I purchased a Used 2007 Mercedes-Benz E 350 4MATIC Sedan, drove it home and realized when I took foot off the accelerator, there was a whistle/chirping noise. Any idea what it is? No the AC was not on.

Thank you for your quick response. At 78 and only having much older MZB, I was worried having just bought this without a warranty. Is this hard to fix? Thanking you in advance.
At 78 you need to get late model Toyota with warranty. Sit in your backyard and watch Red Robbins feeding their young.
Hell with working on 13 year old car. :)

Maybe, but have had MZB for decades. The recent one 1988, with only 145K miles was totaled last week; the driver walked away, the truck that hit it was damaged more than my car; spun the truck around. The one before that was a 1994 MZB 300 that had 500 miles on it; still excellent condition and gave it to wounded warriors. I would have preferred an older MZB without all the electronics but bought this one. I still have years to go to try and make this a better world; help people to "get right before they get left."

Your old w124 to a 211 is light years in terms in safety, that鈥檚 the truth.

near impossible to diagnose from your description...is your 2007 in the bad engine balancer range? (Google search 211 engine balancer if you don鈥檛 know what this is as it can be an engine removal requirement if you get the CEL code)

What mileage on the car?

what speed was it doing it?Could it be rear differential whine if that was freeway and you lift the peddle? Is it repeatable?

Thanks for responding. I'm at the mercy of God and the individual who finds the problem. As an old retired nurse, I want safety. It has 214K miles-no problem for MZB if well taken care of. It the whistle/chirping-can't describe the sound is when I'm beginning to drive slowly and then de-accelerate. Not on freeway if I'm keeping constant speed. In town driving it is most noticable. Again, thanks for your help. Oh, regarding "engine balance," I apoligize, have no idea what you are talking about. I pray there is an honest mechanic in this area.

How about you spend a little more time researching a good mechanic than you did before buying this car. A bad mechanic will drain your wallet in this car. A good mechanic won't be cheap.

We can certainly help you get started in that respect. First off they should be a modern Mercedes specialist. Does their lot have lots of old inoperative cars?, run away! There should be cars of your age and condition in the lot. Ask them what star is. Then if they answer that, ask what scm coding is.

If they don't understand and have the tools to diagnose your car then they will replace parts until the issue is fixed or your wallet is drained.

And yes you should take the car back and buy a Camry.

Hindsight is good; I needed one and it was without warranty. I was looking at another 1988 with the intention of replacing all the fluids, hoses and such, and will do it with this as well. (Hard to tell a woman what to do; especailly after she has "messed up.") Have set up an appointment with an Auto Service that speciliazes with MZB and had 5 star rating with says "Repair Pal certified." Does this mean anything? I appreciate your comments.

There are plenty of well reviewed shops with bad mechanics but it seems like you are going in the right direction. Can you post a link to the place you are thinking about?

Also if there is a Mercedes dealer close by, find a coupon for their oil change special. They'll do an inspection on the car and find a ton of stuff wrong, most that you can live without fixing but it will paint a good picture of what you've gotten yourself into. They are probably more honest as a general rule but expensive and try to restore the car to perfection. We can help pare down that list.

Point is these cars are very specialized and need proper diagnostic tools and training for fixing real problems. Routine maintenance can be handled by any cometepent mechanic.

x2 on checking the engine for balance shaft issue.
Tracking engine noise can be a nightmare, but retired nurse should not have problem using mechanic's stethoscope?
On 4M keeping eye on CV joints/boots is good idea.

Problem is you're confusing a 214k car with reliable and inexpensive. You are going to have problems, you are going to have to spend money, if this isn't going to work on your budget, this isn't the right car.

On the "plus" side, at 214k I doubt the balance shaft is overly concerning, its either out of the engine range entirely, or its one of the lucky ones that won't require a $3-4k engine removal & repair.

The place is Holly Tire and Auto Service in Holly Michigan. I have steak desires on hotdog budget, but my ex purchased this for me; knowing I wanted the protection. (As I said before my last one-1988-was hit by a truck; truck spun around; the car totaled, but the driver walked away with just bruises.) I wanted an older model; less electronics, and maybe I bit off more than I can chew, but I put little miles on a car-maybe 3000K in three to four years. I have seheduled a free inspection from them; awaiting the time set and then go from there. Yes, there is another further-MZB dealer, but not only expensive, refuse to sell older used MZB and treat you according to what you are wearing and what you are driving. (Hate this in people.) Plus their prices are much higher than expected; the wealthy can afford it; I can't. A small town with good ratings is what I want. I did read the comments and impressed with what was said; the "machines" they have on hand, but always willing to listen should you choose to check them out and let me know. Again, thanking you for your time and suggestions.

Thinking of having it checked over; fluids replaced, hoses and such if necessary. Strange, I invented a stethoscope called the Ultra-Scope stethotscope, and did hear of people using stethoscopes for cars; but I'm not that smart. (I would still have money if the "partner" had not stolen my company.) I find it sad women are taken advantage of by so many who are in it for the money and not quality help. This site I am finding to be genuine concern with helpful comments. thanks.

I pray that isn't the case either. Maybe God will have mercy on me and make it not expensive. But I gave it to Him on the way home, and now it is His problem. (Yes, I will have to pay.)

I pray it isn't. The two I had before 1988 with 145K miles bought used, and 1992 with over 500K miles used; never had a problem with either of them.

$5 buys you this at Mechanic's Stethoscope
Also you bought digital car, what I also like to call "computer with wheels". Regardless if you plan to DIY repairs, or take it to a shop, to avoid being taken advantage off, you should troubleshoot at least the digital side.
MB -oriented scanners used to be very expensive, but lately walmart is selling very good android dongle for $50 https://www.walmart.com/ip/Autel-HT...CAN-Bluetooth-All-Systems-Scan-Tool/964022238
Consider buying it.

I looked up that place. Looks like a mom and pop basic repair place. Good for simple things. I didn't see an European cars in any pictures. Just beat up American cars and a Toyota.

It's times like this I wish I were younger. Will look into this; thanks for the tip.

Have called and left message. Would you believe this morning went out and a large nail; had the tire fixed. Two certified mechanic students-almost done-told me they thought it was a "brake bearing" or something like that. In the recesses of my brain the sound was when I heard decades ago, like sliverware. No, not pads. Does this make sense? Again, thanks for your help and comments; most appreciated.
