I have been told by my BMW mechanic that my amp in my 2004

Customer Question

I have been told by my BMW mechanic that my amp in my 2004 645ci has had it. He did do a diagnostic check & it came up as fault in the Amp. But that's all. All I get is a dull tone through the speakers & NO sound through the rest of the system ie no warning tones etc. I have researched them online for around £350.00 & will replace myself. Is this rite in your opinion.
Thanks Jerry

Steve :

yes this sounds perfectly correct

Steve :

no sound and amp fault in the computer points to a bad amp.

Steve :

plus, they are common to fail

Steve :

if you replace the amp yourself, it may require programming to work

Steve :

you can try replacing it and see if it works

Steve :

if not, you will need to have it programmed by a bmw main dealer or shop with that ability
