- This is a short video showing how we tracked down yet another battery drain on our R230 Mercedes SL 55 AMG. Once again we used a thermal imaging camera to quickly find the fault, but on this occasion, fixing it proved unnecessary. Simply removing the appropriate fuse and rebooting the module seemed to cure the problem in the short term.
Thank you for this helpful video. The 7.5amp fuse on mine was burnt.
Glad the video was helpful - I wonder what caused the fuse to blow? Mike
@@MikesMercsandothercars car was in a accident. Front passenger Seatbelt replaced. Was showing code for tele aid control unit. Changed this fuse and the airbag light went off.
@@Ayaz-popal Its great when there is a simple fix. Mike
@@MikesMercsandothercars 100%, it was actually my customers car. I've never worked on this vehicle prior, your video was indeed very helpful and I'm thankful.
Excellent diagnostics ! In addition I’ve found the cheap BM2 battery monitors a good way of monitoring remotely how quickly the battery may be discharging.
Thanks for your message - you have reminded me to explore the possibility of using a combined SIM based battery monitor and tracker. This would send a txt when the battery reaches s certain level and would be useful if like me your car is not stored near to your house. Mike
Thanks Mike. Another great video packed with info… Even if I’ll never have an R230, they are fascinating to watch 😊
We moved to Brazil at the end of September. Not a lot of 107 action here 😂
Hi John - you are such a jet setter! I think they still make the VW Combi in Brazil so if you ever fancy reliving your youth as a hippy, you are in the right place. Mike
@@MikesMercsandothercars Funny you should mention the Combi. Already looking and have seen a couple of nice split windscreen ones 👍🏻
Hi mike glad you posted this one cause I had /have the same battery drain and removed the 7.5 fuse which stopped the drain but also cut power to radio amp ,not ideal but effective,I would be interested to see a vid of phone cradle removal as like you I don’t use it .good vid as always on a great car cheers
Thanks for your comment. IF it was the phone module causing the drain, you might find that removing the fuse has cured the problem....at least temporarily. It could of course also be a problem with your Command not shutting down, Sometimes you can diagnose this by setting up an iPhone camera on a tripod and filming both the front dash and then the CD changer in the back and seeing if they do indeed shut off after 20 minutes - you'll hear it on the sound track of the video. Where are you based? Mike
@@MikesMercsandothercars I’m up in Aberdeen ,I have owned a 30,000 mile 04 sl 55 amg for the last 5 yrs with no regrets,your channel has been very helpful since I lost contact with a independent amg mechanic cheers
Thanks very much,
You are welcome - hope it helps solve any problem you may have. Mike
Hey there Mike. Nice to see another one if your videos. How did camping this summer go?
Thanks for your comment - good to hear from you. I haven't had a chance to log into your channel recently but I hope its all going well? We have had some amazing camping trips this summer in our little Fiat 238. It is still early days for that van and there is lots that needs to be addressed...welding....ball joints etc etc. It takes an age for parts to arrive from Italy! At some stage I will do a small video comparing the experience (and cost!) of a classic camper van vs a modern camper van. Mike
great video
Thanks. Mike
Hey Mike. Question about your 280 SL R 107. Do you recall where you got the mercedes red center caps for the mag wheels? I have a set of RIALS for my SLC so I am looking for a proper center cap. Thanks and cheers from Orlando FL.
Greeting from not so sunny England. I got those centre caps from ebay by typing in "mercedes center caps red" They were very cheap in both price and quality (£7.75 - I seem to recall) Having set that they never fell out and did enhance the look of the vehicle, More details at 3.08 in the vid below:

@@MikesMercsandothercars Thanks Mike!! I was a bit sad when you had your car stolen and basically destroyed. How did that end? Were you able to get the car back? I mean for parts?
@@frankbenz893 The insurance paid out on the red car and it went to salvage (see ua-cam.com/video/mFbYpF2zvs0/v-deo.html) After I posted that video, someone bought the car the next day...and just sent me a picture of the rebuild car. I may do an update when I get a chance to get over there. Mike
Hello Mike, long time subscriber here. I am (also) very familiar with this particular engine the M113K. Try to find out if the front engine cover oil o-ring has been replaced; it is a matter of WHEN and not IF, as well as the o-ring for the oil pick-up tube.
Here is a video showing the o-ring and the catastrophic damage it can cause.

Hello - good to hear from you again - its been a while! Ive been slightly distracted from my red 107 project with the Fiat 238 camper van project. Important to keep the family happy over the summer. Not sure about that engine cover O ring. What happens when it goes wrong and what are the symptoms of it going wrong? Mike
@@MikesMercsandothercars Depending on which of the two o-rings fail: 1) Complete engine failure (engine running without oil) OR 2) Oil and water mixing.

@@MikesMercsandothercars Just to clarify, the M113K engine is the one in your SL55 AMG :)
Mike my 76 fuse keep blowing what does # 76 fuse control as there is a dead shorts some where, do you know
Hi - what model car do you have and what year. In the R230, F76 generally controls the now obsolete "telephone systems/emergency" call. In other cars F76 is the vacuum pump relay fuse. Does your car have any faults or problems showing uip as a result of this fuse blowing? Mike
@@MikesMercsandothercars yes mike thanks for getting back to me, I have a 03 sl500 Benz and all of a sudden the sos and srs lights are on plus since I watch your post I learn that the fuse is the number # 76, mine blow with a dead shorts and the sos light switch above the dash has no current either so that’s what I am facing now
@@benaiahmusic Hi - so if I understand you correctly, you put a new fuse 76 in, turn on the car and it blows straight away?
If that is the case, I would say the most likely scenario is that you have damp/moisture/corrosion in one of your connectors.
Did any thing happen or get changed prior to this problem - eg I was driving in a thunder storm...I moved a seat...I opened the trunk etc etc
1. Check under the seats - any moisture or damp?
2. Open both doors and check for signs or wear on any of the wires or contacts
3. Check the front grill drain hole is clear. Sometimes the drain plug gets clogged and this fills up with water and overflows onto fuses and electrics. See my SL55 drain hole video.
Other than that, you might have to get an auto electrician to trace the fault. The thermal imaging camera might help to identify what gets hot just before the fuse blows.
Mike
@@MikesMercsandothercars yes thank you mike I did drive through some poring rain that night not sure what could have got wet but the fuse blow instantly when I put another one in so there is no fuse in now and the sos and srs lights are on, I would like to check that drain plug you spoke about and see if there is anything I can fine that is contributing to that dead short that’s going on, but you have a good idea of what is going on now, if there is anything else you can help me with to solve this problem please let me know thank you very much
@@benaiahmusic Start by watching the video below at about 1 minute in:
ua-cam.com/video/32TOT3YRMJo/v-deo.html
Pour some water down there and make sure it flows straight out and doesn't sit.
What country you in?
Mike
At the end, you didn’t find the problem 😂
Thanks for you comment - the camera found the problem at 2.12 in the video. It was the Nokia charging cradle. Thought I had fixed the problem, but it returned so I removed the cradle and all seems good now. See:

By a CTEK MXS 5.0 and hook it up to the 2nd battery in the trunk. The car can sit for months.
Problem solved.
Thanks for your comment. Yes the CTEK trickle charger is a great solution for those with access to power. My garage is remote and doesn't have power unfortunately so a trickle charger is not an option.
In my experience, many of the consumer batteries in the R230 are knackered because they have been left for a period of time at below 11.8 v which quickly causes sulphation.
I have also come across numerous cases where people have a parasitic draw without realising it - they just assume that the consumer battery runs down quickly. A good AGM battery with an 'in spec' draw lasts 2 -3 weeks.
I'm working on a lithium battery solution which integrates with the BCM and alternator. That is what this car needs...and what be installed if it was designed today. Mike
@@MikesMercsandothercars - Fortunately for me, my 2009 SL550 with AMG package has a CTEK MXS 5.0 battery charger hooked up to the trunk battery. Car has less than 18k miles on it and is garage kept with a car cover.
@@jgonzalesm6 That is a lovely car and what low mileage! A battery conditioner permanently connected is definitely the way to save a fortune on replacing consumer batteries.
Many people make the mistake of letting that battery run down and then trying to recharge it by driving round the block. The alternator is not designed to charge flat batteries...that is what external battery chargers are for. Mike
@@MikesMercsandothercars - Thank you.
I'm going to get a Renntech HHT(Hand-Held Tuner). It's a plug-in(diagnostic socket underneath the steering column) and play. Car should be good for 400hp and 410ft lbs.
pulling that fuse no radio volume though
Thanks for comment. What problem are you trying to fix? Mike
@@MikesMercsandothercars hi.
the dreaded battery drain ive pulled alarm fuse taken out the siren other fuses etc
Hi sorry to read you are having battery drain problems. Several battery drain issues are not fused. Let me know if you have:
1. Checked the that the glove box light is going out when glove box is closed.
2. Whether you have a phone charging cradle in the centre console.
3. Have any additional blue tooth devices been added?
4. Anything not working as it should - eg seat heaters etc
In my limited experience, a fast way to find a parasitic draw is to fully charge the consumer battery, leave the car over night and pont a thermal imaging camera at various modules and areas of the car. You can get relatively inexpensive ones that plug straight into a smart phone....maybe treat yourself this Christmas?
The first thing to check might be that your consumer battery actually holds charge. Charge it up to 12.7v (out of the car), leave it for a few hours and see if the voltage has dropped. Remember that 12.2V is 50% discharged and 11.8 is fully discharged.
Where are you based?
Mike

Less talking and looking at your friends 'Flir', turn 14 minute video in to a 7 minute video.
Yes you are quite right - I did a subsequent video….just 8 minutes:

SCRAP IT......THESE OLD CARS FULL OF ELECTRICAL BULLSHIT ITEMS ARE BEST SCRAPPED AT 10 YRS OLD!!! GET A PROPER OLDER MERC !!!!
I guess your not a fan of the SL55 then? I have lots of old mercs and I love em. Mike
@@MikesMercsandothercars Nope....this gen of Merc are all the same old crap! I had an E220 cdi...its engine blew despite having so much love and care from day 1 ....and a CL failed on me as well. Be honest they are full of shitty gadgets that you do not really need....full of this to justify a high price when new....they are not quality vehicles anymore. I have a lot of old Mercs too...R109, w202...which rust aside are way better than idiots think....drive so well ...better than the 2003 onwards crap. OK I am done. Look after your old Mercs! they are real Mercs!
