Help.....
i I have the same problem for the last month with SCR Malfunction after running low of Adblu when the car was due for 50000 mile service. So had the full service and Mazda dealer topped it up. It always takes at least two days or 100 miles for the adblu tank to show 4 circles or full again. A few days later.... SCR Malfunction is back on. I took it into Mazda dealer who reset the system and it disappered this time for 250 miles. Then its back again showing 520 miles.. Its in the first limp mode I can still do 80mph but by the time it reaches 250 miles left its slowed to 60mph max. Then suddenly after a car wash it resets and is totally fine showing 4 circles full Tank. A few days later the problem re-emerges and is now a permanent intermmittant fault.
Visiting my dealer for the 3rd time today. They took a look reset the system. Then came the bombshell. We think you need a new SCR control unit. We'll speak to Mazda HQ. But prepare yourself the cost for a replacement unit is 968!!!!! HOly s*** this car is only 4 years old WHAT GIVES?? Any advice most appreciated.
Not prepared to cough up as Mazda don't seem to have a clue!!
