?Also, I suppose one proof that sub 5 micron particles are less of a concern to the VW engineers is the fact that the main OEM fuel filter has a micron rating that is above 5 micron from what I recall. Seems like they didn't have worries about the need to filter down to less than 5 microns. I wonder what kind of sub 5 micron particulate crap is in our diesel fuel to begin with?
I do not know if 2micron is closely following these threads. It appears that there are many members here who are aware of the possible limitations of this kit and want it anyway. I would suggest sending PMs to 2micron. I do know that he has about 30 of these kits built, but he has officially suspended sales due to concerns about it's usefulness. If enough people tell him that they are aware of the issues and still want to buy it, he might be willing to sell some more. I cannot speak for him, but it can't hurt to ask.Can we still buy them if we want? I will rather have some protection over no protection. Keep up the great work.
