EML keeps coming back on ! Help please !

[A4 TC]

Hi guys need help badly !
Had the EML come on and reset on numerous occasions and had it scanned and the code come up with P1128 and other codes saying running lean , quick search on this forum and suggestions are change the maf and airflow sensors !
These have been changed today leaks have been checked for ! And driving home today the EML has come back on again ! Starting to really p*ss me off now cause its been back to the garage numerous times .


So guys , is there anything else I need to check or change to get it back to normal again ?
Cheers A4 TC

After you changed those things was the car rescanned for fault codes? And had they gone?

The car was rescanned and the p1128 fault code cleared ! The car drives fine for a little while , then I can tell the engine management light is going to come back on cause the car struggles for power and feels very flat ! and another visit to get it scanned again , the same problem of running lean ! Getting sick and tired of back and forth to garage !
P.s it's a 1.8t Quattro sline by the way !

It may be worth pressure testing the boost system and checking all the vac lines my mate had similar and turned out to be a broken nipple on the inlet manifold that the fuel pressure regulator connected to

Needs logs done ideally. But a lambda sensor can go bad and cause it without a code being thrown...

Finally ! Hope this sorts it ! A split has been found on the air intake pipe right where the jubilee clip is , so made it harder to find !

Thank you guys for the input given !
