Looking for some expert opinions. I have an 00 e55. About a year ago, the car was behaving odd -- overly sensitive tip-in from start; too early 1 to 2 shift under low/med acceleration; not enough torque to spin the back tires from a dead stop (w/ ESP off).

Took it to the dealer who found no codes but replicated the symptoms. They eventually replaced the air flow meter which fixed the problems.

One year later, I have the same issues but the dealer insists "everything is in tolerance and there are no codes". They also insist that an e55 should not be able to spin the tires from a dead stop!! I asked them why it used to melt the tires down w/ the ESP off. They said "it could be that the tires are now more broken in".

Looking for a sanity check and some suggestions. Shouldn't an e55 have enough torque to break the tires loose? Any clues how to advise MB on additional things to look at? Additionally, I am on my third air flow meter. Any ideas what the cause might be??

I have had similar problems....make them replace the mass air sensor again. You are not insane...you should be able to spin the tires ALWAYS with esp off, dont let anyone tell you different. Good luck.

Bad MAS does not give any codes. You should be able to spin the tires. Get a new MAS.

Is there any way to diagnose a bad MAS other than "it won't roast the tires"?

I've noticed my W210 E55 is a bit touchy on the tip-in, but I've only had the car for a few weeks, and figured it just was a characteristic of the drive-by-wire throttle.

It also won't get more than a little slippage with ESP off, but that may be due to brand new S-03's. They're pretty gummy, especially when new. (not that I'm looking to burn off the tires, just want to make sure it is running up to par).

Any suggestions?

Thanks for the replies. The last time they replaced the MAS, I went for a test drive with the tech.

I popped the ESP off at the first red light. When I saw green, I mashed the gas pedal and the e55 instantly and ferociously lit up the tires. Out of the corner of my eye, i caught the sight of a poor soul waiting on the corner bus stop bench, who upon hearing the sounds of the roaring engine and smoking tires, leaped back into the hedges behind the bench.

That is the performance I am looking to recapture!

The e55 is an amazing vehicle and more than a bit addictive. I have been into performance cars since getting my first 69 Z28 while in high school in the late 70's. In the early 90's as a family man in need of four doors, I was elated with the introduction of the Infiniti Q 45. The idea of a massive 4-door sedan that ran sub 7 second 0-60's seemed remarkable (at the time!).

Wind the clock forward 10 years and we now have e55's running mid 4's 0-60's, and 12.4 in the quarter. This all makes my 00 e55 seem a bit pokey and my Q45 positively nostalgic!

Until my lease expires, at least you have all provided me with some hope that I can in fact milk a few more blue smoke-outs with a new MAS.

Thanks again. Motorbobb

BOB...I have had a few trips down the strip before...the best has been a 13.36 @ 106.6 mph...remember the sub 13 sec timeslips are from the w211 E55 not ours.

Not bad... Is that stock?

Get the Kleemann kit to end all this! :p

Of course....only change was K&N air filters.

Is it normal for ESP to activate when going from a stanstill around a corner in W mode? When I first drove a W210 E55, I was amazed with its power!
