Grandland X exhaust leak lambda sensor

I had a similar issue with my Grandland X. Check engine light, rough running, and a weird smell. Have you checked for any obvious exhaust leaks? What about DEF fluid levels if yours is a diesel?

Mine is gasoline, so no DEF fluid. The exhaust leak seems to be coming from somewhere near the middle of the car, but it's hard to pinpoint exactly. Did you figure out what was causing your issues? Was it the lambda sensor?

Yes, it turned out to be a defective lambda sensor. The garage confirmed it with diagnostics. I suggest you take yours to a trusted workshop. They will be able to read the error codes and give you an accurate diagnosis.

Thanks a lot. I took it to the workshop, and you were right – it was a defective lambda sensor. Repair cost me 375€. Hopefully, this fixes the issue for good.
