I have a 2C78 engine check light, looks like the bank 2 O2 sensor is on it's way out and needs replacing.

I have been searching for OEM replacement Bosch parts and have found two sensor which are direct fit replacements with the correct 490mm cable length, Great, only one is significantly cheaper than the other and I'm now thinking it may not be a wise decision to go cheap as it may be an inferior part.

The sensors in question are Bosch 0 258 010 414 the cheaper of the two, the other a Bosch 0 258 006 796. Item links below

0 258 006 796

Both carry a 2 year warranty, both have identical cable length, so what the difference other than cost?

The fronts are interchangeable. You can buy 2 of the cheaper front Bosch sensors, you'll just have to coil up the extra length on the one, and not mix them up. One of the threads on here if you search details what the Bosch part number is.
