Repair of the Volkswagen Multivan T5 radio, navigation and amplifier includes the factory Dynaudio AMP600 amplifier. Below we describe its symptoms and how we check it.
Symptoms of Dynaudio AMP600 amplifier failure
Signs of a fault in this amplifier may include:
- sudden crackling in the speakers that appears at random and interrupts the music – over time the problem gets worse, until there is complete silence,
- the battery draining while parked, because the faulty amplifier does not switch off completely,
- loss of communication: the unit does not respond, and computer diagnostics show communication errors.
How to identify the AMP600 in a Multivan
The rating label, above the barcode, bears the AMP600 marking. A photo of this label allows us to confirm the amplifier model before dispatch.
Checking the amplifier itself
You send the amplifier only. We connect it to a test setup with a radio, CAN bus and dedicated power supply to confirm whether the fault lies with this unit. If the fault is confirmed, we will contact you and proceed only after your approval. If the amplifier turns out to be working properly, we return it and advise what to check in the vehicle.
AMP600 failures have two main causes: wear of electronic components after years of use, and voltage spikes caused by a weak battery, jump-starting or booster cables. We also accept the factory radio and navigation system from this model – describe the fault and attach a photo of the label.
Frequently asked questions and answers
Repair of Volkswagen Multivan T5 radios, navigation systems and amplifiers: enquiry, module dispatch and quote.
How can you tell that the Dynaudio amplifier in the Multivan is failing?
Signs of a fault may include sudden crackling in the speakers, followed over time by silence, battery drain while parked, and communication errors with the amplifier in computer diagnostics.
Can I send the Multivan amplifier even if I am not sure it is the cause?
Yes. We first connect it to our test setup and check whether the fault lies with the amplifier. If it turns out to be working properly, we send it back and advise what to check in the car.
Why does the battery in the Multivan discharge while parked?
One possible cause is a faulty Dynaudio amplifier that does not switch off completely and draws current with the car locked. We confirm this after checking the removed unit.
How can you protect the Multivan amplifier from recurring damage?
Keep the battery in good condition and do not jump-start the car with a booster. Voltage spikes from a weak battery or jump-starting with leads can damage the amplifier electronics.
Do you accept a Multivan amplifier after an unsuccessful repair elsewhere?
Yes, we verify the condition of the unit during the inspection stage. We price a Dynaudio amplifier that has been tampered with before on an individual basis, after checking the module.
