How'do folks :}
as of Monday i'll have owned my car for 8 weeks. I'm starting to get some jobs done - maintenance and personalising - replaced the tyres, boost control vacuum hoses and stereo, fixed a small oil leak on the cam cover and cleared up the leaked oil from the plug chambers etc.. gapped plugs (0.80) and got rid of the misfiring i was getting :cool:
currently the car runs well.....however :D .... my overboost issue :duh: (i had a misfire and overboost issue under full throttle) seemed to be gone after fixing the oil leak and gapping the plugs - cured the misfire and initially i had no overboost - foot to the floor the car was pulling really smooth and with the intended linear power delivery (no spikes or troughs) now if i floor it i can feel the overboost and hear the turbo spooling(?) i can tell the moment the ECU is about to cut power - obviously i'm driving more sedately for now, i'm more of a cruiser anyway but i want to know that this problem is fixed and that the power the car is intended to have is there for those times when it's needed ;)
after changing and re-checking the vacuum hoses (3mm I.D silicone) i assume it must be either boost control solenoid or faulty wastegate actuator - i've checked best i can for the wastegate actuator being seized and it seems to be moving, i also heard a bit of hydraulic type sound as i moved the arm. is this normal ?
i'd like to rule out the wastegate actuator before changing the solenoid - are there any issues r.e bypassing the solenoid ? - connecting the compressor to the wastegate actuator directly - and would this allow me to diagnose wether or not the actuator is faulty ?
anywho...lol....my main question is r.e replacement boost control solenoid :D
i will buy a replacement this week coming.
does anyone have any advice/experience of aftermarket replacements over the original units ?
i can get a new original unit for £40..ish and i've seen aftermarket units for a similar price. i'd like to stay original however from what i understand the original units are prone to failure, so maybe an aftermarket unit may be better :shrug:
