Hi to all, i'm Claudio from Italy
I have this problem:

https://forums.audiworld.com/a6/msgs/424238.phtml

many days ago in my A6 2.8 Quattro Tip of '98 and 210.000 km on it.
I have read the complete 3d and other 3d inside, like Bentley forum and i have disassemble the ABS block with remove the 6 torx.
Open the elettronic module (8D0 614 111 A now E), found a terrible SMD VERY small ceramic module fitted in a trasparent glue.
Found a dual link dual break ... :-)
Make a good solder on SMD module (very difficult) after scattered and cleaning the SMD from the glue and replace the double wire with a 2 little wire of 0,1 mm.
Sealed all with a black silicon and remounted on car.
With VAG all is good, no fault code, no problem and test result is OK. Well, 1440 euro in my house.... :-)
Bosch you must revisited the costruction plane of this product. Too many defect and all for a VERY BAD wire, stressed under soldering in the manufacturing moment. You are crazy.
Bye to all and sorry for my poor english.

Yup, last thing.... UWE ROSS you make real GOOD software.
You are my hero. Fantastic...

Would LOVE pictures!
 

Buddy works on the Bosch silicon - he'd agree with all you said!

Yes..this is very interesting...try to do a write up with pictures and email it to me at assume_itzapungetit@yahoo.com

Maybe I can work up a tech article out of it..

Re: Would LOVE pictures! but...
 

no picture, sorry..
I have make all work under a great lens and, to make photo, need other 2 hands.... :-) .. and a Macro optical for my Fuji S1Pro.
The locations of the faulty wire was in the middle of the SMD module, down to the wire that go out in the outside connector.
I think that is a + Positive wire.
This wires was long as 8 mm and the distance from SMD point soldering to the connector was only 5 mm.
I have tryed now a little on my car and it is perfect.
I have removed the upper cover with a drill. Not with a screwdriver or a knife. Make many attention when open this cover. No part of iron, solder or any plastic little things must go inside.
Remain in waiting mode.. :-)
Bye to all.
