thump

I have noticed recently when starting in the morning and selecting D there is a bit of a thump when engaging gear. It does not do this when warm. Not noticed this before. The ATF fluid was changed around 7k ago. Should I be concerned? Thanks

My car has developed a thump sort of noise. It appears to happen when I dab the gas pedal or when I release the gas. For example I'm moving around 10mph, I then press the gas pedal to speed up and I hear a thump. If I was then to come of the power as I take my foot of the gas pedal I hear it...

Any ideas how to easily add a bit more thump to the HK system in my C63 estate? I don't want to spend too much either. Not after max power style thump it's just lacking IMO. Maybe a trait of the estate due to speaker sizes. I currently have the 3D sound turned off as I find the upper...

Drive to reverse... 'Thump' Park to reverse... Perfect. Any thoughts? W124 230te Thanks!

Anyone had a thump/noise from centre console area on speed bumps? It's not a heavy knock, but noticeable non the less. It's under the car and not interior based. :doh:

Hi Folks, Have just taken possession of a 1999 Auto SLK 230K ( R170) with 54K warranted.The car has come straight out of a main dealer showroom as one of their p/ex`s and they are warranting the mileage as genuine. All is ok apart from the fact that there is a little "thump" when...

I have a serious thump from the rear nearside suspension. I have changed and checked loads of parts and it is still the same. The car is a 2002 c220CDI estate with self-levelling suspension. The bit I am unsure about how to test is the rear hydraulic strut (the thing that looks like shock...

Hi All Car in question is my beloved E320 CDi AvG. I tow a caravan but take care not to overload the towball (75kg MAX). A couple of years ago I noticed the suspension had gone hard, very crashy from the back. Following advice from this forum I noticed the fluid level in the reservoir had...

Hi there, I recently bought my first classic merc, a 1984 w123 200. It runs beautifully, and I am very happy that I took the plunge. There are, of course, a couple of issues with it, which I was hoping that somebody might be able to steer me on: 1> There seems to be a small, rhythmic...

On pulling away from cold in my 1996 C180 a thumping noise in time with tyre rotation occurs as though something is attached to the rear tyre, and you can also feel it through the seat. It only lasts about 30 seconds and is then completely smooth. This only happens from cold and I would have...

:doh: Just returned from work and my c180 Auto has started making a thump when changing up through the gears, more pronounced when changing from 2nd to 3rd, could it be the half shaft(s)? Thanks for any help/advice, has anyone had this problem and sorted it out themselves?

As we start filtering out the "lack of use" and niggly things one thing is that the gbox has a thumpy change (sometimes) under revs / load, its smooth as ever on part load - the fluid is getting changed but is this a "trait of the car" or a sign that it needs a box :eek: or a sign that it needs...

Hi, My pride and joy E230 Auto has only one problem. When I brake following a period of time on a straight road, the car seems to experience a thump like someone has bumped into my rear end. It seems to me as if the clutch orsomething isn't disengaging the drive on time. Is this a common...
