I see, does it switch off (or whatever it does) when the engine gets warm so you're only adding cold air?
Reason for asking is I saw someone selling some device on Ebay that claimed to bypass the EGR and improve the performance of the turbo. If the EGR only worked when engine was cold there would seem little point by passing it given the time the engine takes to warm up.
Cheers
Don't buy **** off eBay, just remove the hot gas feed pipe from EGR valve two 8 mm bolts (13 mm spanner) and block it off with a coin. Bolt back up job done.
