Hello everyone, I recently purchased a used LR3 off auction and the car is throwing up multiple codes such as: HDC, Transmission, Air Suspension. On top of that my E-Brake does not work,tail lights dont either, and when I start to drive the car, the airbags deflate.

So far, I have replaced all the smaller fuses in the engine compartment as well as behind the glove box. On top of that I have replaced the stop light sensor as well. But after doing a battery connector reset, the same lights pop up. Im thinking that the ECU might be still reading off the old codes but have no sure way of telling. The previous owner said he had been towing something when all those lights popped up. Im looking for any sort of help, im quite fluent with a tool and know my way around a car but am pretty new to the British cars.

 

You need a Gap IID tool to get the real story of what the LR3 is trying to tell you.

Change those and be sure to use quality bulbs that don't allow mis-orientation of the filaments. They should be vertical. Did you mean brake "switch" you changed? If so....good. how is the battery?

 

Check the battery - voltage must be 12v or above and connection tight. If not, charge it up. Also check earth connections in the engine dept. Check voltage at battery after starting it should be 14+ volts if alternator is good.
As already said - replace rear lamp bulbs as these are known problems.
