Title: Lack of power mk2 Galaxy 1.9tdi sept 2000
Post by: G0NMY on December 06, 2015, 04:40:03 AM: Hi Guys,
First off let me state this is my first ever diesel anything so I am on a big learning curve.
So I acquired my MK2 Galaxy a couple of months ago with known issues (Previous owner says needs a new turbo)
It was cheap so I didnt mind.
I have been reading lots of posts on here which is excellent for me to learn.

Anyway I hooked up VCDS yesterday and got the following info.

VCDS-Lite Version: Release 1.2
Saturday, 05 December 2015, 14:22:20.

Chassis Type: FG - Ford Galaxy
Scan: 25,01,02,03,08,09,15,16,17,18,19,22,29,35,36,37,39,45,55,56,76

-------------------------------------------------------------------------------
Address 01: Engine Labels: 038-906-019-AJM.LBL
Controller: 038 906 019 BF
Component: 1,9l R4 EDC 0000SG 1088
Coding: 00002
Shop #: WSC 00020
VCID: 5CCB1773DF33
1 Fault Found:
17965 - Charge Pressure Control: Positive Deviation
P1557 - 35-10 - - - Intermittent
Readiness: N/A

-------------------------------------------------------------------------------
Address 03: ABS Brakes Labels: 1J0-907-37x-ABS.LBL
Controller: 1J0 907 379 P
Component: ABS 20 IE CAN 0001
Coding: 12702
Shop #: WSC 00788
VCID: 3E0FBDFB296F
No fault code found.

So reading lots of info on here has just left me a little confused, so I thought I had better make a post
to ask you experts.
I have never used VCDS before and my interface is a cheap ebay one but does appear to work.

So I don't know if turbo is actually faulty but my car does whistle lol
I don't want to spend money on a new CHRA core only to find out that the turbo is fine.

So where do I start?
Im just looking for a little guidance
Thanks for replies Mark
:)

If sticking there is a way of cleaning in situ using silicone tube and mr muscle, do a Google search there is a how to on the net

Post by: johnnyroper on December 06, 2015, 08:52:15 AM: That's assuming basics like vac hoses etc been checked and are ok?

Post by: insanitybeard on December 06, 2015, 10:35:05 AM: Positive deviation is overboost so a sticking VNT mechanism in the turbo would be a strong possibility, or a dodgy boost control solenoid valve. I'm not sure if a duff MAP sensor could also cause this code, perhaps somebody else can clarify?

Post by: Chrispb on December 06, 2015, 12:22:53 PM: Sooted up turbo vanes is the most likely cause.
Changing complete turbo is the quickest but most expensive solution, cleaning of the turbo vanes would be my first choice either by removal and dismantling or by using a turbo cleaner like innotech cleaner kit but bare in mind still requires an amount of dismantling.
If you have excessive play in bearings/leaking seals or turbine damage then a CHRA is another option.

Have a look at links below if you haven't already.

Post by: G0NMY on December 06, 2015, 03:05:29 PM: Ok thanks for the quick replies, Just an addition when i first got the vehicle and opened the bonnet i spotted a hose off the EGR valve, I think it is called, so I just pushed it back on do these vacuum pipes need to be crimped on or tightened with a jubilee clip?

Also how do I test the boost control solenoid that was mentioned?

I have seen these on that four lettered website ;D for £80 and I was wondering if it is the correct one for my car and if others have bought off this seller etc and are they good quality replacements?

Sorry for all the questions cheers Mark

Post by: insanitybeard on December 07, 2015, 12:05:34 AM: I think usually those vacuum hoses are a tight enough fit on components for clips to not be necessary, I'm sure most of them aren't fitted with clips from the factory on the Galaxy.

Not sure how you can test the boost control solenoid easily, I'm assuming the more boost required the more vacuum the unit should let through but I don't know how this is regulated electrically- either pulsed or by the amount of current controlling how far the valve opens, it'll need somebody more versed in electrics than me to answer that.

Post by: johnnyroper on December 08, 2015, 08:51:45 AM: I found the only vac pipe with a clip was on turbo solenoid rest are just push fit.

The VNT is control by varying the ground at n75, it receives constant 12 volt but ecu varies the ground to determine how far solenoid should open depending on boost pressure. This in turn then operates the VNT to alter exhaust flow across the vanes of the turbine.
