My DISCO TD5 has started giving less power when taking off till after two to three hundred metres of desperate pressing on the accelerator, of course with thick dark smoke from the exhaust and less acceleration
. The same also happens when going up slopes in mid gears but it never used to happen before. There is an obvious leak on the Pressure Regulator and that needs to be replaced. My garage also suggest the EGR must be replaced. Is this likely to get rid of the problem or could it be something worse? I do not want to hear about injectors having to be replaced
