AGR- 325d n57 tuning. Question in english....

    Hello.
    Sorry, my german is very bad. I hope it is ok that I ask a question in english....


    I have a 325d year 2011 (n57 - 204hp) that I am going to chip-tune / remap.
    My tuner say I can choose if I want to delete the AGR (software) or keep it functioning. What should I do?


    If I want to delete the AGR, is it OK to do it only with software, or should I do it also with hardware (block plates)?
    Is there any drawbacks with deleting the AGR? Will it take much longer time to get heat in the car/engine on really cold days?


    Thank you/ Danke...
    :)

    Thank you for your answer!


    I read on www.e90post.com, that on the n57 335d (286hp) you need to block the AGR (hardware) in addition to deleting AGR with software.
    If not, you risk to crack the AGR cooler line, then water can come into the engine.
    I do not know if this is the same on my n57 325d??
