Bought an A4 with adblue delete so it seems, no codes or anything on dash however when scanned shows a code “lost communication to reductant control module”. had it scanned at a specialist to find the cause, the adblue was unplugged so they plugged it back in and it came up with engine light, multiple adblue codes. So unplugged it again and back to no errors except the lost communication code. They said looks like it’s been coded out as there’s no lights on dash when unplugged, is it normal to have the lost communication error code with the adblue delete & unplugged? also start/stop doesn’t work but I believe this is normal with an adblue delete? any information people can provide with this will be appreciated

Recently bought an a4 avant, drives fine and no lights on dash. However start/stop doesn’t work and I’ve noticed when scanning it I get one code U010E lost communications with reductant control module, just wondering if this is normal with an adblue coded out?

Hi guys, so I’ve recently bought an A4 2.0 190 Diesel, no lights on dash or anything but just scanned the car to see if it had any codes. it’s come up with the error lost communication to reductant control module, hear this could be an adblue problem? But I’ve got nothing on the dash to say any problems.
