159 2.4 JTD Ti Q Tronic

During a recent warranty visit, my car received a software upgrade. Since then, the car has developed a cough between 1800 and 2000 RPM. If I drive in sport mode, I appear to miss this cough, but in normal mode, its a pain. Has anyone else experienced this?

Mine started doing this the other day, it does it in 6th at 1750rpm, and sport mode keeps the RPMs higher so it doesn't happen. (feels like a short shudder / hesitation right?)

First I cleaned the injectors and that made the car quicker, smoother and the gearbox behaved a lot better. It also reduced how frequently this happened, but its still there. I have just cleaned the intake manifold and butterfly valve as it was a bit caked up but have not yet done a long run in her so no idea if this has sorted the issue or if I need to look elsewhere.

will let you know if it has cured it.
