Title 12MY GEN2.1 Audio Amplifier Quiescent drain
CategoryElectrical

Symptom207000 Entertainment Systems
ContentIssue: A customer may report that the vehicle is difficult/ will not start.
Cause: Upon diagnosis the battery voltage is low and a quiescent battery drain is observed. The drain may be as a result of a capacitor fault within the Audio Amplifier Module on Trim level 2/ High Line/ Premium audio systems only. Low line audio systems that have an internal amplifier in the head unit are not affected.
Action: A quiescent drain can be attributed to one or more of any of the vehicle electrical/ electronic systems, however if the vehicle is within the VIN range below it is advisable before continuing with further diagnosis to remove the fuses for the appropriate model below and check to see if the quiescent drain is still present. If the quiescent drain is still present then continue with electrical diagnosis using Symptom Driven Diagnostics (SDD) and reference to TOPIx. If there is no quiescent drain after the fuses are removed, replace the Audio Amplifier Module, refit the fuses and check the vehicle.
L319 and L320 12 MY- Fuse 41P (5 Amps) in the Passenger compartment Fuse Box and Fuse FL11 (40 Amps) Engine compartment Fuse Box.
L538 12 MY-Fuse 11RA (40 Amps) and Fuse 10RA (5 Amps)in the Rear Fuse Box.

Hi there.

I have a Range Rover Evoque 2012 (salva2bgxch605778) with the above described symptoms. Does this mean that I have to replace the entire Amp? ("If there is no quiescent drain after the fuses are removed, replace the Audio Amplifier Module, refit the fuses and check the vehicle.").

My guarantee has expired by now and the dealer has said I need to replace the entire amp. Here in Perú the dealer has quoted me a cost of 1,250 GBP (1,600 USD) for the work -importing the amp from the UK, labor to install it and internal computer re-programming.

Can I take a different route?

a) Install a different amp in a specialized shop? This may affect the computer and other components
b) Fix the current amp? Is this possible under this problem?

Finally, an additional question. I have not been able to find out the detailed specifications of my amp. I know it is Meridian, but nothing else. Anyone can help?

In the meantime, I am driving without music and with the radio / amp disconnected.

Many thanks,

DM
