**Eshrules** · 15-10-2006,05:17 PM

once again guys, i need your help please! going down the motorway the other day, lost all turbo power after i shifted out of 4th at about 2900rpm into 5th, no power whatsoever, pulled on the hard shoulder for ten mins and it was back to normal.

everytime i rev near to 3000rpm, it does the same again! trouble code has been logged, but no engine check light trouble code being :

17965P1557Charge Pressure Contr. Positive Deviation
any ideas guys?

Hi there charge pressure control valve faulty by the sounds of it, quite common. Its easy to replace costs about 65 pounds for a genuine one.
Thers no real way of testing it unless you have access to a main dealer computer.

Hope this helps

well the dealer took it into a garage yesterday, apparently the code relates to a 'hose' that has either split or come off from the VNT? something like that anyway, but this garage reckon that replacing or refixing the hose will fix the fault...not convinced that its such an easy fix myself?

thought i would keep everyone up to date on this fault as it would appear it is pretty common on these engines. after a 2nd trip to the 'mechanic' and me telling him how to do his job, he has prescribed a recon turbo. not sure why the old one has 'worn' though, as i always thought turbos were the kind of thing not to wear or just 'fail' if its failed, surely there must be a reason? or is it just one of those things?..... anyway, the dealer i got the car from i must say has been less than helpful with the whole situation, the first time it went in, a MAF sensor off another car was swapped with mine! dont know where the sense is in that, but my car was then sent out minus the 'new' maf, they had swapped it back with mine and tried to say the fault was rectified. i have asked for a copy of all invoices and written proof that an exchange has taken place as far as the turbo is concerned. caveat emptor is ringing very true right now!!

Hi i have the same problem as you and the same fault code. any ideas on how to sort it out i have checked and replaced some of the hoses on the turbo and they seem to be fine however the problem still remains do i need a new turbo ?

**Eshrules** · 03-11-2006,10:03 AM

it could be caused by the MAF sensor as well, im not sure how you can test to see if thats the fault causer, as the MAF is nothing to buy and replace compared to a recon/new turbo. they tried a different MAF on mine, wasnt happy about that but it showed it wasnt the MAF that was at fault. all i can say is,given the investigations that took place, ie new hoses & MAF sensor, the only thing left on mine was the turbo, stuck a recon on it under warranty and its been fine, plus the economy is closer to the figures i was expecting. have you actually had this into a garage? even if it does come to a turbo replacement, recons are around £250, new ones around 350/400. its the labour thats going to bite, unless you know someone who can do it for you.

just one thing that i need an answer on anybody please, when im putting my foot down in 2nd, the car boosts as normal, hesitates for a second or two and then sets off again, is this normal? im sensing not?

Hi i have already put a new maf sensor on the car and nothing has changed i am going to check all the pipes today and if i cant see any obvious damage to the pipes then i will have to take the turbo off and see if there is any damage to that and if so replace it thanks for advice.
