Fix - BMW 1 Series sometimes cuts out shortly after starting 

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?

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

Got my wife leaving Tesco’s too!😢

How did it go? Did it fix it?

@@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.

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): ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kiA59rAenM4.html Hope that helps!

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

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.

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!).

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!

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

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.

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!

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

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.
