75-Telematics -- Status: Malfunction 0010

[chris ratay]

Got this Telematics error the other day. Cleared it first with Carista and then with VCDS, but it keeps coming back. On the dash.

Vehicle says everything is fine and there are no warning lights, but there's a periodic chime that's low and pings 3x.

Traveling in South America. Any specific instructions would be appreciated.

Most telematics modules have a built in backup battery.
In your case the module itself reports a fault, claiming that this battery has a 0 mAh capacity left.
Typically these batteries are 7.3V and capacity of 1390mAh.
I would try to replace it.

The telematics boxes have been slightly problematic on the T6.1 with lots of examples of units showing errors, i think earlier vans got a software update but have heard of quite a few getting replacement modules but never seen one myself so not sure what error codes are typical for these in comparison to what you have ?

Thanks. Any idea where the battery is? I'm in Argentina and they don't sell these vehicles here.

My Google searches on my phone have also been fruitless, so any other hints/specifics would be greatly appreciated.

Just cleared these a few minutes ago

Not sure I would worry about it, if your in a country where the box has nothing to communicate too then seems little point getting overly concerned

The battery sits under a dedicated cover on the Telematics unit, which is located behind the Instrument Cluster.

The chime every 1-4 minutes was super annoying. It seems to have stopped, but not sure why, or if it will remain quiet or...

My MAN TGE (VW Crafter with different badges) reports that the Telematics battery is low, my dealer says that it is not replaceable and the whole unit will need changing. Not my problem as the vehicle has an extended warranty!

On T6.1 the battery status is available via VCDS advanced measurement values - below snippets from two different vans.



Per wiring diagram the unit 75-Telematics (J949) connects to KL30a wiring harness - thus permanent 12V there.

@mmi thanks for the update and info.

I have just been and looked at the status of mine in the TGE after yesterday's journey. All good now!

Thanks. The van is parked in Buenos Aires for the next 7 months. When I return I'll take it to Patagonia.

Is this something that can be ignored, or will it cause problems. If problematic, is it a simple or difficult fix?

I have a local mechanic who works on new Amarok (Euro 2)

Your main concern if leaving the van parked for that length of time will be the engine battery charged. I guess you will either disconnect that or have some means of trickle charging that battery whilst it's parked.
I believe that the telematics module is of little use in your country due to its lack of ability to communicate so the battery in that discharging is of no consequence. i.e. don't worry about it.
