SES Light - Silly Owner (Me)

[AquilaBMW]

So, today I decided to change the Lower Timing Chain tensioner on the X. What a Royal PITA it is to get to it. Talk about tight spaces.

Anyway... I was able to somehow get it done. I started the car, but forgot to plug in the MAF. I was about to drive off - all the while wondering why the car's idle sounded weird - then the SES light came on. Right around the same time I said, "Crap! I forgot to plug in the MAF!"

I am assuming that is what triggered the SES light. If so, will it eventually go off by itself or do I need to go in and scan it first?

After you drive it around and if that was the problem, the light will go off. If the light remains on something else is the problem.

Uh Uh - Got something else wrong then. I drove it about 20 miles and parked it for about 30 minutes. Light is still on...

Thankfully most SES issues can be read with a cheap scanner, which Autozone or other parts stores will do for free.

It generally took at least three start stop cycles with a good amount of time in between before my ses would clear itself.

I hope it's nothing serious, need the car for a road trip. Thankfully I have INPA and DIS so I will scan it tomorrow.

Let's hope that happens with it. I will scan it tomorrow just to be sure and to be safe. Thanks!

Unfortunately Aquila lives in California & they don't allow stores like AutoZone to do free scans.

If the MAF set the OBD fault code...and you plugged it back in, then drove around...but the SES light is still on...then your drive didn't cover the requirement needed in the "drive cycle".

OBD II DRIVE CYCLE
