Hi all

Hope anyone can shed some light for me. I am busy searching for a cutting out and not starting problem on a friends 2000 V5 Auto Bora.

The basic symptoms are;

  1. A slight misfire when running - Suspect the Coil/Module (It is a non genuine part)seems to not be firing on all cylinders all the time - mainly not cylinder 1 but varies from time to time?
  2. She runs o.k but sluggish
  3. Sometimes will run beautifully for any period of time without cutting out and then the next trip cuts out whit in minutes.
  4. Also noticed that after switching it off and then starting sometimes will fire right up and then other times not.


Things we have already checked:


  • When she wont start there is fuel but no spark at all
  • Replaced crank position sensor (did not remedy the defect)
  • Found several vacuum hoses collapsed/broken/ split. busy replacing them all.
  • Checked contacts for corrosion and general condition - (Cant really say any of them is corroded or faulty)


What next, Temp sensor - Cam sensor - ECU?

Any help will be appreciated.

O Yes - No fault codes is generated that indicates sensor, ECU or CAM faults.

Thanks.
