I replaced the ECU from a donor car. It was a wreck.. Now I have an air bag light on the instrument cluster. I could take the cluster out (again) and put tape or paint over the LED, but wondered if there was a way to switch it off..

What would the likely cause be? I have tested voltage (gets 5 volts). I thought it was supposed to receive 12, but when I supply it with 12, I get a different code indicating voltage too high. Disconnected that wire and we're back to the original P0030 code. What should I check next?

OK, I went to Pick N Pull and snagged a brain box and MAF sensor from an 04 Golf. Now it starts and stops right away.
I see a light on the dash that depicts a car in profile with a key running along the running board. Is this a security issue related the ECM swap?

Common causes for ABS light illumination?

I am hearing an air noise under the dash booster. (brake booster )..... Moving the silencer (foam seal) may reduce noise level. Might fix in this way?

Whenever it is plugged in to a code reader it just says no communications

It sounds like the engine struggles between 3000 and 4000 RPM when on the highway at about 60-75 mph. The problem does not occur until I am on the highway. It almost seems like I run out of gear and my car wont shift again to a higher gear. The steering wheel also shakes at this speed but I believe that is because I need an alignment. Are all of these connected? or what can it be?

-On the D position the car remains with the second gear all the time; it never shifts up or down as required, except for R.

Well it leaks.

Any idea how much this will cost to fix ?

I recently purchased my 2003 VW Golf and a few weeks ago changed the oil after noticing it was time to do so (I did it myself). I used the proper oil and such, but now the oil indicator light keeps coming on, usually 10 minutes into my drive, flashes and beeps, but never stays on (just flashing). Is this a malfunction in the car computer or is there something wrong with my oil (I rechecked it, clear, full and fine). Thanx

wondering if the engine would be damaged by making this change now on an 03 model.....
