Check all door switch connections. I may be the not so obvious. The alarms work off of current sensors. If you open a door and the sensor detects a drain in current, such as the light coming on it will set off the alarm. Conversely if your battery is not holding a charge within certain range and the current drops, the alarm will think someone opened a door and will activate. Check for anything that might be putting a significant drain after the car is sitting.. Including your battery . Especially if it is old.

Do you have a sun roof? Check the drain tubes and see if there plugged. The sun roof can clog and causes a waterleak under the front seats where your alarm module is located. Pull of the mats and look under the seats for any wetness or signs of corrosion.

SOURCE: help my audi is jerking

the best i can find from the information i have is it's near the tank (not all that great information) be that as it may i would suggest it is likely a problem with the coil pack or you have water in your fuel. you haven't mentioned how it idles. to test the pack... just unplug one spark plug wire at a time ... if the engine idle doesn't change you have likely located the problem... if it is indeed water in your fuel... add a couple bottles of gas line antifreeze to your tank.... it contains alcohol and will **** up the water.


Please take a moment to rate this solution.. thanks

SOURCE: audi a4 1.8t windows, interior light wing mirrors not working

Folks, Just found my problem ...... There's a flexible conduit (corrugated rubber sleeve) between the driver's door and the door arch which contains the wiring loom for the drivers door central locking/door speaker/electric windows/mirrors etc....discovered when I slipped off the sleeve that 4 cables in the wiring loom had broken due to repeated flexing when drivers door was opened/closed over the years (2001 Audi A4). Resoldered broken wires and insulated working better than ever again dashboard back lighting seems brighter than it had been for some time? Also drivers door loudspeaker is back in action again (hadn't noticed that it had gone).
It's kinda difficult to reseat the rubber sleeving correctly after the repair job...will probably use some silicone sealant on the sleeve to ensure that there is no water ingress to wiring loom afterwards. I'm not too impressed with Audi design people after that, should have used cable that has a better flexibility rating (esp on drivers door!).

SOURCE: where do i find the starter motor in my audi a4 w reg

this is info i pulled but not sure exactly what engine you are a couple though

Fig. After the negative battery cable is disconnected, remove the wire terminals from the starter solenoid

Fig. Remove the lower starter mounting bolts . . .

Fig. . . . followed by the upper bolt, then remove the starter from the transaxle housing

0900c152800c2ab1.jpg enlarge_icon.gifenlarge_tooltip.gif Fig. Lower starter bolt locations-1994 2.0L, 2.0L ABA

0900c152800c2ab2.jpg enlarge_icon.gifenlarge_tooltip.gif Fig. Remove the upper starter bolts

Fig. Mark the location and length of each starter bolt

Fig. When the solenoid is energized the starter drive is pushed out and meshes with the flywheel to crank the engine

  1. Note the radio security code, and then disconnect the battery ground cable.
  2. Raise and safely support the front of the vehicle with jackstands.
  3. If installed, remove the lower engine shield.
The engine must be supported on 1990-97 Passat models as the starter mounting bolts also support the engine-to-transmission mounting surface. If necessary, label the small wires before disconnecting them.

On 1990-97 Passat models:

  1. To support the weight of the engine and transaxle, install the engine support Tool Nos. 10-222A and 10-222A/1, or use a floor jack (with a block of wood on the chock) to support the engine by the oil pan. Do NOT jack the car by the oil pan under any circumstances! The floor jack is ONLY to support the engine while the starter is being removed. This is necessary because the bolts that secure the starter to the transaxle are also used to secure the front engine mount to the transaxle.
  2. Disconnect the large cable, which is the positive battery cable, from the solenoid.
  3. If equipped, remove the bracket that secures the starter to the engine. On Audi A4 and 1998-00 Passat models:

Release the number 50 electrical connector from the starter.

  1. Then remove the nut for the large battery cable and remove the cable.
  2. Loosen then remove the clamp that secures the heat shield to the starter.
  3. Remove the fasteners securing the bracket at the front of the starter and remove the bracket.

Remove the starter mounting bolts, while supporting the weight of the starter.

  1. Pull the starter straight out from the transaxle. To install:
On vehicles with a manual transaxle, there is a bushing where the starter shaft fits into the bell housing. If the shaft or bushing is worn or if the starter has been jamming, the bushing should be replaced. There is a special bushing removal tool available but a small inside bearing removal tool is usually sufficient.
Install the starter into the transaxle.

  1. Tighten the related starter motor fasteners as follows:
  2. Starter support bracket, M5 nut: 35 inch lbs. (4 Nm)
  3. Starter support bracket, M8: 16 ft. lbs. (22Nm)
  4. Battery cable to solenoid, M8 nut:10 ft. lbs. (13Nm)
  5. hydraulic hose support bracket, M8: 84 inch lbs. (10Nm)
  6. Starter mounting fasteners, M10: 44 ft. lbs. (60 Nm)
  7. Starter mounting fasteners, M12: 48 ft. lbs. (65 Nm)
  8. The balance of the installation is in reverse order of removal
Check out these third-party site for more info. Yeah, we're nice like that.

My '98 Altima alarm only locks the door no more horn but it does honk when it goes off randomly, the door ajar switch on driver side was faulty( I would push with my finger did not turn off light new...

Replace battery in remote.
Check wires inside of the boot in the door jam (slice hole in boot or pull out of one end. Check wires carefully for bubbles and weak spots from cracking.
Check wires inside door jam or under dash to left hand side carefully with flashlight for bare wires shorting. Feel free to move things around under there a bit to see if things are shorting or what have you.
The fuse box under the hood - inspect underneath of it for corroded wires and or contacts - may take a bit of work to remove it from car.
See if alarm is cleared by using drivers door key as there is a switch in there for the alarm. If this is faulty then this could be your problem beyond the wires in the door jam perhaps.
You have a short or broken wire or this switch in the door is bad.
These are some suggestions of where to start.
Do it in order of easiest but I suggest the door jam wires inside boot is most typical problem especially in colder climates like here in Canada East as the wires freeze and crack after a while.
May or may not be your problem but options.
Let us know with feedback about your progress or solutions plz.

The alarm goes off periodically, t he lights flash, door locks start to clickat night the parking lights come on, my battery gets drained and it won't start

Aftermarket alarm failure it the transponder or transducer adjust the sensitivy and it will still give problem your solution is remove the alarm or diable the alarm go under the dash there you will fing the ignition harness where the aftermarket alarm installer has cut and spliced into the ignition to install a relay you will cut it and restore the original condition it simple follow the color of the wire they cut and restore it back if you use a but connection make sure it wont seperate and get you stranded you are better off soldering the connection back and wrap it with electrical tape to protect it from shorting out.

My security alarm goes off intermittingly without any apparent cause, usually 4-5 hours after I have parked it (and locked it up) for the evening. I end up having to open a door to stop the alarm and then...

When I bought my 2001 Jimmy, it did the same thing. Searched the "net" and found the solution. Open all the doors and clean the light switch buttons. Sometimes they get dirt in them. This worked for me. I've never had this problem again.
