1994 Audi Quattro 90 engine wiring harness to TPS

Hi, we're new to the forum. We recently replaced the head gaskets on a 94 Audi 90 Quattro. The job itself went smoothly, but, we're having a heck of a time finding any wiring diagram for the engine. In particular, we're trying to locate the TPS plug. We somehow misplaced it in the engine so we're trying to find a good wiring diagram to show us what harness and location that the plug would be coming from. Any help on the diagrams is very much appreciated. Oh, engine is a 2.8 V-6. Thanks in advance.

    I wasn't looking for another engine. What we did was replaced the head gaskets and customer decided on up grading. So we installed custom ground cams and ported and polished the cylinder heads while it was apart. Upon putting the engine back together, during installation the TPS plug somehow got pinched under the throttle body. I got it out and installed it where it belonged and the car ran exactly the way it was supposed to.

If you want a good selection id try a parts locator. One place that can find you a good short or long block for a [URL=""]Audi A4 engine[/URL] is [url=]TEXAS Junkyards[/url], Junk Yards in TEXAS TX salvage recycler. They have a link somehow to multiples of thousands of recycling centers and will locate the best one for you.

1998 audi a6 2.8 quattro tiptronic doesnt work but auto still fine?

Google it - Check this LINK. If your horn or other steering wheel controls do not work, it's likely the clockspring - the device that transmits the inputs from the steering wheel into the wiring harness under the dash. Pray it's not, otherwise your Audi tech will be buying himself a new S4.

I have a 99 Audi A6 Quattro and recently got the radiator, transmission hoses, filters, gaskets and transmission fluid changed. Now, the car doesn't even move, even when a gear has been selected. What...

It is most likely that it is the transmission, it sounds like you didn't put fluid enough. or something is restriction the fluid flow to the torque converter which is located between the engine and the transmission, it replaces the clutch in a manual transmission. The wiring harness to the transmission may have been unplugged when you did this. make sure it is plugged to the transmission, and the transmission is full of fluid.

1994 Audi A80 2.6E has got water getting mixed in with the oil some how, can anyone help me?

Coolant from the car's cooling system will generally escape into the oil passages (and into the cylinders) under pressure when you have a blown head gasket on your engine. You will also notice that you will need to be topping up the coolant level.

This is not a reliable model and the head gaskets on these engines are prone to failure if the cooling system is not completely flushed out and new coolant added at least every 2 years. The head gaskets will also blow if the car has been operated when the engine is overheated - such as when overheating is caused by allowing the coolant level to drop too low.

In your case the symptoms you have described do point to a blown head gasket. If you inspect the coolant in your cooling system when it is cold you will probably also see evidence of oil in the coolant fluid.

You need to get the car to a reputable audi specialist, who is familiar with the problems with these engines, to check it out for you.
If you have a blown head gasket, as it appears, the repair costs will be quite expensive as are most mechanical repairs on German cars.

How do i change the sump on my audi a6 2.8 quattro

Remove the large plastic body panel under the engine, if it is still there. The oil pan is about 14in x 12in square with a round sensor in the middle. Drain the oil, disconnect wires, remove all 20 or so bolts. Clean gaskek surface and silicon new gasket in place. replace the bolts, but only hand tight. Let the silicone set for 2 hours, and then tichten to factory spec, about 15in/lbs
