1.4tsi Soft limp mode P30C0-000

[rockport]

Good day ,I own a 2011 1.4tsi 122 and keep getting the error below on my car,the error puts the car in soft limp and wont boost above 0.3 bar but does not cause an EML light,i tried fuel from different garages and even octane booster to rule out bad fuel as the cause of the issue,but the fault keeps coming back,any ideas of what the solution is?

Faulty knock sensor maybe. It cannot physically measure fuel quality but can base the assumption on that it is knocking even though it is fully retarded.
The other possibility is do a compression test. They are known to break ring landings and might might be picking up that as 'noise' on the knock sensor.

Solution:I dont like to leave threads hanging,so I will share,the car got worse and started hesitating between 1800-3000 rpm,ltft went up to 7.8-11 on most days.i changed coil packs and this made a slight difference at idle,the code came back after driving for a short while,the problem was eventually sorted by adding liqui moly injector cleaner to the tank,the code has not come back and the car has been driving well for 550km.will update if there are changes.
