    Found out that L/R wheel sensor works the speedo. The harness runs along the left floor panel along with the L/R top interior light harness. The light was flickering (short) this is not fused and goes directly to the general module below glove box. The light was at one point changed & clip was broken holding the bulb & therefore was touching the GND through the steel plate behind the bulb, & as result melted all the wiring together up to driver seat. repair wiring and all stated to work.

I have a 1996 740 il bmw my speedo and raido works every blue moon. I no it's a wire problem, any idea on where to start?

You either have a loose wire or a bad wire shorting out. The only way to tell is by checking all the wires with a voltage meter. They are probably on the same circuit. Check for loose wires first. If you can't find any, check the wires. Make sure all the grounds are grounded. They are the black wires. It may just need to be tightened. You will probably have to take the dash off to get to them or maybe just the radio. If you need anything, let me know. This website may have a diagram for that. Thanks for choosing FixYa. If you need anything, let me know.

Hi, I have a volvo 740 made in belgium 1991 model. The speedomete spent a few months fluctuating wildly, sometimes working well, sometimes not at all, sometimes stuck on 140 km per hour. The odometer...

There should be a speedo sensor on the transmission somewhere. I don't know exactly where it is located. I believe your speedo is all electrical so the sensor on the transmission sends a signal to the speedo head. You can go onto some parts stores websites and see if one is listed for it, if it is, I would try replacing that first. I don't think the part should be more then $50 or $60 but you never know with Volvo. Good luck.

Bmw 740 il key broke in half at remote part car

Yes it is, but just having the key near the ignition is enough to start the car. If you can turn the ignition with the broken key, hold the broken part in your hand and see if it will start. Hopefully the chip isn't damaged. I know that when GM keys are replaced, they glue the old key under the dash to make it work. Hope this helps.

330 diesel 2003,abs lights come on and the speedo stops and starts any ideas???

Wheel speed sensor fault. The sensor also has a bearing on the speedo. They are VERY common. Get an autostore to plug in and give you the code to work out what sensor you need.

My check engine light came on in my 1997 bmw 318i e36,the codes were se and 07. can you tell me what the codes are?

The codes are very extensive and tobe honest with you, Too much to even start to comprehend. If your check light came on, Changes are good it was triggered by an oxgen sensor. The vehicle can still be driven, It just means your emissions are incorrect. Not to worry, but have it verified which sensor and have it replaced. not too expensive. good luck, Ned

Bmw 328i speedo problem

These cars have expesive components so I would bring it to the dealer to confirm the speed sensor located on the transmission is in fact defective or faulty before I purchased the dealer item and replaced it.

1997 bmw 740Il-116844 check engine code

How does the car start and run? If Ok, I would make sure the computer housing is properly grounded. Grounds are normally the problem when getting wacky readings.

I bet the car runs fine, Correct?

Good Luck

Speedometer erratic/intermittent

I don't know what is causing this problem, but I know phil140701's answer is completely wrong on two counts. First, 740 Volvos starting at least in 1986 have electronic speedometers and no cable. There is an electronic sensor on the differential which sends a signal to the speedometer cluster. Second, if it were strictly mechanical with a cable then the voltage regulator could have no effect on it at all.
