Still Stumped

[bilko0795]

Right having found a boost leak a couple of weeks ago on the I/c i bought a new O ring and at the same time decided to change all the boost hoses to the silicone ones i bought from the group buy. so i thought to fit the homefry ecu i have and straight away had the same probs as before. So i went back to the standard ecu and the same problem. I have now done another boost leak test and have found no leaks present done a vag com test and it's coming up max boost pressure exeeded.

So Far i have changed

All coil packs

All Boost hoses

New N710 valve

Cleaned the Maff and ISV valve with carb cleane

Is there anything else anyone can suggest i can try.

Getting any fault codes?

What are your issues for those of us that haven't been following?

Blocked breather pipe?

Found this thread maybe it can help:

Maybe plugs, an inspection of them can't do any harm

Or your MAF has kicked the bucket

The codes that came up are these


Address 01: Engine Labels: 895-907-551.lbl
Control Module Part Number: 895 907 551 B
Component and/or Version: 2,2l R5 MOTR.RHV HS D01
Software Coding: PMC 1
Work Shop Code:
VCID: 2343A0E3B1D704001CE
3 Faults Found:

00544 - Maximum Boost Pressure Exceeded
27-10 - Implausible Signal - Intermittent
00537 - Lambda (Oxygen Sensor) Regulation
11-10 - Control Limit Not Reached - Intermittent
00513 - Engine Speed Sensor (G28)
03-00 - No Signal

Readiness: N/A

[rynaqui]

G28 isn't actually a fault, it shows when the engine isn't running.

It could be your lambda sensor is or bad spark plugs

Have you changed all the small bore vac hoses?

[andy10v]

Have you leak tested the car since changing all the hoses?

No not done these.

Yes done a leak test again yestaday. All i could here was a gurgling sound in the I/c don't know what that was. I am going to test the maff today with vagcom see if that will show up anything.

I was getting max boost exceeded as there was a leak into the lower waste gate chamber. I found it by chance but you can take off that hose and blow down it to listen for leaks around there.

Sometimes you cant hear a leak mate, you need to pressurise it with a tyre inflator or something with a gauge and then watch the gauge for leakdown
There are also things like the injector seats etc that are easily missed if you have just done the pipework.

What about the mark H mod from ic to xmember? I would change all the vac hoses for silicon aswell

You can spray down the pipework with soapy water to help see leaks as bubbles. Is the intake holding pressure whe you test it?

My son has just bought a leak test kit for his car that has a gauge fitted doesn't fit my car, but i have just asked the guy that's going to make one for me to add a gauge to it should have it in a few weeks.

The mark H mod came with the silicone kit i got, i also fitted a new O ring the I/c doesn't sit right now it now hangs low on the right probably due to the mark H mod how many vac hoses are there?
