Adam rs Posted March 31, 2013 Share Posted March 31, 2013 Not used the car for about 2 months,Had to disconnect the battery for about an hour yesterday to put a bit of charge into it.Fired up first go as usual and has been fine on the 2 subsequent runs to the shops and for fuel.However i have noticed that the car seems quicker than i remember just as it did before mapping adjustments were made for the Berk HFC's when it was running very lean.Ive been to the malton breakfast meet this morning with no issues and covered about 150miles since i had the battery off.Coming home from the gym tonight i got about 5 miles and the engine light came on.This has never happened before and the car is babied all the time it has wanted for nothing .Im wondering if a hfc has collapsed (I have no change in performance or tick over) and the ecu has detected an emissions fault.Or that the uprev has been somehow upset by me removing the battery and has leaned things off back to a previous map and upset the ecu. I will have access to my obd scanner tomorrow,but wondered if anyone has any thoughts? Quote Link to comment Share on other sites More sharing options...
glrnet Posted March 31, 2013 Share Posted March 31, 2013 You won't upset the uprev by disconnecting the battery. Quote Link to comment Share on other sites More sharing options...
Adam rs Posted March 31, 2013 Author Share Posted March 31, 2013 I wasnt sure if that was the case.Thanks. I will delve a bit deeper tomorrow then,Hopefully something of nothing,Spent all day telling my mates at the show how reliable these cars are!!!

glrnet Posted March 31, 2013 Share Posted March 31, 2013 Not unusual to throw a light randomly, try an ECU reset first. Quote Link to comment Share on other sites More sharing options...
Adam rs Posted March 31, 2013 Author Share Posted March 31, 2013 Done ecu reset. Been round the block for 10 minutes. Light still off,I would have thought it would have come back on if there was a fault. Fingers crossed. Quote Link to comment Share on other sites More sharing options...
glrnet Posted March 31, 2013 Share Posted March 31, 2013 Should be ok, can happen every now and again Quote Link to comment Share on other sites More sharing options...
Adam rs Posted April 1, 2013 Author Share Posted April 1, 2013 Had OBD scanner on her- Heated O2 sensor 1 Heated 02 sensor 2 Maybe sports cats threw it on. If id have had de-cats the light warning for this would have been disabled on the uprev. Light not been back on,all seems OK! Quote Link to comment Share on other sites More sharing options...
