Hello. I have got Tucson 2016 1.7 CRDI. When braking (e.g. when approaching a junction or when approaching traffic lights) and pressing the clutch (when I almost stop), the revs increasing (200 rpm, sometimes even more, even up to 700, sometimes they do not increase), depends on how fast I am driving. Has anyone had this a problem before? Or is it normal?

 

A part time vacuum leak could raise the RPM when the load is removed from the system.. Don't know if this is the problem here.

 

Did you get this sorted and what was the problem? Its happening to my car as well

 

I’ve got a 2017 Tucson that does the same thing, and the faster I was going before coming to a stop, the higher the RPMS go. Did you happen to find any answers?

 

Nope no reply from first poster. Im still getting the problem

 

If you don't come to a complete stop and say at 25 MPH and you depress the clutch, does it do the same thing?

If so, extra air might be getting into the engine and the system thinks you are opening the throttle , and thereby increases fuel as a response.
