I need an SOS battery

[Spokegg]

Anyone know where I can source an sos battery for T6.1 part number 3G0915089. I've looked around and there is a variety of pricing, including refurbished(?). I'd like to fit it myself to avoid getting fleeced. Also, any pics or vids on how to get behind the binnacle would be great. Thanks

Have you seen the posts on here regarding a fix that means you might not need to replace this battery?

Or call my VAG tech Andy TT-Spares

A really clever guy who found a battery that works just the same. I know because he did mine some months ago.

Once again I swear I get nothing in return for mentioning them. But good people deserve the business in my opinion.

Have you read the codes ? You are making an expensive assumption that the eCall battery has failed.

There are several exhaustive threads on this forum, it's likely that you simply need to reset the eCall battery health in the Telematics module.

Yep, this is what I have done and fault has cleared. OBD11 has now paid for itself!
