Corsa power loss - good (independent?) VX garage in Berks?

[status]

My daughter's 2007 Corsa 1.3 Diesel manual drops into some form of get-u-home lower power mode when overtaking on the motorway in 5th, with the engine light coming on momentarily and then going off.

Doing the brake+accelerator error code dump gives me two codes, 6342 + 6123, but I can find very little via Google to suggest what these are trying to tell me, and/or if they're related to the actual problem.

So I think it's garage time.

If anyone has had good experiences with VX garages in the Berks area, particularly doing fault work, I'd appreciate suggestions (via PM if you prefer not to post names direct).

Appreciate any suggestions you have to share

Have you had a look on the corsaD-uk website? someone there might have an answer to why limp mode is happening.
