i,ve been doing some resaerch on line , sensor might not need replaceing , have found a product which cleans cat and sensors,its called CATACLEAN, read some very good reports on this , so i,m having a tenners worth and see what happens ,also going to buy code reader to reset light .
hi all had car 3 weeks same problem , dealer reset light but it re-appeared , surprise,surprise my 3 month warrenty does not cover this, so is it something i can buy and replace myself ,very limited know how but can follow a book if you know what i mean,also he said sometimes they just need a clean, any ideas on doing this cheers all
