Mini fuel pump relay replacement part 4

Fuel pump relay is complete. Installed back in car and everything works perfectly.
If I did it again I would consider heating (with soldering iron) and removing all pins joining the 2 boards, rather than cutting them. They could then be used to reassemble the board at the end.

I can’t thank you enough for posting this repair. I had the exact same symptoms in my mini and it was looking like thousand of dollars in mechanics fault finding. I followed your instructions and sure enough the same soldered joint had failed with the same heat discoloured circuit board under the relay. In the end a relatively easy fix. I have brought a replacement relay but didn’t require it. Car is back running with no issues…….other than the normal Mini Cooper issues. Thanks again, you saved me thousands of dollars.

Did the hard work pay off in the end? I've replaced my HPFP, LPFP & now just had my board done because my stalling issue hadnt gone away.. fingers crossed

Hello, I have changed this same box on my 2013 Mini Cooper, but the fuel gauge has been blocked. Could you help me identify the problem please. Thanks for your help!

sorry I think the fuel gauge is not necessarily related to this

hi. i have the mini r56 diesel version from 2011... The relay is the same as in your video for diesel versions?

@Realminishorts 10 ай бұрын

to be honest not sure. but diesel does have a FUEL PUMP PRESSURE REGULATOR CONTROL VALVE about £45 which might be easier to check / change first; and or a fuel rail pressure sensor about £35. Diesel does have an in-tank pump like the petrol so perhaps it has this relay too, but I haven’t read about it. Would have to take apart your JBE to find out

@@Realminishorts actually it has 2 pumps. 1 is in the tank (the low pressure pump) and another one on the engine ( the hig pressure pump) the problem of my low pressure pump doesn't recive electric power to start iven when i do the bleeding procedure with ista d... some time the power is to low and the pump dosnt start.

Hi! Today i checked the fuse panel and the relay is in the same place with the same problem is you had... the soldering is cracked and the relay doesn't provide electricity to the fuel pump... now I will repair the soldering and I will try to do the bleeding procedure to se if the pump will start...

that’s great news (!) thanks for letting us know as there will be other people in the future who need to know! now we know diesel has the same issue. you are the first to find out.

Yes. It was the same problem... the engine it's a n47 bmw diesel and first everyone sees it was the hig pressure pump but to be that pump, mast make iron particles when is broken and you can find them every were , in the fuel tank or in the comon rail. Best way to ceck the hig pressure pump is to remove the sensor from the hig pressure pump and under that sensor you will find the most part of iron particles if the hig pressure pump is broken, if is clean you need to ceck tha low pressure pump, fuse or releay... have a nice day and thank you!

Had the exact same problem. Followed your steps exactly, replaced the relay. hardest part was soldering all those pins back together. My mini drives great now! However now I have a list of NEW problems, no interior lights, headlights not turning off, no indicators, no hazard lights, front windows won't go up or down. ambient lighting not working. No idea where I went wrong.

that is the FRM module, unfortunately it needs reprogramming by someone with proper software and experience. it is on the other side of the mini in similar location, but behind the panel where the bonnet release catch is. ‘Footwell Module’. It is caused by low battery voltage / disconnected battery. once it occurs nothing you can do but get it reprogrammed. Do not need to buy a new one which is what bmw will tell you. there is usually someone in most countries that can do it.
