Cold Start Problem!

Hi, I'm new to this site so an introduction needed! My names Alan and I own a 3 series E46 2.5i saloon 2001, I live in the Kingston/Tolworht area.

I have in the past had some of the usual problems, like the inlet rubber pipes being perished, which I replaced! and in the main she drives really well.

But I do have one problem that is really annoying when it happens.

If I haven't used the car for 3 or 4 days and it's a very cold morning when I do try to start her, she fires up but wont start it's really lumpy and just doesn't want to run! If I then leave her until it's not so cold she runs as normal. If I have been using her daily and it's very cold she'll start no problem!! Very strange!

I am at the moment getting a bit of a funny whistle when I start her from cold, but within 5 mins it's gone.

Anyone have any ideas please?

Thanks

Alan

Welcome to the club Alan.

There could be a number of factors involved. When was the last time the car had a full service done on it?

The whisteling could just be the alternator having to work hard initially because your battery is starting to struggle in the cold weather.

      Folding mirrors

      Morning Damion I would say yes to the software update (but a Dealer will charge £££) this should be in iDrive try My Vehicle, Vehicle Settings, Doors/Key, then scroll down to mirrors and check Fold Mirrors when Locked If that doesn't work you need help from someone with a BMW capable diagnostic package (ISTA/INPA) to check if it is in a hidden menu. Be aware BMW are making it harder and harder to tinker with the cars mainly after 2019 year so you should be OK Dave

      Centre console iPhone charger

      Morning Rob His was in the car when he brought it and is OEM (car is BMW 330e 2019) apparently works well with his iPhone but not with our daughters Android phone. You could talk to your Dealer but make sure your wallet is in a protected spot 😁 as I have know idea of cost ££££. If BMW are fitting them then there will be Retro fit kits out there from the Far east so worth looking at the Auction sites but I have no knowledge of quality other than the screen in the X5 failed and I replaced it with a complete Android unit from Ebay at less than a 1/3rd of the BMW quote. Truly plug and play allows switching between the OEM CiC and Android gives better GPS and many other programs and has been totally reliable for the last 3 years (that's killed it ) Me I don't spend long enough in the car for my phone to need charging these days 😅 While the X5 has Android Auto and Carplay I have to say like a lot of gadgets they are rarely used. Bluetooth is the only thing I see as an essential Good Luck with the search for a solution Dave

      Folding mirrors

      My X6M has folding mirrors, operated from the normal button, situated on the drivers door arm rest. They don’t fold in when I set the alarm, having read the manual, there’s a setting in the idrive to activate this function but when I scroll down the menu, this option isn’t there. Can the software be updated to add this feature, surely if the button is there and the mirrors are folding ones there must be a solution, or am I missing something completely Thanks in advance
