How to repair BMW F18 N52 Engine MSV90 DME BSD failure oil measurement not possible
BMW F18 5 series was commonly seen the failure, oil measure not possible, use the scanner or BMW diagnostic tool read the fault code is: 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, And it’ the Continental DME MSV90 common fault.
Should be very careful to open the ECU, I have to say this ECU shell is very tough to open, especially the back side, and very easy to damaged the inner circuit board. Most people damaged the inner board via open it, and the damage can not be repaired, so must be extremely careful and slowly with lots of patient.

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.
Gifts of rose, hand there are lingering fragrance.

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.
- dismantle the J518 Module form the car, open it, use XPROG read the MCU, there are three kind of MCU Model exist:
— MC9S12DG256CFUE OL01Y;
— MC9S12DG128CFUE 1L59W;
— MC9S12DG128CFU 3L40K;
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.

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.
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.
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.
-keep the Red marked code code the same, others all change to F, When dump revised, use programmer and adapter write back to 93c46 eeprom
, and solder back to the circuit board.
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.
3. Use Key programmer add new keys directly. Use K518
, or I80 key programmer, connect the car OBD interface, select SUBARU, then XV smart system, direct add new key, all down, after the keys added, no need sync, directly start the car.
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
, Ok, when this steps is down, we can use common methods to adapting 24c32
lost, because the alternative instrument cluster unencrypted, we can treat it as common all key
lost case, when adapting work of 24c32
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;
1. Use VCDS select the 25th column – immobilizer
, advanced identification, read the 35xx
ID, record the ID (take picture or write down on a paper)
3. Common methods adapting new keys for 24c32
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
5. Click generate the distributor keys: select the car brands and models, then select the OEM keys, select generate key
1 or key2
, then click generate distributor keys
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.
Note: for fear the ABS code lost, better get the ECU and instrument adapting on bench, recommend buy the dedicated 35xx test cables, no need adapting on the car, decrease the risk of code lost.
Need 24c32 or 24c64 instrument cluster, please contact: firstname.lastname@example.org
