Constant Bong noise SolvedSolved

Volkswagen Passat 2007 Estate/2.0TDI/DSG Auto 98000 miles
Just after I start up the car, a constant 'bong' noise appears. It stays on all the time in the background and remains on for a few minutes even when I switch car off.
There are no warning lights on dashboard and car seems to be running normally.
I have checked what I can and everything seems normal.
Any ideas?

This noise could be caused by a variety of issues, and it will be helpful to diagnose and repair the problem to ensure that your vehicle is running properly. Here are a few things you can try:

Check for any loose objects inside the vehicle. This noise could be caused by a loose object inside the car, such as a coin or a piece of paper, vibrating against a speaker or other hard surface.
Check for any visible damage to the car. The noise could be caused by something coming into contact with a moving part of the car, such as a stone hitting the underside of the car or a loose piece of trim rubbing against a tire.
Check the exhaust system. The noise could be caused by an issue with the exhaust system, such as a loose or damaged exhaust pipe or muffler.
Check the brakes. The noise could be caused by a problem with the brakes, such as a worn brake pad or rotor.
Check the suspension. The noise could be caused by a problem with the suspension, such as a worn or damaged strut or shock absorber.
If you are unable to identify the source of the noise or if the problem persists, I recommend having a mechanic diagnose and repair the issue to ensure that the problem is properly addressed and the vehicle is safe to drive.

Thank you for your comment but unfortunately it is none of the above.
This is a built in warning for something not major enough to have a warning lamp but is a regular, repeated, bong. Just loud enough to be heard inside the car. About once a second; bong,bong,bong,bong,bong... etc
It happens whilst stationary or moving and continues for a while after everything is switched off and I get out of the car!
Normally I'd have popped to my local garage but being the time of year...
In order not to damage anything, I'm trying not to use the car too much until everything opens up again on Tuesday. But if I knew the reason beforehand...
Thank you.
Bruce from United States 4 years ago
@MartynI see. In that case, please let us know what it was once you're able to diagnose it. And happy new year!

I spent some time with it today and found out that the alarm sound was coming from the dashcam!
I've only had it a couple of months and it seems that the microSD card causes an alarm to sound when it's full/locked/requires reformatting...
(a Nextbase 422GW if anyone interested...)

If Car has had impact damage meaning driveshaft snapped you could have damaged the transmission. Did you fit the correct replacement shaft ? It’s also possible the right side wheel bearing could be running rough. Hard to diagnose a fault you can’t see and hear. You could lift the car with 2 post lift or axle stands start it put in 1st gear then listen to if the noise is present and where it’s coming from. If no noise present most likely rough wheel
Bearing grating under load. If noise is present listen to transmission box and shaft bearing if it has 1. You can also check transmission oil level when not running... Hope this helps.

Noise coming from wheel

Volkswagen Passat 2018 manuel , sedan , 1.6 tdi bluemotion 22750 miles
A scraping sound comes from the right wheel when the steering wheel is turned all the way to the left. The car sat in a garage for a long time under the previous owner. Sometimes, the noise also occurs when driving slowly on a straight road. The mechanic said it could be a transmission or bearing issue. What do you think the problem is? Please help...

Andybaron from Great Britain 9 years ago
It’s a diesel could be many issues could be injectors could be egr valve all chocked up ( most likely fault ) could also be cam or crank sensor bad maf sensor is stronglt recomend use of good diagnostic equipment. To save lots of time and point you in the right direction. Could also be fuel pressure regulator. Just looked back it’s a 2008 it’s more likely to be dpf filter. And or egr valve hope this helps

Hi did you find out the problem. I just put a deposite on 1.6 tdi model and noticed it did d same. The dealer then got another car around and started it up and it did the same. Wudnt rev past 2500rpm. He said they are all like that when stationery.
chas. from Great Britain 9 years ago
All vw tdi engines are the same revs on driveway will not go above 22-23000 revs this was confirmed by my mot station it is all down to DPF it cuts emissions. [diesel particulate filter] when parked no need to rev the car up.

Noisy shuddering at rear end, even at slow speeds

Volkswagen Passat 2007 2.00 ltr saloon s.e.l. 93000 miles
Until four weeks ago, i would have rated my passat as one of the best,then during a mot, i was advised that the front tyres were going to need replacing. I replaced them two weeks ago fitting bridgestone 235 /45 / 17 to replace old michelins. As soon as they were fitted i noticed severe shuddering from the back end, with very uneven running back tyres goodyear 235 /45 /17, which seemed reasonably healthy. After having front tyres balanced for the second time, the problem refused to go away !! yesterday i consulted premier tyres, who said " simple you need new rear tyres !!! they were duly fitted, all the wheels rebalanced, and,guess what, problem is every bit as bad DOES IT SOUND LIKE SAWTOOTH ? if so what can i have done ??

If tires are believed to be good and balanced should rule out bad rim. Depending on milage bad wheel bearing or alignment may be a issue.

Strange noise

Volkswagen Passat 2010 1.6 Bluemotion  110000 miles
When I attempt to drive/take off in 1st gear I am hearing a
Strange knocking noise,. Once I have picked up speed and changed to 2nd the noise is gone... No problem in selecting gears, just this noise. The other day when I was changing gear I found a vibration in the clutch pedal. Anybody any ideas as to what this might be. No warning lights etc on dash... The mouse started 2 days ago and I think it's staring to get worse.

Sounds to me like your thrust bearing / concentric slave is failing. Easiest way to check this out is start the car and depress the clutch does the noise change ? Then release it to compare a good bearing should sound the same always pressed or depressed. Hope this helps
Rustle from Great Britain 5 years ago
I have a similar if not the same issue - when setting off in 1st gear i hear a grating knocking noise only starts when setting off in gear as i take the pedal up. I think its also in 2nd but hard to hear over the engine. It apears to be more previlant on an uphill start.

The sound coming from behind

Volkswagen Passat 2018 manuel , sedan , 1.6 tdi bluemotion 22750 miles
Sometimes, when starting to move or after setting off (it happened once while starting on a hill), I hear a knocking or thudding sound coming from the rear—though I can't pinpoint exactly where—as if an object were loose and hitting the vehicle's body. The items in the back are secured. Could this be due to a worn-out part resulting from the car sitting idle for a long time under the previous owner, or perhaps a worn bearing? Please help.
