Pump starts then stops within a second. MKVI GTI - HFS-4

Bump! Any help please? I don't have the amber LED on my gauge no more..

[Richard L]

I am not sure what the problem is, please explain again in more details.

[maskari_gti]

I think that I need to recalibrate my failsafe. Could you please walk me through to accomplish that Richard? I keep getting restricted boost, low MAF readings and not good Intake Air Temps due to having limited power. That's my assumption.

I adjusted the Thres and I believe that failsafe isn't operational no more.

[Richard L]

which way did you adjust the THRES? If you lower the THRES you need to lower the WL.

I lowerd Thres but I still feel that failsafe isn't 100% as it was.

How can I set a min and max boost? Before, when I used to switch the controller off (FS activates), I used to be able to get 7-8PSI. Now, I got no boost at all. The boost gauge shows 0PSI.

[Richard L]

The system has no control over the boost pressure after failsafe activation. All it does is disconnect the BCV from the ECU.

Under this condition, the boost pressure will be your wastegate pressure.

Hello again,

My car seems to run almost perfectly now. Only thing I notice is lack of cooling affect I used to get in the past. It's a maximum of 10 Degrees Celsius IAT drop. I could't find the issue, frustrated.

can you check the spray pattern of the jet.

Sorry I didn't quite understand what you mean.

If the jet is partially clogged, it will show up on a spray pattern test.
