Peugeot NAC Wave 2: Bluetooth Problem Diagnosis and Solution
In the European car park, particularly on popular models like the Peugeot 2008 II, the NAC Wave 2 navigation and multimedia system plays a central role. It is the gateway to essential navigation functions, but also to your client’s audio and telephone comfort via the Bluetooth connection.
For you, the automotive repair professional, a client reporting a Bluetooth failure on their NAC Wave 2 represents not only a technical malfunction but also a noticeable deterioration of their driving experience. A connection failure can quickly generate frustration.
This technical article guides you through the precise diagnosis of Bluetooth failures related to the NAC Wave 2 and shows you how to isolate the problem, positioning you as the trusted expert for your client.
Understanding the NAC Wave 2 System and its Challenges/Issues.
The NAC Wave 2 (New Automotive Communication) is a multifunctional multimedia unit manufactured by Continental, integrating navigation, radio, management of audio sources (USB, Aux, Bluetooth), and vehicle interfaces. It equips a wide range of PSA vehicles, including the Peugeot 2008 II, as well as other Citroën and Opel models.
Role of Bluetooth in the NAC Wave 2
The Bluetooth module is a critical sub-system of the NAC Wave 2, managing phone pairing for hands-free calls and audio streaming (A2DP). A failure in this module, whether software or hardware, directly impacts user satisfaction.
Typical Manifestations of Bluetooth Failure
The most frequent reports we deal with in our workshops for the NAC Wave 2 concerning Bluetooth are:
• Inability to pair a new phone: The on-board system no longer detects any Bluetooth devices, or the pairing attempt systematically fails.
• Intermittent disconnections: The Bluetooth connection is established, but it cuts out randomly, making calls or audio listening unusable.
• Audio quality problem during communication: The sound is choppy, crackling, or the client’s voice is not transmitted correctly, without the microphone or speakers being at fault.
• The “Bluetooth” menu is grayed out or inaccessible: The module appears to be inactive or undetected by the system.
• Other recurring associated failures: Although distinct, more general problems like a black screen, the system constantly restarting in a loop, or a total audio failure can be linked to a wider failure of the NAC Wave 2 affecting the Bluetooth module.
Simple Checks on the Vehicle Side
Before concluding that there is an internal problem with the NAC Wave 2 unit, a few checks on the vehicle and client side are essential for a rigorous diagnosis:
1. Client Device Check: Ensure the client’s phone is not the problem (Bluetooth activated, visible, test with another phone, deletion and re-pairing on the phone).
2. Software Update: Check the software update status of the NAC Wave 2. A known bug can sometimes be corrected by a manufacturer update.
3. Fuses and Power Supply: Check the fuses related to the multimedia system. A bad power supply, even temporary, can generate software errors.
4. Electronic Diagnostic (Diagnostic Tool): Use your diagnostic tool to read the specific fault codes (DTCs) for the NAC unit (telematics or car radio unit). Search for codes indicating an internal failure of the electronic board or a module communication error.
When to Suspect Internal Failure of the NAC Wave 2?
If the external checks (fuses, power supply, client devices) are good and the fault codes point to an internal electronic failure, or if the symptoms persist after a software reset or update, there is a strong possibility that the internal Bluetooth module of the NAC Wave 2 is at fault.
To guarantee a successful repair and the application of our warranty, it is imperative that the NAC Wave 2 unit is never opened or tampered with by the garage or the end customer.

What are the recurring problems with the NAC Wave2 other than Bluetooth?
The frequent breakdowns include black screen, boot loop restarts, audio faults, and GPS or radio reception problems.
If I disconnected the battery, did that solve the Bluetooth failure?
No, if the failure persists, it indicates an internal hardware problem; the disconnection only fixes simple software errors.
My diagnostic tool indicates no specific fault code. Should I still send the NAC Wave2 for repair?
Yes, if the symptoms persist. Our specific test benches can confirm an internal failure that the diagnostic tool did not detect.
Why is Reparlab repair more advantageous than replacement with a new part or a standard exchange?"
We correct the root cause of the breakdown for increased reliability, with a 24-month warranty, at a fixed price, and in compliance with IATF standards.
