Arata

Hey man thanks for heads up! Tried to send you a message but for some reason didn’t go through. Is the numbers right??? I’ll leave mine here. 0210786610.

Hi team. Hope everyone is safe and well. It is almost coming to the end of the year and I’m slowly updating my e30 and sadly my transmission started to play up. I have an intension of fully rebuilding it. But I was wondering if I can source a second hand one in meantime while I rebuild the current one. My E30 is 325i couple Mtech 2 and has a zf4hp22 EH. Have ordered a second hand one through trade supplier and unfortunately turned up with the zf4hp22 but for 4 cylinder one. (Bell housing is totally different so not going to work…) Is anyone have the transmission that I need that I can buy? Will check again with supplier for another one that’s right fit for my car, thought I’d try here. Please note: I have no intention of doing manual swap at this stage, yes it’s probably better but want to keep the car original no modifications. If you have seen my car in Chch you know what I mean… Part number is 24001216597. Thanks in advance.

Where did you get your aftermarket fuel tank from? I have decided to replace the fuel tank with new aftermarket one as it decided to run only 1/3 of power it should have. It is definitely the pump failing due to the rust still inside. I have already ordered new tank, pump, filter to get me going and see if I can repair the old one by cleaning again and sealing. Fingers crossed.

Yep trying to save the tank by cleaning but I might have no choice but to get a new tank if it does not work. Where did you get your new tank from?

Yep have previously cleaned thoroughly and made sure it was cleaned dry after. But yes that could also be the case. I might have to get it cleaned again.

Yep those are soldiered nicely.

Hey thanks for heads up. Yes the connector going to the fuel pump under the seat was repaired before so those are not moving freely anymore but I will double check. I’ll try get one from the supplier for the current one under warranty and hopefully it will last me enough till I get better one… if I am getting the walbro255 fuel pump is there specific one listed for E30 set up or any of them is fine?

Hi team. Arata here again with issues with my E30 (again haha). Believe or not I'm having issues with fuel pump(s) failing relatively quickly. From the previous owner to during my ownership, went through 4 pumps through last 3 years. First one lasted 2 years+. That time around the fuel tank was rusty which I did not clean that time. Second one lasted a week and died. Tested 12v directly and not even powering or moving at all. 3rd one and 4th one the pump was still somewhat working but not flow rate was down. (this time around the tank was taken out and cleaned thoroughly, no visual rust build up at this stage) First and second one was from trade me (nz shop), the other two was Icon series. Have already tested the fuel pressure regulator and is still working fine. Have replaced fuel filter frequent enough at the same time as fuel pumps, obviously with fuel filter facing right way of direction. I will definitely consider checking the tank and give another cleaning but just wondering those who owns E30s out there that have replaced their fuel pumps, which brand you guys used? Will talk to the shop to see if they can swap with new one under warranty but if the brand is the issue then I would get either genuine one or high performance one. Also wee question, what is the fuel pump check valve? Is this in-build inside the electric pump itself? Or is it the fuel breather? Some people suggested that put the check valve in the fuel line but not sure if that is ideal. Any suggestions or ideas much appreciated. Thanks team! Arata the crazy Japanese guy

I put 50/50 ratio and about 10 litres each. Soaked inside for 4-6 hours, and flip the tank upside down and soak further 4-6 hours.

Update guys. Managed to encourage myself to take the tank out and cleaned it during Easter holidays. The rust wasn’t as bad as I thought. Definitely needs another good cleaning with soaking in the solution but it came out much better. I used CRC Evaporust with distilled cleaning vinegar and was a good success of cleaning. I just had to keep rinsing and cleaning with acetone about 5 times fully till all rusts are gone. The photo of the bucket with rust was about the third time when I drained the tank. Also at the same time, I’ve replaced the flexi disc on driveshaft as i didn’t notice that it was far beyond cracking. Don’t ask how I’ve been driving with it like that condition for the whole time…

Thanks guys for suggestions. I’ll have a decent look inside the tank and decide what I can do.

Hey team. My 325i died on Friday night (some people might have seen me at Pak n Save getting towed haha). Did quick diagnostics while I was waiting for tow truck to come. Cranking forever and not starting. Funny enough I’ve already replaced fuel pump and fuel pressure regulator and other normal maintenance items so I’ve scratching my head. Got it towed back home, yesterday morning I’ve checked the usual things as it follows… All relays working. Fuse and relay for fuel pump is getting power while cranking as well as at connector end. I added direct power to the pump and I can hear the pump moving. Checked the fuel filter and it wasn’t the dirtiest as I’ve replaced about 1 year ago. But did some rust came out. So put everything connected again and disconnected the fuel hose to the regulator and injector rail, fuel not getting to the engine. So took out the pump again and this time I dipped in the fuel in the bucket and added the power directly, the pump motor moved but guess what, it’s back flowing from where inlet supposed to suck in the fuel to the outlet, this point I believe the fuel pump is damaged somewhat and I think bit of rust in the tank is the problem. I’ve already ordered the pump so hopefully I can at least test to see if anything else is the issue but meantime just wanted to see how you clean the tank inside. Any suggestions welcome. Thanks team.

Are you talking about the condenser fan? It is working as far as I know. I’ll give another look for the fan operation.

Hey Eagle, happy new year. That is correct, when the car is on and when I press the air con button on (or off) there’s no power at the compressor plug. Ok that sounds like another thing I’ll try. Thanks for advice.

Hi team. Dealing with my E46 hvac today. Basically the ac is not blowing cold, not even warm cold. Heater is working fine as well as blower blowing all speed. i have checked the fuses and they are fine and getting power, checked the relays behind fuse boxes and they are ok too. Now only thing is that the ac compressor connector is not getting power when the button is pressed. When I press the button the engine rpm changes, so I’m assuming that the modules are telling to the ac compressor to engage the clutch but no power. I’m assuming that the ac clutch is gone and needs new compressor. But I’m just wondering what’s preventing it from not sending power to the compressor, is it because it’s in the fail safe mode that the modules are not sending power on purpose, or I do have wiring issues? I have tried using the ac recharge can but according to the can and with the gauge telling me, unable to recharge as showing on red warning zone (70psi at low pressure) at needle pointing when the car/ac is on. Haven’t got to test the high side. What’s everyone’s suggestion? Thanks in advance.
