Audi dashboard instrument cluster OBC pixel failure repairs
*** spare parts for professionals and for DIY'ers ***
At several Volkswagen and Audi models including VW Bora, Passat, Sharan, and Audi A3 A4 A6 A8, it is quite common to have pixel failures on the big red LCD in the middle of the dashboard instrument cluster. The problem lies with the LCD that needs to be replaced to get the pixels back for good. Please find the pictures below of the LCD befpre and after replacement:
Audi A3 / A4 / A6, VW Sharan / Bora / Golf, Seat models :
The unit on the picture above is just one example for the wide range of units these LCD's were used for. The models are mainly VW, Audi, Seat, and Ford models. The common thing is the BIG RED fading LCD in the middle. Missing lines or coloumns, desapperaing LCD pixels (sometines getting worse when warmed up).
Important: These spedometers made either by Siemens VDO and Jaeger - the LCD in them are different. It's worth it to remove the speedometer from the dashboard and check if it has a VDO or a Jaeger sign on it. For VDO models, we sell both, original VDO and Cinese LCD's too, for the Jaeger models we have the Chinese version only.
Audi A4 / A8 up to 1996 - old Siemens VDO speedometer with big red LCD in the middle:
Audi A4 and A8 old models (up to 1996) were produced with a quite similar speedometer with the above mentioned newer A3 A4 A6 models, however the speedometer is an older variant. The pixture above shows an old Audi A8 models, but there are other A4 modles with the same ribbon cable. At this model the LCD pixel failure is also quite common, however this case you do not need to replace the complete LCD - a simle ribbon cable (flexible cable) replacement will do the job, and solve the dead / fading pixel problem.
Audi A6 speedometer background light problems - the BIG red LCD is completely dead:
The typical failure at this speedometer model is that the LCD seems to stop working. The rootcause is the background light problem, which is caused by the dead SGE2685 transformer.
Audi Concert car stereo system display pixel problem repairs:
LCD pixel problems on the display of the Audi Concert Radio's display is also very common - the ribbon cable replacement solves the problem for good. This cable is usable at those models which were assembled with "Zebra strip" too. The instructions booklet we send together with the cable will include the repair manual of the "radio uncontrollable volume problem repairs" too, which is also very typical at this model.
