What made the relay go bad?

[@Fr33dom89]

So what does it mean when these sytmptoms are backwards, when the relay is in it has no lights and nothing happens and wipers come on, then when I pull the relay out the lights come on and the wipers stop

[@heribertofigueroa271]

😊

[@allmycarsisbroke]

Oh my God, bro. I have had this car for less than 3 months and I have searched for so many things, and 95% of the time, one of your videos is the top result. You are a fkn hero. ❤️

[@carlitosdos9734]

Hey, a $39 CAS relay fixed my problem...You just saved me thousands of $$$... Thanks for the info, great video, your are awesome!!

[@louihuntclub7215]

Where did you buy it from?

[@ivansaavy6800]

Same here! My car would start but the relay was shorting out causing the dash to go crazy(rpm meter, mph, abs, airbag lights all would flash) car locks, windshield wipers, trunk wouldn't open. Any shop would have slayed me for real. Thousands saved. Thank you for sharing work!

[@simeongovender5615]

Thanks a mill. I replaced that relay and car started fine. That relay was hot when removed.

[@riftster313]

Hahaa! Man I love you guys' videos.. I didn't know about this relay until researching here. My problem ended up being the actual starter, which was easily swapped out (relatively).. But I now have an extra CAS relay in case the issue ever pops up

[@tebogondlovu3382]

Thank you for the videos you shared,i have a 2014 mini cooper s and am having problem starting it because the key fob does not turn the dashboard on so that i may start the car so am planning on taking it to the dealer to change my cas control unit if that's the problem because I've tried numerous attempts/methods but i failed

What causes the relay to overheat and wear out?

[@SpecializedECURepair]

So cool! Love what you're up to. I hope that we can collaborate soon.

[@edgaraguero1824]

Does this relay have anything to do with the fuel pump? I have already checked fuses and replaced the fuel pump relay and it cranks but does not start.

Thank you! I enjoy and learn so much from your videos👍

[@fener4587]

I just want it to thank you so much for your videos.I just bought a 2012 535 I.Car has Comfort access has well. I have 2 problems 1 car sometimes doesn't crank after pushing button few times then it suddenly starts . Sometimes I have to leave the car lock it and come back and then it starts after few trials sometimes starts the first time.I almost got stranded the other day car started after many push button no cranks.Idrive display showed ignition malfunction as well..I have new battery installed by BMW 2 Start stop button works most times.But sometimes the car will not start after a stop on a light and gear goes from D to Park, transmission malfunction light comes After that I have to push the button to start the car. Car may start the first time or after couple push start no cranks then Everything gets back to normal. when I turn off the start stop technology, car drives great and no problem.I think these 2 problems may be related any suggestions to solve them what do you think?

[@user-ht2xc8ne6i]

Hi, very nice videos, and they are very helpful! i'm wondering if you could welp me to diagnose my mini cooper. Same problem no crank, no start! the only thing the dash lights are not coming on. just once in a while they come on, but same issue no start. i have some code like A0A9 Cas fault, plus A122 and A123 Cas Hall Sensor Fault. the battery was dead so we change it and it starts having this issue. i will give it a try to the CAS Relay and see what is going on. what i will do also is clear those codes and unplug the battery and make the full reset procedure shorting positive and negative for 15 min +, and start from there. i don't know how to contact you other than this means. thank you Nick

[@dduktube]

I have replaced CAS module relay but still have exact problem. What else can it be? It behaves exactly the same way to the OP...have power in dash, lights, windows, door locks, fans, headlight...all works. I hear the fuel pump also kicks in for 1-2 seconds every time. Can it be stuck starter solenoid, starter relay or fuse? What else to check?

[@raeesgamildien4681]

Yo bro I have a similar issue when trying to start , but when I tried to kick start the engine doesn’t turn over at all , would the fues cause that ?

[@gustavomarcelo7250]

does the 2005 e90 320i N46B20 engine, have a starter relay?

[@richardpitzer9922]

You have two different videos concerning the same relay, one video is for the wipers and then the other is for the cas... is this a shared relay? I have a 2007 328xi. I'm replacing the safety disconnect and the intelligent battery sensor at the battery. When I removed the relay that was supposed to be for the cas, the wipers started going crazy...

[@Nolondo1999]

Same thing for me as well. Did you ever figure out what the issue was for your car because I’m in the same spot as you

[@clublength724]

BMW E90 would not start or sometimes start. It would also not release the car key. Wipers would go haywire and many fault lights on instrument cluster. i would welcome any advice. Thank you.

[@luishernandez4964]

my relay does not activate, where is this relay getting the activation signal from? I have been looking for a week now and can't figure it out.

[@yghunait6936]

New sub man thanks

[@coolwicia]

The car does not start, the starter turns. After inserting the key, there is no clicking sound as usual, as if access to the car was limited, after pressing the ignition, the lifter appears in red, the wipers turn on and cannot be turned off, and I could not lower the windows. Central works. After connecting INPA and ISTA, there is no communication with the car, INPA does not even show that the ignition is on. Disconnecting the battery for a moment did not help. I had something similar happen for the 3rd time - the car turned over but did not start, and each time I closed the car and put the controllers to sleep, it returned to normal. After a few hours I get into the car, put the key in and hear the click and the car starts. Bmw e90 2007 any idea?

[@justinekatele2061]

[@bluspirit81]

MY E92 320d GOES OFF WHEN RUNNING, ESPECIALLY WHEN I LEAVE THE GAS AND THE ENGINE LIGHT GOES ON. self I turn it off and on with the key ,it starts again without problems. the cause may be this black relay or the blue one in the engine compartment ???

Hi, i need help with my car problem, the problem is my car crank but won't start, i checked injector signal, there's no signal, i checked ignition coil, there's also no signal, then i checked all fuse and relay, there's no fault. After that i checked all the wiring on engine, there's no problem with the wire harness, lastly i checked the ecm/ecu, i bring it to ecu repair shop they checked no faulty and i pay charge for checking usd60, after that, i try to start again, its still won't start, then i bring the ecm/ecu again to the bmw agent for checking with charge usd100, they also said there's no faulty with the ecu/ecm. I checked the fuel pump its working, i checked the pressure of fuelpump its working perfect. I checked the immobiliser, also no problem, Im still wondering with the problem and why my ignition coil and injector no power and no signal. Fault code on obd is P0341, P101b and P1061 , i tried clear, after a few minutes its appear again, anyone know what the problem? My car BMW 320i E90 2006, engine N46
