Scooter rattling noise when idling

Noises "metallic rattling or knocking" when starting

Hello @all

I need your help.

With my B200, model 11/2011, there are more noises "metallic rattling or knocking, rattling" when starting from the engine compartment.

You can hear this very well because it is quite loud. The whole thing takes about 1-2 seconds and occurs when the engine is warm or cold. It sounds like a lack of oil pressure on the valves to me.

My neighbors were already asking if I had a diesel!

The workshop said the noise was still normal, but it is not for me. It wasn't before. He has now run about 16500 KM. The strange thing is that this noise does not always occur with every startup process. For example, it never occurs when starting the car with the ECO function.

So it starts somehow faster or different.

Who can write me something about it or who has the same noise or is this noise really normal when starting?

First of all, there is enough engine oil that MB checked first.

Thanks in advance for your tips

Hi Verena,

Hello the rest,

my wife is just leaving the workshop today with our B180 (W246) petrol engine.

We also have this "metallic" rattle after starting, usually 1-2 seconds. But it was already so extremely long from time to time that I got out again to look into the morale room to see if something was vibrating, also shaking the exhaust system. Only after the engine was switched off and restarted did the noise go away again.

That it takes longer than 1 to 2 seconds is rather rare and so far only noticed in a cold start.

Now back to the workshop visit.

So yesterday, after making an appointment, I brought the car to the workshop and looked at the problem with the master. Of course the demonstration fect nothing happens. Left the car in the workshop. Stayed with the really nice master in such a way that they keep the car there until the error occurs. Let me have a C-station wagon as a replacement for the B180. (Thumbs up).

Then this morning the callback, the error has been narrowed down, they brought in an expert from the MB plant in Sindelfingen who probably already knows the whole thing to such an extent that it can be narrowed down to two causes of the error.

The foreman told my wife what it is, MB already knows the problems, but nothing can happen. All right then. We have agreed that we will shortly be going on vacation for 3 weeks to hand in the car there until the cause (s) have been resolved and they have enough time after the repair to test whether the fault has been resolved or not.

As soon as I have precise information about the cause and how it could be rectified, I can report about it again.

I have to say that I have visited the workshop several times and have always returned home with a positive impression and result, as has been the case in this case until now.

Hi,

Is it a clattering, irregular noise that occurs in the coolant temperature range between 40-80 ° C when the engine is idling? With increasing speed it becomes quieter until it can no longer be heard from 1000 revolutions?

As a remedy, the engine control unit should be flashed with the current software.

Greetings Dirk

Hello Dirk

Nah, the noise is only when the engine is started for 1-2 seconds. Once he's running, it's quiet.

In any case, you can't hear anything in the interior.

As already written, it sounds to me like valves that run without oil.

Thanks for the answer, then at least I'm not alone with the problem.

Hi Ale_ks,

my parents also have a B 180, 3/12 first registration. You have the same problem, a rattling noise from the engine compartment for 1-2 seconds. What did you do with your B-Class? My parents have already made 3 visits to the workshop and all of them without success. The first time they installed software. in the second, the chain tensioner was renewed and in the third, the two camshaft adjusters were renewed, each outlet and inlet. Everything without success!

It would be nice if you could tell something whether the noise is gone and what they did with your B-Class!

Thanks in advance!!!!

Hi good afternoon

The described NOISE is very well known at VW and the 1.4 liter TSi engines under the term

"Chain rattles" (googling). It got me too and that was one of the reasons why I changed brands. But I can say that VW was very accommodating to the problem. The following was changed: chain tensioner, camshaft adjuster and chain. The work and a share of the material costs were carried out over a period of around 80,000 km.

So I know the problem of the demonstration effect very well. The rattling was only audible when the engine was still cold for the first time and only 2..3 seconds. Then when the engine was warm (issue ECO Start) it was no longer reproducible. I now hope that things will not go in the same direction again and that the engine problems will repeat themselves from my point of view, even if my Benz 1.8 liter diesel does not yet have it.

I think with a diesel the NOISE would also be much less audible.

Hello everyone,

I also have the rattling engine on my 11/2011 200 gasoline engine blue Efficiency, 6 gear. However, it usually only occurs when the engine is cold and it appears as if the engine is without oil or the starter is not properly engaged? It also appears that it starts a bit at high revs. As if you pressed the accelerator down beforehand like in winter. Already had an appointment but then it got too hot. So wait a little colder days or when I can learn a little more.

Hello everyone,

so, now I'm back from vacation ...

So, they told my wife in the workshop that the tensioners and the timing chain were exchanged, as far as she understood.

Then the next morning at home in the garage the rattling for 1, 2 or 3 seconds.

My wife back to the workshop. The car stood there for about 30 minutes and the noise was reproducible. Now we have a new date, the Moror is to be removed, and parts of it are to be dismantled and exchanged. A specialist from the MB plant in Sifi was also brought in to support the procedure. Unfortunately, my wife did not understand most of the technical conversation.

So, now I hope that this will be the final workshop visit on the subject.

As soon as I have something new to report, I will announce it again in this group.

Hi Ale_ks,

is now a result ????

Please provide brief info...

Thank you

Hello,

had this short rattle on my 200 gasoline engine as I said before. It stopped now after I switched from E10 to Super. Although approved for E10, the engine now runs better, smoother? Somehow inexplicably the transmission shifts softer, apparently there is a sensor that detects which petrol is being used.

My camshaft adjuster was changed.

But it didn't work ... Still rattles on cold start.

I want to return the car, but the dealer gives me a price that is too low for me not to be able to buy a comparable B class for this money.

I am now trying through my lawyer .....

I have already read a lot that other manufacturers VW e.g. from such a rattle engine damage resulted .....

Such a shit that I can't even get a comparable car or money for it .....
