Just Fulled Up Now The Engine Management Light is On!

[hadz]

Hope you guys can help, as im sure you have all seen on the news at the mo in the south east there is big trouble with certain batchs of fuel. Anyway i have been puttin off filling up till the problem was sorted. I was forced to fill up today and decided to give the old girl a present and fill up with a tank of V-Power super unleaded from shell. All was fine to start , bout 10 mins down the road the engine management light came on. Im now worried it could be this s**t fuel that is going round!

any1 else has this problem? Or could it have been caused by using the super unleaded as i normally just use the basic cheaper unleaded stuff?

any help would be great!

cheers

was your car setup up to run on high octane such as 99ron or set up for low grade fuel such as 95ron? As far as im aware shell wasn't affected by the dodgey fuel, im in the south east too and iv filled up in a couple of shell garage no problem!

no point guessing

could be one of a million things and totally unrelated to the fuel

scan it and if its a dodgy lambda then it prob was

pdcupra - what do you mean was my car set up to use high octane fuel? it doesnt really matter if u used the normal stuff or the super unleaded does it? does it matter if u change between the 2?

No it does not matter if you switch from one to the other as we have an adapable ecu. Get it on vag com. Suspect its just coincidence!

V power, Optimax and the higher rated fuels not affected by it, only normal unleaded!

It does if your car has been re-mapped as they set the map up to what fuel you use.

i can tell when i use 95ron in mine, runs like a bag of spanners, thats why ive only done it once!

 

[pj1985]

Yes but as he didn't know what set up to run on it means I assumed he didn't have a map. Also as he had actually filled up with vpower it wouldn't b that setting off the engine management light. Putting 95 ron fuel in a car mapped to run 97 or higher on occasion/emergency won't actually do too much, you just won't get the performance and it wont run as well as it should.

 

[pdcupra]

but i was unaware if he'd done it the other way round, but looking back fuel probably isnt the problem! esp if he filled up with lovely v power!

 

[pj1985]

He said he'd filled up with vpower. Like I said its prob just a coincidence that its come on. I have the same prob with mine...fix one thing and another light pops up, switch needs looking at, sensor needs changing etc.

 

[pdcupra]

cupra-itis mate! they all have the disease!

Just get it looked at. All speculation now, its an Ibiza, the light could have come on for lookin at it the wrong way.

 

[pj1985]

Yep! I turned my back on my car this morning and it went for me! LOL! Vag com is the answer. Hope its only a small prob and easy fix for you!

 

[hadz]

cheers for all the help lads! got it booked it with the dealer on friday! fingers crossed it isnt going to cost me loads!

 

[gavthelad]

if its the fuel.....which i doubt, it wont cost you anything. unless you have to stump up the cash and claim it back?

 

[hadz]

Right my car is now all fixed! Took my car to the dealer yesterday and the fault was a O2 sensor , got it back and it ow seems a lot faster , the pick up is quicker and also its now boosting more than it did b4. Is it likely that my car had quite a few minor faults that didnt turn the engine management light on? Much more fun now tho!

so there you go
