All is Well - Almost!

Got my new ML 430 on Friday - great day to pick it up.

Have had a loveley weekend burning up gallons and gallons of fuel but I do have a problem it seems.

When I test drove the car, I booted her on an open stretch at around 40mph and she jumped down a gear or two, and lost all power. Couldn't get her going again properly and at idle she felt rough.

Told the salesman when I got back from test drive, who jumped into her, started her up and took off down the road with no trouble.

So as part of the deal I insisted that she went to MB or a specialist to be serviced/checked over etc.

Said specialist insisted on a variety of things being done, such as new discs/pads, tyre etc and sorted out a new mirror switch, an a service and most importantly fitted some sensors which were the cause of the loss of power. Cost the salesman 750 quid and I'm a happy bunny.

Only it appears the sensors weren't the problem. Once during the weekend (only once mind you) when I tramped the accelerator at about 45 to get out a lane and up a hill in wales the same loss of power occured

No worries though - pulled over, she was idling rough, turned her off, turned her on and presto all was well

I had pressed hard enough to hit the kickdown button under the accelerator so I don't know if that was the problem?? (Did it before the event and she was fine from a standing start - hyperspeed achieved no problem)

Any ideas anyone?

Oh and one other thing - where can I get another remote type key? Only got one

Why not unplug the MAF filter and see if it runs better or take it off and clean it as the threads here. the engine may run a bit rough with the MAF unpluged but your other problems may go away. You ca buy a Bosch insert for a fraction of the price of one from MB

Sorry forgot the key,only from MB,take your passport and log book with you.

Thanks - is the MAF the same as a MAS? And how much is it going to cost the garage that sold the car to me?

Yes it is the same thing. from Bosch £58 from MB £250 + fitting. from Bosch you have to use the existing plastic housing,and there is nothing wrong with that.

Does removing the MAF affect fuel consumption? - I ask as the car went back to the garage and was "fixed", all being well power wise, however she now runs slightly rough on startup when using petrol and I seem to have poorer fuel consumption. I'm wondering if they have just took it out!
