Grab a YFood Taster Pack Here USE CODE MAT-YOUTUBE bit.ly I'm rebuilding the cheapest BMW M5 Competition F90 i could find on the internet. But the M5 was cheap for a reason. A previous accident left some pretty heavy structural damage and left alot of expensive parts broken. Whilst im restoring the car im also taking the opportunity to upgrade some of the older parts. But will all of this be worth it or would i have been better of buying a straight BMW M5?

Notes
This video continues the ambitious project of rebuilding the cheapest BMW M5 Competition you can find online, focusing on structural repair, restoration, and meaningful upgrades. The host explains that the car arrived with heavy structural damage around the strut towers, requiring him to remove the engine, drill out rivets, panel bond, and re-rivet a new strut tower to restore rigidity and alignment. Despite the complexity, the M5 remains a bargain at around 1,100 pounds, although the price tag climbs as additional parts arrive. The episode introduces key upgrades, including brand new windscreen, CSF charge coolers, and upgraded air intake components, highlighting the goal of improving reliability and performance while pushing the car closer to a restomod vision. The video also captures the tension of racing against time as the crew tests electronics, bleeds the cooling system according to BMW’s procedure, and plans to fuse all upgraded components with a correctly coded and installed dashboard. The creator acknowledges both the excitement of upgrades and the ongoing need to repair remaining systems, underscoring the overall challenge of turning a wrecked M5 into a reliable, fast daily performer.

Questions answered
- What caused the initial electrical and lighting issues on the BMW M5 Competition, and how are they being addressed?
- The issues are linked to headlight modules and coding requirements. The new headlights require proper pairing with the car's ECU, and some viewers note that encoding is essential for ISTA to synchronize modules and VIN data. Solutions discussed include headlight coding by experts and, in some cases, remote coding with the right hardware.
- What upgrades are being added to the engine bay and why?
- Upgrades include CSF charge coolers, a high-performance induction kit, and carbon air intake components. These parts improve cooling efficiency for the turbocharged engine, reduce intake restrictions, and enhance overall look and potential performance gains, while also addressing a more modern, restomod aesthetic.
- How is the cooling system bled and what issues can occur?
- BMW recommends a specific bleed procedure involving the heater on the hottest setting, fans at low, and engine idle with the accelerator held, to purge air from the cooling system. In the video, a leak is detected during vacuum testing, which is then fixed by replacing a damaged hose, illustrating how air pockets can impact cooling and how careful vacuum testing helps confirm a leak-free system.
