Audi A4 B9 8W Hill Hold Hill Start Assist Retrofit Package Automatic
In stock

Description
Significantly upgrade your AUDI A4 B9 8W with the original hill start assist / hill hold.
After retrofitting this assistance system, your AUDI A4 B9 8W will automatically stop in one place WITHOUT having to keep the brake pedal permanently pressed.
A very convenient function, especially in traffic jams, in slow-moving traffic or at traffic lights, which is very easy to retrofit.
Here we provide you with the complete package for the installation of this additional equipment, often also called "Auto-Hold".
After briefly plugging it into the very easily accessible OBD diagnostic interface in the driver's footwell, the KECODI coding interface supplied here uses the innovative KECODI that is already preset for you to fully automatically activate the hill start assist / HillHold.
In addition, the so-called automatic handbrake is also activated.
When you turn off the engine, the handbrake is automatically applied and released again when you start driving, so you no longer have to press the handbrake button yourself.
In addition, during activation (= coding with the KECODI) you can select the release threshold of the hill start assist yourself in the levels "earlier", "normal" or "later".
"Earlier" means that starting off with the hill start assist works with less force on the accelerator pedal, so starting off is less jerky. The "Normal" level is set for a factory-installed hill start assist. "Later" means that you need to press the accelerator pedal a little harder when starting off your AUDI.
Scope of delivery:
- - 1x original AUDI A4 B9 8W HillHold button
- - 1x pre-assembled cable set

Please note the exclusion for vehicles from model year 2023 onwards with installed PR number NI8 (NI8 = Without UNECE CS (R155) and SU (R156) with SFD2-SG) or installed PR number NI7 (NI7 = With UNECE CS (R155) without SU (R156)).
Unfortunately, these models cannot be retrofitted or unlocked.
Please feel free to contact us to check before ordering.
Vehicles of the model year 2023 with installed PR number NI0 (NI0 = Without UNECE CS&SU) or vehicles of previous model years (e.g. 2022, 2021, etc., where this PR number does not yet exist) can still be retrofitted.
Product attributes:
The retrofitting of the original Hill Hold / Auto Hold / Hill Start Assist is possible on all AUDI A4 / S4 / RS4 B9 8W models of all years of manufacture (pre-facelift / facelift), all body styles (Avant, allroad, sedan) and all equipment variants with automatic transmission.
We are happy to offer you the retrofit package for A4 models with manual transmission (= "manual transmission").
Functional description:
You can stop on a slope WITHOUT USING THE BRAKE PEDAL without rolling backwards or forwards.
You can leave the automatic gearshift lever on D/S and take your foot off the brake - the vehicle will ALWAYS stay in one place without moving - by pressing the accelerator pedal your AUDI will start moving again immediately (even if the start/stop system is switched on).
With manual transmissions, it is sufficient to operate the clutch with the gear engaged OR, as with automatic models, not to operate any pedal at all.
You no longer need to apply the parking brake if you want to get out of the vehicle for a short time, etc.
When you park your AUDI you no longer need to use the handbrake - after pressing the start/stop button the engine switches off AND the parking brake is applied automatically (the handbrake is activated).
You can activate or deactivate the system at any time by pressing a button on the new switch.
A very comfortable special equipment for your AUDI A4.
