Fix - BMW 1 Series sometimes cuts out shortly after starting

[@Mark-mk1yh]

Great video which has saved me a huge load of trouble with a 2013 116i which I bought two weeks ago and had exactly the same problem. The car dealer refused to listen about the relay as being the problem so I bought and changed it myself and no more engine problems. thanks for posting this issue and the fix

Did it fix I’m having the same problem I waste money buying a new battery

Hi Mark, do you have a link to the website you ordered the relay from please? I have the same car and having the same issue. Thank you

@@MostOfficial12 I got mine from the local BMW Dealer. Do you have one locally?

[@Luanlopesdrm]

I was having the same symptoms none of my local service garage could find the problem, after googling i found your video and decided to give it a chance and ordered the part from BMW, its been now almost two weeks and the car is perfect again. Thanks so much for taking the time and making the video it helped a lot 🙏🤘

[@awesomecreator6033]

Glad it fixed it! My local garage couldn't find the problem either.

[@Dave-ci1eo]

Just had the problem on my 116i, it has happened intermittently for a couple of years. Thank you so much for posting the video and explanation. Have now ordered the relay and will replace. No codes were stored so tricky to diagnose. Always got me leaving Tesco with the shopping. Thanks Again

Got my wife leaving Tesco’s too!😢

Thank you very much. You are really great person. I have 120i 2016 , i got the error P0087 ,11A002. I change the high pressure fuel pump and tank pump. and no benefit. Some mikakni told me to change O2 sensor or fuel pressur sensor and the coil. And only one told me to change the control unit. But my car no have normall control unit. Only the small blue thing. And I go buy a scrap for 3$ but i try 3 pcs untill one of them work fine. and I ask a dealer to get one new price about 18$ for me as it is need to order no one have it ready. ❤❤❤❤ Thank you again.

[@awesomecreator6033]

Glad you got it fixed. Sorry you had to change so much unnecessarily.

[@Dan-lt1ko]

New relay solved the problem that couldn't be repaired. Thank You so much

[@awesomecreator6033]

You're welcome!

[@janoszky]

Having the same symptoms and reaction from garages…already changed the fuel pumps and sensors😭 Trying this next week…if it solves it you are my legend 👍

[@awesomecreator6033]

How did it go? Did it fix it?

[@janoszky]

@@awesomecreator6033 Believe it or not. It did!!! *bow Thanks a million. I am in a dispute now with the garage wanting me to charge a fortune (2000) for new timing and charging me loads for a wrong diagnostic as well. It was a £16 fix. I did suspect the fuel system but you helped pointing me in the right direction. Thank you so much for this vid.

[@Mrjoboo1]

⁠@@janoszkyoh my goodness same here the exact same thing has happened to me tried charging me £2k!!

[@janoszky]

@@Mrjoboo1 I hope they haven’t charged you 500 for the “diagnostics” then ghosting you when you ask for your money back.. Like they did to me…

You are a life saver ! God bless you !

Exactly what got my daughter’s running again.

[@WeThePeopleProful]

Actually have the same symptoms as you described with my BMW 116i 2015. I can drive around without any problems or fault codes yet starting is the problem and these drivetrain messages pops up with rough starting/dying after a few seconds. Tomorrow I’m going to a BMW dealer near my holliday city and hope they have this relay in stock so I can see if your tip is the golden one.

[@awesomecreator6033]

How did you get on? Did it fix it for you?

[@WeThePeopleProful]

It fixed by replacing the relay! After a few attempts starting the car it would eventually run, but very rich on fuel I found out later when I replaced the relay. Thank you for your information to the solution. Now I could drive home safely from Italy to the Netherlands.

[@hylle8697]

Thank you so much! Solved my problem as well!😊😊😊👍🏼

[@umarvega]

Thanks buddy useful information

[@tomreid6673]

So glad I came across this video I hope you could shed some light on my problem so my car starts then cuts out not whilst driving but mainly on start up it came up with the same code high pressure fuel pump intermittent had that replaced but still the same problem also it’s very sluggish at the moment could this be a relay problem in your opinion as the garage doesn’t seem to know what’s going on as there is no fault codes thanks in advance

[@awesomecreator6033]

Garages being clueless with this seems to be a common problem here! I find this really surprising because I wouldn’t really describe myself as a car mechanic but didn’t find the solution too difficult to fathom. Maybe it’s because I’m a Christian and God helps me with my problems great and small! Regarding your car, I recommend you change the relay anyway. It's cheap and easy to do yourself as you can see from this video - I’m very confident it will solve your start up problem. It might fix your rough running issue too but I’m less confident that it will as this didn't happen with mine. This is more likely to be an ignition problem with a degrading coil pack. They are about £60 each so it would be good to get a diagnostics check on them at your garage/RAC/AA as this will confirm it and even tell which one is failing. If it does show up faulty they are easy to change. I changed all 4 of mine with just a screw driver (see link below): kzbin.info/www/bejne/oZqkZmyodsqhg5Y Hope that helps!

[@wezzla]

Relay switched. Keep my fingers crossed.

How did it go? Did it fix it?

[@emmanuelmartinez6956]

I got the same sintoms with my 2012 528i do you think it may be the same problem and if it is where will be the relay on my car..?

[@awesomecreator6033]

It is likely to be the same problem but I can't be certain. The relay is cheap so it's worth a try. I'm not familiar with the 528 but a quick look on the internet suggests it may be alongside the fusebox behind the glove box. Also, there may be 2 fuel pumps as explained in the video. It was the relay for the primer pump in the tank that was causing my problem. Best to visit a BMW dealership and ask at the services counter where it can be found when you go to buy one. Good luck!

[@ahall3823]

Nice. I’m pretty sure I have exactly the same problem.

[@rudd4z14]

Heya mate great video, mines starting up and cutting out or running rough and then saying loads of codes … was yours doing the same before the relay fix ?

[@awesomecreator6033]

To be honest mine just spluttered briefly and then always cut out. The previous year we did have a different problem with it running rough but not cutting out completely - I changed all 4 coil packs and that was solved. I suppose it is possible that as your relay is beginning to fail it could be clicking in and out and so not providing sufficient fuel flow for smooth running? Or you may have both problems (which seem to occur about the same time!).

[@LEGACYPRODUCTIONChannel]

I’ve got same provlem on f30 n13 engine. Does it would be the same ?

[@awesomecreator6033]

It could be. Impossible to say for sure without trying it.

[@LEGACYPRODUCTIONChannel]

@@awesomecreator6033well i not yet trry.. but changed my pressure fuel sensor, its work for 2days. Then became back like that.. and i just bought new fuel pump 😂 If i change the fuel pump, if its remain same, will try change the relay

[@LEGACYPRODUCTIONChannel]

@@awesomecreator6033but, you told me, it’s cant start right? Did you try start & press the gear pedal fully ? Mine will start if i done that.

[@Itstheoaks]

I had a car crash into the back ofe the other day with some force...it initially looked like it was just the rear bumper that was damaged but now my car has this fault ..could it have damaged the low pressure pump in the fuel tank possiblly?

[@awesomecreator6033]

My best guess is that the timing of this fault starting after your bash is just a coincidence. It's very unusual for fuel pumps to repair themselves so it would just stop altogether if it were damaged. Secondly the low pressure pump sits inside the tank so if it received a significant impact your tank would probably be spilling fuel and you'd soon know about it. It is possible that there's been some twisting in your rear offside wheel arch and that has damaged the relay which sits there as shown on the video. I still think it more likely that the relay has the same intermittent fault that mine had and it would have failed even without your crash!

[@Itstheoaks]

@@awesomecreator6033 it was the turbo pump filtered pipe had snapped

[@FawadKhan-u4y]

What is the name of this tool or how can I find one

[@awesomecreator6033]

You don't need any special tools. It's the relay for the fuel tank primer pump that I changed to fix this. You can buy one from a BMW dealership.

[@maz872]

Do I need to disconnect the battery before replacing

[@awesomecreator6033]

I didn't disconnect the battery when I changed mine and it was fine.

[@KamilaDrage]

What its this connected name? Where is it on bmw 1 series 2007 diesel

[@awesomecreator6033]

Mine was the MK2 model from 2011 onwards (also know as the F20) and was petrol. Diesel engines require much higher injection pressure and so the system will be different. It may still have a relay fault, though I'm not familiar with the diesel version - sorry.

Which relay do i need to order
