Here at RRP we have been super busy developing our own Gen 5 Haldex AWD Software upgrade and flashing tool  known as Haldex.Flash. By totally reworking the stock control strategy this allows us to improve power balance, cornering, and launch times. 

Our software upgrade is available for all Quattro and 4Motion MQB vehicles made from 2014-2024 with the module part number 0CQ 907 554 (X). 

Audi RS3 8V and TTRS 8S Now Available (Featuring all the improvements apart from power split as these models already have a 50-50 split)

In its stock form the Generation 5 Haldex unit will only send 30% of its power to the rear wheels under acceleration, although it does have the ability to send up to 50%. This is only achieved in certain situations such as wheelspin and for the most part leaves the car with a 70/30 front to rear power split.  

Our software allows a near perfect 50-50 power split between the front and rear wheels while under acceleration, this works wonders for overall performance in all forms of driving. 

This is all achieved while keeping factory tolerances safe within the Haldex system.  Vehicles with engine software benefit even more, the higher the power output the more prominent the front axle power is. This can lead to potential loss of traction, especially during launch conditions. 

Our upgrade is a must for improved handling, faster launches are simply an added benefit! 

• 50-50 Power split under acceleration for a sportier drive + traction 
• Improved response times allowing faster torque transfer 
• Torque split is not limited at higher speeds 
• Developed within factory tolerances of the Haldex system and built for daily driven vehicles and track use 
• 65% power increase to the rear 
• New launch control strategy allowing faster launch times
• Pump adaptions are carried out via our tool so no need for separate diagnostic tool!
• RS3-TTRS Supported 

 We have carried out extensive testing in all road driving conditions as well as motorsports. During drag racing we found an average 60ft launch improvement of 0.08/0.10 secs depending on conditions. Track work found cars where much more balanced during high speed cornering and corner exits. We even found use cases for cold weather conditions massively assisting ice and snow driving!

Pricing starts at £399 installed at our Headquarters based in the south of England. Installation can also be carried out one of our approved partners listed below. 

We also have a do it yourself tool available at the link below
