So my car just threw 30FF code, which I understand means there's a leak somewhere around the intercooler. I know the typical easy answer is check the charge pipe or diverter valves but I don't really know how to start. The only mods I have are a tune and dci. Got an oil change last Tuesday but I don't know how that would have caused it?

How does one find a leak? Diverter valves you can see from under the hood right? Put some soapy water around the connections? What about other likely places, do I need to be able to get under the car? Or is this a job I need to take to a shop for?

Thanks

could be as well a wastegate stuck open. if you are stock thats more likely the cause. Normally that is fixed with a new turbo... Do a leak test (spray smoke to see where the leak is) if its tight than its one of your turbos.

What tune do you have

How do you blow smoke?

funny thing - my wife told me her car was "down on power" and that it felt slow.

"i gotta push the gas real hard for the car to go" <--- which is surprising because i have the Cobb and the FMIC - thing will take off without even trying

anyways, i ran the car yesterday in the morning and noticed right away that the car was junk - car was NOT boosting

since i was on my way to my parents house i put it back in the garage and went out for the rest of the day.

last night i got home and drove the car again - same thing.

ran some codes via Cobb and threw this list:

P2FA3 - Cobb
P2AAF - freakin HPFP
P2D25 - ???
P29F3 - fuel pressure sensor
P30FF - boost pressure to leak from pressure line

looks like what i expected - leak somewhere. BUT, i don't necessarily believe it's located at the IC. it "could be", but it can be leaking anywhere, right !??

Jb4. But I just got it to happen on stock map too.

[jrsniper12453]

How does one build positive boost on a mt without actually driving? Is the only way to remove the intake and pressurize it from there with a compressor?

update: dealership called me and said "we replaced the Low Pressure Fuel Sensor"

[jrsniper12453]

So you didn't have a boost leak anywhere? Just a faulty sensor?

[kiteboy]

have you ever this fault code P30FF - boost pressure to leak from pressure line


what is issue about this ? not Pressure Fuel Sensor ?????

yep, just a faulty sensor.

drove the car back from the dealer last night, reflashed Cobb and my car was back to it's normal ass kicking self
