Good morning All from the West Desert USA. I noticed there is some potential misinformation regarding the K1600 firing order. Can someone please nail it down with some firm clarification? My Gs911 says my #2 coil has a fault. I replaced all 6 coils jan 2022. Maybe I just got a bad lemon. Anyway "I Think" the #2 coil is cylinder #5? So sitting on the k1600 facing forward is cylinder #5 the 5th one counting left to right? So...."I think" the k1600 cylinders are (from left to right sitting on the bike facing forward) 1, 2, 3, 4, 5, 6 but eh coil firing order is 1, 5, 3 6, 2, 4???? So if my GS911 say coil #2 is bad then it is located on cylinder #5 correct? Sounds like one of my college math classes.

Don't know if this helps but the BMW RSD says to check valve clearance by setting TDC in order of 1,5,3,6,2,4 and numbers the cylinders 1-6 L-R facing forward.

Thanks GS Jim. I just needed some hand holding before I drain the radiator for the third time and swap out coils. It thanks me 8 hours and my back reminds me weeks later. it is easy work but just a crunch position without a lift

"So if my GS911 say coil #2 is bad then it is located on cylinder #5 correct? "
Hello
No, I don't think so. Don't overelaborate it 8) Sometimes german engineers make it easy.
Coil #2 works for cylinder #2
-
Could always try disconnecting a coil and see how it shows up on the GS 911 or move the suspect coil around and see if the problem moves with it. Much easier with the R1200 although left is 2 and right is 1, so never assume you you know how those wily germans are thinking😂
-
Thanks for the suggestion. I am not sure if the GS 911 will pick up the fault if the bike is not physically running? worth a try. I just dread draining the radiator again...such a freaking mess even with plastic and cardboard laid out. The rest of the disassembly is enjoyable to me.
-
ok, I have the radiator out, ready to change out coil. Now My gs911 says coil #2 and coil#4 are bad. My issue is: the GS911 say coil #4 s the 6th in firing order? It is obviously NOt the 6th i firing order...The german's must mean Cylinder #6????? any input would be amazing PLEASE. Coil #2 the GS =9aa says it is Cylinder #5 so that is easy

2012 k1600 with 100,000 US Miles: What a long freaking day. Here is what i learned from coil troubleshooting: noticed there is some potential misinformation regarding the K1600 firing order on the GS911 readout. The k1600 cylinders are (from left to right sitting on the bike facing forward) 1, 2, 3, 4, 5, 6. The coil firing order is 1, 5, 3, 6, 2, 4 . here is the issue. The GS911 Coil to Cylinder translation is not so clear. I am not sure if this firing order is the same for all k1600 but mine goes as follows:
Cylinder #1 coil fires 1
Cylinder #2 coil fires 5
Cylinder #3 coil fires 3
Cylinder #4 coil fires 6 GS911 reads "coil #4 is the 6th in firing order"
Cylinder #5 coil fires 2
Cylinder #6 coil fires 4 GS911 reads "coil #6 is the 4th in firing order"
Sooooo dozens of hours later my misfire was a combination of a bad Lamda #1 sensor that would not heat up and a bad cylinder #4 coil and Bad Cylinder #5 Coil. (Keep in mind I replaced all the coils and plugs Jan 2022 so go a bad batch) I did figure out how to replace coils without completely removing the radiator and only doing a partial drain. I removed the radiator hose located on the drivers left side and drained the hose into a bucket followed by removing the two clips on the top radiator support bracket. About 3 cups coolant came out. keep in mind if you have not replaced plugs or coils in 40-50,000 miles you would need to completely drain the radiator and pressure wash the dirt and rocks from the bottom fins. They get packed in the radiator fins
Testing before full assembly: I was able to run the K1600 without the radiator attached for 5-7 minutes. (Thank GS Jim for the tip) Just keep an eye on your temps! One has to put a latex glove over the hoses so the water pump will not blast coolant everywhere. So, with the radiator off, coolant hoses covered and taped up, GS911 attached I would run the bike with the coils disconnected just to verify the coil at fault. Pretty slick. Keep in mind, if one coil goes bad it can send erroneous faults to the other coils. Must throw off the timing a bit to come in as a coil.
fault. I first replaced the #5 cylinder coil and ran it and found the # 4 cylinder coil. Turned out the one I thought was bad..The # 6 cylinder was ok.
word of advice: Dont trust the GS911 read out 100% when troubleshooting coils. Run some tests. The GS911 will absolutely inform an owner there is a coil issue but you will need to do what I did and dig a bit deeper while things are torn apart. I recommend pulling the coil wire in question and run the bike. Make sure it is the coil that is bad per the GS911. Then run the bike again and check for more coil issues.

Question: Anyone ever try these Chinese BMW coils for the K1600? They say OEM BMW and are the correct part number. They also have the -04 upgrade coil but I could not find where BMW upgraded the -03 coil to -04 https://www.ebay.com/itm/165562037421?hash=item268c4434ad:g:iYIAAOSwZHRiw2Ee&amdata=enc%3AAQAHAAAAoLmJ2TyzljLO5O9f6Wv8prARoWE4Ta8tA9ylr%2BfsgfcBS49gMMKeg0RfFpYHPwx63DI9sb0hurGfC0oVS3lf%2BkgmtQuO2gabqeX3KWjOKWoWsvGwEGfvWqsWTJOkzRzR83%2B3pA2dxD5LCNLTUAAnvHkIIlWB%2BNisC6O2lhnyFyJUktny880pRea8y8ECE3B1FC8icuglieGTpRyXb1dwAq0%3D%7Ctkp%3ABk9SR4Lwo5GBYQ

Yeppers another update: If you remember I replaced all six park coils and spark plus at the beginning of 2022. Had two coils fail almost immediately. Not a complete failure but would begin missing sparks randomly. I since replaced the coils. last week Coil #3 Cylinder #3 began to fail. I replaced the coil last night and when i tested it the gs911 showed it was still generating a fault. So long story short: I seriously doubted that I could have another bad coil so determined it must be a bad spark plug. I swapped sparkplug #3 with spark plug #1. The fault moved to cylinder #1. Walaa! Found a bad spark plug. his plug only failed after it heated up to operating temps. I have a new plug on order and should arrive today. The GS911 ha way more paid for itself many times over. Thank you hexcode. I ironed out replacing coils and plugs without draining down the radiator. For the #3 cylinder I had to drain just the driver left side upper hose. After removing the tupperware, Remove the two retainer clips that hold the top of the radiator support brackets. Pull the radiator towards the front wheel and put in a block of wood. That gave me room to pull the #3 and #1 coil and plugs. I did not even need to remove front wheel.
-
Just curious, what brand/number were the plugs?
-
NGK Spark Plug LMAR8AI-8 set to .032 gap, Just had one plug over a decade that was bad. It only misfired when it was a engine temps
-
Yea bad luck, out of the litteraly hundreds of ngk plugs I've bought over the decades I have never had a failure.
-
Me2. This was the first bad plug ever 4me. It only became intermittently bad after running engine temp was reached. I first swapped out the coil and the fault was still there so then I ordered in a new plug and walla..runs like BMW is supposed too. So far no engine light and fuel economy is back to 43/44mpg

this is not correct
Cylinder #1 coil fires 1
Cylinder #2 coil fires 5
Cylinder #3 coil fires 3
Cylinder #4 coil fires 6 GS911 reads "coil #4 is the 6th in firing order"
Cylinder #5 coil fires 2
Cylinder #6 coil fires 4
GS Jim has it right in his post
Don't know if this helps but the BMW RSD says to check valve clearance by setting TDC in order of 1,5,3,6,2,4 and numbers the cylinders 1-6 L-R facing forward.
going down the list below is the engines firing order
Cyl #1 with coil 1 goes pop (thus if the bike happens under cranking to get compression on cyl 1 would be the first to go pop)
Cyl #5 with coil 5 goes pop next
Cyl #3 with coil 3 goes pop next
Cyl #6 with coil 6 goes pop next
Cyl #2 with coil 2 goes pop next
Cyl #4 with coil 4 goes pop next AKA - "coil #4 is the 6th in firing order"

Thanks Botus. I maybe made an error. I am pretty sure mine is correct but after multiple times of taking the radiator out, I was frustrated. I will keep you corrections in mind if I have to do it again. I did actually start the engine with the #4 coil out and the GS911 did send a code and the code was clearly "coil #4 is the 6th in firing order". Ultimately we need confirmation. After all my efforts I did figure out a way to remove plugs and coils without removing the front wheel and without draining the entire radiator. It requires some long socket extensions. I did have to drain the top drivers left side upper radiator hose and it drains about 3 cups. Make sure you pinch off the radiator overflow reservoir or it will drain out when you drain down the upper hose. I used a small c-clamp and some thin wood so the hose would not get a hole. Once the upper hose is drained down I removed both upper radiator retainer clips and move the radiator forward as far as it would go with a wood block. That gave me room to pull the coils and plugs. Cylinders 1-3 are simple to access. Cylinder 4-6 you have to access from the drivers right side and are more challenging.
