E46, 318i, central locking dont open on hot days

[Rishaan]

aaaarrrrgggg...... Guys, help me out here please, i have this problem for 2 yearz now, the darn car does not want to open with the remote, esp on hot days,,, i have to manually turn the key for the driver, but no other door can open.... what could it be ???:argh:

I stand to be corrected but im sure there must be a Master central door lock actuator (right hand side) in these cars... normally if this pops the other doors wont work.

As i said i stand to be corrected. :bangdesk:

Had this problem on my E90. Had to replace the door locks, was done under MP

perhaps i shoud just have a look at all the pumps in the doors and the boot? maybe one of these are kicking out this problem..... but as i said it works perfectly, except on hot days..... my girl is soooo not up for the jumping over seats

Sounds like a small problem, but hard to find. If you say heat plays a role then I would say a crack in something somewhere is probably causing it...

I have a similar problem on my e46 318i, hot days the car struggles to open, and when it finally does the other doors won't open, even if you pull the handle from the inside the lock pin pops slightly out and then retracts again..

I have the same problem with my E46 323, on hot days but has happened on cold days. Any takers as to the direct and/or indirect cause of this?

the cold weather of late should help:fencelook:

On a serious note, check your door acurators.

I found in my white e46 on very cold mornings only the driver side doors sometimes fails to operate with the remote. But once opened once manually it's fine for about a week or so.

When I have a look and find anything I'll post back...
