Can anyone offer some advice please I would really appreciate any ideas. I have a 2013 model.

Yesterday I filled my qashqai with the correct diesel drove 40miles no issues. Stopped for five mins to get a coffee and when I turned the engine back on there was a really awful egg smell, five minutes later my exhaust was blowing out thick black smoke. I pulled over and called recovery to tow my car home. Topped up the oil and coolant this morning and drove it down the road and the black smoke started again.

Any ideas on what it is would be amazing!

The egg smell is commonly sulphur. Days of stink bombs.

What I remember of that and cars was poor catalytic converters. Points to exhaust system problem I think. An expert on it should turn up soon?

Katie, firstly welcome to the Forum. I am no Specialist for Diesels and it fact never had one. Please take a look at this attachment which might help you or give some ideas as it mentions both the “Black Smoke & Smelly Eggs” - Dave 😉

Looks like no "expert" turned up.

If this regularly happens (too often/nuisance) its best to goto a garage. There is a mechanism that the car engine management initiates periodically to clean the exhaust system out. Thats called DPF regeneration.

On the other hand you may have a fuel control problem. Black smoke is a distinct symptom and certainly some smells come with that.

intersting reading DaveBerlin, thank you for that insight because my first thought was contaminated fuel when filling up
