I’ve cleaned the EGR, manifold and intercooler, and replaced the camshaft. However, I’m still experiencing oil leakage near the turbo and the air hoses, and I’m getting a yellow triangle warning along with a ‘vehicle system malfunction’ alert.

 

Maybe tell us the model/year and mileage of your car? You said turbo. Is it a gasoline or diesel motor?

Has it been scanned for for DTC's ( fault codes )?

 

During the diagnostic scan, an error appeared related to the front radar and front camera. The workshop owner told me that these faults can show up because the battery was disconnected for three days while he was cleaning the intake manifold and the EGR valve.

The errors were cleared, but a yellow triangle warning appeared again. According to the diagnostic tool, the cause was a stuck VVT sensor — it was always showing as “open”.

Regarding the oil leak, he told me it is coming from the turbo itself, based on the amount of oil and the exact location of the leak.

lol.. it would be better to follow a factory service manual or a professional service website like ALLData . Most YouTube videos from untrained people to follow end in disaster with those following them. In other words use them at your own risk.
