My so-called "wastegate control valve" is sometimes clicking like crazy if I turn the key to Ignition (before starting). After starting the engine, it stops clicking.
Itīs the thingy in this pic, marked "I". As far as I can tell, itīs supposed to be the wastegate control valve, hooked up to a bunch of vacuum pipes and itīs attached to the coolant hose as indicated in the pic.
Is this clicking behaviour normal?
If it means anything - the front end of the car is lifted approx. 15cm and temperature was about 5-10 degrees C. The car had not been started for a couple of days.
the question is what the normal function of the wastegate control valve is.....
(at least to me) it would make sense to have the wastegate open fully when the engine cranks to ease starting. Thus perhaps the ECU would activate the valve until the engine starts. In which case the clicking could be caused by a bad connection.
I think Iīll do a lamp/multimeter test tomorrow to check whether itīs the ECU going crazy or a bad connection before I attempt driving the car.
I did do a bit of messing about with the intercooler pipes, but I just donīt see how that could affect the engine at least until I crank it. Oh well.
Thankfully Cally is in winter standby + modification mode ītill I get the cool stuff from Gavin.
