Vauxhall/Opel Corsa D 1.3CDTi, can I fix this one? P0204 and already had injectors... 

Hello from France, Luis, If I had to describe your videos, I would say: simple, essential ... but terribly effective! Your working methods should be taught in schools! It's a pleasure for me to watch them every time you post one. My only regret is not being near you, spending time in your workshop, offering you coffee and chatting. ;)

Amazing fix, I was just thinking as you were repairing that ecu, "what if it makes the problem worse" . I'm glad it all worked out in the end. There should be a Vauxhall bulletin on this drain and ecu sealant placement issue. Great job, I love your channel

Great video Luis, I've just bought a corsa with a misfire and they've tried everything except the ECU! This will be an easy fix thanks to you👍👍👍

Great repair Luis, helping to alleviate the lockdown boredom👍🏻👍🏻👍🏻

Better technician in the world !! true true true thank you so much, always your number one Respect

Again another great video from a highly skilled Mechanic/Auto electronic expert/Auto electrician.

Well done, Luis, getting it working....braving the elements and hoping any middle layers are ok...our knight in shining solder. 8-)

Good job you are an expert we learn from you teacher.

great repair plus showing the whole procedure very interesting in this type of video,sa lot of persons only show basics well done LOUIS GREAT VIDEO

Great work Bro👍 Really your repairing techniques are outstanding, we have a lot to learn from you😉 Great content, Stay Safe❤

Top work as always in all aspects..Thank you for all the videos

We learned that when Opel Corsa has problems first open ECU and check for moisture before replacing other parts.owners should clean drains every year to keep their ECU from water damage

Again great work, learning so much from you 😁. Keep em coming

yes well done good job there, if I get one of these that will be my first check .. they could at least have attached an under bonnet sticker warning to keep the drain clear .. they must know it's a problem and one day the ECU is going to flood, so there's a problem with a drain that gets blocked and another problem with the ECU not being water tight, good combination tut tut tut.

One hopes that the "designers" that made the smart decision on where to place the ECU in this cars, do not make those on an EV, just imagine a 300V system under water. Great video as always.

hi mate, heeeep I lived in uk for 10 year end I had a lot of experience with theas corsas. thanks for a video.

I love your approach, great job

very good one as the others , as I said before you must be a wise guy to focus on the fuses on the board that were blown ... and you even wash the place where problem can reoccur , who would do that in the world other than you , amazing ...

Great job, I learn alot from you about circuit boards!

Love your accent!! Really intresting video Very helpful 👌

I have the corsa 2005 cdti and the ecu to the right of the engine which is better my issue is with my feet getting wet brake booster seal I think. Another great video 👍

Knows what he is doing. VERRY GOOD

Brilliant as always Louis

excellent work and a great fix..well done.

Great stuff. Great result. Repaired the ECU itself ! Some skill to have . Where are the actual drains that were blocked ? Would have been nice to see the signals to all of the injectors on a scope when diagnosing.

Excelent job Luís, great vídeo i enjoy it a lot. Thanks for One more.

Well done yet again.

Very good and useful! 100 tagged smd resistors are 10 * 10^0 = 10 Ohm right? So 2 of these in parallel are 5Ohm.

"Standard" problem on this Opel's , but I guess you figured it out over the years :) You have to much patience my friend , I hope you do not charge peanuts for this as this MJD ecu's become harder and harder to get.

Greate jobs ❤️❤️❤️🌷🌷 very good, every day I check your channel for new video. Thank you very much mate ❤️❤️❤️

Hello! Good job, I have an ecu which the problem is no accelerate possible (motor starts), and other ecu which ecu works fine in 90ch car not 75ch car (diagnostic says "booster pump "). Have you idea root cause please? Thank you.

Great repair mate 👍👍👍

You did that perfect . I have seen a fair share of rain damaged ECU´s but I don´t go as far as you . EEPROM , yes . Maybe a mos , but that´s it . You seem to be catching up on the uploads also ( haha ) Soon it will be again 1,5 - 0.5 degrees .

Can you make video on Saab 9-3 with B207 engine ECU? It’s the greatest automotive industry phenomenon. Noone understands why and what’s failing and it will send most of the cars to scrap soon apparently. The „fix” is almost 500$ and means replacing it with used one that can also break anytime. Solution is so badly needed...

Hi , I have a Corsa 1.3 cdti it intermittently won't start and also won't rev intermittently. How much would you charge me to repair the ECU if possible ?

seems a common problem on this car model. a brilliant idea to put the ecu near a bulkhead that could clog submerging it, and then they call themselves "engineers" at opel .. As always, good job Louis

Very good video , I'm subscribing

Great work as always! I have the exact same ecu with the 2 ceramic capacitor's that are completely destroyed. By any chance do you know the value or what replacement I will need by anychance? Any help appreciated. Thank you!

Thanks, Luis Great job,

Great video,has helped me loads, 1 question, what type of sealant did you use? I’ve opened my ecu because moisture was getting inside and cleaned all old sealant off,just hoping you have some tips for me please. Regards Simon

You are one clever geezer !

Nice work thanks for repair.

Nice repair video

Perfect repair 👍👍👍👍

Good Job. Love it.

Hi, which one is the earth screw for the ECU?

Very well done . Bet you're bored of these ecus now

Thanks again for another just great video!! It surely beats watching Hollyweed movies. I think that NO engineer would do shite like that...to put the ECU in that place of *future* water accumulation!! No,that is the Management job..planned obsolescence, by them smart asses,while the GOVs look the other way. edit::::::man,you did the right thing,leaving that rubber plug out||||; if the car was mine i would drill 2 holes, 1.5 inches in diameter right under the ECU,with a hole saw,and protect the edges with a little paint; no way water would ever accumulate there again.

hi my friend has a combo van 54 plate it wont rev over 3200 rpm he had the car scanned which said egr valve that has now been replaced the code has been cleared and it hasn't come back but it still wont rev over 3200 rpm could this be an ecu problem thanks

Great job 👍👍

Hi.. I have a 2013 Corsa D 1.3 CDTi Limited Edition, I only bought the car a few days ago and the car was running ok for about a day or 2 then it started to lose power, the EML light and Car/Spanner light both came on. The car ran like a bag of spanners.. I limped it home and plugged it in to my Maxisys 906 and it threw up so many codes i didnt know where to begin I removed all the codes thinking they could be historic codes, they all cleared but upon doing a fresh scan they were all there again.. The EML and Car/Spanner light are intermittent but i daren't drive it just in case more damage is caused... I have now removed the ECU and in all honesty it doesn't look like it's had any water ingress although the drainage holes were all blocked up with leaves, it was also slightly damp around the area but no puddles of water. Any advice would be greatly appreciated.... Great videos.. very informative .. Top Job !!!

Good job dude

You caught that one in time. You have to wonder why these big companies make such a rookie mistake like putting the ecu there! I had a similar issue with my sisters washing machine and had to do some remedial pcb repair work. Again bad design not protecting electronic from water.

This is why I always remove any leafs evertime I see them

Whell i was having the not starting problem so i was sendig the ECU to a compmay that can fix the ecu. Know the cars starts up but got a fault Kode egr tempartur sensor i and my antisspin is on. 😔

Didn't know you are a Trance lover.

hello what do you diagnose you used to have Autel MS 908S right? Greetings from Poland ;-)

Hello i have the same issue p0204 and the car go to safe mode is 100% my ecu need fix? Is possible for bad fuse or. My injection prpblem?.. And i have replace battery 1week ago. I have fix my ecu 1 year ago..

Well done.

I got same problem it’s says injection 4 open circuit i took my ecu off the pad as come of the compositor can I just solider new pad on and replace compositor

Nice work and repair again! I have replaced a ECU to a new one on a Opel Corsa 1.3 CDTI Z13DTH, where i suspect i got a broken ESU. There are no fault codes in opcom or any thing and the car will not start. I have tried a other obd tester where is says: "fuel system monitor bank 1" - manufacturer defined test FAILED (value: 0, should be 0.6-1.350) - The new ECUs PCB looks new and not damaged. Do you have any idea what this is?

Great job. Your videos are excellent, thank you. I noticed you have an interesting linguistic construct where you say, “Let’s gonna ...” and I’m curious where that originates as I have an interest in the subject. Is it from another language or maybe an abbreviation of that odd American “go ahead and” expression?

Well done!

Hello . I have a problem with exactly the same ecu for the opel corsa d 1.3 cdti. I have this error injector no. 1 does not work P 0201 I cleaned but in vain .. please a piece of advice what should I change? Thanks

Also I have a Vauxhall Combo 13CDTI, 2008 plate , she starts no problem , runs ok , but when I get into high revs in 3rd gear she holds back, then I change to 4th gear & she splutters, no power , I have to dip the clutch and give it a few revs then it's ok again, but this is starting to be everyday now

I have a faulty ecu capacitor 1 high voltage can you help me

Hi nice work

where did you get them nice fine probes for you meter

Great work👍, I am trying to repair water damage, have damaged smd ceramic capacitor, the same one that you had to move to the side of the track a 1608, I think, but I don’t know what value it is , corsa d ecu video 2020, would be fantastic if you can tell me. Stay safe.

Hello. Where did you get a circuit board diagram? Trying to find it in Opel TIS 2000 but here is something odd actually...

very good job

What led you to the resistors as the fault? Was there damage or were you just checking values and found it? Thanks for the video

What kind of kit do you use for sealing the ecu?

top video many thanks

nice work

Hi, does anyone know what a clicking sound behind odometer means in corsa d 1.4 petrol. This seems to happen and engine starts normally it continues a few seconds the goes silent the engine runs fine. My only thought is battery is becoming flat after not being driven or started very often.

thanks a lott ...you' re the best what is your scantool' s name ??

great job

U r magician! Man wooo 😀😀

I can feel a jet of air on cylinder 2 injection and it makes a hissing noise. Do I need to change the washer on the injection.

Hello, I think I may have the same problem. My corsa D was running poorly. I got a P0203-02 cylinder 3 injector 3 circuit low fault and engine warning lamp. Now today when I start the car it stops after idling for 1 minute. There is no crank. Fuse 20, main relay 10amp fuse has blown. Codes are P2146-02 capacitor voltage 1 low circuit and P1625-02 main relay output voltage low. I have replaced the 10amp fuse and it blows again when I try to start the engine. Should I change ingector no 3 or do I have an ecu water problem?

opel corsa 1.3 cdti has difficulty starting when the engine has a temperature of 90 degrees. obd2 gives no problem. has new engine injectors and pump in order. please help me.and the electric fuel pump is ok

11:03 - when it finally starts turning and you realise after it wasn't the screw :( 34:20 - Same thing used to happen on B5 Passats under the battery, most owners take out the plugs

Hi. Nice job. Can you help point me. My car not start. Fuel pump not runing. Main relay circuit high voltage.

Hiii...what is that chip above the eeprom for???? plzzz advice...thank you..its above the eeprom..

Offtopic: How do you like that Nevex solder wire? Anything special?

Any help would be appreciated. I have a corsa 1.7 cdti 2011. Over the past year it has had intermittent issue when under load it would hiccup and go into limp no codes would appear either. Couple of month ago stayed in limp and gave faults of p0088 and p0089 high pressure detected. Bought new regulator installed with no change. Replaced fuel rail pressure sensor. Now cranks but won't start swapped sensor back to original still no start. Thanks in advance

I made a fix to relocate the ecu for the the 1.3d just outside the bulk head due this flooding issue

How do you remove sealant from ecu. Do you use some chemicals?

Two resitors in paralel in circuit mesure 1/R1+R2, so you will never get to measure the value writen on top of them. You will have 1/200+200

The man

Have you bought yourself a artipad, or is it on loan again its a nice tool I would like one but cannot afford it just yet, I did buy xtool pad 3 as well as owning a texa diagnostic tool.i like my texa but like when you look at a sensor you can see all the reading of that sensor I cannot with mine just get grafts

I need your help

what did u charge to do repairs

Put a clear coat on the board. Future ingress of water will not affect it.

That ECU looks like it was doing swimming lessons

Please help! I had this issue with misfiring, running on 3 then only 2 cylinders. Went through the whole injector thing no change, so went to ECU. It was indeed wet so opened it and there was slight corrosion but after cleaning with IPA seemed fine. Went to test it but now it cranks but doesn't start. I did disconnect the battery negative before unplugging ECU, also charged battery, no better. Can you help me please, I love my Corsa but my mind is on scrapping it! I'm so down right now!!!

Bravo! My mecanic is an idiot! I can show this video, THX!

Why do they have a spanner light that behaves like a engine light
