Chinese are going to take over the automobile industry for sure. Tesla who was considered ground braking is shying away from the promised small EV and moving to Taxi cars as the competition is too strong. Then comes Chery with this small EV SUV. Looks like a Mini G Class / Jimny but is fully electric.· 4 replies

Interior Specialists? Every time I go over some bumps my seats squeak quite loudly and there is a massive rattle of a nail undone coming from inside the dashboard, anybody got any suggestions I could go to? My usual mechanic just said "turn the radio up"· 2 replies

I was watching a Yangwang U8 struggling to make it up a muddy hill on Youtube. I was wondering why cant an EV be more capable off road than an ICE vehicle. Given the fact that this behemoth has 4 individual motor on each wheel it should be able to direct power to the wheel that has more grip and stop power to the slipping wheel. Cant be rocket science right?· 3 replies

I woke up one day and I now want to buy a W140. The brain works in mysterious ways. It definitely doesn't understand the concept of money since I am nowhere near affording one.· 2 replies

Question
MiraOwner
Guys,
i have been having a serious issue with the car and couldn't resolve it even after spending the whole day at the garage yesterday. this is regarding one of the previous topics that i posted as well (Motor mounts)
There are serious vibrations in the car when idling and at low speeds with heavier loads (AC on and multiple passengers on-board).
The garage guys are 'trial and error' mechanics. initially after running on the road with the 'chief' mechanic he said the car is sluggish and lets do a complete fuel system clean up to see if it would reduce the vibration so they went on and did the following.
* switched to new spark plugs
* new filters on the fuel nozzles (the tiny ones with the mesh, don't know the technical term)
* fuel tank was removed and the in-tank fuel filter mechanism and fuel pump were cleaned up with thinner.
* fuel rails cleaned up.
after this the car became more responsive yet the problem remained.
the gearbox mount was the next one to be changed as the mount was pretty badly damaged (refer my previous post)
but as per the mechanics the other two mounts are not that bad and didn't need replacement
second trial on the road revealed that the vibration increased a little after changing the gearbox mount.
Later the mechanics were claiming that it could be an issue with the steering mechanism and the vibration is travelling from the engine through the steering mechanism to the body and the dash.
at this point i was fed up and having spent 7 hours at the garage i thought of calling it a day.
now with my observations. i feel that the vibrations are originating from the gearbox.
i did the following and this is what i found out.
When holding on to the brake and engaging D the vibration goes up to a noticeable level, when engaging R (reverse) vibration is twice as much (as if the whole car is going to fall apart), and when in N the car is as quite as a mouse.
Experts! need your input! I'm totally lost.
