hi friends am driving a skoda octavia 2008 model india. once it got drowned in water, her sliencer filled with water and engine turned off . as per the service felow advice i left the engine idle for an hour and the restarted it . for few days it was normal then i got the engine light glow while turning towards left side . i informed the service man near by showroow he scanned and said its egr problem and replaced it ... but again i find the same fault for which i again went to the service centre . this time they checked everthing and said all are fine but reason not found and now i get a small whistle sound along with engine sound and my car pick up drops once i reach 120 km/hour and runs like a snail with a black smoke on and off . again the scanning reveals egr problem . on the same day i got checked with egr is fine and they checked with the wireing too. kindly help me with this as i got exhausted trying many things.
