Hi. Take it back, and/or get a second opinion first!

Hi, sorry to hear your still having problems, Im not a mechanic, a quick look up on youtube gave some potential problems that will set an engine light in the order i found on the video.

1/ mass airflow sensor dirty or faulty (+ check air filter and pipework for leaks)

2/catalytic converter fault-Full!

3/o2 sensor /sensors

4/ plugs & coils

5/ fuel cap seal damaged

an obd11 reader might help find a fault

i would also clean or  replace a "pcv"  crank case vent valve.

+ apparently cvt gearbox and speed sensor faults can also  set an engine warning  light

 Hope you can find a good mechanic to fix.

did they actually diagnose the fault, or stick a wet finger in the air?

There is a very lengthy thread in this Forum on E5 or E10.

Search for E5 E10 in the search box on your home page

 

I respectfully suggests you read it as there is quite a difference of opinions, including my own.

I think you posted an engine warning light problem thread before. The advice then was to buy an OBD reader. Did you get one in the end?
