Re: '84 633CSI High Idle

Can't you do a simple resistance check across the terminals of the temp sensor that you think might be faulty?

Re: 635CSi hesitates

So I’ve purchased fuel pressure tester https://www.amazon.com/dp/B07S9ZJPZ5/ref=cm_sw_r_cp_tai_ufNbFbW74MERA And checked the transfer pump (the one that sits in the tank). I jumped fuel pump relay, and the pump itself seems to work. I mean it’s able to pump the fuel without any load, to the bucket....

Re: 635CSi hesitates

The battery light will come on when the engine idle drops (hesitates) because the alternator is not spinning fast enough to feed the circuits. I guess what I'm looking to establish here is whether what happens is the same of in some way different to what would happen if you briefly turned the ignit...

Re: 635CSi hesitates

The battery light will come on when the engine idle drops (hesitates) because the alternator is not spinning fast enough to feed the circuits. But in this instance, while the hesitation is occurring, the engine will surely be rotating at well above idle, and yet the ignition light still comes on. I...

Re: 635CSi hesitates

You need far more competent people than me to comment, but the fact that the ignition light illuminates has got to be significant. But you also say that the dash "flashes". Can you elaborate on that please?

Re: Removal of auto transmission cooler pipes from the gearbox end.

And to finish off this thread.... Both new cooler pipes are not on the car. It was quite as easy as I expected to get them to fit such that the small securing brackets could be applied, but I got there in the end. One thing that was a bit surprising is that as supplied new by BMW one of the pipes wa...

Re: Memory Seat Controller Bypass?

Looking at RealOEM, it doesn't seem to offer two versions of the control unit depending on whether it's for the driver or passenger seat. My pretty clear impression is that the motors will run until they encounter resistance from the mechanical part of the seat being at the end of it's travel range,...

Re: Removal of auto transmission cooler pipes from the gearbox end.

Quick update. Both pipes are now successfully disconnected at the gearbox end. With the sump pan removed it gave me much better access to the 22mm nut at the bottom and I actually used an old but very trusty adjustable spanner to get enough purchase on it to start the undoing process. The straight c...

Re: Removal of auto transmission cooler pipes from the gearbox end.

FYI, I ran into this issue with my e28: The current replacement hose from BMW uses a newer style connector at the transmission meaning you have to use an adapter. Which decreases the amount of clearance you have in there to a nearly nearly unacceptable degree. Real knuckle buster. In hindsight, mig...

Re: Removal of auto transmission cooler pipes from the gearbox end.

Hi Phil, I remember this nut being a complete sod. I found a good quality 22mm open spanner and cut the other end off to allow a cheater bar to fit. If the nut rounds off you're in trouble, at which point cutting the pipe off becomes a more attractive option! I'm sure I have a spare filler pipe in ...

Removal of auto transmission cooler pipes from the gearbox end.

This seemed like a relatively simple task, but I soon encountered a bit of an issue with loosening off the connector nut at the very bottom of the gearbox casing. I don't have specialist tools so it was a case of trying to do it with a regular 22mm open ended wrench. Regular muscle power was working...

Re: Thoughts on a potential change...

I routinely pay for another car forum and have done so more than 10 years - not a problem.

I think an annual fee would be reasonable. Perhaps consideration might be given to having a free membership category, but with more limited access to certain areas or functions?

Are the cog mechanisms serviceable? I once had a complete cogs assembly out on the bench and recall it wasn't difficult to "adjust" the mileage reading, although I didn't try to take the whole thing completely apart.

And the stitching thread is also a different colour...

Re: HELP what is this broken connector? 1986 e24 635csi

That goes to the secondary crank position sensor, used only by the BMW shop disgnostic computer. If you trace out the wiring you'll find it goes to the diagnostic port and nowhere else. You can safely leave it disconnected or remove the sensor altogether. And isn't that a coolant temperature sensor...

Re: What are your views on spacers

Rule #1 on spacers: unless they are less than 5mm you MUST use hubcentric spacers. I have 25mm spacers on my 635 to bring the E36-offset wheels (et 45) out to E24 (et 20) spacing. You will need longer lug bolts. Make sure they are CONE lugs, not hemispherical lugs. I made the spacers myself. I am b...
