Engine Management Light on but car running fine
« December 10, 2017, 07:06:45 »
When I bought the car from new there was a faulty emission sensor that meant the EMS warning light was on permanently. This was replaced under warranty and has been fine until this week when "Hello again" and the familiar orange warning light appeared on the dash.  The car is running smooth as anything (especially as it has just had a new warranty gearbox!). Should I rush to the nearest dealership or is this a regular feature of the i30 ?

Is there an easy way to find out WHY this light is on WITHOUT going to a dealership?

Comments appreciated  :D

You can buy an OBD reader and read out the codes yourself, then google the codes but since the car is still under warranty, you will need to visit the dealer anyway.

Rule of thumb is you can drive the car as long as it feels and sounds normal, but of course the light is on for a reason.

Please tell why you had the DCT box replaced, we haven't heard of issues with those..

Thanks for that I will get hold of this OBD reader ... I guess there are instructions on connecting it on the internet  :)

Regarding the DCT ... see my posts under "Auto gearbox judder in low gear and not changing down under load" posted in this forum

It plugs into a socket under the dash - drivers side.
You will find that you can read then clear the code ( light goes out). But note the code(s) before you do that. If light goes on again, you have a problem. Go to the dealer.

Well I ended up buying the U480 OBD2 reader and after working out that you have to have the door closed and engine running to overcome errors, I managed to get the error codes that are causing the engine light to be on "P2271 - O2 Sensor Signal Stuck Rich Bank 1 Sensor 2"

Waiting to hear from the dealer whether it's just a faulty sensor again but have been advised that the car is perfectly safe to drive

I had the same code on our previous Rav4. Took me ages to get the sensor out (it was virtually welded to the engine block).

Once out and replaced, I then got another code referring to sensor 1 :rolleyes:

You may find you're using more fuel than normal.

Not sure of your warranty conditions in England. It should be covered as a mechanical failure.

That O2 sensor is on the exhaust past the catalytic converter. It would be ok for the average handyman to replace. However, check that the lead to it is secure. May have been disturbed when they did the box replacement.

 :)  Found new dealer in Puget sur Argens and they confirmed diagnosis and changed the sensor under warranty with no questions. 3rd successful warranty replacement in the 2 year life of the car. It is always a pain when something goes wrong but having had 2 different sensors and a DCT gearbox replaced without hassle I am happy that Hyundai honour their warranty without question. Back to happy motoring again :)
