hello, can you confirm that this heater is the very latest generation S3 D2L? It's a good price, I need the latest S3 because spend alot of time over 10000 ft, that's over 3000 mtrs guys. Thanks for any help

Hi, yes this is the latest S3 D2L, we're currently on a promotion price, matching our own web price for the outgoing S2 D2L, so it's quite a deal currently - more heater for the same money. This Eberspacher Airtronic S3 heater auto-compensates for altitude up to up to 4000m (13123ft)
