Hello. Are these error free or have built in resistors? Looking to install in a 02 BMW 540i

They are error free, however I would not use them for turn signal bulbs unless you add resistors. I use them for running/brake lights with no issues. They are extremely bright and look good on my car.

Any good? I am not sure what you want to know. They are Bosch sensors. They are (to my understanding) OEM. As long as you buy the correct sensor (up/down stream cabling is of different lengths) for the correct placement/problem, they work fine. I purchased two upstream pieces because they were due to be replaced. I had gotten several codes to that effect. No codes of that type since.IF you plan on a downstream sensor resolving 'inefficient cat' codes..you will almost certainly be disappointed. The O2 sensor is not likely the cause of those codes. Such codes are MORE likely to be a cat failure: Particularly the left (driver's side) cat on an E38. Any good? I am not sure what you want to know. They are Bosch sensors.

I have these installed in my 2013 M3 and I have not seen an error message ever while using these.

I had no issues with it in my Lincoln. The most common sex is a load resistor, across the positive and negative wires. the plug

They will work, but blink like twice as fast. If you want them to remain normal speed you need load resistors.

Do not buy these for any BMW... I bought them because they are supposedly error free... and the same day i installed them it gave me an error code... don't buy this garbage.

Surely a connection or the configuration is wrong, they worked well in my car, not sure what's the problem on your truck body, sorry!

Yes. My car required the resistors for these bulbs. You can find them on amazon as well. Just search for "resistor led" in the automotive section. However I was told that if you have a good OBD2 diagnostic program you can go in and change settings so that you do not need the resistors. (I don't know how true that is.)

if your vehicle is fitted with the standard 16 pin plug i cannot see why you should have a problem. my friend has a bmw and he is also very happy that his 3160b tester could identify his vehicles problems and that he could reset the vehicles computer.

Same here. Its a simple install. Plug and screw in. If you try to reset the DTC it will only come back on. Bosch o2 sensors fixed the issue. Don't know what the deal is with these. Some kind of defect I think.

I'm pretty certain switching from any incandescent to LED is going to bring up errors due to the change in electrical flow. You can either try finding a set of LEDs that have the proper spec resistors built in that you're looking for (expensive), or you can buy just the resistor, and wire it up in about 20 minutes (relatively not as expensive). I have a set of these build on Honda Insight and they look great. The car just doesn't have a plate light error, so that was a null factor.

These plugs did not fit my car. According to the mechanic the plugs were too short. My suggestion is to call or visit your local bmw dealer and give them the last 7 digits of your vin number. The parts person can provide you with the actual OEM part number. This way you can locate the exact part online at a cheaper price.

I dont see any reason why a resistor would be required. They are 12 volt bulbs. I simply installed them into a boat 12v light fixture, replacing the original 12v incandescent bulbs. Although they are not as bright as the original bulbs, disappointing.

I use these on every installation I do and I've not had to change out the flasher relay yet. I've not experienced any issues with these load resistors I use these with confidence every time with every install. ~Dubbs~

You need to buy separate resistors. I bought the putco ceramic ones with these. You need one per side. Keep in kind these LEDs are less bright than stock, but give the LED look(instant on off).

We installed it and it didn't make any difference. We removed it and put the old one back. I should have returned it but kept it just in case the original resistor completely dies. Sorry if that doesn't answer your question, but that was our experience.

Hi I think you should go to a dealer and check it out, Quality? Company reliability is none. I wouldn't even bother, just going to waste your time.Sorry, but I have dealt with them, Been There Done That!
