Xhorse MQB RH850/V850 Adapter has been released now. With it, there’s no need to cut wire or lift pin to read MQB48/MQB49/5C dashboards. It can support to read VW 4th Gen Johnson Control 34xx series, MQB-RH850(R7F) series and MQB 34xx series dashboards.
But it’s worth noting that the adapter can only work with Xhorse VVDI Key Tool Plus and need MQB NEC35XX License activated. Following, we’ll demonstrate how to use RH850/V850 adapter to read the 1401 dashboard as an example.
