After you saved all the money you may want to invest $300 for a SDS this will be the best investment you ever made if you plan on driving MB,a for a while.I just changed the spark plugs on my 09 GL 450 and I noticed the car jerk sometimes when I stop at a red light. Now the check engine light came on.
Anyone encountered such a problem before. Is it that I just need to clear codes?
That's what I paid, I used a computer that I already had, software and a VAS passthru device where just under $300.$300 is all for an SDS? I thought they were like double that, or more. Where should I go to buy one? Maybe I can be of help to other MBZ drivers in my area once I've got one. Plus, I have four Benzies here at my house so it would certainly come in handy. Wouldn't work for a Maserati though, I imagine.
SDS is a computer/system that plugs into your car's OBD port and reads codes, but the SDS is more than just a code reader and is specialized just for Mercedes Benz automobiles. It will tell you more, and do more than just a generic code scanner. Pretty handy if you have a Mercedes that you plan to have for a while, and intent to do maintenance and repairs on it yourself. Myself having four Benzos, probably should have gotten myself an SDS a long time ago.
My engine shut off at a traffic light and again when parking and I had a check engine light illuminated... The first thing I would do after the spark plugs, is clean the MAF (mass airflow sensor) using the proper exact cleaning spray product. Because of the size of these vehicles, it is not easy to reach, you need something to stand on but it can be accessed, removed, cleaned and put back. Use a code reader and clear the codes before start-up. Maybe your check engine light will go off and it will run fine again. If not, a new Bosch replacement is about $72 on Amazon, they have some other brands that are cheaper, but for me I would get the Bosch unit. I cleaned mine, cleared the codes (It indicated rich fuel mixture both banks) and it has been fine since. It's only been a day though. After a week of no check engine light and no stalling, I will declare it a success. If it acts up again within a week I'll buy a new MAF.
