Hi, Just a quick note - I had a n intermittent fault on the main sender (mine is only 1 x sender). To remove the oval shaped tube I drilled holes in one edge of each crimped recess. I was the able to insert a small screwdriver and prise the remaining crimped section proud of the top housing. The tube slid off really easily and there was sufficient material left to re-crimp once done. I was able to clean the inside with brake cleaner aerosol and took some very fine grit paper to the wiper contacts on the float as well as the empty level switch contact faces. Back in the car and all looks 100% again.

Hello brother, I have a problem with the fuel gauge in my car.e30 The fuel gauge is random and not correct at all. Sometimes the fuel light glows even though the tank is full. Can you help me solve it?

Thank you for this information! you are the good type TH-camr really helpful 🙏 maybe you can help brother.. I have a bmw E30 but I have swapped the engine to a Nissan SR20 DET and I need to feed a signal to my tachometer do you know from where I can get my signal connection? Is it from the coil signal wire or the injector pulse wire? I have no idea how to get a signal.. maybe both coil to pin 7 and injection pulse to pin 11? Please advise 🙏

comment tu récupères le signal du compteur et ce que tu peux expliquer avec un shema ou une video ??

Great video. There is a way to replace those 2 thin wires. Nichrome wire that's found in hairdryers, modern heaters, should do the truck. If you apply tension with a snipe nose plier and solder, you can be successful. You will need someone to assist you, four hands. Some of the E30's needs a full tank for the sender to work. Mine does that, ensuring that I had a full tank all the time. As soon as the Guage drops, I fill the tank up again.

hi! I have a question, is it possible to connect tachcometer direct to ignition coil for get signal?

I have a 1986 E28 518i with a 70 liter tank. When I fill it up it actually shows just 40 liters on the guage and starts showing empty when half of tank is gone. Have you ever encountered this? Any ideas if that unit is fixable? Thanks.

it is really helpful, i wanna try it myself and maybe try to buy a cheap multitester meter, but how do i set the multimeter?

1 level is 55L and 2 level is 63L(55L+2gal res)?

Thanks for this. I have a 1988 320 made in October delivered in November. It has a 63L tank - I didn't know some earlier ones came with 53L that might have given us range anxiety ;) Now I have a jumpy fuel needle (a bit like evanarends7825 three years ago) but mines is showing 1/4 full to empty when I think it should be fuller, but maybe some leaked out or evaporated!? Maybe the sender is wrong and it is 5/8ths, hmmm. Time to go in there with a multi-meter. Update/progress: So, I lifted the rear seat base and the sound padding to find the oval (R/S 4#philips2) and round (L/S 3#philips2) covers, removed them and...tested 66ohmn and 75ohmn steady and when I reconnected fuel gauge steady BUT when I banged the floor the needle flickered. I pulled two wire connector of the second (L/H) unit and popped in two wood screws to make contact, and banged again - needle solid this time. So, my fault lies in the second (L/H) fuel gauge. I know what AUF and ZU mean.... they mean Oh! F~~k! the O-ring seals are shot/flat/cracked. Sigh! OK found genuine seals and filler cap seal on eBay. The central rod was quite rusty - problem with ethanol in fuel methinks - cleaned with knife, 280, 400, 1,000 and 3,000. One pass of the 3000 on each side of the two wires and crossed fingers. Fuel needle steady for now, but perhaps should replace the rod with stainless steel rod?

This is awesome. Appreciate you sharing this.

What connector and pin controls the speedometer (how fast type traveling) Do you have any tips on how to test the speedo works on the cluster?

Can you Connect the temp gauge direct? Or do you need the board

name of the city bulbs ?

Very good...congratulations well explain

What glue do you use to reseal the pixi glass?

I think I got another e30 treasure channel!🎉

Good info

How u test it?

Please specify, "Special resistance wire". Thank you

I’m doing a early to late fuel tank swap . I’m about to wire in the secondary (driver) fuel level sender . I would just splice into the green/brown wire which is labeled (G) on your diagram for the gauge and wire it over to the driver side level sender on both connectors ?? That would be in series ? For anyone doing this you also need to have a late model fuel gauge(63L) in the cluster because they are 120ohms and the 53l fuel gauges are only 60 ohms .

battery cause the malfunction with time they leak acid better to remove them and the board will last for ever

i have to know how the hell you got it out

Hello, please share steps and equipment to create this test station.

How can I remove cover of unit

السلام عليكم اذا سمحت كيف يتم توصيل اسلاك عوامة خزان الوقود لمرسيدس ١٩٠ بالقاعده السفلى او رسم الاسلاك من الأعلى إلى الاسفل وشكرا لك

Interesting, can you list parts numbers to do this swap please ? I guess it's for 6 cylinder E30s

👍

Awesome video! Thank you for taking the time to explain and upload for the new owners. This video really helped me 🙏

Thank you very much you helped me diagnose and fix my problem.

This was very helpful. Thank you!

Thanks! Very Helpful.

Damn people are going to be selling e30’s with like 5,000 miles now 😅

A very helpful video on this topic; meticulous and detailed. Thank you for taking the time to post it. Good to understand the electrical circuitry schematic. Cheers!

How can we do this? Looking for a bypass, thanks

What guage wire does the unit use?

I seriously never understood why that cluster needs batteries since it has no clock and no digital quilometer/miles

Welcome . I have a problem with the rpm gauge and throttle gauge. Sometimes only the rpm counter works. The battery has been changed. And the problem still remains

how did you remove the aluminum enclosure on it?

Hi, great video. BMW E30 318 cluster heat gauge is not working. Any suggestion on what to look out for? How can I calibrate a tach for 6 cylinder?

None of mine is working. Wires were vandalized during some body work. Can they work again pls help

That looks cool

Great information 👍🏻

Hello. Do you know what wire is used on sending unit. So I could replace it with the same resistance. Thanks

Super job ;)

a source of supply would not be bad comes really cool

Awesome

Felt like I was at a mechanical school. Thank you for the awesome academic elucidation of design and function. It gets easier when one knows design to repair it ! I have an E23 BMW 735i, I think it shares same design as the E30, with non- functioning gauge. I will attempt following your lecture, to repair it. Sonny

Hi, How can I solder back the thin wire to each contact? It seems each contact point has some kind of resin, so I couldn't solder the wire with a regular solder iron and soldering tin
