   I reminded Ingo during my phone diagnostics many times in the last 2 weeks, it's only sheet metal.   Spark and fuel...  Now maybe I can retrieve all my shipped tools and 'known goods' back to my urq parts warehouse.

  Fascinating! 
   
  I must say I am very relieved for you Ingo. Glad you found the culprit and can now get back to enjoying the car.
