Although the wiring harness must be properly designed and sorted anständigt (the connecting cables for the rear doors criss-cross through the cable for the front), but after a few minutes and a little tape around the individual cable strands to fix lets it block perfectly now.
Instead of a rear door, now the trunk lid is tuned (ie cable extend - but not a problem).
The additional function to open the trunk lid is also great. (But if the damper flap be strong enough - in old steamers there can be problems.
While the extra-mitbestellten key blanks look good, but unfortunately 0.7mm too shallow. The ignition was, but I could not open the doors from the outside. Therefore prefer the original key file handle - a precise dimensioning of this is included in the instruction manual).
All in all, really offer something for the money.
