HDi TDCi D 2.0 diesel throttle body cleaning

1. Open the hood and locate the throttle body. There are two types: with single and with double inlets.
2. Remove three torx screws from the throttle body.
3. Disconnect two sensors. MAP (manifold absolute pressure) and IAT2 (intake air temperature).
4. Disconnect vacuum line (or lines) from the intake flap (or flaps).
5. Remove the throttle body from the car.
6. Remove screws that hold together sensors and the throttle body.
7. Remove sensors. Be careful and don’t brake the o-ring on each sensor.
8. Clean the throttle body. Don’t use aggressive cleaning solutions. I’ve used petroleum ether. Notice that flaps should move freely.
9. Clean the IAT with petroleum ether. Do not touch the sensor directly, use soft brush.
10. Assemble throttle body and install it back in the car. While installing you can look inside intake manifold and check it for carbon deposits.
