intermittent drain on battery, replaced twice, thought it was screens but it wasn't. Alternator fine, left for 2 weeks and stated up fine, but still can flatten overnight. Jumpstart and it's o.k.. Driving me mad, can anyone out there help?

If the battery is perfectly fine (new) then the usual suspects are the alternator, starter-motor or anything else that has a direct live connected, such as alarm or HU memory...

If you have or can get a multimeter then remove either battery lead and connect it to the battery (one lead still connected)...

... Now pull each fuse in turn and check the meter until the result changes/rises, this gives you the component associated with that fuse thats causing the drain !! ;)

      BWM 216D F46 Issue.

      Hi Daven, Test for the warm welcome. I be always doing service according to the bmw specs. I have deleted all the codes and go for test drive with my mech, the turbo was not kicking in and even at P position, revving the engine, the turbo just do not kick in. Of cos they would recommend what to do, but I am jus praying hard that it could just be the Actuator issue.

      BWM 216D F46 Issue.

      Hi Murphy Welcome to the Forum While Diagnostics are an immense help they only tell part of the story I would delete all codes then run the Diagnostic again to see what comes back. At 175k (you don't say what the service history is) I would not be surprised if the turbo and turbo actuator were getting really tired. A rebuilt Turbo and actuator plus either a thorough clean of the EGR system would work wonders I should think. Sensors can be tested and or replaced if needed If your not a fan of DIY then you need a conversation with your Mechanic to work out the most economical route Good Luck Dave

      BMW M135i 2020 Ticking / Rattling noise when accelerating

      Hi Niall Welcome to the Forum As your car should smooth and quiet some things to try in order to narrow down where the noise is coming from First is it quiet and smooth when stationary engine running, if engine revs are increased is it still quiet and smooth. If it is then that rules out belts tensioners or pulleys. Last make sure nothing is touching the engine fan Next drivers wheel off and check for any loose under guards . While the wheel is off check the back plate and calliper are the pads loose/rattling. Fiddly but check at the back of the hub that nothing is caught in the reluctor ring, last spin the disc by hand and listen for any noises from the wheel bearing Good Luck tracking it down Dave

      BMW M135i 2020 Ticking / Rattling noise when accelerating

      Hi, I've just purchased a 20 plate BMW M135i. It's really nice, everything is in good condition but the only thing that's bothering me is there's a tapping / clicking / rattling noise when I'm accelerating coming from what sounds like the engine bay somewhere near the drivers side front wheel. I have had it in the garage and they said there's absolutely nothing wrong with it. I'm just wondering if anyone else has had the same issue, if so if you had managed to work out what was causing it and if required what was done to fix it? I don't think it's anything major in terms of the engine or anything failing. It's more just irritating, so if I can fix it I will do. Thanks, Niall

      I am looking at buying a 2014 135i anything to look out for

      Hi all, As you can see i am new to this forum. I am looking at buying a 2014 135i auto. Its got FSH, totally standard, with 77k on the clock. The guy who is selling it has receipts for loads of preventative maintenance, coolant, oil gaskets etc. Does the gearbox need servicing? if so, does anyone know what the cost is. Thanks in advance.
