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

   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

First thing I would check is for sticking VNT the vag engines are prone to it,see if you can move the actuator rod on turbo by hand. 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

That's assuming basics like vac hoses etc been checked and are ok?

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?

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.

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

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.

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.
