Polo 9N AWY 'check engine' light on

Just cut it and re solder less the damaged section if you really want to be tight

Akagi · 26 Oct 2014 at 15:22

Will give it a go perhaps.

Have driven another 50 miles or so since the light came on and everything still seems absolutely fine.

What cheap OBD reader would you recommend? I would just get a VAGCOM cable, but I don't actually have a laptop.

And they're stupidly expensive. Check clubpolo or any VAG group for guys in your area with VCDS or w/e it is.

They are like £5?

My bad must be thinking of something else...

Have ordered a reader at the recommendation of someone from the Polo forums. It should be here tomorrow.

£16.99 including upgraded delivery.

Really? What is the point in *not* using better quality fuel when it is only 3P more per litre? :confused:

It surely has to be marginally better for the fuel delivery & injection components, it costs about the same amount per mile because I get a few more miles out of a tank*, and to me, the engine feels slightly more plucky with less flat spots.

*I tested something like 8 tanks of regular 95 and 8 tanks of Momentum 99 doing the same runs to and from the same places and I got a consistant 2 - 3 MPG average advantage over 95 when using 99.

It makes no difference to cars not tuned to use it, I've been using supermarket fuel for over 20,000 miles with no problem. I did 1 tank of Super out of curiosity and the MPG was the same and the car drove the same. Running it on a 3cyl 1.2 6 valve engine is just utterly hilarious.

I have all the figures noted down somewhere, will look for them when I get home if you want.

I was surprised by it as well. It might be something to do with the weird low power triple cylinder short-stroke engine in the Polo? Something knock sensor related? I don't know...

Your car doesnt care and can't take advantage of it - any difference was down to you, not down to the fuel.

Akagi · 28 Oct 2014 at 15:28

Seems a little odd that each tank was consistently better... I don't know what exactly I would subconsciously change about my driving style if I know I have better fuel in the tank?

Janesy B · 28 Oct 2014 at 15:38

Depends how many hedgerows you ended up in I guess?

THAT WAS ONE TIME JANESY B! ONE TIME!

Unfortunately it did have a tree in it.

It'll never be forgotten, I have the picture saved on my phone from the time you sent me it after you'd done it

Your car has illuminated a light telling you that there is some sort of engine fault. You don't yet know what this fault is, so your idea is just to... keep driving the car? Really?

It's not 'better quality' per se, it's just a different specification, a specification that is of no use to your engine.

it costs about the same amount per mile because I get a few more miles out of a tank*, and to me, the engine feels slightly more plucky with less flat spots.

All placebo. It makes no difference.
