Had the car in ford this morning with a possible solenoid failure as its either overboosting something rotten or only giving a quarter.the workshop foreman came back to me and said no fault code found.when the solenoid goes up the wall will it always give a code or not at all.

That's pretty much what I've got no code so all is well yet it still won't boost or goes totally nuts.time for a swift butt kicking I think.

This is what happens when mechanics are now trained to trust software rather than the basics of mechanical engineering.

If it hasn't got a fault code then it can't be broken, and if you still want us to look for the problem we will charge you hundreds and tell you its something else which is in most cases also hundreds of pounds more


You would be better off with a Haynes manual
(if they did one for the ST!
)

But again, the boost solenoid doesnt always bring up any errors, it may bring up overboost and underboost but not always, particularly because the ECU has to see the fault properly rather than intermittently.

Like the guy on here who was told that his quarter boost was being caused by a
turbo. The only solution: a brand new turbo. Cant remember the price they quoted him but it was well over a grand.

He posted on here, someone said "check the solenoid" and voila, a working car.....

Tell them that you have had it diagnosed by a turbo specialist and that the boost solenoid will be the problem and that with a week of the warranty left to go you want it tested with a new boost solenoid.

Then advise them that they make thousands by talking rubbish and misleading people into getting expensive work done to their cars because they have no idea about whats going on unless a DTC with a flow chart can point them in the right direction, and that a £50 part won't break their bank and their secret of not knowing about this common problem is safe with you


Failing that, get it reported as a problem before the warranty runs out and then ask for the contact details for someone at Ford who deals with warranty issues at Ford rather than the dealership and get on to them.

I wish the warranty was with ford but I bought the car through a place called the car people and they use TWG for the warranty.I have reported the problem to them on Saturday.the only reason it was at ford is because the car people don't have diagnostic equipment and the fact that their so called fitters are a bunch of orangutans.i just feel like a being fobbed off and nobody wants to know.they are now saying they will take it to ford and charge me to diagnose this fault.a fault with no fault code.so all ill get is its fine nothing wrong with it.might just buy the part and do it my sodding self.

You may find if the boost solenoid is knackered it will throw up an overboost condition and put your car into ESP if it is going nuts on boost. If it only boosts to 1/4 scale it won't recognise a problem.

How can they offer a warranty on a Ford car if they havent got diagnostic equipment and then need to take it to Ford to find a problem, more importantly if the car is no performing as it should then why do you have to pay for Ford to diagnose the problem???

I would be taking advice about that mate, if its a warranty issue and they agree that it needs to go to Ford to find the problem then they should be paying to get the car fixed as per the warranty. Regardless of them being clueless or not!

If you are handy with a pair of long nose pliers then it would actually be just easy for you to do it


(it's extremely easy if you have access to a ramp)

That's the problem with it, it doesnt always store any mention of it overboosting or underboosting, nor does it mention when the boost starts spiking on gear changes etc, but Ford are well aware of the boost solenoids being a particularly weak part and they only have to ring a decent Ford garage and mention the symptoms and chances are the local Ford garage would have a solenoid in stock
