"I am receiving this error code - S84 Engine power is reduced. Has anyone else had this error or know what it means?"
"I took it to the dealership on Saturday morning and was there for 2 hours while they had a look. Apparently my car needed an update which was around 3GB and it took em ages to download because their internet is pants. They also took it for a drive and they told me that it may be an error on the ECM and that there is no actual performance loss in the engine. They also said that they are going to bring it up with their technical department to see if they know of an issue. I will keep updating if needs be I am hoping it is just a false positive on the cars part because its breaking in etc... other than that its ticking along nicely."
