Further Contamination
Since the initial problem in 2007, many people have reported problems with their cars after filling up with petrol and diesel at Tesco filling stations. These problems normally caused the engine management light to come on, and ranged from problems with the fuel system to damaged oxygen lambda sensors. They may have been caused by silicon or even water found in the underground fuel storage tanks.
The latest incident to occur was in March 2012, at a Tesco filling station in Huntingdon. The contaminated diesel caused a £500 damage bill to Andy Ibbotson's Saab 9-3.
