Still not getting very far with this problem, but someone who knows the same engine from a Vauxhall Frontera has suggested a gearbox fauly or low fluid level. I'm tempted to believe him as the TOD check light has now started coming on intermittently when the car is idling. It goes off if you rev it.

I tried checking the fluid level, but its kind of hard to read - there is no definative level, more a smear of fluid all up the dipstick.

Does any one have any experience of gearbox problems? What actually causes the TOD Check light to come on? Is there a set list of possibilites?

Could gearbox/fluid level problems affect the engine revs? I dunno if the gearbox ecu has a direct effect on the engine or not?

Cheers
