Ok installed a new AEM intake and turbo oil line today. got it all back together. Then went for a drive down street and then it lost power and the yellow check engine came on. Pulled in to Circle K checked under hood To see that I was a Dumb A$$ and didnt put the cold side line back together. Popped that back on and tightend it down and the light still stayed on. She running fine now but light still on. What can I do about that. I tried to let car cool down and try again later and still came back on right from the start. any help would be great all new to mini's.

 

found nothing on 2 ODB ECU not giving codes.

 

You can either disconnect the battery to get rid of the CEL and if it comes back then you know you actually have a problem. Or just drive on it... and if it doesnt go away in 50 miles or so... then you also know you have an actual problem. It might've just came on because of the cold side not being connected and will take a few cycles to make sure everything is good.

 

Thanks droc I just let it be and it still didn't change so. I thought to myself that it running fine. So I just pushed it a little harder and then looked down light went off. :-) happy days thanks again for the response

 

Try looking for air leaks. Check the fit and Retighten all the bolts you removed and assembled.
