What are you talking about? Assembly tube? Acceleration video?

WTF

 

Looks like poster is from the middle east, assembly tube is probably some funny word the illiterate dealers here use for some part

 

I got the same impression. It's something that we probably refer to differently. OP, can you clarify exactly what you are referring to? Perhaps a photo of the part you are talking about might help...

 

 

Ok, better. Hard to tell from the PIC but that looks like your fuel lines and or brakes lines to the left. Not too familiar with the underside of the G, but the "breather hose" you are referring to, what is it for - transmission? radiator reservoir? fuel tank?

Again not familiar with the G's plumbing, but mechanically could help you out knowing what the hose is from.

BTW (by the way) those tubes look melted, not crushed.

 

^ I agree with everything he's said. Can't tell for sure what it is by the pic, but they're definitely not crushed.

 

those lines from fuel tank to the engine .

 

You may try running an OBD-II diagnostic to see what code is displayed. That might give you an idea why the car is running the way that it is which let's you know what's needed to fix it. If you don't have a code reader or want to buy one, many auto parts stores will read it for you or allow you to use the reader.

BTW, where are you located?

 

i checked my car before by OBD-II but there is no any code !!

i think the breather tube affected on acceleration.

 

Then I think that your next move should be to return to your dealership and tell them that the damage that they caused is still present on your car and that you think it is affecting how it runs. They should have the responsibility to repair it as it was before if they caused the damage. Show them what the problem is and tell them that it wasn't present before the damage they caused. Have them order the part necessary to repair it.

 

I agree with black betty above as that is the proper way to go about things. Get the part replaced properly.

However, depending how close you are to your dealer or how long it is until you can get them to fix it (or if the screw you over and don't fix it), there is a temporary diagnostic fix to see if that is what's causing the car to run the way it is.

First I would take plenty of clear pictures for documentation for the dealer. Next, cut out those sections of hose and go to your local auto part store and buy an equal length of rubber hose with couplings and some band clamps. Replace the section and drive the car. Obviously if it runs fine, then that is the problem. If not, still get the lines replaced properly.


...I still wonder what could have caused such damage at a dealer. It definitely looks melted, and not crushed. Unless they were welding or using a torch to loosen something up, there is no other reason how this could have happened.
