Nope, it's unscrewed, the car goes into park when I turn the engine off, but not when I double tap the lever into neutral.

When you using dct shifter with 8hp Turbo Lamik then TCU add P function when you gady double click N position

This doesn't seem to work on my car. The light on the shifter changes, but the gearbox is still in neutral as the car rolls down my driveway.

How would I check this?

I don't think it's the paddles as the car shifts fine when driving.

Lately, when I come to a halt in traffic, or at lights, or at a junction my car will sometimes suddenly go from 1st to N,

It's only started doing it recently, and it's not always, just occasionally, but I have no idea why.

Any suggestions please?

These guys have made a manual override for the DCT boxes, and if you read the comments they are working on a manual override for the 8HP boxes, which should be available very soon.

So for anyone interested it might be worth keeping an eye out to see ...

Hi.

I'm about to install and 8HP70 into a car (not a BMW) that has the BMW Drivelogic button installed (car was running an E9x DCT).

Instead of using the rotary knob in the Turbolamik kit to change the driving mode could I use the existing drivelogic button instead?

Hi.

I'm about to install and 8HP70 into a car (not a BMW) running a Syvecs S6+ ECU linked to a JT Innovations Toucan touchscreen.

Instead of using the little green screen that's in the Turbolamik kit could all the info be displayed on the Toucan instead?

Sorry, what do you mean by "P throws a Tilt Double into N"?
