Hi guys ive recenly bought a 2007 mk3 tdci cheap as needing a new engine.. im just wondering if it could be a simple fix now after reading mixed storys?

Basically it starts but sound like it firing on 3 and is really noisy at low revs and chucks out some white smoke. Theres no fault codes or any old ones stored no fpashing glowplug lght and Apparently it had pump injectors and turbo checked and all fine.

So my question is has anyone else had this kind of problem before I rip the engine to bits? If its engine damage Could it be a broken rocker assembly? Or more likly pistons or rods?

Thanks for reading guys look forward to you theory's

Dave
