Evening All,

I got a 2017 BMW 4 series 8 months ago, got it privately and it was it tip top condition. Showroom condition, full BMW service history etc etc.

Fast forward 4 months and it starts getting random issues such as "no key in car". I took it to BMW who said no errors or warnings showing, call us back if you have any more issues...

In Feb, I got to get in the car and the dash lights up but nothing else, towed to BMW to have the car reset and it's fine. Another couple of weeks of trouble free motoring before the headlights are then trying to light up the moon, they reset until I start driving and then they automatically start facing the sky.

Then finally this week, it's gone and lost the BMW maps. No big issue but a total pain when you're out somewhere and can't get back home quite as easily.

So - what do I do with this? Really can't figure out what is causing it, or if I'm starting down the rabbit hole of trying to diagnose an electrical fault somewhere?

I’d get the battery properly checked it’s typical for BMW batteries to last about 5 years and a failing one can cause all kinds of weird faults

As a relatively cheap starter for 10, has it had a new battery at any point?

As above, possibly the battery and it'll need to be coded to the car. BMW and electrical oddities go hand in hand.

I think your post was aimed at selling the car not fixing it and also the adage that you are generally buying someone else's issues with a used car.


Only you can decide how many issues are enough before you sell. Depends on the cost of fixing them.

offloading the car via WBAC might be an option you were seeking.

Fit a new battery and get it coded, if that solves it all well and good. If you still get gremlins after that maybe consider moving it on? Dedicated auto electrician probably better than BMW 'techs'!

I don't believe it has, that'd be a good call actually. I was assured that it had been tested, but I'd suppose that's only over a 2-3 minute period

Very valid point.

I love the car, so it's by no means the default option. Just that when I'm doing 80 miles a day the last thing I want is to stuck in a car park or startling someone coming the other way

I refer you, modestly, to my thread about my E500 wagon that I still have. That really has been trying my patience, and ravaging my wallet.

BMWs are very temperamental when the batteries need changing

In fairness, most modern cars are.
I've certainly experienced gremlins with Mercedes and Lexus due to degrading batteries.

You'd think they could include some code to assess battery health and warn you to replace the battery before it gets to the stage that subsystems start acting up, especially seeing as every car smart enough to have this issue seems to have a hidden menu revealing it knows the battery voltage at all times and in all conditions.

I bought a 2008 S Class a couple of years back, still own it and went into it with a view that it will need something done. Hugely complex, fairly old and running costs of a car that was once £65k.

I did 900 miles in the first month, the same as it had done the previous twelve and I unearthed some common issues.

Wheel speed senor issue, one fails replace all four £200. EGR valve failed, £500. Leaking suspension valve £200, conductor plate in the gearbox £950. Fortunately all of that was covered by the warranty as I bought from a garage. Next MOT cost me £1,200 (inc. two tyres) as needed some bushes replaced.

Admittedly, if I'd been paying out for all of that from my own pocked I'd have been a lot less inclined but I knew the risks of buying the car and did my homework.

Since then, it's been pretty good and behaving itself. I know these cars do 2-3 times the mileage mine has and it's an awesome car so well worth it.
