My car keeps dropping boost to 0.5bar, and the only way to put it back to 0.9 is to disconnect the battery.

I'm getting bored of it now so if anyone knows why it would be doing this and/or how to fix the problem please let me know! cheers.

 

try this test http://www.jollygreenmonster.com/error_codes.asp.htm this has always helped me

 

there are no codes mate, but thanks anyway

 

the ecu isnt happy, what fuel are you using,
if it was mechanical it wouldn`t clear with a ecu reset.

 

i use 97 unless 99 is available but i live out in the sticks so ive got to travel 15/20 miles to get 99 haha. do you think it could be due to that?
