Subject: Re: [MBZ] OT: Golf heater fan
On the VW theme - we drove the Passat to Utica, NY and Boston over the
thanksgiving week (or two). The day before we were to leave Boston for home,
the check engine light came on. The car was still running fine, so I took it to
the local dealer for a diagnosis. Turns out that the "Ad-Blue heater" module
has failed. They recommended that I drive it home and deal with it here at my
leisure, which I did yesterday. Our local dealer confirmed the diagnosis, but
doesn't have the part in stock. He did quote $1000 +/- for the job, and of
course, the car is out of warranty. They are checking to see if the extended
warranty covers this part . . . It looks like most of the $1000 "customer
loyalty" bribe money from VW will go back to them to fix the car, if we get it
repaired. Since it's part of the emissions control system, and that system
doesn't do anything now, why bother to "repair" it?They did tell me that the
"fix" for the emissions system on the 2.0 Diesel is just a re-programming.

Since you guys (other than Loren) seem to have taken off from working on cars I
guess I'll relate the latest on the '05 VW Golf.
My wife rarely complains so it'd been a couple months before I realized that
the heater fan only comes on when using the highest position. A quick Google
shows that this is a pretty common problem that is probably failure of the
thermal switch on the resistor pack. A whole pack is available for less than
$20 or I could just replace the switch itself for $1 (gotta buy 5 though). I
opted to order new thermal switches and crimp in a new one.
The failed switch is probably just a symptom of the actual problem which is the
fan getting cruddy so I pulled the fan (not as easy as a 123 fan but easier
than a 201), hosed out the bearings with carb cleaner, then sprayed or dribbled
a variety of lubricating fluids back in to loosen things up. I had the best
success with Kano Kroil which also smells nice. Its not completely loose but
its much easier turning than it was. Since the fan isn't so hard to replace
I'll run it like this and replace if needed.
Amazon has a URO fan for cheap cheap but I refuse to go for it, I like the car
too much.
Sadly the new thermal switches won't be in until next week so I can't call this
a win. I'll let you know the final result when we get there.
