Re: 5kq instrument questions
It seems like a lot of us bought our 5kcstq's with nothing showing on
the temperature gauge. You almost certainly need a new multi-function
temperature sensor. It's a four-pronged (well, only three on the newer
ones) brass-bodied sensor that screws into the underside of the upper
coolant flange, at the front of the block. Scott Mockry's excellent site
(www.sjmautotechnik.com) even has a picture of this sensor, IIRC.
I believe list price is something like $80. You should be able to get it
from the Parts Connection (www.thepartsconnection.com) or from Linda at
Carlsen Audi (phone number on the list's web site) or others for a
little over half that.
I don't believe there is a trouble code for the MFT sensor, so it's
correct that you're seeing 4-4-4-4 from the diagnostics.
As for what else to look for in maintenance... hydraulic leaks (steering
rack, pump, hoses) are very common. I happened to buy mine with the same
mileage as yours and I needed a new clutch in short order, but they
usually last much longer than that. A stiff pedal is symptomatic of a
clutch throw-out bearing on its way out, which is the common failure
Hope you enjoy the car!
