Can my Amp be repaired or will I have to buy new
 

Had my car in today for a fault check , there is no sound coming from my radio. The BMW mechanic said the amp is faulty. Can I have this repaired or will I have to Buy a new Amp from BMW ££££££££

buy a used one, don't buy a new one from BMW, it will cost an arm or a leg

Ive been looking on Ebay and there are a few BMW DSP Amps on there , will any of these fit my X5 or is there a certain model that I need to look out for.

Get a Loewe or Lear amp, they are newer. The Lear amps are the newest. Any DSP amp will work in your car, but I recommend you get it coded.

Here's a write-up that talks about the differences.

Ive just seen this Amp on Ebay USA http://cgi.ebay.com/ebaymotors/BMW-D...spagenameZWD2V
will this work in my X5 if I get it coded to my car.

Yes, that amp would work perfectly in your car (assuming you have DSP). Just to be absolutely sure, what year do you have?

I have a 2002 BMW X5 4.6IS with Sat Nav , will this amp definetely work in my car.

The part number for my broken amp is 65 12 6 905 119

Yes, the amp in that listing would work. Your amp is one part number generation newer, but that will not matter for compatibility. Here is a listing of all the part numbers I know about in the order they were released. The newest is at the top, and the oldest is at the bottom.

Brian, I've read through the article you linked to.. thank you!

My question is, how do you get the amp "coded" for your car? Is this done at a dealership? or is there software and a computer connection i can get?

Lastly, I'm having problems with my audio setup in my 2002 X5. I believe everything is hooked up to the amp (the PO had installed an aftermarket amp and so i've been in the process of splicing the wires back to the original harness) but i dont get any sound to the speakers. i've checked the 2 blade fuses in the trunk but is there a relay that could be the problem? when the amp is connected i get the DSP button on the nav screen so i think it's recognizing it properly.

THANK YOU for any help you can give.
