Hi.
Nice to see a 'GENUINE' mechanic being able to help.
I've unfortunately got the same fault on my mk1.
I looked on Youtube, and there's a good video showing how to replace the solenoid.
But doesn't show how to check or top up fluid.
So if the garage you used sorted with just a fluid change, that sounds like a plan.

This is my 5th mk1 Scenic,
Did have a mk2 (didn't like it).

1.6 16v Privilage Auto.

hi guys I've got a 2006 1.6 16v auto and after having it for a week or two it started coming up on the dash saying electrical fault and check gearbox and once you turn engine off and back on car was fine well I done alot of research on this and also had codes read by 3 different garages and each one has told me the same all saying that it's the electrovalve solenoid in the gearbox valve block and it's about a £500 fix. well I had it in at another garage and the guy told me it's the same problem but only he wasn't just after money like the rest he said that the majority of the time it just needs the filter and the automatic transmission fluid changed and an transmission fluid enhancer added into to it. well I got him to do it for me it cost me £90 and I haven't had a problem since. I really hope this could help other owners in future with the same problem. the enhancer that was used is called Lucas oil but you could also use lubeguard platinum and it specialises in unlocking solenoids and keeping your fluid at a lower temperature so it doesn't burn away
