• My mate mentioned a website that helps you compare quality of non-oem vs oem parts by manufacturer. Anyone have any idea what it is?

    I need to replace the front left speed sensor on the e46 according to my scanner, but I have no idea which make to buy. Going from the names I know it's between Hitatchi, Bosch and Febi Bilstein - with the latter being twice the price of the former, so I'd be keen to know if there was a resource I could reference in future because there's always about 50 different manufacturers of non-OEM parts and I have no idea what to go for (other than sticking to the handful of brands I know), and apparently even the bigger names like Febi Bilstein are only good for certain things, and they pretty much just slap their names on other parts despite not actually being made by them.

    Also, does anyone know of any helpful guides for using a scanner (Foxwell NT680), I've had a quick play and found out the info I was after (which corner was generating the ABS fault), but it seems there are other faults present but I'm struggling to make much sense of them beyond doing a quick google. @Fixedwheelnut (sorry to be tagging you, again(!)).

  • My attitude is why risk your life and others with cheap parts, Febi are good as are genuine Bosch, a lot of fakes out there so always find a reputable supplier. I often use Autodoc, wait a while for delivery from Germany but good value & so far no quality issues.

    Foxwell scanners you can read the codes but also useful is status requests were you can pull up live data, especially useful for temp sensors and speed sensors as some will not show a fault because they provide a signal but it can be a wrong signal.

    What are the other faults you have?

  • Aye I’d never buy a mega cheap one, went Bosch in the end - happy middle ground price and a familiar name.

    Will need to have another go with the scanner and make a proper list of what comes up - some things I couldn’t make head or tails of, parking sensor (classic), something about the coils and coil pack relay, maybe some others too. It was all done hastily just to see if it worked, need to have a proper sit down with it and note all the codes.

    I’d have thought a serious error with the coils would give me an engine light or similar. Something to investigate (or ignore until it becomes more serious).

  • Ended up with a fake Gates thermostat and housing for a merc once from a local parts factor, spotted it once I tried to fit it. Bit of internet hunting and turns out they are fake parts in genuine boxes, mostly in the USA but this one was in Scotland. Took it back to them and they didn't believe me until they really looked at the part. Pulled another from stock and sure enough all of them were the fakes. They genuinely had no idea, and were quite embarrassed.
