Sometimes if I'm taking a corner, and hit a bump I feel like the back of the car is going a different way to the front.

Is this what they call fish tailing? Normal?

Should I just stop accelerating around corners?

My Tire pressure is currently 33psi in the back and 31 in the front, I'm going to raise them!

I used to have this "2 direction" movement on my old toyota, but I didn't expect it on my E class!

if you keep accelerating, you might have some issues. slow in, fast out should be ok.

You need a few more pounds....I meant tire pressure.

Shouldn't lower tire pressure hug the road even better? But yeah, your pressure is too low for this car.

That's weird. I've never gotten even near breaking the tail out in this car, in fact, I figured it's probably almost impossible, with all the traction control gizmo's and such. Sounds a bit odd to me, are you super aggressive on the pedal?

I'm not sure! It's almost like if I'm going around a corner now I'm afraid that it 'wobbles'.

I was reading a forum about someone with a mid steer wobble; and he said by changing his coilovers(whatever that is) it was solved;and then someone suggested a Damper problem(is a damper a shock?)

I mentioned my 'steering' creak in a different thread; is that normal early in the morning?
My gear box almost makes a funny click when i take it from P to D, or to any other gear, by my glass must me down for me to hear it!

I'm think i'm being paranoid

I mainly get the issue if I hit a bump or noticable discrepency in the road.

It is not fishtailing. For normal daily driving, it doesn't have much to do with traction.

It is not a normal trait for a car, but this issue for the E550 (dunno about the 350) has been discussed in the car magazines. Basically, the reviews said that this car is not fun to drive on a bumpy track because it gets nervous when hitting bumps in corners. Comparisons to the BMW 5 said that the latter did not suffer such problems. The E550 likes smooth corners.

Nervous here means that you set the car for the corner (get the body leaned over and settled on the shocks) but a bump causes the car to start bouncing all around. There's lots of weight transfer. On a racetrack, at the limits, this would be bad. Not so much for daily driving, aside from discomfort. A normal car would not have nearly as much weight transfer.

BUT, I think it might be a software issue. I have a long sweeping curve in my subdivision that I need to drive every time I leave. In the middle is a bump. Most of the time I can avoid it, but on odd occasions with traffic, pedestrians, etc., I can't. I had the car for about 2 years, and it did exactly what you describe. At my service B, I had all the car's software updated. It doesn't do it anymore. I vaguely recall seeing a TSB that connected the software to suspension issues.

I hear a click every time I put the car in D or R with the windows down. Normal, I think.

Run 30 on all four corners on the wife's luxury with 17" wheels. No problems.

W212 is designed with some understeer which tries to prevent the tail from oversteering the front. That's why you don't have to fight to recover from traction lapses like you seem to be describing.

This understeer is what keeps the W212 from being called a true "driver's car". But it is the same thing that makes it a safe, fun car.

After a run the PSI is 42.5
Normal?
