Galaxy Power Problem

[seatkid]

dave_m - you may have a faulty boost control solenoid or wiring fault to same. (Short to ground fault) - this leads automatically to no boost (Negative deviation)

 

My advice to everyone else - after eliminating the MAF, change the Vacuum control pipes to the boost control solenoid and turbo.

I have had the Boost control Solenoid replaced and the wiring has been continuity checked by the dealer.

 

They could not resolve the problem.

 

any other idea's

Vacuum control pipes - look for a small hole or split. If necessary take the pipes off, one at a time and submerge them in water, giving them a good squeeze (like how you find a puncture in a bike inner tube). Make sure you clean and dry them thoroughly before re-fitting.

Hurrah, I have found what is causing the intermittent loss of boost on my galaxy.

 

See photo's to make sense of my descriptions....

 

I followed the several vacuum pipes that are connected to various control aspects of the Turbo and one in particular goes into a Plastic Black ball shape on the front of the engine and is connected to this via what looked like a rubber bung.This is the Vacuum Reservoir according to my TIS disk. I think this pipe may head for the boost control Solenoid but i'm not 100%

 

Upon further inspection this was found to be a very loose fit and seemed to be a funny shape like it had split/separated from the bottom of the hole it was connected into. In fact it could even be that the connection on this vacuum reservoir is broken and the rubber bung is someones attempted bodge at a repair as it does just look like a bigger bit of hose around the smaller piece.

 

I tried driving the car with this completely disconnected and had no turbo boost at all so i tried putting a bit of white insulation tape round the rubber plug to seal it in the hole with a much tighter airtight seal. Took it for a test drive and it had loads of power like it used to been about 60 miles and car is fine whereas before it use to be ignition on and off every few minutes to clear the problem.

 

it may not be the same problem on all of your cars but certainly worth checking as Ford did not find it on my car, I may try and get back my money from them for the failed diagnostics as i feel they should have checked for and spotted a vacuum leak before they changed the solenoid/maf etc.

 

See these photo's for a clearer picture of what was wrong. and thanks to everyone on here who has offered help and advice to me on this <_< <_< <_<

So the problem/solution was staring you all the time in the face! <_<

 

Reckon vaccum piping accounts for a lot of faults on these engines.

 

Well done, photos will be a great help for others looking at similar gremlins.
