C5 electrovalves

Think I put pipes on wrong,could have mixed them up.is there an
In and out on valve,cant find diagram,limp mode again,lol
service light,and check light:-(

what valves mate

turbo and egr valve if you look at it so both nipples for vacume pipes on it are pointing right ,one nearer to you is out feed (giving vacume to turbo ot egr)
far one is permanent vac infeed from pump
both are same valves if you have 2.2 hdi elecrovalves 2 valves for inlet flaps are same tipe valves
swirl flap ev is a difrent tipe of valve and cant be used or swaped with any othere valve

just make sure you got right conection as far as i know blue (egr)
white,gray turbo ev
and folow pipe down to make sure you conect right think to right valve
as i done it before where i conected vac pipe down to turbo on to egr outfeed
hope it helps

Does the turbo have the vac feed from the servo,the electrovavle for turbo makes a humming noise.is that normal

[Gibbo2286]

These any help?

[bill196510]

Cheers for that,got pipes in right place.showing no fault codes,car still crawls,lol
Using torque pro,turbo boost reaches 11psi,how much should it be

[bill196510]

tested output vaccum on all electro valves,good input vaccum,virtually no ouput vaccum on any,voltage to all valves is 10.45 v
battery is 14.48v everything tested with engine running

Remember on the turbo no vac = max boost. If you disconnect the vac pipe to the turbo and drive the car anything a bit spirited should bring up asp/asr anti-pollution fault and limp mode, this is because the turbo will / should have overboosted.
Also bear in mind that the control voltage to the EV's is a pulse width modulated signal i.e the valves open in a proportional manner depending on the time volts are applied against the time that the volts are 0. Reading 10.45 volts with a multimeter tells you that they are open to some degree exactly how much I would'nt like to say but probably more than 50%.
I note from your sig it says good on fuel now what do you call good? and what did you do to it?

I would like to know this also!

about 46 mpg but down to 31 with limp mode. 29 mpg on .9 miles from cold

in garage now. he says electrical fault. and immobiliser fault comes up aswell

[HaydnR]

What did you do to improve your mpg,? I'm still getting only 30 mpg. Considering a v6 as it would be more economical.

[bill196510]

new maff.new turbo electrovalve.new fuel and air filters.
redex injector cleaner.xado in the oil.
works wonders.try it.you might like it
was doing 24 mpg when i got it.
i alway improve performance and mpg
vastly on every car i get.xado is amazing
but must use injector cleaner at same time
v6 will do about 20mpg lol

[HaydnR]

Thanks for the reply, I will have to give it a try. If it hasn't already been answered, the electrovalves have a white mark by one of the outlets, this corresponds with a white ring on one of the two pipes connected to it.

[HaydnR]

Did you use a genuine or pattern maf ? There is quite a difference in price

H

[bill196510]

genuine.88 plus vat

[bill196510]

just did 42.8mpg from alfreton to chesterfield.on A61.
in quite abit of traffic.not an economical route.

did use manual though
