    Can anyone tell me if and how the yellow abs light and red brake light are related to the ac on a 2003 tdi. I know this sounds silly,…but it seems almost every time I hit the ac button, the abs light comes on steady, the brake light flashes, and I get three beeps. This does not occur every time and other than what I described seems totally random and intermittent. The fluid level is ok and the sensor is plugged in. The parking brake is not on

    Neither ABS lights should come on when you turn the AC on. You need to find someone with VAG-COM\VCDS to give your car a scan.

    I've never heard of Nepa where is that?

    Hi Keith,

    Thanks for your reply. Unfortunatly I don't have easy access to VAG. NEPA is local slang for Northeast Pennsylvania.

    Well now we know your in the States I believe Autozone with do you a free VAG-COM\VCDS scan with the hope you buy something of them are there any Autozone's in your area?

    Just add PA after Nepa then we all know where your from?

    Hi Keith,

    Thanks again, AutoZone only offers free OBDII scans. At least in my area they don't invest in VAG diagnostics.

    Well I'm only going by what YMZ said on a few threads.

    Even an EOBD II scan is better than nothing.

    Or you could search in your area Vag-Com Locator Map

    FIXED. Connector on fuse block on top of battery was loose.

    Geneo,
    despite it not making sense that is absolutely what happens when a fuse goes bad. It happened to me when I first got the car.. I put the A/C on and the brake light came on and the panel made that annoying noise when something is wrong.

    I traced it back to a blown fuse in the fuse panel. Electricity will find the easiest path to where it wants to go and in our cases it went via the brake circuits I guess.

    Glad you found and fixed it.. it had me scratching my head when it happened to me.
