N75 valve and Vacuum ball....
I have an AFN engined Avant A4 and I have boost issues, i.e.the boost drops off quire severely after 3000rpm in 4th and 5th but lacks power going up hill in higher gears... but quite strong up until then (not as good as usual but ok)
I was wondering, as the N75 is a bugger to get to. is there any reason why it cannot be relocated to a different area within the engine bay where access would be so much better should the need arise? (Had new silicone vac hoses installed in June and they have already showing signs of hardening and not creating a perfect vacuum so will be changed tomorrow.)
Is there any reason why the N75 and Vax ball couldn't be moved to the bulkhead near the battery as there is plenty of room there. I know I will need longer hoses and do a little wiring extensions but apart from that, any reason why I cannot do this??
Have had the codes read... Nothing at all...
As for the boost leak, I am having a new set of:-
IP seals fitted this week (Slight fuel leak),
new fuel temp sensor fitted, (whilst the pump lid is off, just in case)
having the timing checked and adjusted,
new N75 and ALL vacuum hoses and one way valves,
N18 and hoses,
actuator IS moving freely,
Turbo only 10,000 miles or less... (GT1749VA)
All intercooler hoses checked, hose couplings all cleaned and jubilee's tightened...
Will be doing a system pressure test tomorrow...
Any other suggestions??
