Smoke After Tune

Hi guys, own a 56 1 series 120d with 72 on the clock.

Had her tuned for performance and mpg. Currently for 202 bhp and 284lb/ft.

Since the tune I noticed she smokes more, under a little acceleration I see faint dusty smoke n harsh acceleration thick black smoke.... Once booted a few times she smoke will fade but will come back after normal driving.

Any thoughts or is this the norm with a tuned diesel?

Cheers guys

      105C thermostat replacement

      You are absolutely right. The strange thing is that when I put the chassis number on the realoem it shows that the temp sensor is not applicable on my vehicle. I will physically check for a sensor. In the meantime, do you think that the removal of the MAP activated thermostat will effect the temp gauge on the dial instrument item 6? I am tempted to add a dummy resistor , 11.5ohms - 13watts , to simulate the MAP thermostat. Your thoughts?

      SLIPPING CLUTCH

      Morning Andrew I normally disconnect the Neg lead only, some folks disconnect both a few even say disconnect both and touch them together. Goes without saying both sensor plugs need to be checked and a squirt of contact cleaner applied never hurts 😅 Dave

      SLIPPING CLUTCH

      Hi Dave, I fitted one of the sensors on the rear but it has made no effect as the light is still there, I will fit the other sensor tomorrow and see how it goes then. You mention the disconnect the battery, is there any pattern to this ? is it both leads or just the negative lead? cheers Paneuro.

      105C thermostat replacement

      Not sure what engine your running but there should be a Temp sensor in the Hose from the Rad to the water pump then there should be a Temp sensor in the housing for the Thermostat Both are shown in realoem for the 3.5 V8 I thought the V8 was the only one with dual use sensor on the Thermostat housing but stand to be corrected Dave
