Hi everyone,

I've recently acquired an X5 (2007, 3.0 SE diesel) and have an issue I was wondering if you would be able to help with. The car came with the known quacking noise, and I have replaced the pressure converter and the EGR valve at the same time. This has resolved that issue, but now I'm receiving a warning stating 'increased emissions'. Has anyone experienced this before? I've come to the end of my limited youtube-inspired mechanical knowledge and was wondering if anyone could help before I part with lots more ££££ to let someone (BMW?) take a look.

I'm South West based if that changes anything!

Thanks all,

Sam

Morning Sam

Emissions out of whack can be upset by many things from a clogged fuel filter or air leak to worn injectors causing over fueling are just a few. Changing parts is a very expensive way of fixing the issue as sods law dictates you will change a whole bunch of stuff unnecessarily. 

You do need the diagnostic codes read, that will give you a clearer picture on what and where the issue is. I use BMW 1.4.0 loaded on an old lap top not expensive (about £15) and gets the job done there are many others available and the ability to do a "home" code read is invaluable. Obviously a BMW Dealer can do it but £££ as can a good BMW specialist (there is a Register of BMW Specialists just Google) less ££ and of course a good Independent garage again less ££ or maybe a member on here who is local to you has the kit, worth asking.

Also check www.newtis.info it is a BMW Technical information site same information that BMW use for repair/replacement information. www.realoem.com is another useful site this is a BMW online parts list just put the last 7 digits of your car in the search box it will bring up your model, it has useful small exploded drawings that will help with were parts fit.

Not an answer but I hope helpful

Hi Dave, just wanted to respond and say thanks for your reply. I think the pressure converter that was replaced at the same time as the EGR valve is a bit of a wonky party. I also had the codes read and it turns out one of my glow plugs is dying/dead, so need to replace that as well.

Thanks again,

Sam

Had these codes thrown up and loss of power. E70 X5 2010. Any ideas?
