    No power in reverse at morning startup

    This has only occurred since last regular service 2 weeks ago but suspect it’s just coincidental. At first startup in morning when reversing out of shed the vehicle has very little power. Even if I put accelerator right down there is only a slow crawl backwards. It’s like the ECU is cutting power when in reverse at first startup. Going into Drive, everything is normal. After driving only a few hundred metres if I stop and go into reverse everything is normal again. I have had all fluids replaced every 75,000km including auto with a service. This has been done twice since new. Last auto service was about 35,000km ago. Seeing indie tomorrow to get his suggestion. What are your thoughts on where to look. Thanks.

    Spoke to indie’s apprentice today 3 or 4th year who did service two weeks back. He said he checked auto transmission oil as part of service. Fluid level full and nothing abnormal about oil. He was a a bit of a loss as to what might be cause.

    Check the steering angle, if I'm backing up with the wheels turned its the same

    EGR sticking open after start up tests? I’d have expected codes for that though.

    Try doing the exact same manoeuvre with DSC off. Just like in sand it may be seeing some slip or irregularity and killing the power. You’ll know for sure in this test.

    Saw indie today. Seeing him early next week. Thanks for all suggestions, hopefully will get a few more. He is going to check for codes. He doesn't reckon it would be steering angle or brake switch as it would happen in Drive as well, not just reverse. Shouldn't be EGR, the ECU was flashed 18 months ago and they were shut off. Will try the DSC, interesting idea. Car didn't do it this morning so will keep on searching. Thanks all so far.

    Did you attempt to “drive through the handbrake” or had you disengaged manually?

    My shed and driveway is totally flat. I don't use the handbrake at all when parked at home. My thought here is the less I use the EPB the fewer activations so hopefully that will help with longevity. So handbrake was not engaged any time when this occurred.
