My 2003 mini copper the service engine light stays on, car is running OK?

Asked by zztap Nov 12, 2014 at 02:31 PM about the 2003 MINI Cooper Base

Question type: Maintenance & Repair

I put in a fuel injection cleaner in the gas tank with high test fuel, the good cleaner,
(treflon?) two days later, the service engine light stays on? When first going, it seems
a little slow, but runs great after I get up to 15 or 20?

This may be due to the fuel cleaner you put in the car,it may have up rooted trash,in your tank and pump,check the fuel filter,may be stopped up a little.

I had a feeling that I did up root trash! Thank You, It stated about 1&1/2 days after I put the fuel cleaner in.

also check the fuel injector micro filter.... if one gets plugged the engine runs lean and could burn a valve... (like me)

I recently took my 2005 MINI Cooper S convertible into a shop to replace the alternator. When I picked up the car, the problem persisted; no power and service engine soon light were on. 1 Answer

Now they're saying it's the harmonizing balancer sensor? What is this and is it true that they wouldn't have been able to diagnose the problem without first replacing the alternator?

My 2010 Mini Cooper S has had 3 thermostats replaced since I've owned the car (less than a year). Mini knows their is something wrong with certain Mini's. The check engine light stays on and only goes off a day or so at a time. The car has been fully checked and no one knows why the engine light stays on. After some research, is it possible for a bad wire that is attached to the engine light. I really don't know what to do. I don't want to spend anymore money on this car! 2 Answers
