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?

My problem was caused by dirty injectors/fuel system,I solved my issue by using injector cleaner, just get an injector cleaner with polyether amine (PEA) like Techron concetrate, Royal purple max atomizer etc,i use a bottle twice or three times a year and the problem has never returned, also make sure that the fuel filter is replaced every 2-3 years.
