I have a 5 yr old Rex with 50,000 miles.

Maybe 10,000 or less of that has been done with the REx.

BMW now say it needs:

-new injectors
-O2 sensor
-software update.

£1,000

Injectors failing on a car, especially a BMW, with 10,000 miles?

And then, maybe masking underlying faults with the HV system as those error codes won't clear until the above is sorted out.

This is the most unreliable car, and most unhelpful car company, I have ever had the misfortune to deal with.

Anyone else had this?

Thanks.

Knowing nothing about this car, I'd be tempted to replace the O2 sensor and do the software update and see what happens.

Injectors failing at 10,000 miles on a scooter engine? I used to ride BMW bikes and that seems a bit of a stretch.

Have they told you what codes it’s throwing or have you read them?

Injectors doesn’t sound plausible to me and software update? What software update is there for the Rex, I’m not aware of anything specific on that front unless it’s the regen related one that they implemented to back off regen when the rear wheels lost traction. That’s quite an old version if it is but not specifically to fix a problem with the Rex running. Thought it was more to do with the Rex engine mount problem and since they’re not telling you there’s an engine mount problem that would seem odd.

O2 sensor problem is going to cause the car to object so I’d think about that first. No idea how easy access is to swap an O2 out on the i3 though. The process is similar to a spark plug renewal IF you can get at it :rolleyes:

Happened to mine, same diagnosis, luckily the car was still within warrantee.

Mine had 14000 on the clock, of which I'd be surprised if the ice did more than 2k

I wonder if the lack of use is causing the injectors to fail?

If it's out of warranty anyway I'd find an independent to look at replacing the sensor if your not up to trying yourself. At the end of the day an engine ought to be an engine and this is a basic one at that. Access is likely to be the biggest issue, but you gotta look to know the answer to that one.

There's a BMW independent specialist guy near me in Manchester that I'm sure has worked on an i3 before - don't suppose your near here?

My i3s is going in this afternoon as I have an amber warning light saying the Rex is inoperative... It was -5 this morning but still... its only done 4,500 miles

I might not want to give the ICE hire car back ;)

UPDATE.. my fault was a simple fuse for the Rex cooling fan... pick her back up tomorrow
