• B-Class W246
• CLS-Class W218
• SL Class W231 SL550 SL63 SL65
• W166
• W176
• W246
• W463
• W207
• W218
When try repair the NTG4.5 or NTG4.7 Head unit, can use the NTG4.5, NTG4.7 Test bench to connect the head unit and dispaly try to start the system on bench, check the head unit electric current. If no current or less than 0.3 amp, may need the power supply circuit.
If the electric current less than 1 amp, may the data crash in the emmc chip. NTG4.5 Head unit Multimedia with 1GB eMMC chip (TOSSP48 Package type). NTG4.7 Head unit Multimedia board with 2GB eMMC chip (BGA Package type).
To program this two types of the chip, we have an dedicated adapter to program them while they are on circuit board directly, No need desoldering remove the chip.
Another flash chip 2S9JL… Should also be programmed if the head unit not boot after programmed the emmc chip. this flash chip have to remove from the circuit board put into the sockets and programmed by programmer.

How to repair BMW F18 N52 Engine MSV90 DME BSD failure oil measurement not possible
How to repair BMW F18 N52 Engine MSV90 DME BSD failure oil measurement not possible
BMW N52 Engine MSV90 DME usually report error like oil measure not possible, fault code: CD9304- BSD communication fault. and the fault code can not be deleted.
First step is to check the cables, exclude to cables failure. measure the BSD data line voltage. If all the cables in good condition, check the DME.
If confirmed the DME failure, it can be repaired, not very complicated, a chip inside damaged. in this article we will introduce how to repair it
Better not open this ECU housing, because the glue is very tight, hard to open, drill a small hole on the back of the DME, the postion please refer the picture above, use a small Nozzle hot air gun to remove the chip – TJA1020, Should be very careful, Change a new chip, clean the dust, the seal this hole, this repair work is done.

How to repair Volkswagen ECU MED17.5 Motronic for 2.0T Engine
Per many friend request, Here I made the Volkswagen 2.0 T Engine BOSCH MED17.5 Motronic ECU repair guideline IC chip function illustration, it’s may help some friend to repair this ECU.
In many Case the ECU can be repair by change of the IC chips, hopefully it will make sense.

AUDI A6 Q5 ESL/ ELV Module J518 repair solution & repair kits
AUDI steer column Module – J518 is easy been damaged, it’s a common problem, when the J518 Module is failure, the following problems will occurred when insert the key:
- Steer column will not be unlocked;
- Car will not start;
- Dashboard can not be light up.
But the key can rotate normally.
Repair solutions:
- dismantle the J518 Module form the car, open it, use XPROG read the MCU, there are three kind of MCU Model exist:
Read both the flash and eeprom dump from the MCU and saved on desktop, the XPROG wiring diagram:
- Buy new MCU from www.u-obd.com, as the MCU is new and blank, use the XPROG write the dump been saved in the first step in to the new MCU, then solder back on the J518 circuit board.
- Change the Relays Model No: ACT512;
- Better change the micro switch and the ELV motor as well.
- If the J518 circuit board is burned or badly damaged, or don’t want to do time -comsuming soldering work, better change a new blank circuit board.
Attention: When change the MCU, Desoldering the MCU, please mind the small resistors beside the MCU, The hot air gun may damaged the resistor, please be carful.
if the MCU is totally damaged and can not read the dump out, ask some one to share a dump, after write into the new MCU or new blank circuit board, use device to do adapting work.
Thanks for reading! If you like it please share to more people in need.

SUBARU Forester Smart key adapting method for all key lost
SUBARU Forester Smart key adapting method for all key lost
Preface:
We all knows SUBARU spare parts is very expensive, all key lost will cost a lot, here we share the SUBARU Forester key
adapting method for all key lost.
Abstract:
SUBARU Smart key all key lost key adaption have two common methods:
1. Disassemble the SMT Main ECU, Use AD900 programmer to write data into Toyota smart key, it can directly start the car, No need adapting on the car again, but must use AD smart key.
2. Disassemble the SMT Main ECU, immobilizer(ESL/ELV), Write initialization data, then study the key on the car.
Here we share the second method, SUBARU Forester use 5290 smart key, Year 2013, No immobilizer, disassemble the SMT Main ECU and ELV Write initialization data and study the key.
Process:
1. Get the ELV(below steer column), disassemble the ELV module, find the 8 PIN EEPROM on the circuit board, Model No. : 93c46.
Desoldering the 93c46, use programmer and adapter read the data, make a backup first then change the code shown as below picture.
2. Disassemble the SMT Smart ECU(back side of the A column of the car), it’s appearance is the same as Toyota except the LOGO, disassemble the shell find the 8 PIN eeprom near the CPU, EEPROM Model No. : 93C86. Disassemble the 93c86, Write initialization data, assemble back to the car, if without error the dashboard could be light up.
Volkswagen 35xx instrument immo key adapting tutorials all key lost
Volkswagen 35xx instrument immo key adapting tutorials all key lost
Volkswagen 35xx instruments cluster immo(New Jetta, New Santana, Skoda, volkswagen family the fourth generation immo manufactured after year 2013 ) all key lost adapting is an acknowledged head burn problems, many people try and then failed, here I got a new method to solve this tough problem, adapting new cars for volkswagen NEC 35xx instrument cluster all key lost.
Abstract: because the volkswagen encrypt the 35xx instrument, result in the impossible to get the immo code from the eeprom without a key, when all key lost we can not adapting new key in term of the common methods. but we can get a alternative instrument cluster unencrypted sorts such as 24c32, 24c64(smart sort), via online adaption, let the volkswagen server write the original 35xx instrument cluster data into the alternative instrument cluster 24c32 or 24c64, Ok, when this steps is down, we can use common methods to adapting 24c32 or 24c64 all key lost, because the alternative instrument cluster unencrypted, we can treat it as common all key lost case, when adapting work of 24c32 or 24c64 instrument cluster is down, we shifting back the 35xx instrument, all is down.
Devices & software needed: 35xx test cables, VCDS, VVDI2 Or K518, CN900, ODIS;
Process:
1. Use VCDS select the 25th column – immobilizer, advanced identification, read the 35xx instrument keys ID, record the ID (take picture or write down on a paper)
2. Change the instrument cluster 24c32 or 24c64, use the ODIS software online adapting. Select 25th column – immobilizer, adapting immobilizer, stoped before adapting keys, ESC.
3. Common methods adapting new keys for 24c32 or 24c64 instruments all key lost, manually input the keys ID we record on the first step. Use VVDI2 and 35xx testing cables to adapting 24c32 or 24c64 instrument keys on bench, there will be 6 steps, 1 to 5 steps, we follow it’s notification.
4. The sixth step: VVDI2 click read immobilizer data, then the interface will display VIN, CS code, PIN code etc, all the key position is FFFFFFFF, Blank. input the keys ID manually into the first and second key position. then click write immobilizer data, the two original car key ID already been write into the eeprom.
6. change back the original 35xx instrument cluster directly, the two keys no need study, cause their ID is the same as ID in the 35xx instrument, no need study keys the car can start with the two keys.
