Title: Filter Minder
Post by: Tom77 on November 22, 2015, 10:32:20 am
I would like to install a Filter Minder on a 92 Jetta Ecodiesel, and  also to know the best location to put it on the air filter box, and what kind for the size of the engine.

Thanks

Filter Minder?   Is that one of those do hickeys that measure the vacuum behind the filter and displays it as good or time to clean/replace? 

I would think that you would need to drill and tap a hole in the intake in order to make it work.  What purpose is it for?  The filter is an easy access item just pop it open and look through the filter with the sun behind it.  That has always been my test.  If it is dirty you will know. 

If you just want to install devices on the engine look into a turbo, or do you already have one?  if so add an Exhaust Temp Gauge.

Typically you'd install a filter minder in the top of the airbox. No idea what VW's spec is for maximum allowed filter restriction.

You actually aren't supposed to open the airbox to inspect the filter. The filter seal is only rated for a single use. Not saying I necessarily agree with that but that's what the filter manufacturers say. On heavy equipment you use a filter minder and replace the filter when it starts showing too much restriction.

The GM ones pop into a hole drilled in any plastic or metal  downstream of the filter  but upstream of the turbo via a rubber grommit.
There is no relation to engine size.
Depending what kind of dirt you have, visual inspection isn't always  that accurate, especially if  some  moisture has bonded a layer of fines into the filter, it can look  near new, and pull the filter minder to  the stop....good for  +10 MPH top speed in an RV I recently serviced.

My Dodge has one, and I change filters  around the midpoint, if I wait till it  gets to the red, she's  noticeably slower

Just curious............

Can the filter be cleaned once declared out of spec by the filter-minder??

Has anyone tried that and noted the "resurrection" of the filter after declared dead by the minder device??

Considering a MAN filter is about $5 for these engines, nope.

Air filters can be cleaned. Back in my days of running a Cat 518 skidder we used to blow out the outer filters with compressed air about once a week in the summer. I don't think the air filter manufacturer recommended that, but it never seemed to cause any problems. I also worked for an outfit that sent the outer filters in and had them cleaned. I was told that some sort of liquid solution was used in the process, but I've never actually seen it action. Of course logging is a much dirtier environment than any V-dub will probably ever see, so measures such as these are not needed on a car, but yes it can be done. As vanbcguy says.... cheaper to just throw in a new one.

Rabbit79,  had to laugh at this one.  Your skidder or cat will see more dirt on its filter in a day in the summer than any 10 VW's will see in their lifetimes.

Not exactly the same sort of driving conditions. 

Thinking of towing a Christmas tree behind mine for the summer.  Dedicated to logging the PNW.

I guess you could always rig up some chokers off the towing eyes on the back..... or if you were really industrious, build a grapple for it. Stump clearance on a Rabbit might give you some trouble though.  ;D

In school we were taught to never clean a filter with compressed air. The dirt blows out of the dirty side and air currents cause the dirt to become embedded on the clean side. Once you reinstall the filter, all the dirt on the clean side gets sucked into the engine.
