How to Fix 2004 Volvo XC90 Sudden Loss of Power. Less than $15 

From Nigeria, had mine used xc90 for years, No mech could fix it. Haven't driven it for 20minutes without this problem. Can't wait to try this out.

Dear 33 Electric, firstly greetings from UK. This is one of the most basic, useful fix videos for xc90 on RU-vid. Just the other day I drove home from work, no problems at all then went straight out a couple of minutes later and pressed the door button - nothing, so thought it was odd, opened it with the key then got Airbag & brake failure warnings then dash went blank so I drove home in limp mode. Put a diagnostic tool on it & cleared codes it's been fine since but guess what it was like 80°F so I think it's just overheating. I'm going to put a fan in mine. So thank you very much👍💰

I've driven nothing but Volvos for decades. They all have the same problem...overheating electrical components, mainly relays and computers. I learned how to take relays out, check out the solder joins for cracks, retouch them, take the covers off carefully and drill them full of holes, and put them back. This way the trapped heat can escape. I don't buy new ones unless I have to. I also pull out fuses and sand them off, they can be full of corrosion. If you are running A/C, you are making engine run harder and making it overheat since it has to turn compressor as well. I usually lower the windows and let the outside air in. You would think that by now Volvo would fix this, but they won't.

Thanks for this video. Once my xc90 drives for about 20 kilometres, it loses power and starts to hesitate when pushing down the gas pedal. Sometimes, the dash just goes blank, and the entire system just underperformes. I can't wait to try this. Much love from Nigeria 🇳🇬 ❤️

I had the same problem in my 04 s60. I removed the CEM on pulled the metal cover off of one of the components and wired up a computer fan. The metal cover trapped a huge amount of heat...it’s been 2 years and still works great. I’ve heard of people using tiny heat sinks, also.

Hi 33 El, exactly where do you unscrew the panel below the steering to access the CEM? Sorry for this basic question bit I'm not familiar. Thank you and I appreciate this helpful video. Yes this problem has baffled even Volvo technicians as it comes out sporadically.

Thanks for the info. Very informative 🍻

Brilliant! Thank you for sharing. As a related note, have you secured the upper CEM unit from water intrusion from the exterior? The unit is accessed by removing the windshield wipers and wiper plastic piece that runs along the bottom of the windshield. The factory design is a super flaw and can easily lead to corrosion do to water intrusion from not only aging weather seals but also a fundamentally poorly designed protective housing. Cheers.

can it be moved over a little and the metal shield removed to make sure it won't get wet and reduce heat ?

hello, can someone tell me where is the 2004 xc90 idle air control valve?

Thank you this helped.

1. Please, what diameter fan did you get? 2. Also, you wired the fan on a switched unused fuse, right? 3. When you had the issue, did you get a code? Thanks for the awesome video!

Yeah I was out driving my 04 xc70 and my cluster went completely out. I’m gonna look into this. Car was driving nicely before hand tho

I hope this work for my 2004 volvo xc90 thanks.

YOU'RE AWSOME ! ! ! Thank you...🥰

Thanks for posting…. My 2007 has stopped running . Suddenly for no reason 5 times in 3 years. 3 times on freeway. 2 times on surface street. No codes starts immediately after coasting to a stop( without being killed by other drivers…) Hoping this attempted solution will fix mine.

You noticed everything apart from the fact the steering wheels on the wrong side I’m just kidding I’m gonna try this tonight thankyou ☮️

This is very interesting.... My volvo only stalls when warm as well runs fine otherwise. I have the 3.2 (08) i will definitely try this makes sense. (Found issue. Fuel PSI cut when temp got too 190 degrees . Fuel pressure sensor is the issue. Took weeks to figure out .

You are the men. Thank you so much :)

Xtreme cold will make s60 goes to limp mode?

Awesome! Thanks for sharing!

Computer fan worked for me and heat sink

My Volvo got me stressin

Thankyou very much

Hi, did your car went into limp mode when the CEM is overheating?

Wow amazing

Did ya have codes come up on dash ?

The cem electrical is most likely due to water.... From rain leaking down side of windshield.... If it doesn't get channeled out correctly, it drips RIGHT ON TOP of the cem..I woke up one morning to lights blinking, horn honking..... Pouring down rain outside.... Totally fried the cem.. Found some guy on eBay, paid $200 for them to program my donor cem and make an extra key.

2009 Volvo doing the EXACT same thing!!!!

👍🏼👌🏼👋🏼

We have a 2007 xc90 random stalling on surface streets at low speed, on freeway at high speed. Sudden loss of power (motor dies) pull over without being killed by other drivers… put in park turn ignition off. Immediately start and drives like it never happened….

My xc90 2005 is overheating, what do I do to fix Fuel consumption is high also , what to do?

❤

What can exactly did u get

Where can I purchase the fan?

You butn on day xD

For the love of GOD don’t buy one of these cars
