Boost stops at 1.4bar - N75?

[Rikki Kitto]

Got an injector you can have buddy let me know if ya want it

[hunker7]

Visited newsh yesterday to do the boost test. Discovered boost leak by the wastegate and one of the injectors were leaking, dumb valve was "kaput" too. Now that's all sorted and the damn thing still isn't running, and if that's not enough, one of the injectors died.

I call it "tough love".

He needs some incentive to get in there and get it done.

And BTW hunker7, a boost leak WILL occur "overnight" (or instantaneously) when a boost host splits. Re-read my post on AAN boost leak testing.

I am now making friends with gavs20v, and hope he can help me with boost test

Where is that monster? Also when i rev it and let it go the inlet pipe pulses if you know what i mean.

Click on the URL below and open up the live version of my engine bay device map (and then book mark it for future reference).

Then click on the F96 Altitude sensor box in the upper left corner. It should tell you what you need to know about it.

But you still need to do that boost leak test to eliminate split hoses from the equation.

No idea about vagcom I'm afraid. Have a search on here about it, there's lots of info on how to test and adjust it. The basics of it is measure resistance over pins 1 and 2, should be around 1200 ohms. If its more than that then carefully prise the retaining lugs apart, open the unit and bend the metal tab until resistance is correct. Mine was reading over 1500 ohms and I adjusted it to just under 1200. It sounds tricky but its actaully very easy to test and modify once you have it in your hands. Once open the way the unit works should be self explanatory

[hunker7]

How can I adjust it? Can i see what it sees in vagcom?

Passenger side, behind kick panel under glovebox. If the inlet pipe pulses after revving it, that would say to me there's possibly something wrong with the dump valve...depends how big the pulsing is I guess

Under the carpet near ECU.

Have you checked the altitude sensor yet? My boost went from 14psi up to 19/20psi just by adjusting that alone

It does seem like a boost leak, as yesterday managed to squeeze 0.8 bar at 100mph. gavs20v you got a PM

[AndyP]

If you ever come back up to Leeds, give me a shout and I'll help you leak test it

[gavs20v]

I have a compressor , air line and boost test kit and work in Edmonton ( nth London ) only problem is I'm on holiday for a week from Tuesday .
I f you want to borrow it let me know , failing that wait till
I'm back and I'll do it with you
