Hi, I apologise but I had to create another topic as I could not find anything similar to my issue. 
 

So the issue is that I have squeaking noise when car is loaded. Suspension dipped like 3cm not heavy load for sure. I will record video later and upload so everyone can see. 
 

So far as I can see it is coming from the middle where camber bolts are connecting lower toe control arms to subframe. I have to note that everything is new on the rear except shocks and springs. Also had exact same issue before with old subframe and old control arms upper and lower. Springs and shocks are in good condition and noise is not coming from them 100%. 
 

As I can see so far when car is loaded and suspension is lowered a bit, over bumps, uneven road surface, fast, slow it does not matter noise is there. When parked and I open boot and press down hard noise is there and its coming from middle of the subframe. All bolts are torqued. 
 

Please if anyone had experience with this issue let me know how did you resolved the issue. 
 

 

Forgot to mention what model it is.

Its Octavia 2011 2.0 TDI 103KW 

Squirt water on the various linkages and bushes one by one working from the bottom up and do your press down hard routine until you locate the source of the noise, alternatively give everything a good hosing first to see if that affects things before you retry when dry to pinpoint the source.

Have you checked the rear anti roll bar drop links as when one of them was faulty on my car it caused a squeaking noise.

 

Also recently I had a noisy n/s rear shock top mount that went bad and replacing it solved the problem, although it was difficult to identify as the noise was very subtle and difficult to pin point.

Hi, thanks for your suggestions I really appreciate this. So I made a video and you can see what I am talking about. Also the drop links are replaced and noise is still there. New subframe, new lower control arms, new upper control arms new bushings I mean everything except shocks and springs is replaced but they are in excellent condition. 

And this is from another angle 

Found the issue.
