Hi all I have a problem with car leaking fumes into car aswell as a toxic smell on outside of car had smoke test done to no avail smells coming from engine bay back of engine maybe any ideas thnxs

Which engine? What fuel?

My guess is that exhaust fumes are escaping then being drawn into the heater inlet. Is the EGR blocked? Is there a hole in the exhaust/silencer system?

PS. Exhaust fumes contain deadly carbon monoxide, a gas that has no odour. If you need to drive the car before fixing the problem ensure you have at least one window fully open.
