Title: ECU issues
Post by: rbroederer on August 10, 2016, 02:06:46 PM
New to NefMoto. I have a 2000 Audi A6 2.7T Quattro Tip. The car runs great...for 5 minutes. Then it goes into limp mode and gets an error message that says "ROM error". If I drive the car and turn it off every 4.5 minutes it runs great. I talked to the people BBA Remanu and they said they couldn't fix it. The ECU I have is a Bosch 4B0 907 551 L. I recently bought a used one and was going to have it programed. Any thoughts.

Is the ECU stock?

I say definitely ECU. Not too much hassle to swap it out and see. That would be my first step.

I have a used ECU. Do I have to have it programed for my car? If so, where can I send it? The car is in Las Vegas Nevada. Thanks in advance.

Have you read any of the flashing threads?

I came to the site looking for answers and wasn't sure I had the right place. I will look at the flashing threads. My problem is I am in Ohio and I had to put the car into storage in Las Vegas. Now I want to fly in and pick it up. I want to make sure I can plug and go. Sorry if that sounds lazy...

You may have immobilizer problems if you try to plug and go an ECU from another car...
