MT owners please help - clanking noise from gearbox

smknjoe · 11-01-2020, 01:27 AM

I can't tell much from the short clip the op posted.

Most manuals make a little noise when operating. Some more than others.

My 2020 M2C is no exception. I don't hear much when I'm inside the car. However, I have cameras set up around my garage and I can hear a little noise when parking on the video footage. Especially, when going in and out of reverse.

Normal

Edit: but yeah, if you still think it's abnormal for whatever reason...keep sending it back to the dealer.

Don't listen to the naysayers and second guess your attempt; it was worth a shot to spitball suggestions..

The forum and my vague description of a knocking noise, other members was able to help me diagnose a blown front strut, which I originally assume was a broken ball joint..

It's not unreasonable to post here for additional input. Dealers can be wrong or difficult lots of times and it helps to get a sanity check from the forums.

Here's a clip of me backing up. You can hear a clunk pretty clearly from ~15-20 feet away.

I can only hear linkage (shifter) making noise when you select reverse.

Part of your issue was noise when letting the clutch in and out wasn't it? I'm pretty sure mine makes a little noise. I'll see if I can capture that.

As for noise while driving and not shifting gears, I'd have to say no to that on my car.

To op any chance you can re upload sound clip? Service advisor in process of diagnosing and recreating the issue. If not no problem. Thanks

That is correct, clutch in/out makes the noise.

Thank you very much! I'll update what my SA says.

nnj3jnn · 11-06-2020, 01:39 PM

Hey guys just a update they couldn't recreate the sound so I just took the car back. Tbh the car drives completely normal and I rarely hear it so just going to leave it as is for now.

What an a-hole! What is the forum for then? Just cause you don't know stuff about cars does not mean the rest of us don't. Assuming everyone is as ignorant as you only makes you that much more ignorant. We have all had experiences with dealers that think they know what they are talking about or make you think that they do, in order to avoid paying for repairs. The forums and its awesome members are an invaluable resource for second opinions and to protect yourself from unscrupulous dealers.

They said that it is the nature of the car and it is normal.

To have a manual that you always need to think how to drive just to avoid the knocking... come on.

If i could try the manual before buying , there is no way i would have bought one.
I have had much chaper perfomance cars that you could shift by memory and smooth, and drove bunch of porsches ,and there was no clanking and knocking. in this car is hit and miss, very frustrating.

If you add: too long and light clutch pedal, rubbery feeling shifter, CDV, and auto rev match and adding gas in low rpm, experience of driving this car is total crap.

I usally dont like auto gearboxes, but in this case, sorry i didn't buy one .

ULTIMATE DRIVING MACHINE??? COME ON!!

Sorry for the frustrations.

Can you drive another MT with the dealer to actually validate that this is normal, or not? I wouldn't just take their answer if there truly is an issue.

It's not nice to call people names, even though that's what the internet is for.

I'd try driving another manual m2 if possible.

With cars, I've realized that sometimes it's best to leave a noise alone and see if it worsens with time or if you can better figure out when/why it's happening (e.g. weather).

Having a dealer start replacing some major components under warranty may lead to more issues down the road.

Car's will get squeaks, rattles, etc over time. I just get nervous when a dealer begins ripping things out of a car and starts replacing them.

Not saying you don't have a legitimate issue, just saying it may be better to take a wait and see approach. But it does require you to be less anal and I know that's tough to do w/ a new car.
