Chain Tensioner Electrical Sensor Gasket

[A4Ncar]

Does any one know, if a gasket is available for electrical sensor that gets attached to Chain Tensioner (058-109-088E Cam Adjuster Unit)?

Mine is leaking right where sensor flanges upto the tensioner unit.  The sensor is held in place by two screws.  Can I just use Audi/VW sealant to form a gasket, and re-attach the screws?

I'd just use sealant

Just an update, the bottom screw broke while tightening. So, took it to machine shop this Saturday and they drilled at tapped for a new stronger screw while the tensioner was still mounted on the head.  There was green colored o'ring seal inside.  Re-installed using the o'ring and high temp sealant. No oil leaks so far.
