Ok so the last 2 weeks iv been trying to get to the bottom of it, some times it will boost up to 0.7bar wich is wot it is ment to be and out of nowhere it will drop to 0.5bar and go no higher. You can start the car and when you rev the engine you can feel the boost control solenoid clicking and other times you start it it won't there r no fault codes on the ecu. if anyone can help that would be great
Thay are not a specialist if thay our only do a vacuum leak test. I am a air conditioning specialist and every car that I do is pressure tested to 10 bar it is also how we look for leaks, so to be honest why thay are only doing a vac test I do not no.
that is only for R134a in cars this dose not inclued R1234yf of R1234ze
forgot to say but it should definitely not lose more than 15% in 1 year no matter wot gas its on and if it is you should think about getting the leak found try and avoid people putting UV dye in there as it is not good for the compressor if you live close to Cardiff i can find the leak for you

Right ok now on the way home 0.7 bar and it ran like a dream no problems Wat so ever. I then go out to go to the shop wich is 5 miles away and 0.5 bar again. I do not no wot is going on someone plz help I'm so confused
Ok something odd happend today driveing back from work today and the boost flue up to 1 bar and the fual cut came in it kept doing that for about 2 miles then it went back to normal at 0.5 and no matter what I did it would not go above that and then as I got close to the house it did it again
So confused
Right changed them today drove home from work and it has got better but there was a hair line crack on 1 pack down the side would that be the problem do you think,

no mods yet and plugs and packs r next on the list as iv only had the car for 1 month now so i don't no what they r like, iv had a look for air leaks cant seem to find any, would it be a good idea to get it smoke tested?
it seems to get a bit lumpy around 4000rpm and then clears up from 5500rpm but if you have been giving it some for a couple of miles the boost pressure seems to drop off and the blow off is not so loud, now i have already changed the o2 sensor and knock sensor and it seems to of helped.

Could you test the solenoid and see how many ohms it is as im not to sure if it is dead or not now
and i need a v1 or a drop in replacement as im not going into to mapping yet, thanks
