Audi A3, VW: Repairing Yaw Rate Sensor G202 - Soldering Guidelines & Part Number 1J0907657B

Hey
Recently I have damaged the yaw sensor g202 in the Audi A3 - the error was described as impusable signal.
I read a little on the Internet that these sensors have a weakness in the form of weak solders. What could have been warmed up again - but it seems to me that in 2002 hard automotive February was already used - although from what I remember the ROHS directive came in about 2005/6.

Auction portals offer ads for repairing the sensor - I suppose it is a porridge with milk - just can anyone share what needs to be done / replaced / can I sell everything by some solder paste? On the English forum I found a description that you should solder out and re-solder the 8 pin chip. There are 2 such chips - but why not just warm it up?

Plan B
Does buying a sensor from disassembly have his Part number identical? I found 2 pieces on the back but the numbers were slightly different. For me it is 1J0907657B

Grandfather is terribly expensive - no one will help?

Nitro dissolve this mass, ditch, unbone the pins of the socket, and then when you break off the plate it will turn out that this integrated sensor is soldered. you sold it back and played. chance of success 25%.

damdam, it seems to me that you had another sensor in mind.
My looks in the middle like this:

This tile is held by rubber bands. Can there still be a scalpel underneath which you need to sell off?

Do not you have these alu wire braids? - most often it breaks.

I moved them lightly - they are all ...

Colleagues, I also have a problem with this sensor - the designation 1J0907637B (there is still the second sticker 1J1907637B on it). Do these alu-wires have to be so thin? If I soldered a copper cable there, it would be more reliable, I just do not know what about the vibrations (so that the sensors will not go crazy). What does the tile look like from the other side - did anyone see? I would not like to pick those glued gums - if it turned out that there is nothing to look at ...

people who know how to fix it do not want to share because it's a piece of a good penny. I managed to buy the second one ... luckily, the guy did not know what he was selling and it went at an incredibly low price. I recommend going for a shred with an item in your hand and look for such a "relay".
I asked in a nearby Czech store - price per PLN - 2550PLN.

As for the wires - they have to be so thin because the whole plate is hanging on elastics - the wires can not stiffen the structure.

I say yes, you have to feel it to assess whether it is a wire, soldering requires practice, here we do not share knowledge because the group szmelcvagen is described only practice is needed ...

In that case, if "szmelvagen group is described", please indicate where you can find information on the structure of this sensor (DTR or schematic)?
A friend, perhaps, only fueled his hostility towards the VAG group's car users (and perhaps he has built up his ego)? I am asking for particulars, not a blank translation, that "you have to feel it"!

I've got a trash myself and found a description on the web, now I associate it next to the sensor. Nothing wires need to be gently from side to side and I used to go one more than others. He did not break it out. He helped me. Thanks to the practice of soldering, unfortunately.

If so, let it be a trivial matter.
Show off whether it worked.

A colleague of Jap was more concerned with the description of the repair of the G200 lateral acceleration sensor. There is an 8-pin long-drawn chip and they often leave February - the "advantages" of unleaded tin ..
In the described sensor G202 Yaw Rate Sensor are scalpers (2 pcs 8-pin, 1 piece 24-pin, 2 pcs 28-pin, 3 pcs transistors and passive elements) and are surface soldered. In my opinion, due to the suspension of the whole plate absorbed by the silicone suspension, cold solders from vibrations should be expected here.

I removed the plate from the casing, disassembled the screen, if it interests someone - I can send photos.

I wonder only if the computer reports a fault related to the errors from this sensor (G202), does it not affect, for example, incorrect signaling from the steering angle sensor? Does anyone know what symbol has the sensor at the steering wheel and does it communicate directly with the computer on its own "behalf"?

when it comes to the steering angle sensor, he is in the so-called sliding ring "retractor" under the steering wheel ...
There are several types depending on the equipment eg tiptronic, mulifunction ...
nevertheless, let's call it the usual version from ABS and ESP are: 1J0959654AG
which in turn was replaced by the Newer in 06.2012. at: 1J0959654BK
as to the transmission of signals it depends again on the equipment,
because if you have a multifunction steering wheel driver, the signals pass through him ...

It's not that I want to get rid of but such a "burial" in active systems and this yet
from the control of the security system which is ABS, ESP; is Very Dangerous ...

even if you manage to "somehow" fix it, what is your confidence that this sensor will work correcting? ..
if the ESP security system will receive signals that are correct on the electrical side
but they have nothing to do with the actual state, and such can send the sensor being repaired is probably
Nothing more needs to be written ... at a higher speed, not much can be done if the ESP will correct something
which has nothing to do with the actual situation on the road ...

if right after turning the ignition switch this error appears, the fault is electric strikte ... eg "cold" solder
or what happens very often; damaged electrical installation ...
but if the system recognizes a mistake only after defeating a distance, it may indicate an internal error
damage to this sensor ...

anyway...
if you are sure that the fault lies on the sensor side (not the installation)
the only sensible solution is to buy a new or functional stimulant ...
so much my advice ... of course you will do as you please ...

nice...

As for the active security system, I agree, you should not dig too much. My observations concern the situation where during normal driving (especially when starting from a petrol station, or normally on the road on a straight road), the brake of one wheel begins to grind and the car not only loses speed, it is a real chance of an unexpected change of direction This is an unreasonable operation of the ESP system and is confirmed by an error read by VAG (01542 - Angular acceleration sensor (G202)).
A few years ago I also had a problem with ESP, but then I got the wrong signals from the G200 lateral acceleration sensor and coped with it by blasting the sensor with old tin (with lead) - a method commonly adopted as effective.
Therefore, I hoped that this time the "damage" of the sensor consists either in the loss of any of the solder connections in the sensor or incorrect indication of the element that works with the sensor, eg the steering angle sensor (although this supposedly has its symbol - probably G85 and in total he should report directly to the computer if he was down ..).
At the moment I am on the stage of making connections on the smt sensor G202 and after Sunday I will try to test it, did anything help (because it probably will not hurt and it is not an intervention in the active security system, let's call it a factory condition).

Hello! I have a similar problem with error 01542. Kolego Thimo helped bailing ??

Sorry but no.. The problem lies somewhere in the "right" element of the sensor that carries angular acceleration by nature. I bet that this metal "capsule", which you can see when you open the lid (the picture somewhere fade, I'll look again).
For the curious, I am sending you a plate in the back (the side that you can not see after opening the sensor's lid).

Has a separate group in measuring blocks. I exclude an associated error

and what did the subject matter solve? where is the problem?

After the last batching, he does not throw an error, but he activates with light arcs. I will try again
