This engine control module (ECM) was removed from a 2003 Volkswagen Passat donor vehicle equipped with an 8-cylinder automatic transmission. The unit carries ID 4B0 906 018 DA and has been thoroughly inspected by our technicians. This electronic brain box is currently on our shelf and ready for immediate shipment to get your Passat back on the road.
The engine control module is the central computer that manages your Passat’s engine performance, fuel injection, ignition timing, and emissions systems. ECMs commonly fail due to electrical surges, moisture intrusion, or component aging, causing symptoms like rough idling, poor fuel economy, or complete engine shutdown. When your ECM fails, a quality used OEM replacement is often the most cost-effective solution compared to expensive dealer programming of new units.
At 603 Auto Salvage, we maintain over 50,000 quality used parts in stock from more than 1,100 vehicles in our Plaistow, NH facility. Our experienced team can help you find the right ECM for your specific Volkswagen application. Browse our online inventory or call us directly to verify compatibility and arrange fast shipping to your location. 50,000+ parts in stock from over 1,100 vehicles.

This ECM is specifically from a 2003 Passat with 8-cylinder automatic transmission. ECM compatibility depends on exact engine type and transmission configuration, so contact us with your VIN for verification.
Most Volkswagen ECMs require programming or adaptation to your specific vehicle. We recommend having the installation performed by a qualified technician with VW diagnostic equipment.
Common symptoms include engine stalling, rough idle, poor fuel economy, check engine lights, or complete failure to start. Professional diagnosis is recommended to confirm ECM failure.
Dealer ECM replacement can cost $1500-2500 including parts and programming. Our used OEM unit offers significant savings while maintaining original equipment quality.
While physical installation is straightforward, ECMs typically require professional programming and adaptation procedures. We recommend professional installation for best results.

RatingI'm replacing damaged panels on my 2006 Ridgeline on a tight budget so I may quickly sell it and they were so helpful and priced better than anyone else in the area. Raised a glass of scotch for these ladies! Thanks again!
Great service! The best price and condition for the Porsche Cayenne parts needed to finish the job. Radiator core support and headlight fit perfectly!
Drove from new york, Julie was a sweetheart asked questions to make sure that my ECU was the proper part number and was compatible with my manual Accord, price was phenomenal I highly recommend them for any parts your car may need. Definitely the best salvage yard around
Great experience at 603 Auto Salvage! ⭐️ The owner and employee were both extremely helpful and easy to work with. I was able to find everything I needed in one stop — about seven different items — which saved me a lot of time and hassle. Good selection, fair pricing, and friendly service. Definitely recommend checking them out if you're looking for parts. I’ll be back again! 👍🔧🚗
I had a great experience with 603 Auto Salvage Inc. The team was very helpful and quickly found the exact part I needed. They kept me informed and made the pickup process easy. The price was very fair, and the service was excellent. I would definitely recommend them and will use them again if I need parts in the future.

The customer service at 603 was great. They found the part I needed very quickly and promptly notified me when it was ready to be picked up. There wasn’t any other place in the area that had what I needed. The price was very good also. I will be using them again for sure.
I had a great experience. They didn’t just look up the part I needed they took the time to explain how to install it and made sure I understood everything. I even received a call back, which I really appreciated. Everyone I spoke with was friendly and patient, and I never felt brushed off. I truly felt taken care of. Highly recommend if you want knowledgeable people who actually care about helping you. Kristy Thanks Guys!
Drove from Connecticut to get here. Had parts for a relatively rare car that dozens of other places didn't have. I got a hood, fender and bumper cover that were in near mint condition for a fifteen year old car. They pulled all the parts for me and had everything ready within an hour. Very reasonably priced. Highly recommend
Exceptional service, large selection of parts, will come back if more Audi parts are needed. A++
