REBUILDING A CHEAP BMW M5 COMPETITION | PT 6

I cannot wait to finally drive my BMW M5 Competition. But I've just made one small and potentially expensive mistake which is about to set me back even further. The mechanic I bought this M5 off decided it wasn't worth fixing because of the structural damage only trained technicians can repair. If this don't work, we have a problem. But despite that, I took a risk and decided to repair it myself. And despite all odds, I managed to do it. And the car was starting to look like a bargain. But the more I'd repair, the more I'd have to spend. But little did I know, I was about to run into more expense. So before we deal with this situation, we've got some unfinished jobs to do in the interior. And quite clearly, well, we're not finished. Just like the GT3, every airbag has deployed in the M5. And what's in this box here are some new curtain airbags. In the last video, we tackled the biggest part of the airbag system. The passenger side airbag which required me to change the full dashboard. But we've still got a lot left. And one of them is the curtain airbags. They are held in with these non-reusable clips which are a nightmare to get out. And then a few T30 bolts which hold it to the frame of the car. Remember, these curtain airbags have to be really well secured. Because when the canister ignites the airbag, you don't want the airbag flying across the car. And now we have the old one off. Here is the new one with all new clips and a brand new airbag canister. I tried to find these second hand on eBay but I had no luck. So I ended up buying them direct from BMW. But the pricing wasn't too bad. But we'll get to the pricing later on in the video. But now the curtain airbag is installed, I can start putting back all the trim pieces. And start making the M5 interior look like an interior again. And of course, I've got to do the same on the driver's side. Job done. Curtain airbags in. There is one more airbag to go. And that is, of course, the steering wheel airbag. This one was broken. But before we go on to the steering wheel airbag. I need to remove this steering wheel. Because we've got some goodies for it. This is the old paddle shifter. Imran from Evolve has got us some new uprated paddle shifters. To disconnect the electrics from the old paddle shifters. There's just a slide pin that we need to push out. And then the electrics literally just pull off the old paddle shifters. Then all I've got to do is get the electrics and the spring. And connect it onto the new paddle shifters. And slide in that pin back again. Once I've done that. I'll push the paddle shifters onto the back of the steering wheel. There's one electrical connector. And one torx bolt to hold it in. I'll just do the other one. Then we'll put it in the car. It's the little upgrades like this that really make the difference. When making a car your own. But let's not get distracted. We've still got to fix this thing. So here is the new steering wheel airbag. But we then need to move on to another part of the restraint system. And that would be the seatbelts. You guys should all know by now from watching my videos. When the airbags deploy in a car. It usually locks the seatbelts out. So it pulls the passenger or driver back into the seat. So the airbag deploys not right in your face. Now luckily in this case I didn't have to buy four new seatbelts. I sent the seatbelts to the airbag team. Where they put on new tensioners. You can see the canisters here on every single seatbelt. Which still isn't the most cheapest of things. It's £399 for all four. But to buy new seatbelts with tensioners from BMW. You're looking at around £300 per seatbelt. So it's not a bad saving. Fitting the seatbelts isn't too difficult. But if you don't make sure the seatbelt is in the right location when fitting it. It's likely that it would just stay locked out. So you have to be careful to an extent. Once I put the driver's side seatbelt in. I can put the trims back in. To make it look nice and neat again. And then I've got the rear seatbelts to put in. And they locate just underneath the parcel shelf. The M5 is really putting me to work today. But it's a good thing because I need to burn the calories off. Whilst I was over in Florida. I realised the portion sizes of food were huge compared to the UK. Which made me miss my YFood meal replacement drink even more. So much in fact YFood. I've actually made or thinking or close to making. A special edition MA Matt Armstrong bottle. This is absolutely crazy. When YFood mentioned that this possibly could happen. I was smiling ear to ear. I just need all of your guys support to get it through the final steps. Now if you don't know what YFood is. And this is your first time hearing about it. It is a meal replacement drink. It's not a diet drink. It's not a protein shake. It simply replaces one meal throughout the day. Inside one of these bottles is 26 vitamins and minerals. High in fibre. It's high in protein. It's lactose free. It's gluten free. And there's no added sugar. So if you're like me and constantly on the go. But also want to stay on the healthy side of things. It sounds like YFood is for you. And there's loads of different flavours to choose from. All of these bottles are 100% recyclable. Nice. So what we need to do to make this bottle an actual reality. I need you guys to click the link in the description box below. Go get a taster pack with the discount code below as well. Tell me your favourite flavour. And with that favourite flavour. We'll make that the MA special YFood drink. Thanks so much to YFood for sponsoring this video. Let's crack on with the M5. The interior is back in and looking fresh. The best it's ever looked since I've had the car. It's looking super clean in here. But one thing that we don't know yet. Since replacing the dashboard. We haven't checked to make sure everything works. There was so many electrical connectors. Bolts and all sorts of stuff behind this dashboard. And we want to see whether it works. We're on. Well I've not started it. But the dashboard is all on. We've got so many warning lights. Oh wow. Oh no. No, no, no, no, no, no. Okay. Okay that's not working. Oh. Oh it did work. Oh it does work. Sometimes it works. One thing that we do have on. Is still a restraint system warning light. And that's because we're still not finished with the restraint system. The next part of the restraint system. Is actually to do with the bonnet hinges. And you can see them just here. And they're on both hinges each side. I managed to get a new set of these hinge thingies from eBay. For £115. Which is still quite expensive for these little small things. But from BMW it's a lot more expensive. These things are actually called pedestrian protectors I believe. And they're designed to protect a pedestrian if you hit them. You can see the bonnet rises here when the pedestrian is hit. To act as a sort of cushion for the poor guy when he whacks into the bonnet. Now as mine have been detonated. They're not going to detonate again. And that's why I need to replace them. And due to how bad the bonnet was all twisted up and bent. I'm also going to be replacing the bonnet hinges as well. In my experience I've found that this is a pretty good idea. As when you buy a brand new bonnet and you're trying to line it up. It sometimes can be really difficult. If there's a slight bend in the bonnet hinge. And it's really difficult to tell. So sometimes it's a lot better just to get new hinges. But we're not in the all clear just yet. In order for the protectors to detonate. We need sensors on the front of the car. What's in this is. I'm still not too sure how these work. There is a sensor at each end of the car. With a sort of vacuum line. And when this gets pinched. It sets something off in the sensor. Which pushes those pedestrian protectors upwards. And this well I'll show you where it goes. This line and the sensors slot into this foam piece. Which sit on the crash bar. And I assume if that airline gets a pinch. Or registers an impact. Then it will send a signal to the pedestrian protectors. To pop the bonnet hinges upwards. And with those fitted. I can now slide it onto the front crash bar. And then it's on with the new wiring loom. Which I had to buy from BMW. Again more expense. Each one of these plugs is going to plug into something. I know is going to be expensive. Because it's electrical. But the good news. The restraint system is almost there. One final thing. The channels all time favourite. The pyro fuse. This thing breaks when the airbags deploy. Stopping you from starting the car. Because what it does. This pyro fuse goes on this side here. All this fuse does is isolate the power. Going directly to the starter motor. So you can no longer start the car. Now to get a pyro fuse from BMW. You have to buy this full section. Like most cars. Which is over £550. But just google the part number of the pyro fuse. £21.99 off Ebay. And they're used on in fact most cars. Even Rolls Royce used this. Let's get it in. If you've missed a few episodes. Then we've been able to start the car. By bypassing the pyro fuse. And if you ever buy a crash damaged car. Which won't start. This is the best place to start. We can bypass it from moving the cable. Which sits on the pyro fuse. Over to the main body electrics. Again it's super sketchy. But it seems to work. For short term use anyway. But now that I've got all the airbags. And restraint system in. I feel comfortable enough. To refit the pyro fuse. And luckily on the BMW. It's not in a too difficult position. Moving on to my headlight situation. I bought two second hand headlights. And even though they're the right part number. Only one seems to be working. These were £800 each. And I hope it's money not wasted. So the left headlight. For no reason at all. Doesn't work. But the right one. Works completely fine. So apparently. I've been speaking to Defined Coding. On Instagram. And he says. Now a lot of the electrical parts. And the modules on BMWs. And a lot of new cars. Are locked to the VIN of that car. Especially if you're putting on a second hand part. He's trying to stop people from stealing parts. And then putting them on other cars. We could potentially have a stolen headlight. Or. We could. All we need to do. Is code it. To the car. Which is more than likely. I don't think it would be stolen. But we're about to find out. I had to plug this cable. Into an OBD port. Which then goes to an Ethernet cable. On the laptop. Then Defined Coding. Was able to remotely. Code the car. It's one. Okay. One just came on already. That was like two seconds. Come on. Defined Coding. You absolute legend. That was like. Three seconds. Done. Legend. Here's the plan. There's an issue. Which we're going to get to. But of course. We're missing body panels. And this has got to go to the body shop. At some point in it's life. This is the old wing. Or fender. If you're American. Thought it was saveable. Doesn't look that bad. But this has been dented. That maybe could have been pulled out. In fact. Oh no. It's all been creased up. That's why. Yeah. The whole thing's creased. So. I looked on eBay. Couldn't find any. But. From BMW. About a couple of hundred pound. For a brand new wing. From BMW. So at least guaranteed fitment. I just want to bolt it in. With a few bolts. Because. Of course. The body shop's got to take it back out. And they're going to go mad at me. If I pull it in properly. It's looking better already. We've got a plastic silver steel to take out that. That's one wing on. Next step. Bonnet. Here we go. A brand new BMW bonnet as well. Which the price in there. Was. Cheap. We'll get to all the prices at the end. This is a lot cheaper than buying. A brand new second hand one off eBay. In fact. It's around the same sort of price. But. The convenience of. There we go. Finally. The M5 is starting to come together. If it wasn't for that one mistake. In the last video. I vacuum filled the coolant. And actually got it running. Until. Well. This happened. Coolant started to fly out of somewhere. And it was being thrown onto the auxiliary belt. Which made it so difficult. To find out where it was coming from. So there's actually two mistakes I've made here. And. One. I think the coolant line. Is this bottom one here. And turns out. I think it's rubbing on the belt. And it's rubbed through. So my mistake completely. I think I've routed a coolant hose. In the completely wrong direction. Which lead it to be resting on the auxiliary belt. And that's what's caused this hole. Here. And. 77 pounds later. A new hose has arrived. This time I've got to make sure it routes the right way. And once I've got that installed. I've then got to vacuum fill the coolant again. Which means putting the vacuum filler. Onto the expansion tank. Blowing air across it. To suck a vacuum. And make sure it holds it. Before putting in some more coolant. Well it's holding vacuum. So there must be no leaks. In the engine cooling system. Which brings me on to mistake number two. And actually I've got an excuse for this one. It's not actually my fault. I used the wrong coolant. BMW's take green coolant. Thanks to all you guys who commented and said. I should use green coolant not red coolant. I asked the parts place I got the coolant from. For coolant for the BMW. And they sent me red. So I just trusted them. And. Well I was wrong. Turns out it was green. Let's suck it all in. And then we can just about. Get the bumper on. And get it out on the road. Now I'm really getting excited. To drive an M5. For the first time ever. And with the cooling system vacuum filled. I've now got to fill up the charge cooling side. Which has a separate expansion tank. But here's mistake number three. You can see on the gauge. That the vacuum was dropping. Before I even added any coolant to it. But I completely ignored it. And still added coolant. And I soon found out. Why I shouldn't do that. Just when you think. You've done it. And bled the system. There's more. There's too many cooling systems. On this car. Like this. Radiator here. This is like the only. Last few hoses I've not replaced. And. You can just see up there. That hose must have the tiniest of pin holes in. And there's. That one's going. Is this one here? Top of the radiator. Can you replace this radiator? Yeah. Okay. Yeah replace that radiator. So it's top one. And that is leaking out. Of the hose. You can just see it up there. Oh my god. That side is the charge cooling side. The engine side seems good. Charge cooler side. No good. Here it is. The hopefully the final culprit. The tiniest of pin holes. Is holding. This whole car back. But that shouldn't stop me from getting this car. On a trailer. Where I can get the bonnet. The wing. And the second hand bumper. That I managed to pick up. Painted at the body shop. But I'm beginning to think. Some of you guys were right. These are all receipts for parts. I'm not going to write each individual part. But. The remaining parts. That I've bought. Has cost me another. £2,700. Which now brings the total build cost. Including the car. To £39,569. And the cheapest one. On autotrader right now. Which is a similar year. And spec. Is £51,190. But. That one isn't crash damaged. So we're really cutting it close. But I think we're going to have an amazing M5 after this. Thanks so much for watching this video.
