Ford Galaxy TDi Losing Power

If the engine suddenly goes flat right across the rev band after asking for full power (up the hill) then you have a turbo boost control problem, and the ECU is entering LOS mode.

If its flat all the time (hill or not) then suspect the MAF.

Tim,

that's exactly it! Should I be taking out a mortgage to get this repaired? Is there a control unit that needs to be replaced, or is it a new turbo job?

Many Thanks

Sounds like the Turbo has failed.

I would get it diagnosed by a dealer or someone with VAG-COM it most likely will say 'Charge Pressure Control: Positive Deviation'

Depending on the part number, Turbo Active are £351 - £546 + VAT which cheaper than VW/Ford (see under VW Sharan)

Would it still be fairly nippy around town in 2nd/3rd gear if the turbo had failed totally?

problem, and

Not sure if this is any help but it sounds like a problem with the variable vane thingy on the turbo. I think it is being discussed at

atthe moment. The guy there is stripping down his turbo to free stickingvanes. He was having the same prob as you but only when cold...

Thanks Richard, I'll keep an eye on that!

Take a look at

There's a VNT turbo stripdown on there. You almost certainly have a sticking VNT causing overboost and then the ECU shuts off the turbo. Interestingly, Turbo technics claim that the turbo can't be stripped and rebuilt without expensive test gear and reccomend a new turbo, but they would say that.......

It might not be the turbo itself anyway. You should check the VNT mechanism for movement (probably best from below), and check the vacuum piping and N75 valve. It probably *is* the turbo though :-(.

It will probably be OK much of the time until driven hard- then the turbo overboosts.

As also seen in a recent Car Mechanics magazine concerning a clocked Sharan, except the turbo was also very shot as well. Same symptoms and limp home mode engaged.

Define 'failed' ?

Thanks for your input everyone. My mechanic has had a look, and despite suspecting the worst (turbo) tried all the hoses first. Found two split hoses. With these replaced she's running on top form again.

Many Thanks.

Your posts references a Punto so is the problem with a Galaxy or Punto?

You post has this reference.

Also, it was asked in 2005, so it's either been fixed or is on the scrapheap by now.

Given how long ago it was and that neither car in question was new at the time there is a very high chance that both have been fixed in 2005 and scrapped sometime since.

that doesmnt answer why it goes away if u switch off and on....

14 years later do you think anyone cares?
