After replacing the clutch my radio is switch off .
How to check the code if I have no instructions?

 

From the FAQ's and Guidelines - READ BEFORE POSTING!:

 

If your car came with any paperwork at all, flip through it. When I bought my car, it included a plastic car (the size of a credit card or driver's license) with the radio code on it.

If you want, you can also post the serial number from the radio on here, and someone might be able to run the numbers and send you the code. (it's happened before)

 

should be in the glove compartment box or call the service technician at your local dealership.
