BMW 740 DME / ECU Location
SYMPTOMS OF A BAD 0261207106 ECU:
When you choose the repair service you send your unit to our location. Once we receive the unit, we test and diagnose the unit. Then we repair it, if it is needed, and we send it back to you with a report of what caused the unit to go bad.
When sending your unit for Repair, send us the ECU/ DME Set:
Where is the EWS Located?
HOW DO I SEND THE ECU FOR REPAIR?
Step 1: Click the orange icon "REPAIR FORM"
Step 2: Fill out the form.
Step 3: Print the email confirmation.
Step 4: Pack your ECU Set securely.
Step 5: Send the repair form along with your ECU Set .
TURN AROUND TIME FOR THE REPAIR:
The average time for the repair process is 3- 5 days once we receive the ECU Set at our office.
First, we send you an rebuilt ECU from our stock. Once you receive our ECU, you send us back your damaged ECU core. For your convenience, we include a prepaid UPS Return Label in the box.
1. We will need your car's VIN Number to program the ECU.
2. Transmission type; Automatic or Manual.
3. DME to EWS alignment/synchronization needs to be done on this ECU with the Exchange Service.
This is a simple 5 minute process which "marries" the DME to your car.
Your local independent BMW mechanic or dealership can do this in 5 minutes using their BMW Scanners.
What's the "Core Charge"?
The CORE CHARGE is a deposit that we collect to ensure that the exchange is completed. When we receive your ECU core at our office, we refund the core charge back to your credit card.
Your old ECU must be returned within 5 days of the delivered date in order to receive the refund of the core deposit . You may be subject to additional charges, in addition to a canceled warranty, if you do not return your old ECU within 5 days of receiving your new rebuilt ECU.
ECU's returned in NON-REBUILDABLE condition, such as HEAVY WATER DAMAGE, FIRE DAMAGE or PREVIOUSLY MANIPULATED ECU'S; may receive a partial refund, or no refund at all .
*FOR INTERNATIONAL SHIPMENTS ONLY* There is an additional $100 Core included in the shipping charges which count towards the core charge deposit. Once we receive the ECU core back, you will be refunded the original core charge plus the additional $100.

General Technical ECU Troubleshooting Guide
In the industry there are many BMW ECU programming. We wrote a guide to help answer and give you solutions to some of the most commonly asked questions.
We have reverse engineered these ECU's and developed proprietary Equipment that allows us to Re-program used ECU's to your car's VIN Number.
Because if you install a used ECU in any BMW, the VIN number and "Rolling Code" will not match, and it will prevent the car from starting.With a used ECU the car might crank, but it will never get the "permission" to power the fuel pump and send the spark signals.
BMW's have the EWS Module (anti theft device) that has a password feature called the "Rolling Code" which changes between the DME and EWS every time that the car is turned off. This makes it virtually impossible to swap used ECU's between BMW cars.
"NO". Our Exchange ECU's will be programmed to your BMW's VIN number and correct application. However, due to the fact that the EWS systems have a random "Rolling Code" we can't guess what this random code is. Therefore, we reset this feature to make the ECU "blank".
In order for the rebuilt ECU to work in the car, a ECU to EWS Alignment/Synchronization has to be carried out.This is done using a BMW scanner like a GT1, ISTA, Autologic, Launch X431,Baum Tool DS2021and others. It takes less than 5 minutes to "MARRY" the ECU to your car, and once that is done the ECU is ready to start in the car.
NO. ECU re-programming is not required because most repairs are done on the hardware parts and not on the software programming. Once we repair your unit, it will be 100% "Plug and Play" already tested in our actual Tester vehicle.
