Try giving www.autovaux.co.uk a ring (preferable method than emailing them) and see if they can help.

Which is why I suggested calling autovaux as they *might* get you one quicker than Vauxhall can.

that pipe is linked to a pressure sensor for the turbo, look on the radiator on right hand side as looking at front of car on slam panel above radiator. 2 rubberish hoses coming of engine. get some 6mm heat resistant pipe (guy on ebay selling it as 150bhp vectra but fits 120. Just be gentle that when taking pipe off the sensor. takes 10 mins tops and only needs you to cut pipe same length as old pipe and ensure you dont catch pipe under engine cover.Also make sure main boost pipe (big bloack pipe going into to side of engine) is fastened on and sealed as this will also cause problems

Hi, Thanks for the info, I lost turbo power on my Vectra this morning and thought the worst, took it to my local garage who told me the fault was P0234 (only charged £20, thought this was good) . Checked out this thread and checked my hoses, found the top hose from the sensor split at the engine end, temporarily fitted another hose and now have turbo back, will source new hose soonest. Once again thanks for the help.
