This Grade A engine control module was removed from a 2006 BMW X3 with only 63,000 miles on the odometer. The ECM controls the 3.0L engine with high speed synchronization capabilities and carries ID number 5WK93033. Our technicians have thoroughly inspected this electronic control unit and it is currently on the shelf ready to ship.
The engine control module is the brain of your BMW’s engine management system, controlling fuel injection, ignition timing, emissions systems, and various sensors. ECM failures commonly occur due to electrical surges, water damage, or internal component degradation over time, resulting in poor engine performance, stalling, or no-start conditions. A quality replacement ECM like this one can restore proper engine operation and eliminate diagnostic trouble codes.

Yes, most BMW engine control modules require programming to match your vehicle’s VIN and specific configuration. This should be performed by a qualified BMW technician or shop with proper diagnostic equipment.
Common symptoms include engine stalling, poor fuel economy, rough idle, check engine lights, or no-start conditions. A diagnostic scan can reveal ECM-related trouble codes to confirm the issue.
This is the manufacturer’s identification number that specifies the exact ECM variant for your BMW’s 3.0L engine with high speed synchronization capabilities. It ensures proper compatibility with your vehicle’s systems.
While this unit came from a 2006 X3, BMW often uses similar ECMs across multiple models with the same engine. Contact us with your VIN to verify compatibility with your specific vehicle.
Common causes include electrical surges from jump-starting, water intrusion, heat damage, or simply age-related component failure. BMW ECMs are generally reliable but can fail after 15-20 years of service.

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++
