after almost 18 months of abstinez from this forum I am thrilled that (almost) everyone is still there...

due to child's blessing and house purchase/remodeling I had no time for my big one anymore. since I wanted to do a bunch of things on the audio I just logged him off and put him in the hall...

So I did the following:
-motor oil tank and sealed
- transmission oil tray from and oil and filter changes
-lights/reflectors new
-stabi restocked
- all suspension rubbers front and rear replaced
-cooling water + thermostat new
- new painted bumper
-motor bearings renewed
-detonate all new
result: I was standing in front of it with a screwdriver beer today and was back and forth as always...

then came the disillusionment: the thick one does not start!!!
all the desperate attempts of me and the hall boy were in vain...I also screwed out a spark candle after old manners and realized that when I was orgling, unfortunately, there is no spark in sight...

in my distress I called the adac at the...the angel struggled honestly and diagnosed: there was 5 volts missing on: air mass meters, temp sensors, empty-running controls... etc....
so it is said 5 volts unfortunately not from the control unit...

... aber davon abgesehen: Warum denn nicht zuerst mal den Fehlerspeicher auslesen, bevor man anfängt zu schrauben ?? Das ist doch das naheliegendste, oder ?
