@davidke20 man I just realized Renautech soldered my TDC sensor too

and the startup issue is still happening even if its less frequent
Also I did run into what you did too, where my RPM went up to 2.5k++ even when on neutral. This happens mostly when cold start aka morning start.
Also my reverse sensor got attitude already too lol got noone behind still got sound. But it works la still. Can live with it.
I also have this issue when I hard accelerate or hard brake, there is a very loud noise on the RFW like it is being hit by a hammer. Renautech tried to troubleshoot it last time but to no avail. :/
Got crank but hard to start up could be throttle issue jor. If solder the TDC sensor ady shouldn't be problem. TDC kinda unable to start, you can't start at all. Not you crank longer the car can start.
To answer your 2nd question 2.5krpm, that could be the throttlebody mispositioned itself. Get it service, if not mistaken TB cleaning servis Renotek caj RM20 nia. If after servis still kenot settle, Renotek will bring out their spare unit to test on your car to see whether TB servo rosak. Recond TB repalcement cost RM250. If replacement TB testing unsuccess, you only have 1 problem. Intake manifold/vacuum leaking. Whole intake system need to take down and servis. Car need to stay in hospital for atleast 1 full working day.
I have rerouted my whole reverse alert system with new wiring. My own magician did it for me.
As for the brake/pickup noise from undercarriage, it should be lower arm bushing/absorber mounting/spring mounting worn off. I have that sound, but not severe like what you've described being hit by a hammer so not planning to repair YET.
