Megane II 175 dCi Check Injection fault

[Sync0r]

The problem was present before the DPF removal and remap, so I don't think they have caused the issue. I'll take a look under the car sometime this week and see if all connections are good.

It's a good point. Given the location and temperatures... In fact, trace the whole circuit to the ECU.

I would really just first check all the connections are OK in that area.

freelanderuk, is this the same way your DPF is removed (hardwer wise)

[freelanderuk]

They cut open my dpf removed the insides and rewelded it all ,then red the ecu and applied a custom remap to remove the dpf regen settings from the ecu

sorry for late reply on trouble code, this is what I got out of auto data :
Throttle actuator control (TAC) motor - range/performance problem
couse: wiring, TAC motor

when you removed the dpf, and put the decat pipe on instead. hopefully they did't keep the dpf as they are worth 200 in scrap!

I think you mean the catalytic convertor is worth some money not the dpf

get to RN dealer and get a proper diagnosis.. a mechanic suggesting simply swapping parts is of no use!
