Post Software Update

Hi guys,

Quick update.

I took the car back to the mechanic who reassured me that the fluid used was a high quality OEM and hasn't given him any issues in other 1 series autos. He comes highly recommended so I don't think he would stuff around when it comes to this.

He also checked the injectors but was unable to find any faults. I still find that the engine is a little rough idle on a cold start.

There was a fuel pump ECU upgrade along with a few others so he flashed the firmware to the latest version.

I drove the car to work for the first time this morning and I would say the shifting was worse than ever, particularly in 1st > 2nd. Its no longer slow/lagging but much more violent and noticeably louder. Should I be concerned by this? Has anyone else experienced this after a firmware upgrade?

Thanks & Regards,
Jack
