Auto supply giant Bosch is being investigated for its part in the widespread emissions cheating scandal that has engulfed Volkswagen, Bloomberg reported (via Automotive News).

Prosecutors in Stuttgart say that they’ve contacted the company, which supplied Volkswagen with engine control modules that helped the cars illegally pass emissions tests, about their role in engineering the illegal devices.

A spokeswoman for Bosch said it would comply with requests from authorities.

In September, German newspaper Bild am Sonntag reported that Bosch may have warned Volkswagen in 2007 that the software it supplied would be illegal to use on the road. A company spokesman said that it supplied parts to Volkswagen, but was not responsible for how engineers at the automaker used those parts.

“In the wake of what was reported about the emissions case at Volkswagen, we concluded that someone must have produced the software,” Claudia Krauth, a spokeswoman for prosecutors in Stuttgart, told Bloomberg. “It was obvious which company came into question.”

    Yep it rolls down hill.

    The story is unclear (or, at least, does not back up the headline): Is Bosch under investigation (as in, possible charges being considered), or have they merely been contacted as part of the investigation (which would be totally expected, even if they were not under suspicion.)

    BTW, the “via Automotive News” link that might clear this up doesn’t work; it leads to another TTAC story.

    It is not clear, but they may be under investigation for supplying the software. The way I understood it they supplied prototype code which VW took and went to town with it. Then, at some point they may have been asked to embed this code to all the ECMs. I would be very surprised if Bosch did warn VW but did not bother to determine their possible legal exposure.

    Well it really depends on how Bosch supplied this stuff. If they gave them a bunch of firmware files including a “test file” for “offroad use” or some nonsense and then VW flashed the cheating firmware onto all the ECUs themselves then I suppose Bosch might come out clean by saying that they had no control over what VW did with the firmware. But I’m pretty sure that Bosch is also the producer of the ECUs, so if they produced and shipped several million ECUs with the cheater firmware already on there it’d be pretty hard for them to claim that they didn’t know that VW used this illegal firmware in production vehicles. You don’t ship over millions of ECUs for protoype testing.

      Let’s me clear up what I meant. Bosch gave them prototype code, VW used that to develop the full PCM suite, then gave it back to Bosch to embed into all production ECUs that VW was buying from them. Bosch knew, but I would imagine that even after sending VW a warning letter their legal team also made a determination that their contract isolated them from any liability. But I agree, this looks like knowingly abetting someone to circumvent laws. It would be akin to supplying thousands of microwave oven doors with no radiation shield to an appliance maker.

      I find it hard to believe that such decisions were made in the absence of the full and often overbearing presence from the company’s internal legal teams. That would be a huge risk to Bosch even if the trade-off was first dibs in a nascent market.

      In all the product development I’ve worked in it took forever and a day to hash out all legal issues and quantify legal risk. Did VW and Bosch do none of it, or were they incredibly inept at it?

    I wonder how many secrets Bosch is “withholding” related to other manufacturers.

    Bosch is a huge supplier to the auto industry.

    As a former cog in the great machine. I assure you SW, calibrations, features, configurations, etc… don’t make it to “serial production” unknowingly to Bosch.

    Bigger news is that the European Parliament voted against the proposal, that countries like Germany and the UK insisted on, to allow a 110% (!) deviation over the legal limit. And… there’s likely to come a sort of parliamentary investigation how emission testing and approvals take place.
