At 150k km the supercharger did, unfortunately sometimes, not kick in when putting your foot down at 40m/hr. No relationship with hot or cold engine. It appeared to be the crankshaft sensor. At 300k km same thing. I replaced crankshaft and camshaft and temperature sensors. Checked the supercharger elektromagnetic initiator. Found that the intercooler (below the supercharger) was toast and replaced it. Replaced the coil. Ignition is not the problem. All injectors work and all temperature readings are ok.
Does anybody have an idea in what is the problem here? I know the distribution chain has slack because the crank and camshaft show an angle difference, that could be the problem? To replace this I need to take the engine out which I would rather not 😂.
I want to take the car to at least 500.000 km 😄 and will never give up on my baby.
Thanks and kind regards,

The first thing I'd check is that the intercooler circulation pump is in good condition and is running. If it is then don't worry about the rest of my post, but if it isn't then read on. The IC pump is protected by a 10A fuse and is switched by a relay in the Pulse Module. The relay in the Pulse Module is controlled by the ECU.
I don't think the problem would be with your ECU, but if it doesn't see any current flowing to the Pulse Module then it wont turn on the Supercharger Clutch. So I guess what I'm saying is, check the IC pump fuse and if that is OK then I'd check the output of the Pulse Module (or just plug in another Pulse Module). Your car has very high mileage and the relay in the Pulse Module could be worn out.
If it is the Pulse Module and you're having trouble getting a replacement, then you could also use a normal 12V Relay to do the job. The ECU would control the relay by providing a ground to the relay coil.
