Yes, this its the Cam Position Sensor (CPS) located on the exhaust cam
(dissy on inlet cam).
On any car with Motronic or Fenix management (not LH 3.2) i.e. those with a
single ECU for engine control, failure of the CPS will cause failure to
Be careful to distinguish from a faulty crank angle sensor on the
bellhousing as this will also cause a no-start.
Arm yourself with a can of freeze spray or brake cleaner, and when it next
dies, spray one sensor at a time to cool it off and attempt a restart. See
which one needs to be cool for the engine to start.
