Hello everyone...
i'm new in this forum i look for your help.. i purchased a 2005 range rover.. after to days a message came up in the dash says; trans failsafe prog and vibration in the car while driving between 35 to 80 km/h in low speed with a noise.
i took the car to landrover workshop and they put the car on the diagnostic system and showed these faults:
1- Motor A and B off, A short circuit the ground (0x5230).
2- Motor A and B off, B short circuit the ground (0x5243).
3- Motor A and B open load (0x5238).
they told me that the transfer motor is the problem and the torque converter.
i searched google for similar problem and some people said that they changed all of these parts and the problem still in the car until they changed the battery. is it possible? cause i noticed when i start the car it keeps vibrating when i switch the lights..
i don't know what to do 2 weeks now since i have the car i'm so upset.
any help????

 

Please tell us more about the vibrations you notice???

You say it vibrates at a certain speed and it vibrates when you start it and turn the lights on????

 

there are two vibrations...
the first one when i start the car after one day in the parking garage after staring the car i switch the headlights on, a/C and the interior lights then the car starts vibrating, but when i switch everything off including the A/C the car warm up normally the vibration stops...
the second vibration comes while i'm driving it slowly between 30 to 80 km/h with noise like " whooooooo whooooooooooooo" but when i push the petrol the speed up the vibrating stops but the noise become louder sometimes and sometime it stops making any noise.
my cousin told me that it could be the battery cause these cars need alot of electricity the gear also,

 

Some of these RRs had recalled front differentials which produce vibrations and a whine. Your alternator might be on its way out if it vibrates when you turn your headlights and interior lights on. Most alternators normally make a bit of noise when you put on a heavy load, but if they are about to fail, they make more noise.

How many miles are on your RR and when was the last transmission flush done on it? They say the transmission is serviced "for life" but the fluid really does need to be changed regularly.
