• How does the CAS repair process work?

1. Remove your CAS from your vehicle.
2. Mail us your part. We do not provide a part collection service. 
3. We will recommend either a replacement or repair service. 
4. Once we have repaired your part, you can fit it back into the vehicle. All our repair and clone services are 100% plug-and-play, and no additional services will be coding will be required. 

• What is a CAS in BMW and MINI vehicles? 

The CAS serves as an antitheft alarm system and enables the start of BMW vehicles. Every time your BMW is started, the CAS module generates a random key code for safety purposes and syncs the code with the Engine Control Unit / DME. The CAS needs to pair with your key in order to start the car.

• What are the primary functions of the CAS system? 

The Car Access System (CAS) serves as:

1. Ignition Switch/Terminal control
2. Master controller for Central Locking, Comfort Access, Power Windows and Sunroof (issues enable command)
3. Actuator/Controller of Electronic Steering Lock
4. “Key” validation device and Electronic Vehicle Immobilization
5. Redundant data storage device for Vehicle Order
6. Storage point for Condition Based Service (CBS) data
7. Control of KL15 and KL 30g relays

• How to identify a failed CAS on a BMW or MINI?

Identifying if your CAS has failed and what faults are present is the first step in replacing or fixing your damaged CAS. 

The most basic tests to determine if your CAS has failed are:  

1. OBD fault codes - Most diagnostic scanners can read fault codes from the CAS. If there are fault codes relating to the CAS, it can be a good indication that the CAS is faulty. If there is no communication with the CAS, the CAS might be faulty. 
2. Visual inspection - Look for water damage or any other physical damage to the outer case.
3. Smell Test - If you can smell burned components, the CAS is likely damaged. 

If you have done the above tests or if you are unsure if your BMW or MINI CAS is faulty, we can offer a comprehensive CAS test. Once we have done a test, we can recommend the best repair option. 

• Can a CAS be repaired?

Yes, a CAS can be repaired. First, a diagnostic check is needed to be done on the damaged CAS in order to assess its repairability. If possible, a CAS can be repaired and restored. Alternatively, a replacement CAS can be installed.

• How much does it cost to fix a BMW or MINI CAS?

An OEM BMW CAS can cost between $1000 - $2000. Fortunately, The ECU Pro offers repairs and refurbished replacement units at a fraction of the OEM repair price.

A CAS diagnostic test will need to be run on your existing CAS to see if a repair can be done, or if a replacement is needed. The outcome of the CAS test will determine the cost of your CAS repair.

• What are common CAS faults?

Here are some possible symptoms and signs that your BMW may have an CAS fault:

1. The vehicle does not start.
2. Malfunction message on the iDrive screen.
3. Key not recognized.
4. The car will turn over but not start. 
5. Low or overvoltage of EWS module.
6. Mismatched Key error due to incorrect sync with the code stored in the DME / DDE module.

• Can a used CAS be programmed to your vehicle? 

Much like installing a new operating system on a computer, we can reprogram a used EWS for your BMW or MINI. Programming the used EWS will function the same way as a new OEM part from BMW. 

• Where is the CAS located in a BMW?

The BMW CAS unit is located under the steering column. Removing a BMW CAS only takes about 30 minutes. On MINI vehicles, the CAS is located under the dash, which does require about 2-4 hours to remove. 

If you order any CAS service on the website, there are detailed instructions for the removal of the parts.

• Is it possible to remove the CAS system?

Yes, to remove the BMW CAS module, you will need to get under the dashboard on the driver's side and remove the plastic cover under the dashboard (above the brake and accelerator pedal). Once you remove the panel, you will find your BMW CAS module, which will look like a black or white box.

A MINI CAS is located under the dash and requires about 2-4 hours to remove.

• How do I know what’s wrong with my CAS?

The best way to find out what fault code your CAS is producing is to run a diagnostic test on your unit. ECU Pro offers comprehensive CAS testing to diagnose, then repair, or replace your CAS to get your BMW back to running order.

• What do I need to send in order to test my CAS?

To have your CAS module repaired, you will need to send the original CAS, KEY, and DME / ECU.

• How does the CAS module control power? 

The E90 uses four relays that are installed in the Junction Box, for the purpose of switching off the power supply to the majority of the control modules when the vehicle is in a stationary status. The four relays are:

Terminal 30g - Circuit activation by the CAS

Terminal 30g_f - Circuit activation by the Junction Box control module (JBE) which monitors the following activities:

– Invalid wake-up procedures within the bus systems

– Events that prevent sleep mode (control units that keep the bus systems constantly active) Note: Since the DME constantly reads and evaluates the battery values the terminal 30g_f relay can also be switched off via a request from the DME if the start capability limit of the battery is reached.

Terminal 30 - Circuit Activation by the CAS

Terminal 15 - Circuit Activation by the CAS

•  Is the CAS module an important module in BMW vehicles? 

Yes, E90 BMW vehicles have 4 primary control modules for the systems. They include the Junction Box Electronics Control Module (JBE), Car Access 2 (CAS2), Footwell Module (FRM) and the Roof Function Center (FZD)

• How does the CAS module lock the steering wheel on a BMW? 

Locking the Steering The following procedure is necessary to lock the steering:

1. Lock request to the CAS2
2. ELV module switched on
3. Locking the steering
4. Feedback
5. Switching off ELV control module

• CAS and ELV interaction in a BMW

The CAS2 switches on the ELV module. The Hall sensor of the electric steering lock is then checked along with the “lock” conditions. On successful completion of the check, the CAS2 issues the enable signal to lock the steering.

• CAS and FRM interaction

The Car Access System 2 provides ignition switch information to the FRM.

• How do the CAS module and key work? 

The CAS assigns a personal identification code to every remote control. The CAS transfers the personal identification code to the IHKA control unit via the K-CAN.

The ID code “Key-based settings” (Key Memory) is stored in the IHKA control unit.

When the vehicle is unlocked, the remote control unit used is recognized. The settings stored for this unit are called up and executed. While entering the sleep mode (run-dow

• When does a manipulation dot appear on a BMW or MINI cluster?

Different data are stored in the instrument cluster and in the CAS when a dot appears to the left of the trip distance recorder.

The manipulation dot is indicated when, for example, there are different data stored in the CAS and cluster. If second-hand components are fitted to the car without correct data being transferred a manipulation dot will appear. If a used part is installed without the correct coding, it can lead to a doubling of the car's miles.
