This Engine Control Module (ECM) was professionally removed from a 2008 Buick Enclave donor vehicle. The electronic control unit, also known as the engine brain box, has been thoroughly inspected by our technicians and is currently on our shelf ready for immediate shipment. The part carries ID number 12607096 and was originally located behind the fan shroud.
The Engine Control Module is the central computer that manages your vehicle’s engine performance, fuel injection, ignition timing, and emissions systems. When an ECM fails, symptoms typically include poor fuel economy, rough idling, stalling, or the check engine light staying on. ECM failure can occur due to electrical surges, moisture damage, or normal wear over time, making replacement necessary to restore proper engine operation.

Yes, Engine Control Modules typically require programming to match your vehicle’s VIN and specifications. This service is usually performed by a qualified automotive technician or dealership with the proper diagnostic equipment.
Common symptoms include check engine light staying on, poor fuel economy, rough idling, stalling, or the engine not starting. You may also experience transmission shifting issues since the ECM communicates with other vehicle systems.
Compatibility depends on your vehicle’s specific engine type, transmission, and other options. Contact us with your VIN number and we can verify exact fitment before purchase.
ECM failure can result from electrical surges, moisture intrusion, overheating, or normal wear over time. Power supply issues, corroded connections, or voltage spikes from jump-starting can also damage the control module.

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++
