Evening all not posted for a while due to work commitments just need some help please.Recently took my car for a M.O.T passed with flying colours next day later fancied a spirited sunday drive so turned boost up and off I went, when stopped at lights noticed smoke coming from engine bay popped bonnet and smoke was indeed coming from the engine bay with (burning or melting smell from infront of turbo somewhere) but not blue smoke clear if that makes sense, so turned boost down and limped home.When I arrived home no smoke and I have noticed this only happens when boost is turned up car still hits full boost and pulls as normal also no blue smoke on start up or at any other point just need advice on what could be wrong as funds are a bit tight until pay day PLEASE HELP me on what could be wrong.

 

ANYONE

 

Sounds like oil burning off somewhere. More boost = more pressure so possibly leak only showing itself then.
Check round bottom of rocker gasket and around turbo and oil pipes.

 

It could be anti-freeze leaking onto the manifold. After I had a service once they had spilled some and had loads of smoke coming out, had to stop and check a couple of times. By the time I got home it had stopped. It just needed time to burn away. May not be problem but if it was leaking constantly at high boost that could be whats up.

leaky pipe to turbo only coming out under pressure does it smell sweet and have you lost any coolant
