i have my skoda fabia indicator problem, i went to service center they said there is a problem in BGM(circuit panle), its cost is too high, for indicator i hesitate to spend huge amount, any option to slove the issue.

What's the problem with the indicators?  What year is your car?

The indicators are driven by a solid state device within the Onboard Supply Control Module (sometimes known as BCM).

Failure of this integrated circuit is possible, but unlikely. More likely to be a fuse, connection or wire issue.  Any chance rainwater has got into any of the bulb housings?
