    HI,

    I recently took my vectra 2.0 ls DI to a garage as my engine light was comming on, he identified that after putnig it on computer that it was a faulty boost pressure solenoid, my question is where can I pick this part up cheap and also where is it located, (please can you tell me in very simple terms as I am no way a mechanic) somebody did tell me that it was near the turbo.

    Thanks

    Boost Pressure Solenoid Valve

    Hello

    I posted a reply to your previous post about the engine management light and sluggish performance at low speeds. I had a similar problem and just found out this weekend that it was caused by a split rubber hose going to the vacuum unit next to the battery. I have had no problem with engine management or sluggish performance since. Apparently the boost pressure solenoid valve (or Exhaust Gas Recirculation Valve) is controlled by vacuum. When the hose is split then it comes off and causes the poor performance. Thanks for your previous posts and the replies you got. It saved me from paying Vauxhall lots of money and all it took to repair it was a bit of gaffa tape. I intend to replace all of the hoses as they are preobably all brittle by now.

    Cheers

    The solenoid is mounted on the bulkhead close to the brake master cylinder.

    I think Bograt's right on the money here with his suggestions, make sure you thoroughly check all the thin vacuum pipes and their rubber connectors.

    Boost pressure solenoids

    There are three of these things on a di one near the driver side turret and two near the battery.I had to replace one on a di i sold recently. It was tje the turbo boost control and it ment the turbo was not working giving me a top speed of 60mph! I went to vauxhall and they said £104 for a new one but i managed to buy two on ebay. Check you have not got a vaccum leak on one of the pipes before you go forking out for one of these you may not need it. If you do need one I could maybe do you a deal.
