driving home tonight cruising at about 80-85 for a long period, went to overetake and the boost gauge will not go past 0 or into positive zone.

Drives as if no turbo, now.

there is no smoke or noise - but exhaust note is very quiet,usual burble not quite so noticeable!
the car is a MY96 with full decat - sccobyclinic modified ecu , new coil pavks andplugs recently, and with K& N cone filter.

car was driving great previosly.

at a loss what to do , diagnose, trying a ecu reset by disconnecting battery for an hour or so.

Anyone any idea!!
thanks in advance

 

Just check all the pipes from the turbo to the boost soleniod etc. One of my pipes that T's off the manifold had come off and it created the same problem, gauge not going past O.

 

not sure what pipe are what, i will check now!

 

no can't see any loose pipes, but then again i can't identify the boost solenoid- i assume its somewhere to the left hand side of the intercooler?

 

Boost soleniod near the left strut, by your KN

 

i think i found it , i took off the small inlet pipe to check, i can feel a slight vacuum with finger over pipe
i could not see any other leaks! no hissong sound, prob is getting dark !!!
