    testing shock absorbers

    Depends if you are planning on keeping it. It won’t be particularly cheap to change them. You can look for misting. If you’re replacing, then definitely renew the bump stops too. Up front the ARB links will usually be worn too. With the front dismantled, pay particular attention to top mount...

    Rex is toast... Any way to stop maintenance cycle?

    I agree with what others have said, avoid the main dealer. Their technicians, no disrespect, simply don’t have the technical knowledge to fix. They communicate with BMW via a portal and they don’t tend to deviate from the repair plan. You will literally spend thousands on new parts on the...

    Rex Works, tested several times by BMW (maintenance mode and driving), but...

    This isn’t like VCDS for VW or Audi. That’s supported software from RossTech. Basically buy it from EBay, search for seller with good feedback. You are looking for BMW ISTA Dealer Level Access Diagnostic Programming Coding, ENET & K+DCan Leads. Ideally run this on an old laptop that can...

    BMW Dealership is saying my 2015 REx has metal shavings in the engine and it needs to be rebuilt

    First off, don’t authorise anything. Speak to your warranty company to determine if they will cover it. There are reports of bearing collapse on i3 REx, but if it is, and bear in mind these are quite simple engines, then it’s pointless stripping down just to conclude that’s the cause. Better to...

    Grinding sound during regenerative breaking

    I swapped out front wheel bearings on my wife’s car at 70k miles. If you’re going down a bearing route only fit FAG given labour involved. Again difficult to diagnose with wheels on. I used air hammer as there will be corrosion holding bearing carrier to hub.

    what to look for i3 Rex

    Assuming this is a 94Ah car, then unless you’re spanner handy do not buy privately. I’d only buy from a garage with BMW 1 year warranty. Most independents don’t understand the nuances of these cars. You can get a health report on the HV battery using the hidden button on the screen. No real...

    Grinding sound during regenerative breaking

    It’s not good enough that your dealer doesn’t know what’s causing the noise. How have you left things with them? My understanding is that regenerative braking doesn't engage friction braking at all, so you can rule the brakes out altogether, although a cursory check would be worthwhile as the...

    That’s a hard read, and expensive too. I have had a similar situation a few years ago. Wife’s 2015 REx, just out of 3 year manufacturer’s warranty and the REx engine failed to start. Mileage would have been around 35k miles from memory, engine management light illuminated. Local independent...

    i3 rex runs for 10-15 mins then shuts down

    If REx not engaging I would renew spark plugs and fuel pump relay as a matter of course.

    Drivetrain Error Message

    That fault will be logged, the dealer is telling porky pies. I have ISTA software so on BMW fault tree it will usually be linked to EME. You can clear DTCs with ISTA, but if sensor still detects fault it will remain., Could be anything, but usually it’s a sensor regards HV insulation value not...

    Torn dust cover - shock absorber

    Watch the coil spring. Looks like nick out of the top of it, around 2 inches from the end cap. Add in road salt and freezing temperatures given it’s winter.

    Rex is toast... Any way to stop maintenance cycle?

    Don’t like the idea of not being able to fix the engine. Back to your predicament, the fuel tank is under the frunk box. Might be easier than trying to drain it with a syphon from the filler cap. This is the video for accessing fuel pressure sensor. https://www.youtube.com/watch?v=NA6Pu9Y3w2I&t=323s

    Drivetrain Malfunction error 2014 REX

    If car is on original 12v battery, then yes go ahead and replace. It’s low cost in the scheme of things. You do need to code on installation, but garage with ISTA software can do it, or you can do yourself with right kit.

    Front wheel bearing replacement

    I’m a fool! Did the bearings today. For some unbeknown reason I thought this would have a hub bolt. Wrong! These are basically bolt on bearings. 80Nm + 90 degrees. A breaker bar is essential to do the final torque. No real issues. All the bolts are accessible without moving the suspension...

    Front wheel bearing replacement

    Away to do this job at the weekend. Axle driveshaft bolt uses 17mm Allen key socket. I have 1/2” breaker bar and 1 metre extension. From what I can research it uses once only bolts, part number 33406858534. I’ll be tightening the bolt with the car raised and brakes applied, then lowering the...
