Black screen, sound still there
The unit works (you can hear the sound) but the display stays black or flickers. Typical LCD or backlight fault: we replace the panel, everything else stays original.
The dealer tells you to replace the whole unit: almost always it is a single component.
We repair infotainment units at component level: MIB1 · MIB2 · MIB2.5 · MIB3 from Volkswagen, Audi, Škoda, SEAT, Porsche and Lamborghini, along with instrument clusters, gear selectors and eCall control units. VIN and configuration stay untouched: no recoding.
Coding, SVM, datasets and Plug&Play units are separate services, for those who ask for them. Below you will find yours: select the vehicle to see which units it can take, or search by the part number printed on the label (e.g. 5G0 035 842).
Can't find your model? Message us on WhatsApp: we reply the same day.
You will find it in the vehicle registration document, field E, or on the plate in the engine bay.
You will find it on the unit label (the unit has to be removed) or on the dealer invoice.
These are the six faults we see every day. Each has a precise cause — and almost always a repair, without replacing the unit or losing the coding.
The unit works (you can hear the sound) but the display stays black or flickers. Typical LCD or backlight fault: we replace the panel, everything else stays original.
The radio restarts by itself in an endless loop. On MIB2 it is almost always worn eMMC: we replace it with higher-grade memory and rebuild the firmware.
The display shows an image but the touch does not respond, or "presses by itself". We replace the digitizer keeping the original panel where possible, with bench recalibration.
Amplifier in protection, muted channels, hiss. We work on the audio stage and the converters, bringing the sound back to factory specification.
The navigation does not lock onto the satellites or the map stays still. We repair the GNSS module and check the antenna chain with a signal simulator.
No sign of life, the vehicle does not detect it. We analyse the power supply and the CAN/MOST bus from the input stages. You know what is wrong with it and what it will cost before you decide.

We do not work "on MIB units" in general: each platform has its own supplier, its own firmware and its own typical faults. These are the systems we actually work on, with what we hold in the archive for each of them.
We handle the faults at component level on all of them: worn eMMC and boot loops, display and touch, audio stage, GPS and radio modules. Search the archive →
We do not swap whole boards: we work under the microscope on the individual component. BGA stations for memory reballing, microsoldering, test benches with vehicle simulator.
Every unit arrives with its own history: after the diagnosis we work only where it is needed, from the hardware to the configuration on the vehicle.
Golf 7/7.5/8 · Passat B8 · Tiguan II · Polo AW · T-Roc · A3 8V · Q2 · Octavia III/IV · Superb III · Karoq · Leon 5F · Ateca · Formentor and others. Can't find your code? Ask us: the part number is printed on the unit label.
Each service has its own page, with the typical faults, the turnaround times and what to expect.
Email or WhatsApp: the car model and what the unit does. We reply the same day with a preliminary assessment.
Partner courier with a prepaid label, or your own courier. Packing instructions included.
Bench analysis with vehicle simulator. Detailed quote, free of charge: if you do not accept, the unit comes back to you.
Component-level repair and full bench testing: display, touch, audio, GPS, radio.
We send the unit back with the service report: fault found, work carried out, test result. 12-month warranty.
Can be bought directly online: diagnosis, testing, SVM parameterisation and component protection included.
Discover Pro on the Golf stuck in a boot loop. Diagnosis the same day, repaired and sent back within 48 hours: refitted and everything works, navigation included. No coding at the dealer.
Black screen on the Passat, the dealer wanted €1,800 for a new unit. Here I paid a fraction of that and kept my own unit with all its settings. Professional and clear about timings.
I run a workshop and I send them all my customers' MIB units: a technical report on every job and never a warranty return. The kind of supplier you would want for everything.

The diagnosis is always free. After the analysis we send a detailed quote: you only pay if you accept the repair. The cost depends on the fault, but on average it is 20-30% of the price of a new unit.
No. We repair your original unit: component protection, coding and navigation stay untouched. You refit it and it works straight away, with no trip to the dealer.
In most cases 24-48 working hours from receipt of the unit, plus shipping time.
All repairs are covered by a 12-month warranty on the fault repaired. If the problem comes back, the second job is on us.
