Can a diversity antenna be repaired/reconditioned?
 

I am almost 100% certain my diversity antenna is kapoot. I have no more AM band, my FM band has poor reception and my WB is gone as well. The FOB key still work.

Question, can a diversity antenna module be salvaged/repaired/reconditioned or is it a straight out replacement?

Thanks.

replace it, you will be pleased you did it. Depending on the age of your car that part has received so many updates.

My diversity antenna was faulty. After looking at the curcuit board with a magnifying glass I could see there was corrosion on there. I cleaned off the corrosion and shone a torch behind the curcuit board and looked from the top and I could see some of the copper traces had corroded away. There are a few tips on how to fix them on YouTube.
I fixed mine, although very fiddley.
You could probably get it done professionally and save yourself a few quid.

Thanks for the comments and tips. Now that the weather has dried up a bit, I have the AM and WB band again. My FM reception is also better. I may wait a bit before taking action to replace it while monitoring it.

Make sure at least the foam spacers are installed outside the module. Look up the bulletin if you don't know what I'm talking about. It's supposed to keep more water out of the module, though my experience is that it still gets in even with them!

If you're going thru the trouble of opening up the case of the module, then try to silicone the edges to minimize further water ingress would be my tip to you.

Yes I have the service bulletin. However, all of a sudden my antenna is working again. I will probably hold off for a little bit and monitor the situation. By the way, where in Canada are you located?

Mine (module) died about a year after it was replaced, and when I opened it up, found the spacers were there, and they had even put some silicone around the edges of the plastic case, but it was still wet inside... :( So that's why I'm not so sure they do much other than possibly delay the inevitable. Crossing my fingers the last replacement of a month ago will last longer, as I'll be out of warranty then.

Ouch, that sucks. What is most upsetting is I have 1 month remaining on CPO and they will not change the diversity antenna under CPO :angry:. Nevertheless, it is working now so I will hold off on the expense...

Hmmm... I was debating whether to buy an extended warranty or not. If it doesn't cover that, then what the heck is it good for? That's odd. I was worried there would be all kinds of exceptions to what's covered.

I heard most people get Coverage One thru the dealers, as an extended warranty.

So I'm thinking maybe I'm better off just putting aside my money instead of buying the extended warranty.

And this is what the US people get I think:

US buyers have better coverage than we have. I will try one more dealership (via a contact) to see if I can get it replaced under CPO. The fact that it is working again makes me believe that it can be fixed instead of an outright replacement.
