1999 Audi A4 Climate Control Removal/Installation

Does the Climate control Unit have any bolt that must be removed prior to it's removal, or does it pull straight out. Should I disconnect the battery before removing it? Thanks!

    Is changing the a/c control a simple swap out or is it much more involved? It appears straight forward from the looks of the back of unit...

You have to remove the trim panel around the stereo/climate control to expose the screws that hold it in place. Once you do that, and the screws are removed, it pulls straight out and unplugs. No need to disconnect the battery and no tricks to it once it slides out.

  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.

NOTE The engine must be supported on 1990-97 Passat models as the starter mounting bolts also support the engine-to-transmission mounting surface.
  1. If necessary, label the small wires before disconnecting them.
  2. On 1990-97 Passat models:

  3. On Audi A4 and 1998-00 Passat models:
    1. Release the number 50 electrical connector from the starter.
    2. Then remove the nut for the large battery cable and remove the cable.
    3. Loosen then remove the clamp that secures the heat shield to the starter.
    4. Remove the fasteners securing the bracket at the front of the starter and remove the bracket.

  4. Remove the starter mounting bolts, while supporting the weight of the starter.
  5. Pull the starter straight out from the transaxle.

To install:

NOTE 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.
  1. Install the starter into the transaxle.
  2. Tighten the related starter motor fasteners as follows:
  3. Starter support bracket, M5 nut: 35 inch lbs. (4 Nm)
  4. Starter support bracket, M8: 16 ft. lbs. (22Nm)
  5. Battery cable to solenoid, M8 nut:10 ft. lbs. (13Nm)
  6. hydraulic hose support bracket, M8: 84 inch lbs. (10Nm)
  7. Starter mounting fasteners, M10: 44 ft. lbs. (60 Nm)
  8. Starter mounting fasteners, M12: 48 ft. lbs. (65 Nm)
  9. The balance of the installation is in reverse order of removal.

NOTE Be careful not to over tighten the battery cable connection. The metal is soft and the threads will strip easily.
  1. Lower the vehicle from the jackstands.
  2. Connect the negative battery cable and enter the radio security code.

1999 Audi a4 climate control replacement

Nope - once you have the trim panel off and can unbolt the CC head unit, just slide it out, unplug the connectors, plug in the new unit, and reassemble. Nothing more to it than that - no diagnostics, codes, or setup needed.
