SCR Delivery Module

Aevintiri · 04-10-2018, 11:07 AM

I need some help guys! I'm currently trying to diagnose and repair my SCR active tank leak. I use ISTA very frequently and have searched it very thoroughly and still cannot find any procedures on the particular part of the tank.

I have all of the procedures off ISTA for removing the entire tank but I just need help with taking apart the module on the bottom where the connections plug in on the bottom. The ISTA procedures slightly refer to it as the delivery unit. I will attach some pictures.

I have checked this whole tank and can't find any cracks or holes in the tank it self, so I think it is just in the delivery unit and there are screws, so it has to come apart so I can look in side and see where the problem is. Thanks guys!

BMW says: "tank flange unit is not individually replaceable" or something like that. Have you read the SCR 2 for US document? It has some pics/etc starting around p.57. Follow the links here to the document: http://f30.bimmerpost.com/forums/sho....php?t=1393981

Not sure if it's going to help but it's all I've got.
