All of sudden it stopped working. Then while driving for a while it soundly prompted me that I couldn't start the pairing process from the phone. After that it worked for a bit. Then it wouldn't respond to the buttons on the steering wheel again.

I assume the HFL module is failing and will need to be replaced or disconnected.

Likely

Yep, HFL unit is officially DEAD...
Disconnect it ASAP or face the imminent downtime of having a dead battery.

Is it possible to fix it or is replacing it the only option if I want to use HFL?

If short on money you can try and "Bake It", LINK >>> Fix Your Graphics Card By Baking In Oven <<<
I´ve seen at least 2 members that claimed fixed the issue, Since the HFL unit is already dead you cant get it any worse I guess? So might be worth giving it a shot.

Thanks. I have heard of that technique before. I removed it yesterday and checked all the soldering joints. They all seem ok to the naked eye. It could be microscopic of course. If it officially dies I will try the bake fix. It was still working after I put it back together yesterday.

Well it officially is dead. The battery was dead after it sat for a few days. It is now disconnected. I will try baking it when I have a chance. I doubt that will correct it but maybe I will get lucky. For now no blueotooth is better than a dead battery.

Same thing happened to mine (on fact my battery was killed 3 times...grrrr). Tried baking it, note to self: New oven is too strong. Ended up melting mine haha. So be careful of that. Alternatiely (something less harsh iirc) is to use a heat gun.
