Hi everyone - more worries reflecting my deepseated insecurities - the group has become my blue security blanket.
2.3 Stg1. In 4th gear max boost shows as 1.3 bar or there abouts.
Almost straight away the boost falls to 1 bar and fluctuates between 1 and 1.2 bar cycling in about 3/4 of a second and then stabilizes at 1 bar after 3 or 4 seconds. The turbo can be heard spooling up and down.
Spool up is almost instantaneous - max boost is reached very quickly.
In lower gears accelerating hard from low revs there is a slight tinkle/rattle - Pinking? only lasts half a second or so - no back off in boost.
is this normal behaviour or is it indicative of a fault? - perhaps a weak wastegate actuator?
Cheers
Alyn
