Lambda Sensors help

[Braz86]

As well as the faults on the main memory, I'm getting some in the shadow, 90-93 pre and post cat temps which a video I saw on changing the sensors said probably means they need changing, especially as they should be done every 100k miles.

The issue I'm having is that the listings on eBay have multiple OEM numbers despite there being three different sensors on real OEM.

Does it matter that they are listing each sensor under all three part numbers?

I recon it's the same sensors with different cable lengths the ebay ones probably assume you would be OK with a bit of cable dangling around? just speculating

BMW routinely change part numbers for what is essentially the same part. Maybe on change of their supplier. Or an upgrade which is backwards compatible.

@mrscalex @Mario it's more that three different parts are listed under one item, which makes me sceptical. Length appears to be the probe height, which is the same for bank 2 and both post-cats, but sensor 1 is shorter, so not sure everything would fit

I was assuming that L value was the cable length and the sensors themselves were the same item - i seem to remember reading people buying BOSCH 3 or 4 wire generic sensors can't remember which ones (cheaper but quality ones) and splicing their own wires with no problem so I recon you should be fine as long as you buy a quality no non counterfeit one if there's extra cable it should be no problem if you route it out of the way, but obviously better if you buy the right exact part.
