Post intercooler temps high (FIXED)

I’m positive that my bypass valve is stuck so I’m not getting flow to the heat exchanger and once I’m too hot there’s no way to cool off. Is there a way to jump the bypass valve or disconnect it until I get to the dealer so she’s not running so hot

Kind of off topic but I wonder if we could install a larger heat exchanger up front and use ECM tuning to adjust pump flow to lower the air intake temps further then possible with the stock setup.

Definitely but when operating correctly we have awesome iats so not necessary yet.

The valve is not PWM controlled. It's a simple solenoid.

So what happens if we block the pwm to the pump and just mechanically bypass the bypass valve but leave it plugged in? Will we get the pump running in 100 percent flow mode with the full time flow through the heat exchanger?

If it's only a sillynoid, you should be able to just let it hang.

So are the relays in these cars proving to be more and more of a problem?

They are superseding the relays. The newest style is a 06106094AA. They look like a different manufacturer. From what I see, the nice thing about these FIAT/Alfa relays is that they have little resistors in them to send back resistance so the control modules can tell when they are not operating correctly. Because of this I wouldn't use a standard 4 pin relay as the car may not throw a code if the new relay fails.

Extremely helpful. Thank you for this.

So are these cars only throwing soft codes when these blow? No cel

Meaning we really should be code reading and/or checking post ic iats frequently?

LIN1 Code. Replace this relay! Don't burn up your turbo orings!

I've been looking to make a full post about this. I will soon.

Can I get to the relay from under the hood? I’m at work and it would be awesome to get a part number or something and run to the part store at lunch break and grab one.
