Warning Lights And Radio Problem

Hi Guys

I tried searching but cant seem to get the search function to work.

On motorway today and got 2 warning lights accompanied with the radio not working. Book says lights are dtc problem and no puncture warning system (which is tied in to the dtc i know) Car runs well with no issues. Turn off and on and it all resets but comes back intermittently.

I had the ecu remapped saturday. Could it be due to that or just a coincidence.

Any help gratefully received thanks.

    Not a coincidence with remaps matey... Has to be connected to OBDII to re-program the map in situe, sometimes a default map is used then the timings-fueling-spooling times are added to that map often not including updating the vehicles' variant settings like cruise, security, auto-windows etc...

    Took it back and he reset it and said its normal and sometimes plays up but will sort itself out. Hasn't come back yet so will keep fingers crossed.

    It could just be the car actually in "Learning" mode to adapt to your driving style etc... BUT...

    That remap should not touch entertainment systems unless they had their own map to use, making their map overwrite yours!!

    The thing is, if everything worked fine before then their mapping has caused your issue(s) ;)
