E90 and 41e2 code

ppiotrek · 01-20-2017, 03:39 PM

Hi,

I get 41e2 error on my n47d20 but only when driving. There are no other errors. Any ideas what does it mean?

Cheers,
Peter

Yeah, I already found this. I did the EGR test in Rheingold without checking my vaccum pump and everything seems to be fine. However, I get the check light, usually after a long ride. I'm going to remove and clean my EGR this weekend, but I don't think it's going to help since valves in N47 don't get jammed...

Another news to my issue. I cleaned the valve and its socket. I don't get the check light anymore, however the error still appears in memory. Do you have any suggestions? Thanks.

I finally managed to resolve the problem. It appeared that the EGR connector was rusty therefore the valve didn't work properly. According to realoem I should buy: 12527507529 as a replacement, however it looks a bit different to what I have on my bimmer. I noticed the temperature sensor having similar socket, so I also bought this connector, this time MLK 12527804179 which was a good guess and works perfectly.
