4x4 AWD, DSC and ABS malfunction
 

2010 bmw 535i xdrive with 130,000. I try to be a DIYer and had to replace the right side front axle and gear oil about 3 weeks ago. Everything was good for 3 weeks and now I'm getting a 4x4 AWD, DSC and and ABS malfunction warning along with codes 5DEC Clutch Gear Box and 5E4D Wheel Speed Sensor Front Right. I have cleaned both front ABS sensors with no luck.

When I back out of my driveway (2 car lengths) the ABS feels and sounds like its engaging when I apply the brakes. Then I put it in drive and get 4X4 AWD, DSC, and ABS malfunction almost instantly. After I get the malfunction message the car runs fine. I am going to change the front right ABS sensor. Has anyone else had similar issues and what was your fix?

When you replaced the right side half shaft, what part did you use and where did you get it?

I bought an axel from Napa Auto Parts. I believe it is their brand.
Constant Velocity (CV) Driveshaft - Front Right - NewPart #: NCV 941125
Line: NAPA Premium CV Shafts

I will say that I've read a lot of threads where people used non-BMW or non-OEM parts for driveshafts or axle shafts and just had problem after problem. The OE supplier was GKN if I recall correctly. For all the ones I've seen I would not use anything by BMW or GKN.

Update. After replacing the front axle I was getting the 4x4 AWD, DSC and and ABS malfunction warning. I ended up getting ABS sensors from carparts.com and replaced the right side and have not had a single issue with the car since. I know a lot of people say to use BMW OEM replacement parts but so far so good. NAPA CV axle front right $145, carparts.com (2) ABS sensors $60 and my time (priceless).
