Hi All,

About 3 months ago I bought my first BMW, a 2005 320D SE E90. After filling the car full of diesel for the last time, I park the car on the drive and forget about it. About an hour late I go outside and theres a pool of diesel under the rear drivers side whell. I take the car back to the garage I bought it from to be informed this was a common fault on BMS's - apparantly the "seals" can go which results in diesel leaking. Anyway, they "apparantly" change the seals and it's been fine - up until this evening, when again I fill the car diesel - only to go outside an hour later to find another pool of fuel under the car - same place as last time so I'm guessing it's the same problem. I've taken care not to over fill the car as I was told this could cause this type of problem??? Anyway, any ideas why this keeps happening? Is this really a common fault on this model? And any ideas to a solution???

Thanks a lot

Cheers

J

Seals my arse. It's the plastic breather pipe, very very common problem on the E9X. I think there was a recall, contact your dealer to check. It rubs on it's mounting strap and wears a hole/split.

Only happens when FULL , so either get it sorted, or don't fill up to the brim!

2006 E90 320D - Diesel Leak when brimmed

wife's car just done it twice, local dealership pretended that it must be the grommet come out where it goes through the bodywork and wanted to charge 5hrs labour to drop prop-shaft, exhaust & fuel tank.

Both BMW UK & dealership telling different stories on why it is nothing to do with them and they have never heard of it before etc etc

car is 5 years and 2 wks old and had one service non BMW and this means BMW UK saying nothing to with them although how servicing would have spotted this I have no idea. Apparently this is a very common problem that happens when the breather pipe rubs and wears on the mounting strap. It was redesigned for later E90 so clearly is a design fault.

Lots were fixed under warranty so they DO clearly know about but both are just playing dumb which is very disappointing for a marque like this :frown

E9x are prone to the breather pipe splitting, most common is the 2.0d.

Its a tank down job & is very awkward to refit the new pipe.

Mine does it. I make sure that I always stop filling at the first click (made the mistake of filling it right up at first and it leaked a load out then). Seems to minimise it for me.

I enquired about it at a BMW specialist, and he said either don't fill it up as much. Or it's about £25 for a new part, and 5/6 hours labour for it to be done. So probably around £3-400 to be fixed. Have to drop the tank etc. to fix.
