Car Radar for BMW 3 Series — Common Failure Points
Car Radar on the BMW 3 Series is one of the few items where the specification is not a matter of taste. This common failure points covers what has to be checked before the part is bought, what the installation actually involves, and what has to be documented for the vehicle to stay insurable and road legal in your market.
Failures here are rarely dramatic. They are reorders that did not match the approved sample, or packing that arrived crushed at the port — the kind of problem that shows up at the worst possible moment.
