Water in driver side footwell
Hi all. I know this has been covered loads of time. I've done plenty of searching on the forum and the car has been to an independent specialist and bmw. Both have fobbed me off and I'm pulling my hair out (what's left of it).
Car is a 2013 F31 330d I noticed water in the driver footwell a while ago now and thought it was either the grommet or vapour barrier. BMW confirmed the grommet issue had been sorted previously. I've had both door cards off and there is no evidence that the vapour barrier is compromised in any way, only small gaps are around where the wires protrude. Other than that it appears sound. There is also no evidence of water underneath door card. BMW specialist did a "water test" which meant a hose drenching with water with a mechanic inside looking for any leaks. No joy. BMW did a brief check when it was in for a recall and found leaves and debris in engine bay. Cleared it out but problem persists. The water appears in both front and rear passenger footwells depending on which angle it's parked (obviously water finding its level). However when flat it appears to be more in the rear of the car than the front... Also, on a side note. When checking door cards my battery has died on two occasions. The doors have been open for about 30-45 minutes. Surely battery shouldn't die this easily? Any help would be massively appreciated! |

They do still fail and more so if the area is gunked up and causing the water to ingress into the car Do you have a sunroof at all? It's deffo not a vapour barrier issue if they're well stuck on and it's bone dry; you'd know if it was those as they'd be flapping about And no your battery should not be draining that quickly; but how old is it and have you checked the voltages to see where they're at with a multimeter? Need to be c12.4v engine off/car asleep and c14.4v when engine is running If it's old'ish and not up to those voltages; time to replace it

I don't have a sunroof no. I'll look in to getting a new battery too. Not sure how old it is but it's at least as old as I've had the car, nearly 9 years! |

Not sure where it runs on the F3* platform but the air conditioning drain tube on other BMWs runs through the passenger area behind the glovebox. A blocked tube will dump the condensate all over the floor.
Obviously it will only make water when the a/c is on and the car is running. A little water goes a long way inside a car. Ask me how I know! |

Windscreen seal is a common issue of moisture inside the cabin. To check this pour some water on the windscreen and see front if its dripping somewhere.

I did my FiL's F10 530D in about an hour with a bit of lost skin etc And yes; you deffo need a new battery (remember it needs to be registered to the car if you replace like for like (or as near to it) If you get a whole new different spec battery it needs to be coded to the car and then registered I fitted the Exide 95Ah AGM battery from Tayna to my F31; as close to OEM as I could get and registered it to my car using my Creator C410 OBD2 code reader https://www.tayna.co.uk/car-batterie.../?gad_source=1 This is all you need as a battery; you really don't need to pay any more than this TBF Not sure where in Lancs you are but if you're local to Preston and want it sorting, drop me a PM

Some of the videos showed the grommet being accessed from inside by removing lots of trim etc. Others were through the engine bay. Any experience as to which is easier? Also, are there grommets on each side or just one? Should I be looking on passenger side of engine bay? |

Also. How come the water is finding its way to the other side? |

Water in a car can get everywhere; it could be tracing down behind the dash and getting in that way etc... Generally it goes to the lowest point (rear passenger footwell) first and then can spread from there My FiLs F10 was absolutely sodden; took weeks to get it fully dry But this is only guessing currently that it is possibly the grommet; seems everything else has been checked
