Oh i forgot to say the AC also stopped working at that time.. i assume its a protection thing to save load on the engine as it would not let me past 4k in any gear and barely any bost pressure.

 

i would clear them amd scan again next week ?? see waht re appers ? i sure i read some think about flat ish battery causing a load of faults ! is it spining over fast ?

i prob would put ya battery on charge would not harm ?

 

ill pop the batt of tomorrow and see if a ECU reset clears the faults.

Batt is fine, cars a 57 plate and there is a good turn over, ill grab my muliti but 99% sure its not that.

Nope car is idling fine and runs fine, just a little jacking in power.. did notice the other day it was idling a little bad, but i think she needs a service, just wating on ford.

 

Sounds like the battery is on the way mate

 

Really... i will be bloody amazed if it is.

i shall wonder down and get one in the morning, keeping the receipt

 

I would agree with Dave and add that it could also be the alternator about to go boobs up?

 

Bah all ganging up on me

Ill swap out the batt in the morning as its easier to get to

That alternator looks like its a pain to get to, however im sure i can meter it.

Is there a manual for the ST? not sure if haynes have done one, from what i have read the answer is no.

 

I dont think there is a specific Haynes manual for the ST but i think the general Focus one has some info in it! Youre best off getting the battery and alternator tested by somewhere with the proper diagnostic equipment! Metering it with a multimeter wont show up all the problems that can be occuring!

 

The joys of owning an ST!

ill have a lookie at the focus manual, however haynes site says it does not cover the 2.5l. Ah going in blind, love it

ill see what the lads at the local garage are doing, dont really wanna take it to ford as its going to cost a bomb, having said that a diag should not be to bad.

thank u kindly x

 

Noooooooooooooo Ford are the last place you want to go! Find a good independant that are up on electrics! There are some wonderful meters now that can tell you exactly what the problem might be but they are expensive! The alternators are a bit of a weak point on the ST too! When they go ****y you get all sorts of weird errors cropping up

 

Yeah i do try and keep it away from Ford to be fair, going from the 1.6 VTS to this is a little more complex and inaccessable!

The Batt does seem strong, not showing any signs of a voltage problem like i would expect, however im again basing that on my years of saxo experance.

I assume the system faults are preventing the AC from working as well due to the extra load and stress on the engine ?

What would you put your money on?

 

Might go and make sure all the earth contacts are good in the morning, Garage covered them all in white anti corrode powder. Makes jumping strarting the wifes car a

at times

 

Update: Not batt or alternator.. Tested by the guy at my local garage. Meter readings confirmed all good..

Thinking its the MAF now as she did run a little lumpy the day before so the wife says.

 

Anyone local to east Sussex who fancys letting me test with there MAF? Drink and food included

 

Another update,

Took it in to ford and spoke with a really good bloke, ran it over there diag machine, and 1 good thing, I know why my windscreen sensors don't work

He said it looks like its a wiring on earth fault, so... Out comes the sockets again. He showed me where to look

 

Ok, so it seems that this ST has had a possible earthing fault before, as 2 of the contacts has been cleaned and copper greased before, I cleaned up another 2, but it's made no difference.

The wiring over the engine block looks ok.

All the connections in the to ABS, and ESP unit are good.

I've not checked the ECU yet.

The ford diag also said the AC clutch unit was bad, so that's a grand total of 7 "random" faults.

They all clear OK, and key to position 2 still shows them as ok, it's only when you start the car.

Now, the diag says the MAF is bad, and given its above the ECU, I was going to assume the wiring loom for that was direct to the ECU, so I can follow it and test.

Has anyone got ANY ideas?? I'm assume it's something central as its affecting so many things but. Have. Idea what.

Was thinking of contacting the old ford garage that dealt with her and asking if they have any notes on this happening before.

 

Ok so problem "part found" noticed someone else with the same set of error codes.

Turns out its fuse 35! However replaced, just blows again... Anyone know where that feed goes?

 

Ok,

Fault found by myself rather than Ford

Guys there are great as they printed of loads of circut digs for me

It was the sensor on the oil filter housing (see attached) Not quite sure what it does.. thinking of getting a new housing or doing a good repair..

on a side note, that F*ing air box is a nightmare to get out !!! Might replace it but ive no idea with what.. any advise (looking to go to stage 3 in the next few months)

 

Well I went for the fix option as need to do intermediate drive shaft bearings as well.

Spent some time and repaired it, did 100mile today and all seems well

Anyone know what the sensor does?

 

Not sure what the sensor does mate, well done on finding the issue though. 7 random faults has to be very unlucky

 

Hey mate,

Thank you for your kind words

Well it's been a week now and all seems well in ST land

had the drive shaft baring done, however they found a leak with the high pressure PAS pipe. So will need to get that sorted next! Ten it's due for a huge service.

Might have to live with stage 2 instead of stage 3 for e short term
