    Hey drivers & diesel mechanics,
    Got a 2016 T660 with 2015 MX13 & these two codes showed up P1086 & P00BA. Now I know it’s fuel pressure related. As per service manual when those two codes come up it says to refer to “Fuel injector nozzle leakage” on Rápido.

    Well I have no clue what rápido is or have access to. I think it’s some kind of software? Who knows, but I was wondering if anyone knows about this. Thanks in advance.

    If you just changed your fuel filter and it came up. You need to bleed the air out. There is a small brass fitting with a nipple on it just to the right of the fuel filter module on the motor. Loosen the fitting and pump the primer until a steady stream of diesel is flowing (not foamy) and the hand pump gets very tight. Close the bleeder valve and pump it up some more. Then crank it with the pedal on the floor until she fires. Try to hold it at 1500 until it’s finished popping and spitting then let it idle for 1 min
