Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.
0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.
Leading evidence: 'Check under the seat' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check under the seat' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I know noises are hard to diagnose and my car has about 112km on it or around 70k miles. I noticed this morning for the first time when I stopped hard at a railway track like when you brake and stop abruptly. When the car transferred forward before settling again in the rear I had a thud. I tested this again dropping my little guy off at the baby sitters.
I would guess engine mounts but is there any way to check them before just replacing them?
Check under the seat. I had a weird thunk in a 997.1 and the mechanic found a golf ball rolling around under the passenger seat. Simple fix. Hope it's something like that...
Is it just one thud, or several for every stop? Engine mounts wouldn't make it behave like that, and your car would likely be shaking at idle if the mounts were bad. Are your back seats folded down? If not, try that while you look around the interior as Zeus says. If I had to guess any single component, it would be a ball joint or swaybar link.
I'm going to put it on the hoist and have a look over it. Then I should have a better idea. It seems to come from the passenger side seat area but its so hard to tell.
I ordered a set of motor mounts from my local parts runner for $100 each and I will change them as a preventative thing anyways with the mileage on the car and the exhaust sagging its a starting point.
It appears from looking at online pics my car has been lowered the previous owner was clueless so it could be a result of many things. Once I am in the air I will have a good idea.
