Servicing i3 REx

Tue Nov 13, 2018 3:40 pm

I know this has been covered to various degrees, but would like specific advice please.

So my wife's i3 REx (2015) is on 28k miles is due a service. The car's engine did a fair bit of work coming up the road from Blackpool to Scotland last year when it was purchased. The engine has been used intermittently but usually is electric all the way since we fitted an electric charging point to the house.

The car was given a visual health check earlier this year before the 3 year warranty expired, so they sorted torn dust sleeves on the front shock absorbers (both sides) and replaced a fuel pressure switch.

Around the same time the car was given a brake fluid change. BMW charged £100 which I thought was okay, but it's a bit of a nonsense, when you actually think the fluid costs just £10.

So anyway, from what I can determine the service gets the air pollen filter changed, oil (2.5 litres), and oil filter. They say brake fluid too, so now it's done it should be good for 2 years. I've reviewed some online videos and it looks straight forward. I've serviced my own cars for years including my brother's X5 which is an absolute brut to work on. Only car I've had to use a small step ladder to access the air filter! :lol:

Because the car is now outside warranty, will I invalidate the battery warranty? I plan to purchase the OE parts from BMW and receipt them.

Only down side I can see is getting the service reminder cancelled or reset. I have VCDS for VAG cars to reset intervals, and I assume BMW do something similar. Would BMW reset it if I could prove it was done as part of software check? Judging by my main dealer's front reception, I reckon they are going to be funny buggers.

The service items can be reset yourself with the trip meter button. With the car in accessories mode ("OFF" should be displayed on the driver display), press and hold the little button on the side of the display until a "reset possible" message pops up. Short press to cycle through resettable service items, long press to reset that item.

The W20 engine manual was helpful for me in locating the oil filter and drain plug. REX oil change isn't very hard.

Servicing the REx should have no impact on the battery warranty.

The OEM brake fluid is moderately expensive, but most of it is labor to actually flush all of the old stuff out.

THanks for that. This was done earlier this year at the main dealer for £100 ($129) which I though was okay. This type of servicing as bite-size chunks, bit like air-conditioning re-charge is the way to avoid hefty one-off service bills.

Thanks for that. My wife is oblivious to service reminders and error lights anyway! :lol:

She borrowed my daily driver (Škoda Fabia diesel) and said the oil light had come on. I knew it was unlikely to be oil pressure, so said add some oil. Turns out it was the engine management light for a goosed air temperature intake sensor. Ended up having to drain the oil, as she put the best part of a litre in!

Here is a link to the oil change section on a BMW Technical Information System website.

So picked up pollen filter, oil filter and sump plug (£64) at the weekend along with new 427 wheels and Bridgestone Blizzak winter tyres. I'll change the 428 Turbines next weekend when I service the car. I asked about oil (£22 a litre at BMW stealer), sorry but given I'd paid a fortune on wheels, i can pick up Castro Edge from Costco.

So parts representative (he looked like the elderly gentleman from Up) said it was 5w30, but when I checked Castrol's site using their registration finder, they say 0w-30. Any preference, and am I correct with 2.5 litre capacity. :?:

2.6 liters according to the BMW guide.
5w unless temp. frequently drops below -20 °C, then recommend the use of 0w instead of 5w products (service manual)
