Smoking from where?  The tailpipe or the engine compartment?  If it was the
tailpipe, perhaps your timing belt or tensioner wore out and the belt jumped
on the gears.  That would make it run poorly if at all.

If it was from the engine compartment, it is likely that something was
binding up and preventing the belt from turning, melting it from the
friction.  Check that the camshaft and crankshaft are turning with no unusual
resistance, along with any associated timing pulleys.

Hopefully you did not overheat the motor because you could be in for some
real fun if that was the case.

the car  should be taken off the road it's going to nickel and dime you now

TSi?  You will also have bent valves if the belt slipped a couple of
teeth or broke.
