The switch with a lot glue coverd on the case, we could see the glue obviously from outside.Now we improved on it, no glue on the switch, looks better.I struggled for hours just the other day on a 2008 M5 (USA/SMG).

So have do some improve with the switch with just 2 files. Since it is hard to make improvements with the function, we do some small change with the details in the swicth.Īs some customers feedbcak the switch with 4 files, but it just need 2 files. In general you can choose the chip you are prefer, they are both could works well with its function.

USB cable connect way: some usb cable soldered to board then glued, some are with a small white outlet, most buyer prefer the kind which with the outlet, it display a degree of visual refinement.įTDI Chip: From the board we could see, most of the chip are similiar, the FT232RL chip and FT232RQ chip has differnt size. Covers with a lot of glue for switch, from the white transparent cover, we could see the glue from outside. Switch: Most of the switch kind BMW inpa are same switch, the switch with 4 files. The common colors of the BMW inpa is white transparent and blue, there are also some customized color such as red,and so on. In the past, we normally insist on the FT232RL, but now in fact FT232RQ more familar in market, why? Because the FT232RL chip really hard to get from the original United Kingdom, not only because its price always changing from higher to higher.ĭifferences between the FT232RL version and FT232RQ chip version for bmw inpa k+Dcan with switch from hardware visual angle：Ĭase:most of the case of are same, there are no obvious difference between them, may be the color of the screw is diferent, some with sliver screw, some with black screw. There are two versions mainly from the different chips, both are FTDI chip, but one FT232RL and one FT232RQ.(we are talking about the main streams, not including those very tiny minority versions-may have the very good quality kind for OEM version, may have very poor quality kind just to save production-cost.) Now in market for obd diagnostic cable, you would find BMW INPA K+Dcan with switch everywhere, yes, very hot and very popular.
