Thumbs Up jtd 16v turbo overboost

Remove the turbo and clean it fixed my problem in 5 hours my turbo was clogged with carbon causing the variable vaines to stick first remove the turbo tricky but possible took me 2 hours im no mechanic just a diy'er remove the actuator from the turbo small clip i used a little hook remove exhaust side of the turbo case 5 10mm nuts gently tap off casing to reveal the variable vaines there are 3 star bolts holding it all on recover the 3 spacers and keep safe clean all the carbon and make sure the variable vaines all move nice and freely then simply put back together reconnect to car i used new flanged nuts for the turbo from alfa romeo 1.50 each and a new cat to exhaust gasket 6 quid a mates code reader to clear the mcsf light and hey presto saved myself a fortune happy days

Welcome to the forum and good work on the turbo. This problem with stuck vanes is more widespread than people think. Most mess with map sensors etc first.

hi thank's for the welcome just hope this saves other people money as most garages would just bang on a new turbo and charge you a bank loan .
