Loud sound when i start cold car (coldstart)
 

Hello
I'm writing on the group because I have a problem.
after starting a cold car, the car is very loud and sometimes it is rpmkick. the problem stops after about 1 minute when the revs drop to 900 and it works perfectly when it warms up and the idle speed will be at the level of 650. I noticed that when the engine is running at this highrevs and i change my shift to D - at gearshift. I hear kick from front central panel in cabin.
I know that this car is a special care car but im really irritated when i start car and it's so loud.

I change oil in engine after 4000mile and use 0w30 millers nt+ , only this one i use 0w30 amsoil signature series becouse milletd will be unavalible in shop. Now im bought millers and wanna chsnge this amsoil becouse i think my car better runing on millers than amsoil.

Anyone help how to delete this issue or maybe this is normal in this car? Maybe someone send me video how your engine run after night then I could compare my and your coldstart.
When all liquids in car get good temperature then it is so quiet that people ask if it's electric :cry:

Did you recently get it tuned? Installed Catback?

Oil wouldn't really have anything to do with cold starts, as long as your temperatures look good according to your driving style and scenarios, it doesn't matter what brand you use. It also all depends on outside temperatures.

If you recently installed a catback system, depending on which one it is, the packing might be wearing out causing louder starts.

Regarding the kick, have you done proper maintenance on the transmission? Like change the oil?
Do you drive in manual mode often and abuse the transmission?

Hey thanks for your answer.
Im have oem exhaust and car never see tuner. All what i change is kn air lifter.
I change dynamic oil in At max 1000mil earlier. Im use this car only for daily driving and sometimes use sportmode and manual on AT. But always im wait for good temperature. AT runs perfectly and does not drag gears etc.

Maybe a problem with how it came out in english, but what do you mean by RPM kick? Do you mean the revs go up and down?

I'm sure you're aware, cold start cars always start at a higher RPM (1000-2000 RPM) and then drop down after warmup or when you put the car into gear.

Since you asked, here's a video of my engine after cold start. It is always a pretty loud start.

This seems like normal mechanical operation. At at high revs, it probably engages the torque converter very hard when you shift it back into Drive from manual mode. You probably shouldn't be shifting from M back to D when your revs are high!

Sounds normal to me like a damn tractor
