I had the RR Evoque since new. It has 27,200 miles. I had replaced the original battery 17 months ago with a NAPA AGM perfect fit battery for the Evoque. Now after 17 months the battery has died again and it was still under warranty so I got a replacement NAPA AGM battery.

After installing the new battery the car starts right away except now I have a Charging system fault warning and a washer fluid warning. I topped up the washer fluid but still get the message. I tested the battery it was at 12.7 volts before starting first thing in the morning after sitting all night. I then started the Evoque and when the A/C was on and all the lights on at idle it charges at 14.02 volts.

Here is what the dealer had to say when I asked about the software update.

"In regards to your question, first I thank you for providing me the complete VIN as this is what I would need to research any and all open campaigns for this particular vehicle. Remember that when reading information online it gives you information in general and not specific to your vehicle.

For your vehicle specifically, I have checked the Land Rover system and see that there is only one open campaign which we will need to schedule. The campaign is for the Supplementary Restraint System warning lamp on, even if this lamp is not on at the time we will need to update the vehicle software for this concern.

In reference to the battery concern, it is highly recommended to use OEM battery or in your case you may also use compatible AC Delco. The thing is that prior to installing the battery it should be fully charged and the CCA should match the original (700-850CCA) as the vehicle is equipped with many electronics that need a battery that has good status charge and full-voltage.

The vehicle battery does not need to be registered with vehicle ECM as you have asked."


My Question

I have been reading about the Evoque and get different answers from a software update to drive it and the warning will go away.

Drove the Evoque for an hour let it idle checked charging and it is at a constant 13.99 volts turned the car off and checked the battery voltage it was at 13.2 volts. I think that the alternator and battery are fine but why is the battery light still on?

Some of these vehicles have a circuit reading the system voltage through a separate circuit to the charging system. If, after repairing the charging system, the code remains, it is possible that the fusible harness has a blown fuse, possibly caused by the original fault. You might reference some of my previous posts on this harness. Ray

Replaced, to date, battery, fused link harness and BMS battery post. Only code was B11DB-87
"fault in the electrical circuit" dealer says.

Please refer to the previous post here, as I addressed a potential fix for this code. The fuse in this harness may have blown, causing this code to reset. Ray
