  expensive". I have taken the amplifier off the car and checked the resistances across the four terminals - and these range from 10 ohms to 120 ohms, i.e. there is no open circuit or shorted circuit. I have spoken to a friend who suggests it could be the ECU or the distributor itself
• Dishonest John's Guide - all true 7 Oct 2001 (Forum)
  system fault, using a fault code reader that I built for 50 pence from instructions on the Internet. Problem was a faulty knock sensor (£60), but you can bet that if I had taken it to a garage, I would have ended up paying £600 plus for a new ECU.

  it to be as reliable as possible and given its a BMW any jobs are not necessarily going to be cheap. I am a bit of a numbers geek and use the bimmertool app coupled with a bluetooth v-link in the ODB2 port so can see everything that the ECU sees. Having had the EGR function removed from the vehicle, the amount

All to no avail. Bearing in mind that the car had new oil less than six months ago
