    Hi fozz .
    with the p0234 code up first thing to do is remove the boost sensor and give the sensor tip a clean , have a look at the how2 s for instruction .
    if this is your only fault code then this should solve your problem but while you have the manifold off you may as well clean this as well , along with checking your hoses and vacuum pipes for signs of splits and perishing .
    if you need any more help give us a shout.
