new MAF = bucking and surging?

Thanks GermanStar... I'll let you all know how it pans out.

The correct Bosch part is 0 280 217 810; cross reference part: 1130940048. You may have the right sensor, but defective. Nonetheless, it should qualify for exchange. I bought mine here, and absolutley no problem. eBay Motors: Mercedes Benz Air Mass Flow Sensor C CL E S Class (item 130102187530 end time Apr-24-07 13:18:37 PDT)

The one on 03 has not failed yet but I was preparing for it . If it does fail, I will try an insert. That is why I was looking at the screws to see how to remove the insert.

I ended up cleaning it by removing the whole sensor with the housing. Actaully the sapy can reach quite deep into the sensor from the backside.

Yes, as I said, it is the correct part. Surprisingly, I actually had the wherewithal to add the missing zero.

You know, I've been hearing more and more good result stories from folks cleaning MAF sensors. Seems like a good way to go.....

FYI - the "5 pointed" Torx Screws are - Tamper-Proof TORX Plus, and bits are available, for example see Amazon.com: 11 Pc. Tamper-Proof TORX Plus Bits Socket Set: Automotive

Though I got my set at Autozone (special order, came overnight) for only $39.95.

I have a MY2001 S600, using MAF (Air Mass Sensor) A 113 094 00 48 - A VERY common Mercedes MAF starting from 1998 through 2007, and I believe it used a T20 or T25, Tamper-Proof TORX Plus.

This IS a relatively easy DTY Project - note that Siemens VDO MAF's are usually available in the $100 - $150 range.

Thank you,m norm1909, or the information on the correct name of the screws. Is your Autozone bits also SK brand?

[norm1909]

While certainly very late (Sorry), for those it may still help, I should have noted that for $39.95, I got only a 4 piece "no name" set - though they did trick. Got to love MAF's on ANY car, they are very precise, delicate parts prone to failure - and usually result in codes leading one to think their Oxygen Sensors, catalytic convertor, spark plugs, etc are the problem - wish I had a dime for every un-necessary repair a bad MAF has caused.

not sure how upto date this is.. BUT.... when i replaced mine.. it did the same... basically the car adapted to the old one for so long when the new one went on it SH*T itself

did just the same bucking, serging.. even mis-fired leaving grey (fuel) smoke behind..... i had th ewhole car RE_SET via mercedes specialist.. as in totally reset everything!!!!! and car worked like a dream.... the adapted car even went as far as shutting down my O2 sensors as they stopped switching....

But all fine now....... at 1st i even bought another MAF as i did the same.. thought MAN I BOUGHT A BROKEN 1.. no i didn't so i keep it as a spare
