Was just wondering if anyone has had any issues with Supermarket fuel killing lambda sensors?

Basically my EML light came on yesterday and I left the car at the garage today and I've just rung them and they said it needed a new lambda sensor, possibly caused by supermarket fuel, now the nearest petrol station to me is Tescos so I've been using their 99 stuff as I only use super unleaded in it.

I'll try avoiding the supermarket fuel if this is the case, was just wondering if anyone else has had this??

i think its a myth. i really can't see that tobesco's have there own special watered down fuel. i say your nearest posh brand station has the very same supplier.

Thats what I thought, seemed odd, I've only had the car a couple of weeks and only had 2 tanks of Tesco's 99, so can't see that I've done anything to kill the lambda sensor lol.

I've been running on tesco 99 for ages, and nothing has gone wrong.

What mileage does the car have?

Its on 108k, I was due to get the car back tonight, but they've fitted a new wheel bearing to it but the ball joint is spining, so won't get it back till tomorrow now :(

Been running Tesco 99 (now "Momentum") for 2 1/2 years with no problems at all. Only time I had an issue was with BPs old 99, which even with 2 tanks ran like a tortoise with 2 legs..

I'm on a 110k and car is running sweet. Wouldn;t use anything else TBH...

Carry on using Momentum - nothing to worry about !

I use Weston Favell as I'm over in Ecton Brook

Yes I have had the same problem with fuel from my local Morrisons. Tesco was find a couple of years age for adding to much silicone to the fuel

Isn't morrisons petrol 95 RON only?

Yea Morrisons is only 95 as they don't do super, I recon the previous owner only used normal unleaded which is why it decided to go.

FYI

A lambda probe went on mine at about 60k.

They are just like any other part, as in they can go at any time.

Well I had the car back less than 24 hours and the engine light has come back on :(

Does the VRS have one or two lambda's?? think I need to see someone who has VAGCOM and see whats coming up and then go and moan at the garage again lol, had the car 3 weeks and they've had it in twice for stuff so far lol.

Interestingly on the Fabia I forum, twenty replies to using Supermarket fuel.

Iirc.the octy has a.pre and post cat sensor on the downpipe, the post cat being the most expensive.

Had to change this on my first vrs. Hope this helps.
