Top 10 2000 Audi A4 Questions & Answers

I just had the same problem and read on another post how to fix it. Unlock your car, open and close all the doors, and lock it manually with your key. It worked.

I agree with Guest - he's got all the info straight.

The easiest way to do it is to pull the headlight out of the car. This isn't hard, but you'll have to have a T30 Torx bit to do it. There are three bolts that secure the headlight. Two are on top of the headlight - you'll see them right up there on top when you open the hood.

The third is harder to find. Look where the outer upper corner of the headlight meets the top of the fender, above the corner indicator. There is a lip on the fender that runs all the way back to the base of the windshield, where the edge of the hood sits when it's closed. There is a round hole in that lip near the headlight (just behind it). Shine a light down in there and you'll see the third Torx bolt. Take that out and you can slide the headlight assembly forward. You shouldnt' have to take it fully out of the car, just take the bolts out and move it forward.

Then remove the dust cap on the back of the headlight, pop the connector off the bulb, undo the spring clip holding the bulb, and remove it. Install the new bulb (wipe down the glass portion with your t-shirt to get any skin oils off it, as they'll burn it up quickly), and then reassemble in the reverse order.

Your dash has what is known in the trade as a dry solder joint in the instrument cluster it will have to be repaired by people whom specialise in this work.
You could try BBA remanufacture as they do a lot of this type of work for us.

On an Audi with the simple alarm system (no motion sensor and no disarm button on door centerpost) the fuse cannot be pulled without also disabling the power door locks. You may also have problems with your license plate, back up or fog lights. I tracked my car alarm and light problem to the wiring to the trunk lid on the driver side. The wiring is enclosed in a sleeve and attached to the two parts of the hinge with a free section in the middle to bend as the trunk opens and closes. Inside this bending section I found the separate wires either broken completely or the insulation cracked, creating intermittent shorts and activating the alarm. I reconnected and taped the insulation and the problem was solved.

First time you might check the thermostat operating.

Heed of antifreeze coolant temperature!!!

The thermostat location for a 2000 Audi A4 1.9 TDI is on back of the alternator at the bottom side of the bracket.

IMPORTANT NOTE: It is NOT necessary to replace the alternator if you want to change the thermostat !!!

Thermostat checking:
1. Cold engine. Start up the engine and watch of the water temp indicator. After first value 60 Celsius Degree you still warm up the engine until the lifter (pointer) reach 80 C deg. (second mark after 60 C deg.). At this time you let engine running at idle speed and check with your hand the thermostat plastic housing and hose temperature in bottom left side of the engine. Heed of alternator driving belt and ventilator fan !!!
2. If the thermostat is good the hose must be cold until the water temp indicator reach almost 90 C deg.
3. The thermostat opening temperature is 87 C deg.
4. If the hose is already warm the thermostat is out of order.
