Car only has 2200 miles on it and during a recent drive the Service Engine Soon light illuminated. I've searched the threads concerning this issue and am familiar with most of the likely causes (wiring harness,02 sensor, gas cap...) I was wondering if anyone else here who owns an '06 MCS has experienced this and if so what it was. I will be taking it in for diagnostic this week.

 

My light came on when my gas cap wasn't sealed all the way. Once I opened it and reclosed it - with 10 clicks this time - my light turned off.

 

Does the amount of times you click the gas cap actually have an effect? or was it just for good measure?

 

Take you mini to autozone and they will pull the code for you for free...I had to do that before I bought my own reader. Once you get the code then report back and we maybe able to help more! -- Johan

 

It's like saying 10 Hail Mary's (Hail MINI's) to atone for your sins. . .

 

CEL could be on for a lot of different reasons...

Get the codes out and you'll know why yours came on.

I also suggest you to get an ODB2 scanner tool... It's a very useful device and worths it!

I bet it is an 02 Sensor. I have had 4 replaced already in my August '05 MINI with 14,000 miles. The first was replaced at about 2000 miles.

 

Started car today and no service engine light. Should I still try to pull the code and/or take it in to the shop?

 

It could of easily been a bad reading on one of the sensors. It if cleared itself I wouldn't take it in. Although around here the dealers are so backed up for service its almost impossible to get in for a quick code check

 

It might have been your gas cap -- that SES will clear by itself after a few start cycles. I wouldn't worry about it unless it comes on again.

 

I'm going to buck the trend and disagree I had a bad O2 sensor that woul come and go, for a good 10k it was intermittent, go get an Autozone reading ASAP, even if the light isn't on many times the code will stay in memory for a while, it was a code that was hard to catch that convinced me to purchase an OBD scanner myself.

 

My SES light came on about a month ago. I took it to the dealer b/c I needed to have my NYS inspection done also. Anyway, the MA said that it was a misfire code and, because it had only happened once, that it would have eventually cleared itself.

Then on Sunday it came on again. The car was driving fine, so I figured I'd give it a couple of days. When I started the car after work on Monday the SES light was not on. So, I figure it was another single misfire incident. Like many of you, though, I'd feel much more comfortable if I actually knew for sure what code it was.

 

I just had the same problem. AutoZone said the code was from the knock sensor. Something about reading low...does that make sense? Any ideas about this one?

 

Came on again today. I'm going to Helix tomorrow for some other things, I'll have Eric check it out.

 

Eric pulled the code and found it was the knock sensor. He cleared it for me and we're going to see if it comes on again. If so he'll replace it as it is most likely a faulty part. I'll keep you posted. BTW, I put on the M7 strut reinforcement plates for some added protection from the mushroom plague.
