endlich - GFB Schubumluftventil

Hier noch ein Statement von GFB zu den Fehlercodes:

"As far as the soft fault codes go, we know this is not a problem, they are not on the dash and no one would know about them if they didn’t have the scanning software. We have spoken with both Audi dealers and VW dealers here and they are not worried about these codes. We have done a lot of work with this, please find below Brett’s findings;

P2261 is a “soft” code that can appear when using the DV+ with both springs installed. The majority of cars will not see this code, but whether or not it appears depends a lot on the individual car and the current modifications. P2261 does not illuminate the check engine light, nor does it have any flow-on effects within the ECU, and therefore is quite harmless. This code is simply a result of the ECU detecting a change in the behaviour of the diverter valve (N249 valve), and logging an error code that prompts a service technician to inspect the diverter valve.

The DV+ is designed to operate differently so that throttle response and boost recovery on gearshift are improved, and in the cases where the P2261 error code appears, that’s exactly what the ECU is detecting. Part of the reason for replacing the factory diverter is so that it offers a performance benefit, and to do this, it MUST operate differently than the valve it replaces or there would be no point replacing it.
Although the P2261 code is harmless, it is possible to install the DV+ without the main spring (the short, larger diameter one behind the brass piston) so that it operates the same way as the factory diverter. This should prevent the error code, but it also means throttle response and boost recovery are the same as with the factory diverter. You do still get the benefit of improved boost holding though."
