Hello, actually wanted to order me a Heico XC60 D3 AWD. However, the dealer (and another car dealer) advised me not to do so, because with a software update for the engine (of Volvo) the data of the Heico chip are deleted (or no longer fit) and this should be reprogrammed. I then ordered (according to these statements) the D5 AWD. Has someone experience with Heico and updates for engine etc. ? VG, Pelzebubub
