Lightbulb Ignition Coil do it yourself repair

Hi

I did not find any guide to repair your ignition coil packs yourself

so here it is

IMPORTANT ! if you buy new coils for your coil-pack, buy MOTORKING ONLY
these are superior build, supposed never have to be replaced again

ALSO, YOU MUST HAVE MERCEDES XENTRY DAS to see what coils fail !


PART 1
======================

Opening the sealed cover

First of all, I am pretty sure that the best method is to heat up the whole coil at 100 degrees celcius / 212 farenheit in a oven (this is how you remove the glass from your headlights)

I don't have a big oven like that so:


So here is my method for now

with heatgun, heat up the borders for around 20cm, then cut the whole border of
do this 20cm by 20cm

once that done all around, heat up again and cut the silicone all around



the the difficult part, the silicone around the plug

3 of the 4 sides around the silicone plug are easy, space enough to insert a hot screwdriver and push the silicone

one side is impossible to insert a screwdriver

solution is to drill a small hole on one side to be able to insert the screwdriver





result












PART 2
======================


THE FAMOUS OIL IN COIL LEAK




So, when removing your coil pack you will probably find oil in the last, passenger & driver side coil.
Why ? it's just the two cylinder head gaskets
change them !, preventive too ! because these leaks can kill your coilpacks
A1370160221
A1370160321




Rubber gasket had no breaks, but was hard cooked





PART 2bis
======================

sometimes your problem is just these sensors, not your pack


also, if you have one side failing only, swap the camshaft position sensors left with right
and see if your problem changed
if not, they are OK
verify they gaskets and clean them up













PART 3
============================

sometimes your problem is just these spark plugs, not your pack


before testing, if you don't know how old they are or they have mileage or look old
replace all your spark plugs !
THE ONLY RECOMMENDED PLUGS ARE:

NGK 5648 / IFR6Q-G

laser iridium






PART 4
==============================

sometimes your problem is just this transformer , not your pack


Problem could also be your transformer
easy to open don't worry

verify the device like here



PART 5
====================
sometimes your problem is just these spark insulator caps, not your pack


If you go for a repair with old coilpacks
you might want to reuse the old red spark insulator caps

I went for a superior upgrade

24 x BERU GS30


OEM part is
A0001590080





PART 6
====
===============

The mosfets replacement, don't forget to use thermal compound and cover the with epoxy once finished




sorry, green dots a bit small but just download the picture and zoom in

only GREEN and RED mosfets are provided in repair kits. maybe because those fail most of the time

additional info, it's confirmed, the UR4120 mostly NEVER fail. so you probably never need to replace these.


Products you need for mosfet replacement :





MOSFETS DATASHEETS:

for this adventure, I just got 2 packs from same car L & R
left has 4 coils failing, right only 1
price 500$

don't forget that if 1 cylinder fails, not both coils have a problem
so I potentially have 19 working coils and two working modules for that price












If you replace cover gaskets also, why not replace you engine wiring
MB recommends to change these as the heat dries them up after 8 years
make sure you get latest model A2751501833

I found a close to new one

ebay is full of them




more tips further in this post

Interesting. I just swapped out my left side coil. I have two complete coils and the igniter I need to sell now, one has a broken coil (damaged during removal), and the other side started to develop misfires on the rear 3 cyls and had codes for a Cyl #10 A/B coil fault.

You know what ? when I feel a mystery ambiance, I always need to find out.

I have been doing some soldering over years, my experience is that I don't want to touch Iphones and ECU chips anymore

this I don't touch



this I do solder


so seriously, did you see the size of the soldering on the coils and eventually the mosfets ???
Even a blind could solder that !
So that added to the mystery created that there is nobody explaining you how to open these packs ...... weird !
only warnings like, you can fix it yourself but don't !

this is why, ladies and gentleman, I am doing it... I didn't say I will succeed, but probably

You are going to need some high-end soldering and de-soldering equipment to replace those MOSFETs without damaging the PCB. Not only that, there are numerous (very tiny) associated components, such as MOSFET driver ICs, flyback diodes, etc. around them that could also be faulty.

Good luck, you'll need it.
I have never been talking about repairing the board. If you had informed yourself you would know that the motorking repair kit comes with 2 mosfets per coil
that is preventive
and that, even a donkey can solder

So how do you know whether a coil itself is bad, or whether it is the driver circuitry? Do you have a testing strategy, or will you just shoot the parts cannon at it and hope on blind luck that you accidentally succeed?

freedom of speech

First of all, if you don't have Xentry Das, forget about it (just added that to the threat start, thx !)

I will be only switching coils and eventually those two mosfets according to DAS
if the board fails, then I can choose between a local electro repair store or discard it

Check the secondary between the spark plug spring terminal and the shell ground. Resistance should be relatively higher. Might save some money by not replacing a coil that may actually be good.
if you want to explain that on picture
here is a link to two pictures so you can download them, add comments and post it here

Anyone with electronic skills

here is a image, if you can add a resistance measurements manual, that would help
