UPDATE
2 o2 sensors have been replaced at a cost of £375 plus Tesco told me to rent a car while mine was being repaired as it took a week to get the sensors in stock. I was given a 1.8 SRI astra which totaled £242 so total bill was £617

You only just got around to getting yours sorted out?
Mine went in a couple of weeks ago.
The O2 sensor had managed to survive the onslaught of Tesco petrol and was simply giving false readings rather than being completely dead.
They removed the sensor and fully cleaned it.
They then totally drained the engine and stuck 10L of Super Unleaded in - total cost £235inc
If I'd known that Tesco were going to admit fault I would have taken a loan car for the week leading up to my booking at the local dealership.
On the day that Tesco took out the full-page adds I called them and then sent them all of my receipts.
Five days later I got a cheque from them for £280 - The £235 repair bill and the £45 worth of contaminated petrol I put in which caused all this hassle in the first place.
Driving home after all the work was done on the car was like night & day - after a week of stuttering, loss of power etc the smooth ride home was lovely.
It only took Tesco five days to deal with my claim as well, however I did (by total luck) have my receipt which showed when and where I'd bought the fuel from.
To this day I don't know why I kept that one (it was paid for by cash too - so I wouldn't even have been able to get a bank statement to prove purchase) but for some reason I did.
