My car is throwing a p0299, p2178, p2187 which is under boost, vacuum leak, and exhaust leak. The dealership think it's do to aftermarket part. Any other ideas?

 

What aftermarket parts?

 

See if the vac line going to your cold side pipe has broken off at the nipple. Bypass vac tank to test for leaky tank.

 

Upper Charge pipe, Cold air intake and Hahn Down pipe and cat back exhauts

 

where is the vac tank on the coldside?

 

Sorry. That was two separate things. Look at your cold side pipe. Locate the TMAP sensor. There is a hose right next to that sensor that goes to a solenoid on top of the intake manifold. Sometimes, the barb on the pipe that the hose attaches to, breaks off. Make sure that is not broken.

I don't have access to my computer right now, so I can't show you pics of the vac tank. It's under the intake manifold. Sometimes they leak and need to be bypassed.

Also, check the BPV diaphragm for tears. When I get back home, later today, I'll post pics of all of this stuff.

 

Its not the vac tank I just bypassed it today how to I tell of map sensor is bad?

 

This isn't really a code associated with a bad TMAP sensor. You can sometimes tell they are bad when you register boost while revving in neutral.

The hose is still connected to your coldside pipe then? It's the hose that has the green clamp on it, in the pic.



If that tube is still connected, I would definitely check the BPV diaphragm for a tear. It is behind the tan cover on your turbo. It's kind of hard to get to, but not too bad.

 

Could a untuned car cause a code because I have the Hahn cai with no maf tune? Just curious

 

Not likely I had that and it didnt

 

well im running out of ideas

 

Cracked intercooler maybe it starts whistling when I'm almost out of vacuum like at 10hg.

 

Pull the bumper cover when you do your boost leak test.

 

Do you have gms1?

 

No, I have HPT e47.

 

what codes come up when you have a cracked intercooler or a torn bpv? just curious

 

how do you change a wastegate solenoid and what is the best replacement one for a stock turbo
