Dear clever people On page 143 of tsd 4737 it shows the knock sensors connected to the k motronic ECU, on page 196 of tsd 4737 it shows the knock sensors connected to the boost ECU. My car is '89 turbo R KCH27650. Any guidance would be appreciated! Cheers Mike |

Hi Michael, I'm not familiar with your model but when I looked up your VIN on the Bentley Heritage site it shows the knock sensor wiring goes to the boost ECU somewhere inside the front left wing behind the headlamp. |

Hi Mike, I looked it up on https:heritage.bentley.com and went to their parts catalogue, entered your VIN & looked under engine electrical where I found a diagram of the knock sensor location and associated parts. |
