More ML troubles, PLEASE HELP!
My wife drives a 2001 ML320 and the other day the speedo/tach needles started dancing up/down like crazy. Sometimes going up then down and sometimes not moving at all. Then several days after the engine light came on. Then the next day when we started the car it died. It re-started right away with a kind of rough idle. It would not shift into reverse so we did the pen trick and as soon as we got it to shift into Reverse or Drive the idle got really rough and it wanted to die again. Within the last two years I replaced the brake switch, alternator, plugs & wires. Now the car can be driven but I am not sure what other damage will occur until I figure out what the problem is. I got the following codes: P0130, P0136, P0150 AND P0156. THese seem to be the codes for the 4 O2 sensors but I am hesitant to replace all four since it is pretty doubtful that all four went at the same time. This is just another thing that the wife can complain about and try to get me to sell it and get a VAN. Any help will be greately appreciated!! THANK YOU!

That said, this forum is indeed a great place for advice and instruction, and if you decide to forge ahead and tackle this yourself, I wish you the best of luck and when you get it all sorted out, please share your experience with the rest of us.
I've only had my ML for a few months, so I'm still trying to sort it out.

So you call them stealers and rapers but you bring it there because you dont know how to fix it...... But you admit you would speend more throwing parts at it.
Your paying for experiance... Do you complain about your doctor charging to much or your lawyer... Cars are getting more and more complicated and you actualy need some knowledge to fix them correct....i think indys rip people off more..... dealer about 100-120per hr than you have over head, all dealers cost, loaners, training, SPECIAL TOOLS, diag equipment.. Indies dont even have close to the over head of a dealer and they charge 85-90 per hr Thats robbing you

Can't generalize like that, I know plenty of honest shops. They do charge upto $40 less per hour for the same work. (Specialty Mercedes Indy Shops_
Bottom Line, get two or three opinions, make a decision that best suits your needs and at least makes your ML safe to drive for your wife.
I do agree though that a Benz costs $$$ keeping it up to Benz standards.

I know alot of GREAT indies but i also know alot of bad indies... There are alot of mb techs on here that help with questions on there cars ... i even have driven and helped members with there cars but people are so quick to trash dealers like we set prices
But I agree its good to be in 'good spirit' with your local MB Service Department.
Also, an Alignment was cheaper at the Dealership then indy by close to 50%. Some indies will definitely try to rip you off. For example, got my tires from Tirerack shipped to local indy, dropped the car off to get the tires installed,(kumhos road venture), get a call back saying my ball joints were bad and that they need to be replaced in order to get the alignment done.
Well, bunch of BS, ball joints were fine.. IMO its all in who your SA is @ your dealership, it can make or break your experience, I'm lucky enough to be dealing with a 20+ year mechanic vet.

So do you know what crazy diag equipment they used to diag that problem..
A DVM or a multi meter and probably experiance of knowing what a over charging condition looks like. A dvm is 50$ at craftman and a amp clamp is cheap to...
When you do it yourself watch out for the lower bolt they always pull the treads out have a chase or tap set with you GL
