Hi all,
Used a OBD2 scanner on my car today and got the fault code 0170 and 0173 which mean the "right and left cylinder mixture adaptation reaches limit value". Does anyone know what this is as I am at a total loss. I have put some injector cleaner in with my last fuel up and I am wondering if that has anything to do with it.

Mass air flow sensor is going bad.. DO a search and you will see. I bet your above 75k miles arent you?

Yes up to 98000 now. Had problems with the MAF before but it was not replaced just checked as car started working fine. Guess I had better start saving up for one.

I got this today also. Glad it's just the MAF, I've read enough posts to know it was a matter of time. If this is my fix I'll send another post. only 65k miles but the car does run good, although I don't like the way it shifts(bought it with 55k). Makes sense by reding other posts.

Just dont try cleaning it unless you have the replacement Maf on hand, cleanung it might fix the problem or make it worse.

And don't go to the dealer for replacement. Try and find one on ebay or something. And then consult us or a quality MB shop to the replacement.

Replaced my MAF finally and fault code cleared. Got the MAF part number 113 094 00 48 from good old E-Bay for £80 ($148) with postage and had it changed within 15 min. Car feels totally different a lot more responsive to the throttle and it now accelerates as a V8 should. Its unbelevable how much difference a small piece of tubing with a smaller piece of wire running through it can make to this cars performance.
