That there is a tool in the tool pouch to remove the headlights? It it the jointed one in the second pocket from the right.

There is always one more thing...

 

Don't forget to use the tire assist tool when changing your wheels. Makes changing wheels a snap.

 

Good one - I just put the summers on with out it!

Any more??

 

And don't forget the "hidden" diagnostics you access through your AC controls.

How do you do that and what can be reveiled?

 

The AC Climatronic unit is actually manufactured by Audi. There is some sort of serial data stream (not CAN) that allows the AC unit to display engine parameters. Works on early 996s and boxters.

To switch from F to C:
Hold down the recirculating button then push both the temperature + - buttons.

To access diagnostics:
Hold down the Recirculating & Air up buttons for 5 seconds. The + - buttons go up and down through the list of "c" codes. The center vent button switches the left display between the "c" code and its actual value. Press the Auto button to exit.

Here is a list of what can be seen:


0c - ERL
1c - Oil Temp?
2c - Inside temp. Sensor mounted in the aspirator assembly at the side of the dash.
3c - Outside temp. Sensor located inside the air inlet of the A/C unit.
4c - Outside temp. Sensor located in front grill of the radiator. .
5c - Outside temp. (matches OBC outside temp display)
6c - Coolant temp.
7c - Footwell discharge temp.
8c - Sun sensor (dash top)
9c - Sun sensor.
10c - Passenger compartment fan speed.
11c - Passenger compartment fan voltage.
12c - Temperature mix Flap command 1=COLD, 100=HOT
13c - Temperature mix Flap position
14c - Central Flap command
15c - Central Flap position
16c - Footwell/Defrost Flap command
17c - Footwell/Defrost Flap position
18c - Recirculation Valve command 1=OFF, 100=RECIRC
19c - Recirculation Valve position (feedback)
20c - Vehicle speed in kph, updating only once per second. (real speed, not speed+safety margin as in the speedometer)
21c - Engine RPM in hundreds. This too only updates once per second.
22c - ?
23c - ?
24c - Sun sensor, exterior lights switch & panel lights control (term. 58 & 58d voltage) - used for A/C panel display illum.

Which year/s for the early 996s?

 

Works on my MY00. I would suspect works for all 3.4's (99-01). Dunno if it works after 02. Please report back if you have 02+.

Does the car need to be running for the interior fans to work or just key switched to the on position?

 

Does not wrk on 3.6 engines due to updated DME.

 

997 Turbo wheels will fit a 996 C4S with 6mm spacers?

 

Thanks for the info. I am going to try it out.
