If your car won't start it could be the immobiliser but without diagnostic checks it's impossible to tell.

At DIAGNOSTICS.WALES we start with a FREE Key Test & Key Reader Check. We'll verify the immobiliser functions of these items.

EWS Immobiliser RepairsMost pre 2004 model BMW models (BMW L322 Range Rovers and Rover 75s included) have an EWS module based immobliser. We can repair these modules, we can adapt new and used modules, we can adapt engine ECUs and also create new keys.

EWS Immobliser BypassIn most cases, if requested we can bypass BMW EWS 3, BMW EWS 2 and BMW EWS 1 modules. Should your vehicle have one of these EWS variants installed we can remove the EWS completely.

CAS Module RepairsWe can repair CAS modules from the earliest CAS 1 found in the E65 to the very latest CAS 4 modules found in the latest F series. If you need a new key or you need a replacement engine or gearbox module synced up, it's not a problem for us.

On later BMW vehicles (usually with a cassette shape key) there is no mechanical linkage between the key and the steering lock. This means that the steering lock is fully electronic.

Unfortunately these are prone to faults developing with a yellow or red steering lock light. Don't ignore this warning as it leads to non start with the steering lock activated leaving the car needing recovery.

The BMW approved solution is to replace the electronic steering lock which is only available as part of the steering column at a slightly eye watering price!

Sometimes there are alternative solutions with emulators and coding works.
