Title: Is this a common issue
Post by: vwgolfv5 on 13 July 2013, 09:53

I have noticed when I put standard 95 ron fuel in the car, you can almost guarantee the CEL will come on. When I plug my reader in it is always the same error, no signal or wrong signal at the 02 sensor.

When I put V Power or equivalent in, it never happens and runs just fine.

Is this common ?
Can it be mapped out ?

And while I am at it, what other mapping options do I have with this car ?

I assume this is not a common problem ?

Same question though, is it possible to map it out ?

On a v5 you will be unlucky to see more than 10bhp with a map the only thing that will really improve is throttle response... As for your issue not sure possible the 02 sensor is just faulty... on a cheeky note just use vpower  :laugh:

Thanks Damien.

The trouble is, I'm trying to get away from the mental V Power prices, thats why I finally got rid of my import TT Subaru.

As for the map, I'm not bothered about power gains, it will never be as good as the Scooby  :cry:
But better throttle response sounds good.

Thank god I bought a VAG reader, saving me a fortune on garage prices already and I can clear the code and get rid of the annoying light on the dash   :rolleyes:

I would say the O2 sensor is faulty
