zafira lcd panel replacement repair supplier

This was a very helpful posting, thank you. The Haynes manual starts with removing the steering wheel with airbag which seemed a ridiculous way to start when replacing a panel light so your photographic sequence showing that wasn’t necessary was just the encouragement I needed to get on with the job.

I had fitted a towing kit but the trailer flasher telltale built into the instrument panel wasn’t working and the odometer has always been very dim so I wanted to check the bulbs. One problem I had which I think is worth mentioning, is that on my 2004 UK Zafira one of the facia fixing screws is behind the ventilation louvres in the top left corner of the panel. That louvre assembly can not be removed as the right hand ones can so it is necessary to go between the flaps with the torx driver. Mine was part of a screwdriver set with torx bits which makes it a bit wider than a regular screwdriver. It fitted between the flaps all right but the screw was right behind the flap with the slider on and being a torx screw the driver had to be square on to it. I thought the flap was plastic and would flex a bit but it is metal and brittle. The spigot at the end of the flap snapped off so be warned that it is quite fragile and care needs to be taken. I bought a dedicated torx 20 driver for replacing the screw afterwards which has a thinner shaft and got around the problem.

For people wanting to buy replacement bulbs before starting work, there are four different types on my Zafira. The bulbs are built into plastic bayonet holders which are all the same size and shape but are different colours which indicate different wattages and shape of bulbs. The panel illumination is done by three 1.5W clear bulbs in fawn holders. The odometer is lit by a frosted flat topped 1.5W bulb in a white holder. The left and right indicator lights and the trailer warning light are 1.1W clear bulbs in orange holders, so three of them altogether. The clock unit is backlit by two 2W clear bulbs in green holders. There is space for a third bulb at the bottom of the unit which I presume would be used if the car had a trip computer fitted. All other warning lights are LEDs which are part of the printed circuit board.

Most car manufacturers, as well as BMW, work with an open system, i.e. the independent aftermarket can install a suitable replacement battery without having to reprogram the vehicle electronics. However, manufacturers such as Audi use a closed system and assign so-called BEM codes for original batteries and original replacement batteries. The independent aftermarket is not able to provide this kind of code for replacement batteries.

PS: In Volkswagen Group repair workshops (Audi, Seat, Skoda, VW), calibration takes place via a guided function of the online diagnostic and information system (ODIS Offboard Diagnostic Information System). Data such as the BEM code, serial number and nominal capacity of the new original replacement battery are entered. In this way, the energy management system knows immediately that a new battery has been installed. The Volkswagen Group is currently able to enter any 10-digit serial number. The VW serial number is used for tracking the battery and for warranty purposes.

If the system is open, this tool is used to register the new battery in the on-board computer. In a closed system, the newly purchased replacement battery can even be configured by vehicles with BEM. Furthermore, standard or manufacturer-specific error codes are generally read out of the system or deleted. This is even after a voltage interruption during battery replacement and if the on-board computer in the vehicle was without power.

Even with Audi models which, unlike other brands, always ask for a code when changing batteries, the Banner Battery Service Tool (BBST) can generate the Battery Energy Management code (BEM code), so that the battery change is registered properly and various functions are not restricted. The Banner Battery Service Tool (BBST) also has a system check that checks the complete charging system including battery and alternator and contains an integrated product finder to identify the appropriate replacement battery.

Conclusion: Purchasing and BEM coding an original replacement battery instead of a replacement battery from the independent aftermarket – which does not have BEM coding – has only one short-term advantage: that the complete functionality of all systems is immediately available. Please note: The battery reaches this functionality without a BEM code, usually also after some time and various „trigger events“ (impulses, signals, e.g. starts, cold starts, cycles).Basically, changing a start-stop battery poses no safety risk.

If a high-quality replacement battery is installed, even without entering a BEM code, there is no safety risk, there is no risk of overcharging of the newly installed replacement battery, there is no increased battery wear, and the vehicle electronics or other components are not damaged. Nowadays, multi-brand diagnostic tools, such as the Banner Battery Service Tool (BBST) can carry out this so-called initialisation step for numerous car brands.

For A6, A8 and Q7 models with battery energy management from model year 2003/04, from 2010 almost all models with battery energy management and start-stop function (ultra) require configuration. Installing an original battery or original replacement battery and BEM coding. Without configuration or by installing a replacement battery from the free aftermarket, this may cause restrictions in the functionality and increased battery wear due to incorrectly functioning shut-off stages.

If the negative terminal (-) of the battery was disconnected during repair work or battery replacement on a car equipped with ISG function, the battery sensor must be recalibrated after the work has been completed.

If the negative terminal (-) of the battery was disconnected during repair work or battery replacement on a car equipped with ISG function, the battery sensor must be recalibrated after the work has been completed.

With all start-stop models, a configuration process only has to take place if no voltage maintenance (e.g. Memory Saver) is used. Otherwise, initialisation of various systems (electric windows, steering angle sensor, sunroof, clock and audio, tyre pressure monitoring) may be required. If the car is equipped with an automatic start-stop system, this should also be initialised. This means that the start-stop function is always available immediately after battery replacement.

It is absolutely necessary to configure all Porsche models, otherwise the start-stop function is not ready for operation. Without configuration or by installing a replacement battery from the free aftermarket, this may cause restrictions in the functionality and increased battery wear due to incorrectly functioning shut-off stages.

On models with a start-stop system (Ecomotive), the control unit that monitors the battery must be reset using a diagnostic unit. Installing an original battery or original replacement battery and BEM coding. Without configuration or by installing a replacement battery from the free aftermarket, this may cause restrictions in the functionality and increased battery wear due to incorrectly functioning shut-off stages.

For models with a start-stop system (GreenLine), the control unit that monitors the battery must be reset using a diagnostic unit. Installing an original battery or original replacement battery and BEM coding. Without configuration or by installing a replacement battery from the free aftermarket, this may cause restrictions in the functionality and increased battery wear due to incorrectly functioning shut-off stages.

For vehicles with battery energy management, i.e. all models with start-stop technology (BlueMotion), the configuration of the new battery is relevant. Installing an original battery or original replacement battery and BEM coding. Without configuration or by installing a replacement battery from the free aftermarket, this may cause restrictions in the functionality and increased battery wear due to incorrectly functioning shut-off stages.

Electric windows:Ignition ON (i.e. the electronic instrument cluster lights up on the display), but the engine remains OFF. Lower the window completely on the driver"s side, then close the window completely again and keep the button pressed for approx. 2 seconds after closing. This initialisation should also take place if the fuse has been changed or the plug on the window switch has been removed (e.g. when removing the door panel without disconnecting the battery). Often the operating instructions do not mention that this should be repeated for the other windows. However, it is nevertheless recommended to repeat this procedure for all other windows.
