Indeed, these are very helpful videos. I am also looking forward to the
resolution on this one, Hopefully Ben records and uploads the diagnostics
on that as well. S'il vous plait ???
At the core of all this though, there is a problem I am wondering how to
solve... The telemetry that VW designed to monitor conditions in our
engines is TERRIBLE!!! And as it ages it is not getting better.
This past week I developed a small leak in a coolant hose. The hose in
question was the one that feeds water from the pump into the thermostat
housing. The only warning I had was when the low coolant light started
flashing. The engine temps came up a little, but not a lot. I pulled over,
checked the coolant level and it was low. I could not see a leak because
the coolant level had already dropped below the thermostat hose, and I had
stopped the engine.
I didn't have any coolant aboard, so I got back on the highway to get off
at the next ramp. The temps came up a little, but not far. I got off the
highway, and the engine stalled, right across the road from a service
station where I was able to buy some coolant. I put it in the van and
immediately saw about $10 worth go right out through the torn hose.
I restarted the van and limped another 100 yards to a safe parking spot
and removed the hose. Luckily for me I could read the part number stamped
into it. I called the local NAPA, about 2 miles away and they didn't have
the hose in stock, but they were kind enough to call their supplier, who
had it to them in just over an hour. Did I mention that this happened on
the first major snow day of the year in Toronto? I got the hose installed
and added another gallon and a half of coolant and the van has been fine
since.
BUT WHY WHY WHY WOULDN'T VW PUT A TEMP SENSOR ON THE ENGINE, INSTEAD OF IN
THE COOLANT????
Which reminds me... Is there a list vendor who sells a sender for a VDO
oil temperature gauge? I am thinking I will should get that installed
sooner, rather than later. This *might* have helped me avoid risking
damage to my engine.
