I have come into ownership of a 316 1.9 Sallon, BMW build date Aug 2000 on an X plate.

When i first got it home i lifted the bonnet and noticed that the pipe to the thermostat from the radiator was stone cold whilst the one to the expansion tank was red hot, and there was no heat coming from the heater. been a tale of woe since............. can't seem to bleed it, going sort of crazy

Water-pump or sticky thermostat...

I have 1999 323 seci and so far have found it very reliable.

like other people i find the central locking and window drop tempremental on the pasenger door.

If I had to complain about the car it would be the tendency to rust on the wings especially the arches. this is a very common issue with the e46 as many other cars have the same rust spots

I had issues with my 330Ci M-sport (steptronic) stalling when pulling away, the revs would drop off as you touch the accelerator. turns out the crank shaft sensor was loose. not a clue how, to minute job to clean it up and plug it back in! drives like a new car now.

E46 318i SE July 2003 (face lift model I believe) 4 door, 85k miles. Had it a month and knew I would need to spend money on it as it was cheap for the miles and condition! Here we go then, these are the issues I have discovered in the last month...

* rear offside light warning on on dashboard when bought (but off now!). [Light came on again. Husband fitted new light cluster which did not remove the tell tale light immediately. He also said there are rusty connections. Pleased to say light has now gone off again so not a problem at the moment]

* driver side front window works on the key but not on the centre console button (have already had some advice on this one - thanks guy). [Husband fitted new switch on centre console - a 5 minute job 1 and it now works perfectly]

* trip meter reset does not work

* red battery warning light came on twice - checked out by RAC and no problem with v-belt or alternator. Has not happened since.

* red/amber brake warning light and 2x yellow tell tale lights for ABS come on (tends to happen in rain/wet conditions?) - radio often cuts out/goes off or crackles/quietens at same time

* airbag warning light partially illuminated

* Air con is not cold - may need re-gassing. [Not a regassing problem - have had it looked at by an air con engineer who tells me it has plenty of gas. May be a compressor problem (hope not - expensive!) but suspect it may be a control or temp sensor fault. Diagnosis and resolution in progress]

* Exhaust mounting loose - rattles. [Fixed by local garage - mounting had rotted. New one fashioned and applied]

* handbrake needs adjusting - holds right at top of reach. [Common BMW problem. Handbrake adjusted by local garage and now holds after only 3-4 clicks]

* dipping near side mirror does not work (not sure it should?)

* I'm sure the engine sounds rougher/noisier than it should at speed. Sounds ok at low speed or when idling at rest. Could be road noise but unsure

I just wonder wether some of the issues are basically electrical ones (ie most of the stuff relating to non-working electrics and dash board faults/tell tale lights???)

Also can someone tell me what oil I should use - the manual only recommends BMW oil but I'm not made of money (especially given above fault list!) so need to know what common or garden oil I need to buy!

[My brother also looked at the OBD codes - will post these somewhere else as I need some help on what they mean. No engine faults, no air con faults but there are airbag and other fault codes]

Hi,

Just thought i would ask this for a mate. He has a 2000(or somewhere in that region of time) plate E46 323i. When he does long distances at speed He gets out the car and smells hot/melting rubber on the rear passenger side. He has had it a BMW specialist who cant figure it out. So has anyone here had this symptom and found out what it was? There isnt any wear on his tyres etc. Possibly a rubbing brake heating a wheel and in turn heating anything attached to the wheel?

Im outa ideas :)

Hi you all,

Most common problems on the 330d and the 330Ci are the brake pipes that go

over the petrol tank.Why don't they teach mechanic's tocut pipe before tank and push

new piece over.Also changed front suspension rubbers on both,and tend to burn up front

pads. Other than that I love them both.The 330D has low profiles so sticks well on bends.

The 330 Ci has normal rubber but faster pick up on higher gearswhich means I have to drive

itround bends. Have changed filter on Ci to K & N and added chip.Filterjust needs a wash

out now and again,so makes it much cheaper.Have also changed spare for a normal wheel.

Thats me lot so far.

I have only had my 3 series 318i se touring since Nov 2011. The problem i have had is the handbrake wont hold on moderate slopes. I went to BMW main dealer, who found the brake shoes were severly worn and needed to be replaced. Now the handbrake works great. Also the electric radiator fan only works on fast spin. Not to bad for a 10 year old. Since then rad fan replaced, expansion tank replaced. small split leaks when hot. Front near side suspension bushes replaced. Rear near side coil spring replaced (spring broken). Rocker box seal replaced. Sump seal replaced. Long time leak. Drivers airbag module replaced, under national recall. Car now 12 years old, most things are age related. Next year car will be a teenager 13 yrs old, what next ?
