Hi guys,
So, I've read many forums on many sites (including this one), but I can't seem to see a straightforward answer to this issue: EGR delete. I have a 2009 320D with the N47D20C engine and 130,000 miles on the clock. She runs like the day I bought her 5-6 years ago (with just over 60,000 miles on the clock), never had any major issues - the crankshaft pulley broke. It basically still has everything 'factory'.
So, the time has come and I would like to make some 'upgrades'. Fortunately, I live in country where removing the EGR, DPF, and cat is 'okay-ish'. However, I've read in some forums that removing the EGR could cause the engine to overheat - now, I understand the basic mechanics behind the EGR, how it works and what it does, and therefore I can't understand why some people claim it could cause the engine to overheat? Is it because combustion temperatures will be higher? or does it have something to do with the coolant ports that supply coolant to the EGR? Is there any way to negate this?
I found a kit online that allows you to completely remove the EGR, plug the coolant ports, and blank the exhaust and intake ports. I'm also going to remove the DPR and replace it with a downpipe, and remove the potentially problematic swirl flaps in the intake manifold. I've also got a larger Wager Tuning intercooler on the way, and then I'm going to get it remapped. Local tuning companies claim they can push it up to 240 hp and 440 nm (from the stock 177 hp and 350 nm). They say they can simply disable the EGR 'programmatically' and there is no need to physically remove it.
But the question remains: would removing/disabling the EGR cause any major issues like cooling or something else?
Thanks in advance!
