My car still does this: when stoping and the engine is still running, I can feel the car like it is shivering off an on. The car does no hesitate or anything, it runs great but only when stoping after being driven. What could it be? Could it be a fuel filter needing to be replaced? The car has 47k miles and always use premium gas 92 octaine.

E320Star

could it be the after market airfilter?

It is occaional shivering. It appears to happen whenever the temp outside is below 50F.

Well, anybody !!!

Pulleys? Harmonic Balancer?

E320Star

I have no idea what you said. Please in plain english. Thank u

eLemnt | 0ne

I use to have the same problem as you, except in my 202... Went to the dealer and changed the pulleys (the rubber band thingies in front of the engine under the hoood) and changed the harmonic balancer (which I forgot was)

I suggest gettin it check at a local mechanic or stealership; thou I don't like going to them because they are so expensive.

But yeah, it's most likely the pulleys.

When your car is "shivering" what is the RPM doing? Is it jumping up and down with the "shivers?"

My mom's '00 E320 did that for a while also, and it progressively got worse, so we took it in. It happened when the engine was cold in our car too, but the RPM's always remained consistent at idle. The service manager said that he was almost 100% positive that it was the catalytic converter, but it turned out to be both engine mounts were "collapsed". There's no vibration from the engine now, but once in a while there's still an occasional shiver through the steering wheel, but not nearly as bad as it was.

Sorry I can't help here as it could be a number things.....it would be dangerous and costly to start guessing.

However, you got K&N? Did you check your car's blood cholesterol...ooops, I meant silicon and metal levels lately? (oh BTW, you will definitely find traces of metals in your oil.....the pistons do wear down, if you catch my drift).

Are there any codes or a CEL?

Try going back to a stock paper element air cleaner and at the same time, remove your MAF and being very careful, clean it. Hope you kept the original element and did not throw it away.

There are spray on cleaners that will remove any oil that may have come off the K & N (oiled) filter.
It doesn't take much to coat the fine element in the MAF and mess it up.
This is what many individuals were experiencing on their TDIs.

It's worth a try isn't it? Relatively easy to do and not expensive because you can do it yourself.

Good luck, and I HTHs

what year is the vehicle? does it shake the most at 1st or 2nd year? and does it not shiver at all at neutral and parking? if so i think i know why

regards,

Whitey

OK Mr Green E, although we have somewhat agreed to disagree on the other threads, here's my attempt to make peace - in the interests of the harmony of this community and I am really tired of the pointless whining, and I'm sure you feel the same way too. What you said is pretty much one of the things I had in mind but it is just one of a few things that could have caused the shaking, and I trust with your experience, you would agree. And I do agree its worth a try as it doesn't take that much to do and worth it just to prevent a total MAF failure - which could be costly. But don't you also agree that we need more info to get to the root cause? As I said before, I really don't swear by the K&N but it definitely has not caused me or a number of other people such problems, so it is still possible that it's one of the other causes too, right? Peace out and lets try to help E320Star solve his problem, yes? I hope you do not find this offensive in any way whatsoever........

E320Star

The RPM is stable. no ups nor downs. The shiveris not all the time.

E320Star

It is 2000 E320 with 47 k miles. It shivers only in D drive and only hwen temp is below 50F. In warm wheather it runs perfectly. The engine is not shaking at all, the RPM is very stable. It does not shiver in N nor in parking.

Whitey

BTW, did you not end up going with a paper replacement filter instead of a K&N, only not an original MB one? In the absence of oil coming off the filter and based on your updates, the MAF may not be the issue (but nevertheless, still a good idea to clean it every now and then to prolong its service).

E320Star

I do not have K&N nor the original MB one. I replaced with an after market paper air filter. The new paper air filter was installed 2k mile ago. Last weekend I removed the filter and wiped the MAF clean and vacumed any dust. It is spotles. I wish I did not throw away th eold MB Airfilter to see any diff.

Green E-300 DT

It would seem to occur only when under a load. How about when it is in reverse?
Iin drive, does it matter whether it is in "W" or "S," as I was thinking the load factor might just make a difference, as you have said that it doesn't do it at all when in neutral or park regardless of the outside temperature.

How about when the outside temperature is lower than 50 degrees Fahrenheit?
This is happening only when the car is first started up, or does it still continue as the motor is warming up?
And when it reaches full operating temperatures, is it still occuring?
It absolutely does not occur when the outside temperatures are above 50 degrees.
That's a strange one indeed.

It could be those motor mounts, but I'm inclined to suspect the MAF, as your
outside air entering the air intake won't change that much as the engine warms up.
Because the incoming outside air is of a lower temperature may be causing
the fouled up (if it is bad) MAF to cause unsteady readings to the ECU.
This is only an educated guess on my part, so consider the source.

When you cleaned the MAF, how did you clean it?
Did you simply wipe off the black plastic surfaces, or did you actually clean the fine wire element?
Was there any dust on those surfaces?
It is very difficult if not impossible to clean the MAF properly without removing it from the engine bay.

If not the MAF, my second guess would be those motor mounts.
But given this temperature factor, I don't see the problem being with them.

I had heard that the motor mounts and balancers were a problem only in the
earlier model W-210s equipped with the straight, not the V6 motors.

If you have any way to have anyone check it to see if there are any stored codes, try and do so.
Some of the popular parts houses will do this gratis.
Worth a shot when one is trying to save a buck, no?

A plugged Cat. or your use or not of higher octane fuel shouldn't make any difference, at least when idling.
I keep reflecting on that low temperature thing.

Try cleaning your MAF again, and see what happens.
Before you remove it for cleaning, and when it is doing the "shakes,"
simply try unplugging your MAF and see what happens.

Perhaps Freshyip has the answer?

We are all simply fishing here, and as they say, any port in a storm.

Being "shade tree" mechanics, we do what we can.

It'll be interesting to see what you do discover.

Put us all out of our misery and take it to the dealer for a diagnostic evaluation. Sometimes ya just gotta spend a dime.

E320Star

It doe snot do it in reverse either. It does not do it when it is cold. Only when it is warm and in stop postion on the D. It makes no diff if S or W. And it happens when temp is below 50F. Today is 57 down here in KC. It did not do it today at all. I checked the Pulleys, & harmonious balancer and all the rubbers, all look pefectly like new. One thing I am trying right now, I put a lower octain premium unleaded. Usually i use Amoco 92 octain, today I filled it up with Quick Trip Premium unleaded 91 octain. The shiver appears to go away, but again today is above 50 F. Tnight and tomorrow the temp should dip down a little. I iwll keep u posted if this takes care of it.

Green E-300 DT

Changing fuels won't matter. It cannot be fuel related.

Take the time to remove the plug on the MAF while it is doing it and see if it stops.
If it does stop when the MAF is unplugged, there's your problem!

Then remove that MAF and clean the tiny element(s) inside with diaelectric cleaner.
If that doesn't fix it, then you'll have to spring for a new MAF.
Getting one yourself is a lot less expensive than going to the dealer and having them do the entire procedure.

It's got to be the MAF. If not, what else could it be?

dear all,

about a year ago i have discovered the car was almost about to dance just like how taxis do at stop lights haha, i have looked around the car but don't find anything unusual until i had to ask my uncle which was a ZF certified MB mechanic of HK, but now works for Porsche and Renault of HK. He said Usually >320 engines are typically heavy and once reached about to 40000 to 50000 km in mileage the pieces of rubber that supports the motor (the pieces of plastic that is between the motor and the X support of the engine) will eventually wear out. Thus he took the car for a spin and then soon he replaced the pieces of plastic and showed me the ones that wore out. A new piece is about 2 inches thick while the wore out ones ended up having about 1.5 inches. Thus ever since then the shaking matter has gone away for good.

i cannot say i am 100% sure this is is the problem that causes your car to shake, but there might be a chance

anyhow, good luck!
