Flashing Check Engine Light

My Check engine light only comes on when i am at a steady speed. When i stay at ANY speed for about 5 seconds or more, the light comes on. When i let off the gas, the light goes right away. Any help would be appreciated.

Have you tried reading the codes? To get the code you can use a simple jumper wire (or paper clip) connected at the data link connector. The connector is located beside the ashtray, pull out the tray and slide the connector cover left. Turn on the ignition and insert the wire between pin #4 (top row fourth from left) and pin #15 (bottom row second from right) for about 3 seconds, then remove. The check engine light will begin to flash a series of four digit codes. e.g. code 2123 is 2 flashes pause 1 flash pause 2 flashes pause 3 flashes then a long pause between next code. Code 4444 is no problem found. It's not hard to do, so get them & post. Also, look for leaks in the air intake boot.

I tried that, and all that happened was the light stayed off without blinking at all. whaaaa???

Some vehicles seem to have difficulty with that method. Since it's a '95 OBD-II scanners are unable to read it, therefore you need to find someone with a VW VAG scanner or simulator like VAG-COM. Several sites like VW-Vortex and Dub-Tech keep a list of people who have a VAG-COM. That is what you will probably have to do.
