Hi has a service with Subaru in Cardiff.
Turbo is boosting at 440MMHG ? it supposed to be boosting at what ?

Gear box spring is ****ed so gear box spring needs to be re-newed to line up gears so they say and cost ? what is to be done ?

If you are saying you have lost boost immediately after service check your oil level. Alternatively look for a leaking or loose hose/jubilee clip etc.

Should have said too much oil and your solenoid valve may need cleaned out. Simple job.

No it has been like this a while I thought it was fuel but I have been on optimax now for 5 tank fulls so I thought subaru could sort it out.....they did think it sounded like overboost till they drove it and put the gauge on there and it showed up at 440MMHG.
they said they could do further testing but they charge buy hours they research the problems and at their hourly rates **** that !

Get some brake cleaner(Halfords or anywhere) and take solenoid valve small rubber pipes off and run cleaner through valve.

Thats actuator pressure only which means its not got boost control, either you have a solenoid not working, or, the ecu has "dropped" the boost due to thinking that your car was suffering detonation, do an ecu reset to prove this, if you can't do the connector routine just disconnect the battery for about 20 mins. if its ecu safety related then it will come back.

440 mmHg is approx 8.5 psi
so yes, is low

Depending on MY and mods etc, you should be getting at least 11 psi and probbaly more like 13 - 16 psi
