How effective is this harness?

I've placed an eBay harness order, but I can't shake the feeling that there might be some subtle discrepancies.

This 2009 320d [E90 with N47 engine, model code PN32] is the vehicle in question.


This 2012 120d [E82 with N47 engine, model code UR32] gives us the harness that we need.

The original harness (the one that attaches to the main plastic box between the rocker cover and intake manifold) has the number 850720902, whereas the donor harness (also with the number 1251 850 7209) has the number 850720903. When it comes to both automobiles, RealOEM just gives you an 11-digit number without the 02 or 03 suffix and says it's the right part number.

Is anyone aware of any major distinction between the two?

A 2012 harness might not work because your vehicle's manifold, throttle valve, and perhaps DPF sensor configuration is changed from that year.

Instead of being located beside the alternator, yours, if my memory serves me well, has the manifold with the throttle body close to the oil filter.

I see what you mean about how close the throttle body is to the oil filter. This post was born out of my anxiety, but I've calmed down now that I have the donor vehicle's VIN: WBAUR32030VL28468. Based on my research on Realoem, it appears to be the same setup.

By 2012, the majority had the latest version of the N47, therefore it seems that the E82 never got it. It is evident that BMW did not update the previous 1 Series with the release of the F2X.

Then, that safety belt ought to work.
