Gearbox issues??

Some garages (even Skoda ones) have unwittingly confused the drain plugs for the haldex and the diff, which aren't far apart.  You then end up with an emptied diff and a doubly filled haldex.  A short while later the diff overheats and fails through lack of oil

I wish that I didn't 😳

Not just garages that make the mistake although they have far less excuse with good visibility and access under a ramp.

I even had a second opinion from the eyes (twice as many as I have) of a Briskoda member on hand when I chose the wrong hole.
