Hi guys, I have defective part, Y36 B1 but no idea what part this is. Fault was 5170.

No leaks, works fine in terms of going up and down and to the correct heights but complains on the dash.

I note on the C3 the pressure shows a consistent 35 bar which to me is a faulty sensor. Is this the part I need? Is it integrated into a valve block or perhaps the compressor?

I will run more tests on the C3 today and see if we can find anything but any advice appreciated.

Craig.

Never got a chance to play with the C3 today and now away with work for a week or so but any research/learning beforhand is greatly appreciated.

Y36b1 is the pressure sensor located within valve block Y36--part number 212 320 03 58---the valve block is located behind the R fog light---FYI there are a number of special tools required to properly remove\install the valve block.

 

Thanks Plutoe, exactly the info I was after. Id hoped it was a cheap serviceable item but the valve block isnt too expensive.

Thanks again,

Craig

 

Hi. i have the same problem, but in R Class
fault 5172 check component Y36b1 (AIRmatic pressure sensor)
win wdc25112332A119695
Does anyone knows what is the problem. Thanks

 

Plutoe was bang on with me and after replacing the main control block Ive had no issues.

Its quite straightforward to do, I didnt need special tools per say just a good tool kit with deep drive sockets and plenty extensions. Im sure its in the same place as the GL in the R, behind the front right bumper above the main compressor. Mine was easier to replace by removing the front bumper. I ordered the part online and costs me £240 ish. Saw cheaper ones as well but needed it in a hurry.

 

Thanks for the answer. Block valve was already replaced 2 month ago and compressor too so it is must be something else. Or i was thinking if block valve could be broken again in such a short time? ( it was also shock absorber exchanged a few days ago but I was driving withe broken for couple of weeks - could this lead to block valve to be broken again?) Thanks in advance for help.
