Default Jb4 on 340i B58 - 07-14-2020, 12:47 PM

Good evening. I am a current user on the forum, but could
not reset password . Emailed admin etc. Apologies had to create new profile as I need help.
Been using the Jb4 on my 335i and 235i, now on my 340i. 235 and 340 have Bluetooth connector.
340i ran on firmware v 14 , boosted well and strong. Got upto 1.3 bar plus boost.
Then national lockdown. Hardly drove the car. Then got back to it and boast dropped off very badly. Then upgraded firmware to V15. Got the boost up a bit, but I keep getting code.I use 95 octane on Map 4. I am assuming fuel quality is poor due to Covid , and reduced production in our country.
Always code 101F02, 101F01, 104302,108B07
Can anyone help please.
