In the MERCEDES service they wrote K47 relay needed to change. But the were wrong. There is no K47 as it seems. That is why I asked for your help. To tell me if there is K47. Nevertheless, it seems finally that they meant K40, but strange they wrote K47, there can t be suck mistakes in MERCEDES service. Now I fixed the multirelay, and there are no problems for 3 days now. Hope this is the case, and I finally found it. I will let you know if anything else occurs. Thank you!I thought she wanted to know where K40 was located, hence Starfinder suggestion.
I specified Box next to Battery to avoid left and right confusion
The mechanic guy obviously meant K40, but got it wrong, yes the Hex Binary was in jest, it is "currently relevant for me" humour that I thought those who know what I'm doing atm would appreciate, (hacking a VGS 2 so a 7G Tronic Transmission will work properly in my V8 R170)
Without proper diagnosis it would be a best / cheapish guess to chuck a Crank Position Sensor on it first, but you know me, I don't do parts darts (too often)
yes the service man took it off (i saw it) very easy to find and replace it or fix it, after you easily take it off. Thank you.That was my thinking @Rofa Cheap to sort, but we do know K40 failure is common.
And as said, needs to be a proper K40, not cheap internet copy as they can fail faster than oem, or not even work from day one.
K40 location, from the link I posted in number 3 (I love that link!)

One thing to bear in mind when looking at diagrams is there being right handed and left handed versions of the car. I 'think' this is for US/EU left version, but if it looks different, look on opposite side of the car.
No aggression in that post. As multiple suggestions had been made it simply made sense to wait for your feedback (which may have revealed further information that could make the suggestions that followed such a reply more accurate).I have looked at all the answers and it seems they helped a lot, thank you very much! There is no need to be aggressive.
thank you again for your GREAT GREAT help, because if it were not for you, I would not have known that this was the problem, and I must say that 4 years, when I had it for sometime (the car stopped) I found the answer in this forum, and I knew it since then. Then it stopped doing that, do not know why, and now 3 months ago, I have had it everytime I drove somewhere, very often, and I know that this was the case. I went in 5 different service shops, and they were totally unaware of this, despite the fact that I gave them the answer that it was the K40, they told me no, this cannot be it. But I was sure, that this was the fault, because you wrote it here. Then in the authorised dealer the found that this was it. An authorised dealer with the ideal diagnostic mechanism it the best at far! No unaware service people for me anymore. Thank you!he told me that almost all older cars in the MERCEDES have this relay that can be broken sometimes.
I am having this problem with my SLK R 170, 1999 series, and for the past 8 months the car stops while running, and then I must wait , 20 min till it starts again, or the most, 1 hour.
Today, I went to the authorised dealer in Greece, the best one we have, and he wrote that I need to change the K 47 multirelay.
Is that it? Does he mean the K40? Why did he say K47?
I saw here in the forum that the K40, is responsible for many functions, among then the engine control, which I think this is the problem, when overheated. The problems that you are reffering here, and which I have, point at the K40 relay.
I just wanted to know if he means the same relay, refferring to as K47 multirelay, but he means the K40.
I searched everywhere, there is no such thing as K47.
If I ask him he will not answer, so please if you can help me, in this. Is it the same?
Is there a specific code numper for all of them?
Where can I look this up?
thank you very much!
Hello! Unfortunately maybe bad noews. 2 and a 1/2 months ago, I asked you about this problem. Went to the most authorised dealer of MERCEDES BENZ in Greece and found out that I should replace K40, it is damaged the multi rele. They told me it would cost more than 500 euro, so I decided to fix it instead, as other repairmen told me.Appreciate folks trying to help, but Maria has not been back in 3 days.
As the problem was 'urgent' best guess is that it is being fixed at a garage.
I went to a repairman and he ressolded it.
Absolutely not, waste of time and money !!Do you think I should search for another good repaiman? What are your thoughts?
No way of knowing absolutely.So I ask you, can it be that he did not do sth right? Because first it worked,and now it made this again. Do you think I should search for another good repaiman? What are your thoughts?
Thank you guys! I really haven t thought of buying new one, since they said here they would charge me 500 euro. They even charge the placement, thought I saw it how easy I can replace it. I will definately search for a new one I think yes.Yesterday I saw the prices of new ones I can buy from abroad, and it was so amazing the differrnce from the dealer here. From 117 euro tll 175 for a brand new one. And the dealer charges almost 500 euro that is why I decided to fix it!
I will check the code and I will tell you exactly the Nr. Thank you so much about this!
