It's a miracle when you get an actual error from bad cps. Usually it's just random cylinder error.

You want OEM quality but you can possibly get a cheap local copy to hold you over. Which engine?

When DME finds any fault in the vanos it shuts down all the attempts to use it and it will drive like crap because the timing is off except for some very limited RPM.
