I just bought a car and the locks, stearing wheel buttons, windows, and sun roof do not work unless i have the key in the door. i tried to reset the module by connecting the positive and negative together for 30 sec but the only thing that did was turn on the anti theft on the radio can anyone tell me where the module is so i can check that out PLEASE?

 

start with telling us year and model and a better description of your problem considering that doesn't make much sense, plus why would you buy a car like that was it free?

 

B5s have a central locking pump and CU in the rear on the pass side behind the lining. You likely have water entry in the trunk are causing issues like you've described. Pull the lining and inspect the harness for corrosion and water entry.

 

thank you for the info! Its a 1999 audi a4 2.8 quattro.also along with the other problems, the abs light is on and the brake light is blinking in the dash. this guy owed my a bunch of money so he gave me this car "this is such a great deal for you".........a$$hole.

 

DO b5s even have steering wheel buttons? I never seens one

Also, ABS with blinking brake light means your module is most likely fried, cheapabs.com, 100 bucks and its fixed

 

The buttons are for the tiptronic, you likely need to repair or replace the tiptronic shifter gate in the center console. If the brake light is flashing, you likely have a bad communication code from the ABS CU, but you'll need to read out the codes before you throw parts at it.

Where are you (and the car) located?

 

I live in oregon. This is such a nightmare, i have been wanting an audi for so long and now that i have one i have problem after problem. so are you saying i should have someone with a scan tool run it and see what codes pop up? thank you all for all of your help!

 

It's always good to get a reading of all the codes in the car to give you an idea as to what's going on.

Most of us use VAGcom as a DIY home scanner, available here: http://ross-tech.com/

If you plan on working on the car yourself, another good idea is to purchase the Bentley Repair manual, also available on Ross-Tech's website. Don't waste your time or money with Haynes or Chiltons for Audi. Skip right to the Bentley.

It sounds like you've inherited a basket-case. Though it's gonna be an up-hill battle, it's not beyond repair. Check the stickies, the FAQ, and check out Audiworld's tech section for help. http://www.audiworld.com/tech/

Good luck!

 

Or you just keep replacing parts until the lights go away

If you having these problems now.... i can just imagine the amount of work needed under the car.
