Darrell/Frank: Another possibility, as with my '85 Transporter, is that the
ground for the idle switch might be bad. Mine was an internal break in the
wire. The problem was intermittent and had, I believe, been the cause of
unexplained poor gas mileage problems from the time I bought the van in 1992
till I finally had it diagnosed in 1998.
When I got it the mileage was 10-11mpg. After spending a lot of time and
money at small VW specialists I got the mileage up to 16-18mpg. Continued
like this 1992-1998 (80,000km-180,000km). Always seemed to be running a bit
rich.
After installing a brand new VWCanada rebuilt in the spring of 1998, we
shipped the van from Ottawa to Vancouver for a major trip on the west coast.
Only in Vancouver, far from home, did we find the mileage had gone down to
11 mpg. Very worried about pouring raw unburned fuel into a brand new
engine, I turned to a dealer; something I don't usually do, fearing high
labour rates and front counter people wearing white coats who usually know
less about things mechanical than I do. The job of the white coats is to
keep you from talking to the mechanic to find out if they know more than you
do and talk you into unnecessary work. They are also trained to tell you
that insurance regulations prevent them from allowing you to even see inside
the garage.
Fortunately Beck Motors in Chilliwack British Columbia is not like that. A
small dealership, they had a very competent mechanic (George) who knew how
to use the computerized equipment and went through a very methodical process
checking CO2 and hydrocarbon values against the specifications. His
methodical approach turned up the bad idle switch ground wire. The total
time was 2.5 hours or so, the total bill was $270. Price included an oil
change and filter, replacement of the Oxygen sensor with the Bosch VW
original equip. and 4 new plugs to replace the gas soaked ones. The van now
gets 21-22 mpg (the best I think you can expect) and runs smoothly.
Given that I'd spent 3 times that amount on about 5 different occasions
trying to get other mechanics to fix it, I think this is one of those
(probably rare) occasions when going to the dealer makes good sense. I have
no interest in Beck Motors - just think credit should be given where it is
due, and think that sometimes going to the "right dealer" can make sense.
I 'm wondering if a rating of dealers is something useful that the list
members could do for one another to steer people to the good guys in the VW
garage business. We wouldn't have to say negative things about others just
list ones we've found to be outstanding - especially for certain kinds of
work.
