I have a 2014 Mazda 6 2.2 Sport Diesel with 150BHP engine. No problems to 55,000 miles, although the fuel consumption seemed to be getting worse.
Then on a long run the the red warning triangle came on,indicated, an SCBS inspection required. A few miles later the cruise control turned itself off, heater stopped blowing hot air, Gear indicator light turned off, and further warnings showed for DPF and engine. The car ran ok, but lower power.
I took it to the local Mazda garage. They diagnosed a turbo problem and replaced the 'small' turbo (it comes in 2 parts?) and removed carbon deposits. They said this was a common problem and the fix was sound.
Driving home from the garage, the car was jerky. Before I had done 5 miles the SCBS warmong light came on again, and after 20 miles the crusie contol turned off and the array of warnings lights came back on. The jerkyness stopped at this point which I take to mean the turbo had given up. I'm intending to return it to the same garage.
Has anybody else experienced these symtoms? Any advice?
