You sir are a legend. This fix cost me $17 AUD. And was so easy to fix with your tutorial. I'd just been idling my car for 30 minutes every time I drive to get the SRS fault to clear. And dont get me started on unexpected weather. I nearly have accidents due to my windshield vision going when it rains because i have to go to work but can't afford a mechanic. Thankyou so so much.
You are a star! Mine had the same issue and I replaced the relay using this video otherwise it would have been impossible to do it otherwise. All for less than 20 GBP. Thanks again
Thank you. I had exactly the same problem with my C Class Coupe. Your video led me to research which relay was the problem with my car. It is easier to get to as it's in the engine compartment. Same realay and £20 from Mercedes. Fixed in less than 5 minutes. Thanks again.
Thank you very much... Same problem with my 2009 B class and now its fixed... SRS alarm gone and wipers (front and back) are now working! Thanks again from Cyprus!
Have to say a big thanks for this video. Last Sunday morning I got the SRS malfunction message and instantly thought that it was going to be a lot of time and $$$ to get the car serviced even though I need to sell the car in 2 months due to an overseas move. I ordered a relay for $28 Canadian and yesterday it arrived. It was pretty easy to install and the problem was solved. Thanks for taking the time.
Please help me. The tachometer of our B-Class W245 car, made in 2005, is lying. Sometimes it shows more, sometimes less, but sometimes it stays at zero and does not move. Where should I look for the reason why hpol is showing so much and so much? What could be the most likely reason. Possibly a soldering error? Or could a contact be faulty? Thank you very much in advance for your kind help! Best regards, János bohus
thanks a lot. i bought a b200 2008 model and it gave me the error after years of using it and i thought it will cost me a lot of work . Love from South Africa
Hi, similar problem on my A170 2003. Front windshield washer doesn't work and the same SRS light is on, till this video I never thought that those 2 problems are maybe connected. How did you found where that relay is located? Thank you.
I spent a long time on Google and finally found a post on Mercedes-Benz Enthusiast Club Singapore's forums. I think the post is no longer there but it mentioned the wipers & SRS and the relay, and where to find it. I just created a video to spread the info. :) The fuse sheet and manual will tell you where the relays are. On a UK A160 I know the relays are in the same location, under the carpet in front of the passenger seat.
@@iloveimageprocessing Thanks, it is, I'll inspect that relay as soon as I can. If it works, I'll buy you a beer. :) Thank you for video, found it very helpful.
Hello Dude ! Thank you very much for your video ! You boy help me a lot ! I got the same problem with our B180 NGT/ I do all exactly the same like u and now the problem is gone

Thank you for this video. The SRS warning light came on my Dad B170 yesterday... and didn't relise the wipers stop working too. :( gonna have to check that out.
I have a A160 2011 and I am pretty sure the relay is in the same location, but I am not sure if it is the same relay. That said my B160 and A160 were similar in lots of ways. Also another commentor said that to clear the error after replacing the relay on the A-Class still required them to go to a Merc dealer. My advice would be to go carefully and locate the relay for the SRS circuit (read the manual / fuse sheet to locate the correct one). If you are handy with the multimeter you can check easily if it has failed. While you are there, check the relevant fuses etc. I'm not MB trained, just own a few Mercs. Only do what you are comfortable doing! Good luck.
Pls I just got a mercedes 230 2006 had for 2wks and went to drive it today and Rough idle and very sluggish can seem to get us to badly excerpte check engine lgt on and it has had the srs thing on sense i got it but it is now also say eps one is on now to what's wrong with it
Have an srs malfunction on our b150 class but wiper blades are working fine so how would I fix this problem? Is the process still the same? I haven't checked under the carpet yet where all the switches are but if the fault is not there do I have to go through this process?
I honestly don't know, but my personal view would be to go through the steps slowly and then use a multi-meter on the relay and see. I'm not a mechanic just a person with a dislike for spending lots at a garage! I couldn't say if a B150 had a different setup for the wiper circuit, but it is possible. Good luck!
Sometimes it is the seat cable tahtn connects the seat and the bode underneath the seat. From moving the seat it breaks the cable insulation which means resistance goes up and down willy nilly and the airbag SRS goes off 🎉🎉🎉🎉🎉
@@iloveimageprocessingB150 is B160 with older software just less power same engine 1:1 the same 😅 Wiring should be equal at same trim level. Yours has some options I have seen but nothing mayor 😂
Thank you very much! I had a bad battery removed, and SRS light went on. In Germany I cannt get through the tech inspection. So, how was you sure that it was this relay?
I was not sure, but I felt like trying it. You could remove the relay and test with a multi-meter? Some people say that the SRS Fault (once fixed) requires a MB tech person to clear the fault. That was not the case on my B160 as once I cleared it from the steering wheel it was gone forever, but I don't doubt what people say. The question is do the other faults exist as well (light on the passenger sun visor and the wipers)? If they do, then it sounds like the same issue. If the wipers work then maybe it is just a fault code that needs clearing and if it keeps coming back when you do it, then go to MB I guess. Good luck!
@@iloveimageprocessing😊🤸♀️thank you very much for answering so quickly! My front whipes are working. I dont have the white lamps above the front window as you do. My new Mathies battry went flat. It took 5 times to go flat, when technical support ADAC believed that it was the new battery and not smth else. So since then SRS light is on the display. All the rest functions. When the defect battery was removed, the red swicht got disconnected. So ADAC technician explained the SRS light to be resulting from the disconnected red swicht under the driver's seat. When I came to the workshop, they connected the switch, but the SRS message kept lightning. The workshop read the mistake out and explained that "someone is sitting on the front passanger seat". They tried today the whole day, but couldnt get read of the SRS light. Then I found you video!😊🌹🤸♀️💃 Thats why Im asking- how did you realized, that it was this relay B? Or any other relay?

@@pininfarinarossa8112 I know, MB are expensive here as well, and some are not any good either. That's why I spent so long looking for the answer before going there. Unbelievable that the workshop could not solve it. That is terrible. I did read about the seat sensor, and I read it is complex and not a simple on/off sensor, but a communicating signal. I think I decided not to investigate more with the seat sensor because I decided I would not be able to fix something that complex. I found a comment online about the relay and so I took a gamble and went there to investigate. It was a guess/gamble really, not based on anything exact.
I have a Mercedes’ c280 elegance 3.0 steering wheel is on the left, I have spent so much time looking for the cause, didn’t want to take to Mercedes dealership because it would cost a fortune, 3 days ago I took to an electric mechanic, after I left the car there he called me 3 hours later, he said he believed the problem was the fuel inyectores and he could finish the job by end of the day, he charged quite a bit of money, I would say equivalent to 250 US dollars, I don’t have a job now and it was a lot for me.

I got the SRS light on after fueling up few mornings ago. Does it has anything to do with it? Strange thing is that there is no malfunction error message display on the center. Any idea?
Under the seat is a red connection box that connects the seat sensors. It might be that, and the SRS light is saying the passenger airbags are disabled because it thinks a child seat is present. Unfortunately I heard that the electronics in that is quite complex, more than just a few wires and that it sends coded signals. It could be just loose wires so check, but anything more I think you should get fixed properly - the passengers life might depend on it! Good luck!
jtcber . I have the same SRS fault as yourself. The guy here was very lucky imo, because his problem with the main display also showing SRS along with the red SRS light coukd equally have been the passenger seat pad, which is a pain to DIY. He was also very lucky in seemingly, he didnt need a diagnostic reader to reset his SRS display error, which is the norm for any display error code. Back to my problem, and one you have hopefully solved? Unlike this video, there is no SRS 'Go to Workshop' on the display, just the red SRS light.....and, like yourself, no seat belt warning chime when driving without belt on. This logically points to the seat belt anchor, but when I disconnected the red terminal block under the driver seat, and measured the resistance of the seat belt anchor two pin plug, it measured about right, ie. open circuit seatbelt unconnected, and just over 120 ohms or so seat belt connected. I am wondering if there is a fuse for the seat belt connection/warning chime but cannot find one in the main fuse block. Sods law says it will be one of the relays where this guy here accessed at not small hassle. So far, according to Google searches and Mercedes forums, I have found the design and general reliability of these B classes to be simply appalling. A Ford C max would have been better designed and more reliable, I suspect. But, I digress lol....did you manage to solve your problem with a replacement seat belt anchor latch?

Initially I Googled for the fault and read various forums. I think first I did look at the pressure sensor, wiggled the wires, checked for lose cables etc. with no luck. When I replaced the relay (following reading a post from someone with the same issues and who fixed it with a new relay) I did not know if it would work. It was just a gamble. I also gambled on a diagnostic port to USB reader for the car, but I never used it once I realised that MB have their own hidden menus. So it wasn't all win-win. The stories of the pressure sensor being a protocol driven unit rather than an open/close switch scared me enough to not bother opening it up. Luckily I cleared the SRS fault message from the console, but I could well believe the need for trips to the dealer. Maybe the fault code is still in there! I don't have the B160 anymore, I upgraded to a newer GLA. The location of the relay (in the SAM hidden under the carpet and hard to reach) is a good example of the bad design I agree. But the new GLA has it under an 'easy to pull up' carpet. Better but not wonderful. As nice as the new car is, I miss the B160 a lot. Part-exchanging it was like loosing a family member. I kid you not. It was a sad moment. The GLA is great, but not as well sound proofed and viability from inside is limited by a massive central pillar and smaller windows. Trust your purchase, the B-class is a nice car!

Initially I Googled for the fault and read various forums. I think first I did look at the pressure sensor, wiggled the wires, checked for lose cables etc. with no luck. When I replaced the relay (following reading a post from someone with the same issues and who fixed it with a new relay) I did not know if it would work. It was just a gamble. I also gambled on a diagnostic port to USB reader for the car, but I never used it once I realised that MB have their own hidden menus. So it wasn't all win-win. The stories of the pressure sensor being a protocol driven unit rather than an open/close switch scared me enough to not bother opening it up. Luckily I cleared the SRS fault message from the console, but I could well believe the need for trips to the dealer. Maybe the fault code is still in there!
I don't have the B160 anymore, I upgraded to a newer GLA. The location of the relay (in the SAM hidden under the carpet and hard to reach) is a good example of the bad design I agree. But the new GLA has it under an 'easy to pull up' carpet. Better but not wonderful. As nice as the new car is, I miss the B160 a lot. Part-exchanging it was like loosing a family member. I kid you not. It was a sad moment. The GLA is great, but not as well sound proofed and viability from inside is limited by a massive central pillar and smaller windows. Trust your purchase, the B-class is a nice car!
