Thread: Fuel Pressure Challenge 2010 D4 2.7

Maybe there was a firmware update at some point - with the brakes touched on (enough to turn the lights on) the accelerator is completely ignored in my 3.0 D4. Were you in low range? maybe that changes things (I haven't tried), or possibly the trailer made a difference

The firmware was kept up to date and low range would have been used. The trailer had LED globes but no load resistors - the trailer indicator didn't work with that trailer.
I recall that there was a firmware update quite early to address the issue. I used a Faultmate to keep firmware up to date, downloading the latest versions from the Blackbox site.
