Stop collecting takeaways in the car. ! !      >:D >:D >:D

On a more serious note.  What sort of smell ?   We need more info. You're not giving us much to go on.

It smells a bit like that smell you get when your car it ticking and you are close by the exhaust and the fumes are coming from the exhaust.

If it smells like exhaust fumes ( your signature shows you have a diesel so should smell like a diesel)) then i’d probably be checking the exhaust along its entire length. If it is exhaust gas i would expect a crack very close to engine / manifold area for it to be finding its way into the cabin air intake. Saying that I would also expect that if this was the problem it would diminish with increasing speed as external airflow should dissipate the exhaust gas more.

You could also have a crack in the heating loop but that would smell like antifreeze I guess (no idea what that smells like)

I’m no mechanic though so these are just my best guesses

The 1.6 d is known for leaks at the turbo. Amar on here had one, it was literally a case of rev it with bonnet up its usually visible.

However if just mean you can smell heat, it could just be the element burning off crap if it hasn't been used at high heat for a while. But you'd expect that to clear quickly and stop smelling.

Folks there is no loss of power in the car and as i said it only smells when heater or air con is on, had it with mechanic today he ruled out anything major he will get a proper look after the holidays as he was very busy.

I had this on my wagon with a leaking injector. Get it fixed ASAP if it is a leaking injector

Hmm , maybe you have small leak at one of the coolant hoses , i had fumes in cabin again after sorting out exhaust clamp , turned out to be loosen hose clip  at the thermostat end  ;) . Also check EGR for leaks at the back of the engine .

PS. I'm done with diesels , stupid thing is so dirty , leak there , leak here  >:( , oh did I not mention that I can't sort out cold start rough idle for 4 years
