Latitude exhaust leak and rough running

I have a Latitude as well, and those symptoms sound awfully familiar. I had a similar problem a while back. Have you checked your oxygen sensors? Mine went bad and caused all sorts of issues with the exhaust and engine running.

So, if I understand correctly, replacing the oxygen sensor fixed the exhaust leak and the engine malfunction?

Well, it wasn't a visible exhaust leak, more like a very strong smell and the engine running rough, plus the engine light. Replacing the oxygen sensor fixed all of that for me, but honestly, with a real exhaust leak I would suggest going to a workshop. It cost me around 375€ to get the sensor replaced.

I appreciate the clarification and your advice. I'll take it to a trusted mechanic to get the lambda sensor replaced. Thank you!
