Hi everyone, does anyone have a schematic for the A 611 153 11 91 [Mercedes part number] / 0 281 011 747 [BOSCH part number] ECU, or know what signals go to the damaged pins of the connector?

You should be able to get a service technician manual and look for that area to be able to know what pins are affected by this burn out area
One note these manuals are not cheap but you have to go to the dealership to get them
Sometimes you can get just the electrical wiring diagrams from the dealership for free or for a fee at least in this countryLast edited by sam_sam_sam; 08-02-2022, 05:14 PM. -

I already have access to the car's electrical wiring as I used to work as a mechatic at Bosch. The pins are for the crankshaft, camshaft and the common rail pressure sensor if I remember correctly.
I was looking for the ECU's schematic because the signal lines are untraecable as they're routed on an internal layer and I wanted to solder a jumper wire to the connector to restore the damaged connection.Comment

If this board is more than 2 layers it will be very difficult to almost impossible to repair at least this has been my experienceComment

Hello, I search this connector (oxydated).
It's a fpc zif low profile connector. It come from camera sensor, it is very small : 0.3mm between 2 pins.
I ordered 2 from Aliexpress called « 0.3mm pitch » but one was 0.5mm between 2 pins and the other 0.6mm. In fact « 0.3mm pitch » seams to be the pad width and not the distance between 2 pins.
I can't find it. The other websites like mouser dont show the datasheet, and I can't check if it is 0.3mm between 2 pins ?
Do you know how to find this connector please ? What is the exact name for find it ?

Hi, I would like to share with you small modification to your Bosch tool 12V and 18V chargers.
You can use it for almost all Bosch chargers what I have seen, for example part numbers GAL 18V-20, GAL 18V-40, GAL 1880, GAL 18V-160, AL 1820, AL1115CV, AL1130CV.
Bosch (today also other brands using the same system like Wurth, Fein) does not care if you destroy your batteries, because they can sell you new ones. So the marketing is telling you only about speed of the charging, so you will not wait for your batteries to charge too long. Me as a customer want the tools and batteries...05-24-2024, 01:00 PM -
Hi Everyone. First official post so fingers crossed I conform and also manage to get photos to work.
So I am requesting some help from anyone who happens to have one of these motherboards to hand and perhaps a multimeter.
My board has a single row of header pins for all the front panel stuff (have seen others where they are grouped together differently so thats no help) and the two pins for the power on switch had been previously repaired and I am trying to make a better repair. There looks to be pad and trace damage and im happy to relocate the header pin/pins to...06-24-2024, 01:24 PM -
My Bosch NEXXT 500 dryer quit today, press start nothing happens and the start button just keeps blinking. Not cool. Reset the dryer, same thing.
Even so the buttons feel good, my problem was the start button smd tactile switch on the PCB. Cleaned the switch with alcohol followed with Deoxit and the sucker runs like a champ again.
I like these easy evening fixes!
