  Q: How can incorrectly tightening a knock sensor fastener affect its performance on Volkswagen Golf R?

  A:

  Poorly fitting a knock sensor fasteners may interfere with the functionality of the knock sensor. In case the battery is disconnected, it will be necessary to re-learn several systems until they will start to work properly. To do so, with 1.4L and 2.0L non-turbocharged engines, lift the front of the automobile and place it firmly on jackstands, and then remove the under-vehicle splash cover and the drivebelt. In 1.4L engines, get the air conditioning compressor bolts out and fix the compressor to the side. Find and unscrew the knock sensor electrical connector, pull the bolt off and unscrew the knock sensor off the block. Installation is the opposite of removing, and the knock sensor bolt should be tightened up to the torque. In 1.8L and 2.0L turbocharged engines, initial steps are the same, namely, disconnection of negative battery terminal and emptying of the cooling system. Disassemble the intake manifold and water pump, disconnect hoses and electrical connector to the Engine Temperature Control Actuator and disassemble the actuator. Disassembling The old O-rings should be discarded and the new ones installed and then the knock sensor harness connector should be disconnected, the knock sensor bolt removed and the knock sensor removed. Installation is in reverse of uninstalling and the knock sensor bolt is tightened to specifications. In the case of engines with 2.5L, the two knock sensors can be found beneath the exhaust manifold, and their electrical wires must be disconnected, the fasteners of the heat shield removed, and the screw fixing the knock sensor must be removed. Installation When fitting a knock sensor, the sensor mounting screw should be firmly screwed to its torque, and otherwise the installation process is the opposite of the removal process.
