Reversal of software update for VW EA189 after the dieselgate scandal

Every other VW customer has problems after the software update following the dieselgate scandal

After the faulty software update at the authorized service, customers complain about quickly clogging EGR valves and DPF filters. To make matters worse, they have also observed a loss of power, louder engine operation, and even a very unpleasant smell from the exhaust.

The update aimed to reduce nitrogen oxide NOX emissions to legal requirements . After the update, there are fewer nitrogen oxides, but the engine emits more particulate matter, which clogs the DPF. The consumption of AdBlue significantly increases, and soot settles on the EGR valves, resulting in engine operation issues and a decrease in power.

We have a solution for this.

Based on the VIN number, we download the original software from the server, before the eco update. After updating the software in the ECU, we test the effects on a load dynamometer.

The cost of reverting the update depends on the car's production year:

  • Cars up to 2014 - from 1200 EUR
  • Cars after 2014 - from 1500 EUR

In addition to restoring the previous power, we can prepare stronger software by about 15-20%

The cost of reverting the update and preparing stronger software:

  • Cars up to 2014 - from 1500 EUR
  • Cars after 2014 - from 1800 EUR
