Hi.. I had a water leak in my trunk and my amplifier was blown by it. When i serviced the car at the dealers they also confirmed that the amplifier was shut. I purchased an amp from ebay which costs much less than the dealer price and it was taken out from a 2010 335i. mine is 2006 330i. I plugged the amp yesterday and still there is no sound. Does it need coding or something else? 6 months without music in the car is a long time.

No coding needed, I sold an amp here before. The guy had the same exact issue (water in the trunk) and new amp started working right away.
Confirm that the new amp is Logic7, take a look at the sticker. How much you paid for it? they go for $700-900.

I paid $592 with shipment costs. But i still dont get any sound. i have the radio on i can change the channels. The amplifier is working i can see the light in it . But i dont hear any sound. what else can i do..thanks..again the amp is a 4 year newer model..and yes the amplifier is logic 7.

Honestly no clue, check all the connections I guess.
There's also MULF2 and TCU units under carpet. They are irrelevant to sound but the optical connection passes through them, so if one of them is dead then there might be no sound.

the dealer ran diagnostics to find out whats wrong. he said everything else is fine but the amp.

I guess take it back to them, see what they say now.

The Logic 7 systems are not the same from 06 to a 2010. The processing is different. make sure the part numbers are the same.

Are your sure your MOST bus in not broken, complete loop ?

The amp from 2011 335IS was working in my 2007 (12/06 build) car just fine.
It wasn't even Logic& amp, it was "Harman Kardon Top HIFI", which is the same thing really.

Interesting.

Have you checked the fusebox? I know when I installed my aftermarket amp, during the install I found that there was no power being supplied to my amp once I tested it. After checking the fusebox, i found that fuse 34 (on an 07' 328xi) was blown and as soon as I replaced it with another 30 amp fuse, the amp turned on immediately.

Anyluck on this I'm having the same issue. Bought a new amp and still no sound???

[alex76]

count me in, got the similar issue with my logic 7/2006-330i. Dun know how to deal with it since buying an used logic 7 off from ebay sounds very challenging!

[Cali FlyBoyZ]

guess i can add my name to this list... my car basically was flooded with water near the amp and now i have no audio at all. i will try to swap an amp and see if that works... are there any after market amps that would work?

Did you get a fix for this? I also swapped a amp but no music I get sound, door chimes, my bluetooth works fine. Just can't get any music I actually can't select Radio, Sat, etc from the idrive. The only highlighted option in my idrive is AUX but even if I connect my ipod still no sound. the most loop is complete as I mentioned my bluetooth is working flawlessy. Any sugession would help.
