I have a long list of problems with my mk 4 golf. It is the GT TDI 115 3dr version.
I have 18 inch OZ wheels and the car is lowered something ridiculous to the stage I cant have more than 2 passengers in my car without the car arching and it is very uncomfortable. It is lowered with coilovers and I dont know the make of them. I want to make the car back to the standard version suspension, Is this an expensive job? Anyone know where a good place to get second hand parts would be?
Next problem

, My traction control and ABS light do not come on when I start the car, traction control and ABS is also not working. Any ideas on what has happened here?

Last one, The handbrake light flashes and there is 3 beep's just before the light starts flashing. I checked the brake fluid and it is fine, I am stumped as to what to do. I am saving up some money and will drop the car into my local VW garage but I would like to be armed with knowledge before I go.
Thanks to anyone that read all of that, your help would be greatly appreciated
