Do you repair the factory radio, navigation and amplifier in BMW F30/F31?

We decide on cost-effectiveness individually; based on the photos and description, we will prepare an initial quote before shipping, and the final one after checking the removed module. We will repair the module only after your approval.

An initial quote is prepared on the basis of the photos sent, the make, model, year and description before shipping; we will confirm the exact price after checking the delivered, removed module. We will carry out the repair after your approval.
Do I need to come in with the BMW F30/F31 or send the removed module?
You do not need to bring the car in – we handle mail-in repairs from all over Poland, and the module can also be delivered in person by prior arrangement. Send only the removed module; removal and refitting are for the workshop, we assess the delivered unit.
What should be prepared before reporting a problem in BMW F30/F31?
When contacting us, provide the make, model and year of the BMW F30/F31, describe the symptoms and attach a photo of the front of the module and the nameplate sticker; this will allow us to prepare an initial quote before shipping. You do not need to know the model name; we will only ask for the part number if it is needed.
Repair of BMW F30/F31 radio, navigation and amplifier covers the factory BMW Harman Kardon amplifier (Harman Becker). We check the removed amplifier and only then define the scope of repair.
Which amplifier do we repair in BMW F30/F31?
In this model we repair Harman Kardon amplifiers marked, among others, B104, B263 and BE 9510. The amplifier is installed in the boot, and its designation and part number can be found on the sticker.
Symptoms of Harman Kardon amplifier failure
These amplifiers come to us after contact with moisture or after a power surge when starting the car with a booster pack. The following indicate a fault:
- no sound in the car – including parking sensor signals,
- blown amplifier fuse,
- crackling or whistling from the speakers, or silence in only some of the speakers,
- the message “No audible notifications” on the screen.
Simply drying out a flooded amplifier does not fix the fault, because corrosion on the board continues to spread.
What determines whether the repair is worthwhile?
It depends on the condition of the main board. In your enquiry, tell us whether there was water in the boot, whether you can see white or green residue on the casing, and whether there was a burning smell. Attach a photo of the amplifier and the label with the part number, as well as the car make, model and year – on that basis we will prepare an initial quote. After inspecting the unit, we confirm the price and scope of work, and we carry out the repair once you approve it. If the board cannot be refurbished, we will present a repair option involving replacement of the main board for your approval.
