Hello All.

I'm having a serious problem with my e290 Mercedes Benz,When driving most times My ETS,ABS and Brake Lights comes on continuously,and when this happens the car works only on one gear making a humping noise,I have changed my brakes,serviced my gear box and even changed the brake light switch and this stills happen.

It's so irritating when all these lights comes on.

Any Help 2 solve this issues.

Do you have to diagnose the car first..?,

Maybe your gear reaches "limp home", do you serviced the gear..?,

oil may goes in the TCU, or conductor plate goes bad, need to inspect that well....??

zAYED WAT ARE THESES CODES..CAN U PUT ME THROUGH?

The codes are what is found when the car is connected to an electronic machine which reads all the sensors and can tell you what is wrong. A MB garage will have one.

Check your rear abs rings for a break. Check your MAF.

Hey Guys,

Have connected the vehicle to the electric machine..and d machine tells me that it is the Transmission computer control circuit / Electronic Transmission control that has the problem and i need 2 replace it.

But when we open the old Transmission control system,i found out that there was oil inside the box.I was just wondering how comes the oil entered the box.

How will I be able to get the part?..any suggestion of a web site.

Please help me out.

First, you have to replace the pilot spacer, then clean the TCU connectors to make sure no oil in them,

prefer if you can find a working used one,, there are "4" #s will work with you:-

"021 545 03 32" or "021 545 05 32" or "021 545 07 32" or "026 545 91 32"

ZAYED,

christian_foday

OK WILL REPLACE THE PILOT SPACER AND WILL ALSO FIND A WORKING USED ONE TCU...

Some one just told me that after doing all that i have 2 re program d car again..is it true?

christian_foday

then how will i know the year of my car...i have tried so hard knowing it.

No need to reprogram it, just a simple RESET will be done....

ZAYED,,
