My td5 is Remapped by previous owner. I noticed the vac pipes for egr are simply disconnected from egr I.e plunger never opens. One vac pipe goes to butterfly in intake, other to egr valve. Both cable ties out the way. I will order a propper blanking kit payday but I’m sure this is another bodge. I’ve just removed egr and cleaned up. Valve is operating by finger so not seized. Should I reconnect the vac hoses?!
