Are pixels, lines or letters missing from the instrument cluster display in your Audi A6 or S6 4B (C5)? If warning messages and trip-computer information are unreadable, the entire cluster may not need replacing. On a compatible unit with an LCD fault, replacing the display can restore readability.
Choosing the right version is essential: large FIS or small MFA, analogue or digital clock and instrument cluster manufacturer determine the correct repair or spare part. At Pixelfehler Hamburg, you can book a cluster repair or buy an LCD for a skilled DIY replacement.

Common Audi A6 4B C5 pixel faults
Typical FIS or MFA display symptoms include:
- Individual pixels, lines or whole areas of the display are missing.
- Letters and warning messages are only partly readable.
- The display becomes harder to read when warm.
- The image shows stripes or faded characters.
If gauges also fail, the lighting flickers or the whole cluster switches off intermittently, this may be a separate fault. An LCD replacement will not necessarily fix those problems.
Large FIS or small MFA – which repair is right?
The large driver information system (FIS) displays trip computer information and warnings. Smaller MFA / Half-FIS versions differ in display size and electronics, so the repair services are not interchangeable.
- Large FIS with missing pixels: Audi A6/S6 4B C5 FIS display repair
- Small MFA display with pixel faults: Audi A6/S6 4B C5 MFA display repair
Both services are intended for compatible A6/S6 4B C5 instrument clusters. If you own a different Audi A6 generation, check its own repair listing. A photo of your illuminated dashboard can help us identify the right option.
DIY Audi A6 FIS display replacement: check the clock type
We offer replacement LCDs for experienced electronics technicians. For the full FIS version, the clock design is especially important:
- Audi A6/S6 4B premium FIS LCD – digital clock version
- Audi A6/S6 4B premium FIS LCD – analogue clock version
- Audi A6 small MFA / Half-FIS LCD for compatible Jaeger/Magneti Marelli clusters
Do not buy based only on the name “Audi A6”. Compare display size, clock type, instrument manufacturer and compatibility notes on the product page. An incompatible LCD cannot simply be made to fit by soldering. Installation requires suitable tools and experience with delicate electronics.

Gauge failure or complete cluster problems
Incorrect speedometer, rev counter, fuel or temperature readings are not typical LCD-only pixel faults. The same applies to flickering illumination or recurring complete failures.
Choose the service based on actual symptoms. If there are several problems, contact us before ordering so we can recommend the correct scope.
Why repair the original Audi cluster?
Where repair is possible, your original instrument cluster is retained. This may avoid finding and adapting a replacement unit and reduces electronic waste. Whether any additional programming is necessary depends on the exact repair; we cannot promise the same result for every type of fault.
For Audi TT 8N FIS or gauge faults, see our separate guide. TT parts are not automatically compatible with A6 clusters.

Audi A6 4B C5 pixel repair – FAQ
Must the entire cluster be replaced when pixels are missing?
Not necessarily. A suitable unit with a repairable LCD fault may only need the display replaced. Additional faults can require different repairs.
Are the FIS displays for analogue and digital clocks the same?
No. Different replacement LCDs are offered for these versions. Check the compatibility information carefully.
Is an MFA repair the same as a FIS repair?
No. The small MFA and full FIS display have separate repair services. A photo can help identify the correct one.
Can you fix gauge faults or flickering illumination?
We offer additional repair services and a technical overhaul. These issues are not automatically covered by an LCD-only repair.
Can I bring my Audi to you?
No. We repair removed instrument clusters sent by mail only.
