Hi Fellow Fanatics
Apologies if this issue has been raised in another thread however I have tried to search before posting and cant find anything specific.
I apologize in advance for the long post however I'm sure if someones shares the same issue they will appreciate the info and perhaps benfit form your knowledge
First off I am based in Malawi and we don't have an official BMW dealership or Service Center here (yeah i know ...why did i buy a BMW then !) , but Ive always owned a BMW since the E36
I'm not sure how many of others here are facing an issue with super knocking , hesitation , preignition ... I have never faced it before however I have a 2013 BMW F30 320i with AC Schnitzer performance upgrade
where I live the best fuel we can get is 93 octane , i have been advised regards using octane boosters such as NF Ultra etc and I have looked at all options
This morning I have received the below mail from BMW after months of fighting with em complaining about my issue ... first off i need to source better fuel ...i am happy to bring on my own fuel from RSA its not an issue as I am in the transport business and have trucks running on the route daily ...is there anywhere i can get 98 Octane fuel in JHB ?

With the superknocking, we need a fault printout to show the cause. There is a program established by BMW SA for superknocking for the N14 MINI engines and that procedure is very complicated, But is not for BMW. We do not have a lot of superknocking issues on BMW’s , If I don’t work on the car myself it’s going to be very difficult.
Ismail, Please follow these few basic tests and procedures before replacing parts. (It could become very costly if this is not followed correctly).
1. Run a system test on a ISIS protocol program to establish the fault cause (Superknocking is not a fault, it’s a symptom. (THIS MUST BE MADE VERY CLEAR TO THE PERSON WORKING ON THE VEHICLE.). Replacing parts for superknocking will cause more damage, and will be extremely costly with no results.
2. These faults that you read out on point 1 should be stored more than once for accurate diagnosis.
3. Start by doing complete and proper fuel analyses as 90% of superknocking issues are caused by fuel related problems. (Drain the fuel out of the tank and ensure a high grade fuel of at least 95 octane is filled in the vehicle. (This is the most important step if not done correctly the process will fail.)
4. Inspect the engine for any loose add on components everything must be secured correctly. (This will be things like alternator, aircon compressor ens.)
5. Inspect the spark plugs for any eroded electrodes or composites if this is OK do a compression test. Please do a proper old school manual compression test with the fuel pump fuse removed. The spec is 10.5bar but if you are not sure please attaché the test to the mail and I can have a look.
6. Then you have to remove all the intake and boost pipes, intercooler and see if there is oil in, Please attach a photo if there is, so that I can advice you what to do as there is 2 different repairs for this step?
7. After all this clock’s out fine you need to fill the fuel tank with fuel as in point 3 (minimum of 42L) then add the fuel additive from BMW, Part Number=83192183738, clear the fault memories and drive the vehicle until this fuel additive has worked through the complete fuel system. This will take approximately two tanks of fuel. (This will only take effect after the second tank as the first one will still be cleaning so DO Not add the additive on the second tank) as explained in point 1 you have to see how many times the superknocking is stored in 1000Km’s as certain road and driver conditions can also cause this. If the superknocking is less after the fuel additive process has been done, that will prove that this is fuel related. If this is the case I will let you know how to maintain the vehicle for this as you cannot drive permanently on the additive as this could cause premature wear of the fuel system.
This is very strong stuff so be careful not to inhale the vapors and dispose of it correctly as it is harmful to the environment.
Good luck with this and make sure the person working on the vehicle is a well trusted person.
