This video I think clarafies that it carries over the new ecu mapping for a burbles on throttle let-off.

So, the difference between the ST280 and ST290 is only the ecu mapping?
Thanks Jarre. It's the 290 ST I'm particularly interested in. Anyone else with any insight? Thanks
Does the Leon have exhaust valves?
I wonder if it suffers the same setting glitch as the R then.
In the R if you have the engine running and you select R mode the exhaust valves open. If you then turn the car off, next time you start it, it will still be in R mode but the valves will be shut. You have to reselect R to open them again.
