Check engine light, 2010 S3, 61k

[Alas]

After the 'big' service, engine check light comes on after a few miles.  Fuel filter and Lambda sensor changed, no different, and no other symptoms.

Any ideas, please?  Serviced for 8 years by reliable independent.

If the light appeared immediately after the service I suggest you take it back to the garage. They may have simply forgotten to reset the service warning.

Hi not resetting the service light would not put the EML on, just take it back to the garage and get them to plug it in might be they forgot to do the adaptation procedure on the Lambda sensor after it was fitted.
