vacuum pump
« on: October 03, 2019, 10:16:15 pm »
I have a 2015 mazda 6 auto-Nav 2.2 diesel.  98k miles.

I have had a "vehicle system malfunction" warning come up, and i have also had a set of disco lights for city brake, traction control, istop , and cruise control fails.  These re-set when the vehicle is switched off, but the system warning continues.  I have paid for the diagnosis, and am informed its a faulty vacuum pump generating too high pressure triggering the car into limp mode.....but Mazda didn't replace the part.  For the time being I am free of warning lights.

I believe this has been subject of safety recall on similar 6's.

has anyone any further information / advice?

Re: vacuum pump, MAP sensor carbon build up

The vacuum pump fault, but has since been discounted (removed checked, booked for replacement found working ok).  At the second visit carbon build up on MAP sensor was found and removed.

The faults codes and loss of power are generated all at once to protect the engine "limp mode", and in my case sparked off by (fairly moderate) revving....about 3000 revs is all it took last time.

have fingers crossed, and not revving the car as i can't lose it for a day in the garage for the next week or so.

can any body help with any other similar experiences?
