1 Audi 8L A3 and B5 A4 ClrMFA Install Guide ClrMFA frm AutPilt. Instructins frm Clusters by Litke and pinut frm Drive2 This is an verview guide n hw t install the v3.2/v3.4 ClrMFA units int Audi 8L and B5 A4 VDO clusters. Thugh the 2 types f clusters appear very different, the fundamentals fr ClrMFA peratin and install are the same. This is a general step by step guide n hw t fit the unit. This will nt cver basics such as sldering techniques, r hw t disassemble the cluster. By Litke LLC and Matthew Litke are nt respnsible fr any damages yu may cause t yurself, yur cluster, r yur vehicle during this prcess. ClrMFA Kit Cntents: -Main PCB, LCD, 0.12mm^2 wire, 0.35mm^2 wire, SMD resistrs, beeper, matte film screen prtectr. Audi A3 8L Audi A4 B5

2 Tls/Parts Required: -Slder irn and slder. Slder wick is helpful but nt required. -Wire strippers and wire cutters -T10 Trx Driver -Needle nse pliers -Tweezers -Ruler/Tape measure -Knife/Razr blade -Dremel/Rtary tl -Duble Sided tape (3M s Red Very High Bnd wrks well) -Multimeter (t check wire cntinuity) -Drill (t twist the CANBus pairs) -Scissrs -Optinal: Glue t secure wires and PCB -Optinal: Heat Shrink Tubing

3 Install Steps Prepare ClrMFA PCB Cut the smaller gauge wire int 14 pieces in 100mm lengths each. Cut 11 mre pieces f the smaller gauge wire in 200mm lengths. Cut the larger gauge wire in 3 equal pieces f rughly 230mm lengths. Slder these cut wires t the ClrMFA PCB as shwn the diagram abve. Rute the wires thrugh the bttm f the PCB fr a cleaner lking install. The large gauge is fr Grund, 12V, and Ignitin. The 100mm pieces will be used the 2 beeper wires and all wires ging t the GRAY cnnectr. The 200mm pieces will be used fr wires ging t the GREEN and BLUE cnnectrs. Mark CAN High n bth Cmfrt and mtr with a marker than twist Mtr CAN H and L tgether with the drill and twist Cmfrt CAN H and L tgether. Attach duble sided tape t the backside f the PCB. Dubling up 2 pieces f 3M VHB prvides gd spacing between the cluster and ClrMFA PCBs and ensures the LCD wn t sit t high r t lw with regards t the face when installed. If yu dn t intend n glue the PCB later, use additinal duble sided tape at this step s the bard sits securely.

4 Cluster Disassembly Remve the lens. It is attached with 2 T10 screws (ne near the green plug and 1 near the blue plug) and 8 clips (2 n bttm, 4 n tp). B5 has an additinal hk n the left and right side f the husing. Remve back plastic husing. This is held nt the PCB with 1 hk n the far left and 1 hk n the far right. Remve the needles by twisting cunter clckwise while pulling up then remve faces. Remve the clck and dmeter screen cage by bending the hks and lifting them ut. Remve the white plastic light shrud. There are hks that need t be pressed n the backside f the PCB t release it. The dmeter reset knb will als need t be pressed thrugh the PCB by pushing in the hks n it and feeding it thrugh. Prepare cluster PCB fr ClrMFA Start by remving the stck screen by remving the metal cage arund the screen (sme d nt have this) then un-sldering the ribbn cable. Make sure t clean up the slder pads after the screen is remved s that nne f them are shrting tgether.

5 The 2-wire sensr and the plastic husing/shrud needs remved. Remve the LCD husing (2 large metal pins. Heat with slder while pulling the husing ff the PCB) then lcated the 2 pads fr the sensr and heat thse up while pulling the sensr cable ff. Remve all the LED s riginally behind the LCD. These LEDs d nt require jumper resistrs. Leave them pen. Ensure slder is nt bridging any f the pads tgether.

6 Cut the traces fr pin 17, 18, and 19 n the gray plug fr the factry menu cntrls. Fitting ClrMFA t cluster Remve the duble-sided tape backing and press the ClrMFA bard t the cluster. The large dide at the tp f the bard shuld be centered with the high beam LED(s). Leave abut a 3-4mm gap between the bttm f the bard and the cluster PCB. D nt have the edges f the tw be flush with ne anther f the screen will sit t lw and the bttm f the screen will be cvered up when the lens is installed.

7 Begin identifying where each wire will g and rute it s that it runs alng the tp f the clck/dmeter screen area. Cut the wire t prper length (extra wire can be tucked under the ClrMFA PCB is yu want t errr n the side f cautin). Begin sldering each wire t it s crrespnding pin n the blue, green, and gray headers. Since the wires are expsed and easy t fllw, yu can g ne wire at a time and fllw the pinut chart n the abve r can use a multimeter t identify each wire t ensure everything is cnnected crrectly. Rute the 2 remaining wires fr the beeper thrugh the pening next t the stck LCD slder pads and slder them t the beeper. The lnger leg f the beeper is psitive. Add heat shrink t these slder jints. D 1 final check with the meter t ensure each wire frm the ClrMFA bard is in the crrect lcatin. The slder prtin is nw cmplete.

8 Reassembly Cut the clck and dmeter LCDs ut frm the rest f the light shruds and attach these t the cluster PCB. Secure all the wires with tape, epxy, ht glue, etc s that they d nt chaff and cause accidental shrts. Can als secure the ClrMFA PCB better at this time just ensure the bard is sitting straight and level.

9 Lcate where yu d like the USB B t g. Cutting a square hle next t the gray cnnectr is an ptin. Glue the prt s the lcatin yu chse. Use a rtary tl t trim an pening in the white plastic shrud t fit the ClrMFA screen. It is necessary t cut ut rughly half f the high beam icn area and flatten ut the rund psts n either side. Cut ff the high beam alignment pin.

10 Cut the matte screen prtectr film t the size f the LCD and apply it t the LCD. Additinally, it s nt a bad idea t apply a small piece f black electrical tape t the tp area where the screen cvers up the high beam icn. This will prevent any LCD light bleeding thrugh the high beam icn at night. Install the white plastic shruding and dmeter reset knb. Ensure it fully sits nt the PCB and isn t being lifted up by wires.

11 Install the ClrMFA screen nt the ClrMFA PCB. It s recmmended t add abut 3 layers f the duble sided tape t hld the screen and bard securely tgether. D nt stack t much tape thugh that it causes the screen t site abve the white plastic and thus wuld cause the faces t nt sit flush. Install faces and needles. When installing the needles be sure t nly turn cunter clckwise s the mtr zers ut then keep turning until yu reach 0. If yu pass 0, g all the way arund again and start ver. Never turn clckwise. Als leave abut a 2mm gap between the bttm f the needle and the face s that it des nt rub and catch. If VCDS is available, the needles can be checked with 17-Instruments and utput tests which will result in the needles sweeping and stpping at 3000 RPM, 190* (r 90* n metric), ½ tank, 62MPH and n B5 250* il temp and 12V. If the needle is ff during these tests t NOT mve them while still in the test, click next s the needle ges back t zer then mve it. Snap the lens back tgether and reinstall the 2 T10 screws. Install cmplete.

12 Ntes: Fr use f the bst gauge functin n the ClrMFA, the MAP sensr must be splice int and run t the Gray cluster plug cavity 32 (will be unppulated). If the car is nt factry turb, a 5V MAP sensr can still be used and return signal run t Gray cnnectr cavity 32. Cnnect t ECU T121/101 fr Gas, T121/71 fr TDI. Be sure t adjust the gear ratis in the calibratin settings s that the indicatr wrks crrectly. A step by step guide has been made fr that as well and can be prvided.
