Sorry to resurrect an old thread but I am having the same issue with my D4, feels like a flat spot around 1500-2000 rpm, is it possible to clean it in situ? I have stuffed a brake cable down there and it does go a fair way in but is it safe to spray something down the pipe and then try the cable again? is there anything at the bottom of the pipe that might be damaged from spraying cleaner in there? |

The inner brake cable I used was about one foot in length whilst spraying cleaner and working the cable at the same time it eventually cleared after about 30 mins but remember this was off the car. The EMAP sensor itself is some form of piezoelectric sensor so gently clean away any carbon with spray cleaner to reveal the tip within the recess. Use gloves and eye protection!

Sensor
Thanks both for your advice, much appreciated.
I actually had the engine carbon cleaned with hydrogen and it so much smoother and quieter but still has this hesitation, he also checked that the EGR was moving freely before he did the clean and it was fine and also a diagnostic check revealed only 8g of soot in the DPF so I'm confident its this EMAP pipe |

morning All
i have the same problem with my 2014 model 181 xc60 with the twin turbo, i had a look over the weekend and i manged to remove all but the heat shield to gain access from underneath, but how on earth do you get the shield out the way as its behind the oil return pipe for the right turbo or is it a case of bending out the way, information greatly received ta |

I'm fairly sure you can loosen one of the nuts holding it and bend the shield out the way...
I've given up on mine now, the pipe is clear as I can shove a bike brake cable all the way down and I can hear air coming out of it when the sensor is removed so i'm just living with it now.. |
