air box, air feed pipe going to the turbo, air feed from turbo to EGR, EGR hot pipe, EGR its self, all its ascociated sensors. then a clamp holding down coolant hoses, then another clamp holding a load of earths on held in by 2 bolts, then finally the two long bolts holding the starter in and the starter wires. the only sensors that i had to take out where the ones ascociated with all the low pressure air intake pipes. all of which i put back again and cleaned up. could try that earth bracket thing but i made sure i cleaned up the contact area where one of the wires earths onto it.
