Vehicle seemed to be in limp home mode.
There were strange gear change issues and on occasions the vehicle would not accelerate.

Vehicle came via another workshop who suspected a transmission issue.
This was an ongoing issue for about 6 months and had been getting worse.
One previous repair included replacement of the throttle body.

Able to confirm the odd drivability issues on initial evaluation and harsh gear changes.
Also noticed the lack of power over 40km/h, and the occasional engine cut out / stall.

Note:
At the end it turned out this vehicle had three separate issues, which were systematically repaired.
