BMW 1 Series CAS2 Repairs
The BMW 1 series has a well known problem with the CAS2 Immobiliser system. The Immobiliser box can malfunction and cause starting issues. The Immobiliser box is most commonly located on the drivers side behind the pocket and a separate transponder near the key barrel / module.
If you’re experiencing problems with the BMW 1 Series Immobiliser system then you may already be aware how expensive this type of fault can become. Most workshops are quick to recommend replacing the module because they are not able to repair them. It’s not possible to replace the Immobiliser module with a used part because they are coded and locked to the vehicle so the common option is for a new unit which is a main dealer only part and not available on the aftermarket route. A new unit will be very expensive and will require coding and locking to the vehicle for it to become fully functional.
We offer an exclusive Immobiliser module repair service whereby we will repair your existing unit back to it’s original condition and the unit will not require any expensive coding or locking when fitting back to the vehicle.
