    Ok just had the EML come on, so took the car to a friend with a generic OBD reader and it came up with the codes

    P0035 (Turbo/Sup wastegate control circuit high)
    P0135 (02 sensor heater circuit malfunction) bank 1 sensor 1

    The car runs fine and boosts as it should.

    Does anyone have an idea as to why these codes popped up? Before i take it in for further investigation?

    Thanks

    P0135 (02 sensor heater circuit malfunction) bank 1 sensor 1- is the pre-cat lambda sensor, so its the one located on the downpipe. The error is referring to the heating element of the sensor. The issue could be bad wiring, so checking that might be your first port of call. When I had the issue, I just replaced it. It's 30 quid for the OEM spec BOSCH part from ebay (make sure it has the correct plug for your car). More details: http://www.obd-codes.com/p0135

    As far as the other code goes - I don't know, sorry
