Are the sensors showing up as fault codes or are they not reading up correctly on live data? It's not uncommon for the modules and wiring to get damp/water damage on these.

How cheap is the kit? As normally it's very expensive, and the price to buy the kit just to fix your own car wouldn't be worth the money. Those kits are normally in the thousands range.

Normally it's because the O ring style gasket flattens out. You can get a new gasket for them fortunately. You'll need to remove the pump and take the top off to replace it, while you're there you should replace the O ring between the pump and cylinder head.

You should yes Gazza, as the new discs probably won't fit over the shoes, also if someone has previously not set up the handbrake correctly, you may end up with a poor handbrake.

What size tyres do you have at present and what size are you going to be running?

Are you able to monitor the fuel pressure live readings? Also the boost pressure reading? When the faults are cleared, is there a certain rev range that the fault code comes in at? Does it list it in the fault code data?

No, you can specify that the badges are removed from new by the dealer. Many people do it to try and make people think they have a better model than they really do.

First port of call should be to get the fault codes read using specific BMW diagnostic equipment, you will be able to get much deeper into the issue. I'm guessing you had the fault codes read with a generic EOBD code reader?

BMW X3, X5 CV boot, CV joint replacement guide. Jack up the car and place an axle stand under the vehicle. Remove the wheel and loosen and remove the driveshaft nut. Using a drift/punch, tap the driveshaft through the hub, you won't be able to get it fully out yet though. Undo both of the lower suspension arms, inner bolts. Pull the hub away from the driveshaft, you may have to use a punch/drift still to get the driveshaft out of the hub. Pull and twist the hub out of the way so you can get easy access to the CV joint. Cut the old CV boot clips off and cut the old CV boot off. I clamp the driveshaft with some vice grips/molegrips, to stop the driveshaft moving outwards, then hit the old CV joint off from the end of the shaft. Clean the old CV grease from the shaft, then slide your new CV boot onto the shaft. If fitting a new CV joint, fill the inside of the joint with fresh grease. Tap the CV joint back onto the shaft, then resecure the CV boot to the joint and shaft. You can now fit the parts in reverse order from when you took them apart. You should grease the splines on the end of the CV joint to stop it rusting inside the hub. Remember to torque your suspension arm bolts, driveshaft nut and wheel bolts to their required torques.

BMW Z4 rear spring replacement DIY guide. As you can see this spring has seen better days, the bottom piece has broken completely off. Remove the rear wheel. See here the bottom of the spring is missing. Use a jack or similar and support under the rear hub, this will stop the hub from firing down when you remove the lower shock absorber bolt. Undo the lower shock absorber bolt. Lower the jack from under the rear hub and pull/lever down on the rear hub and pull out the broken rear spring. Here you can see the difference between old and new. Pull down/lever down the rear hub and fit the new spring. Jack up the rear hub and fit and tighten the rear shock absorber bolt. Refit your wheel and torque up the wheel bolts. Job done.

BMW 5 series E39 rear pads, discs and handbrake shoe replacement. Loosen rear wheel bolts, jack the rear of your car up, place axle stands underneath and then remove your wheels. Pull the handbrake gaiter out and using a suitable socket, slacken off the handbrake cables. Rotate the disc until you can see the brake shoe adjusting wheel. De-adjust the shoe adjuster using a screwdriver. Remove the caliper securing spring. Remove the brake pad sensor. Remove the 2 plastic caps then using a 7mm Allen key, remove the Allen key bolts. Remove the brake pads then undo and remove the caliper frame securing bolts.(16mm) Remove the disc retaining Allen key bolt(6mm) Using a hammer, give the disc a sharp hard hit to slacken the disc from the hub, then pull the disc off from the hub. You can see here the inner handbrake surface is pretty rusty, compromising the shoes gripping the disc. Using a 5mm Allen key, remove the shoe retaining pins. To remove the shoes, I use a long screwdriver on the top spring and lever against the hub to remove the spring, then pull the complete shoe set down with the bottom spring and adjuster still attached to the shoes.(New shoes in pics as I was in a rush) Clean up the brake back plate with a wire brush, clean up the adjuster and handbrake fulcrum/lock, then lightly grease up the contact points,(be careful not to get carried away as any grease over the shoes will negatively impact performance), grease up your adjuster threads and your handbrake fulcrum/lock, then refit your handbrake lock to the cable. With your new shoes off from the car, fit the lower spring on the shoes, slide in the adjuster, then open up the shoes at the top and then slide them over the hub and into position, then secure them with the retaining pins. Now fit your top spring, same principle as when you removed the spring earlier, use a long screwdriver and lever against the hub, double check the shoes are all located correctly on the adjuster and handbrake lock and all springs are fitted correctly You're now ready to fit your disc, make sure the adjuster is fully wound back in as shown below before attempting to fit the new disc. (Ignore the lack of lower spring, photos were taken at different times during work) Fit your new disc minus the Allen key securing bolt, rotate the adjuster until you can no longer rotate the brake disc on the hub, then back off the adjuster 5 clicks, make sure the disc spins easily enough backwards and forwards, you can now fit the disc securing bolt. Clean up your caliper frames, mainly where the brake pads come into contact with the frame, the pads should be able to slide easily in the frames with no great resistance. A wire brush, sandpaper and/or a file can be used. Then copper slip the points where the pads make contact with the frame, make sure you don't spill to much on the inside of the frame, else it will go over the disc when fitting the frame. Bolt up the caliper frame and torque the bolts up to the required setting. You're now ready to push the caliper pistons back, remove the reservoir top and check you have sufficient space for the excess fluid in the reservoir when the pistons are pushed back, else it will overflow out. You can use a syringe or lots of tissue paper to soak up any excess fluid. Apply some brake pad anti squeal to the rear surface of your pads before fitting them, then bolt up your rear caliper, torque it up, fit your anti rattle spring and your new brake pad sensor. Once you're happy everything is fitted correctly, pump the brake pedal to allow the pads to come into contact with the discs, then check your brake fluid level. Fit your wheels and torque them up to the required setting. To extinguish the brake pad warning light, leave the ignition on for 30 seconds, it should reset itself, if it doesn't then check your sensor is connected properly, else you may have a faulty sensor. Later models with iDrive will need to be reset through the dash or with diagnostic equipment. For the first 100 odd miles you should avoid excess heavy braking, to allow the pads to bed in nicely.
