Very beautiful hybrid microelectronics board in this one !
Hi Bob!
The oil In the ECU comes from the oil contact sensor which is causing the oil warning lamp to extinguish after engine start if the oil pressure is O.K. Most modern cars have processed the information from that sensor in the ECU and then it is transferred to the dash panel. Because the the plug from the harness for that sensor is sealed connector type, when there is a leak in this sensor the oil pressure (when the engine is cold or in high revs. with warm engine it can reach 5 bars or higher) gets in the sealed connector of the ECU between the wire and it's insulation (capillary effect) and then it's possible to enter the ECU itself between the pins and molding of ECU connector. I have seen such problems even with the Engine Coolant Temperature Sensor. If signs for oil or coolant in the connectors of the ECU the above sensors should always be replaced.
Very interesting, thanks for showing, though I fear my hand would not be steady enough to work on these :)
Hi! There is only one way to learn to swim. It is jumping into the water. Try to practice with something else first. Our hands skills are the product of practicing. I am not repairing things in the last two years. Every time I try to rework, I have to star re-training my hands, because I am old and I lose that fine movements after a while too. :-P Happy new year and thanks for writing! :-)
Thanks a lot!
thanks Bob!!
You are welcome!
Muchas gracias Bob
Con gusto! :-)
Very interesting
keep up the good work
Hi,
A question before I start to dismantle my ecu. Is there any difference in type after 5WK9 number? Mine is is 5WK9 1720. Can I replace that one with any 5WK9 or this 1720 number really matters.
Thanks a lot in advance for your opinion.
Nice video. I did job, same of this. It's not so easy job. :) Just one question, collegue: how did you remove silicone insulating substance, from wires? I used alcohol with wadding sticks, but, it's not very comfortable..
Great video Bob. I have a Vauxhall Zafira 59 plate (2009) which keeps illuminating the EML (Engine Management Light) on the dashboard causing the vehicle to shudder and restrict speed. The fault had been diagnosed as Fuel Injector 1. I then had Fuel Injector 1 replaced with a brand new one and the car was fine for just over 2 weeks until the EML illuminated amber again, the fault has been diagnosed again as Fuel Injector 1, is this likely to be the ECU?
Hi! Yes, it could be the ECU. (But check wires first to ensure good connection and clean contacts). A defected injector can damage the output transistor. Or a defective output transistor can be accused as defected injector. Bad power supply connections can be reflected and error en the components that more current use in the system too. Also a broke wire problem like in the video could be possible.
Nice work bob. How did you remove the protective gel?
Hi! I used a wood matches. I spread a little the wood fibers to be able to remove it right.
Hello Bob, how did you solder the wires. And which material did you used. thanks
Hi! Wire 30 WAG & Kester rosin core solder 63/37 0.020
Hi there, is the computer box waterproof? I just cleaned my engine with water & the just cranks & its not starting
Hi Bob, this is a very good video!!! Thank you for this!
I have two questions:
1.How can I ask from the shop the glue around the ECU for sealing it after I will finish with it?
2.Which is the name of the transparent glue/material(silicon gel) with which is covered whole the surface of the circuit in case I want to replace it after I will finish?
keep up the good work!!!
Did you find the glue for the sealing? I could use this information too.
Hello, maybe you know something about fault b3059 opel astra g 2.2dti
Hi Bob.. thank you for this video....i have opel vectra c 2007 my problem is the fan for cooling not working and the indicator of temperature is not working too, can you help me in that ??
Hi Ahmed! Fist check temperature sensor, contacts, connection, and cables follow up.
Does opel agila engine ecu needs initialization or programming when you are replacing a used one?
Hi! I don't do programmings. I just worked in general electronics repairing. But many car models, will not start if the ECU had been changed. Programming is needed to associate the key.
Hi can you use a petrol ecm for diesel car
I hope you're still reading these. A friend of mine had his Zafira jacked. They stole the ECU and the thieves didn't simply disconnected it, they cut the wires. He managed to purchase a new ECU, but they didn't have wires/connectors. We're trying to find that part but we're stumped. Can you guide me where can I find that part or at least the part number so I can try and find a replacement? I'm talking about the cables/connectors that connect to the outside of the ECU from the car. Thank you in advance.
Hi! You have to find a used auto-part shop. Maybe you can order the arneses. Better option is to visit the junker or car bone yard and get the wires himself. (He will need connectors, the extra piece or wire, and some of them are connected to sensors, so to join the wires can create serial resistance with the sensors signal. It is better to replace the whole wiring).

Super video.
I would like just one answer from you couse I have problem with nobody can't solve.
After diagnostic " camshaft actual position"
I change him and variable pulley also same storey.
When it's cold car, it's going less than before when I haven't that problem.
But when car passed few KM and start to be hot the can change some MODE, GAS star to loose power so much that I can't In first gear start on some Hill.and in the same time on gasoline, start to be Lazy.

Can that be computer?
Hi! If something went wrong, "only that part" will fail. But when there is an ECU with bad wires array connection like in the video, "many things" no related with each other will fail at the same time. Most of the time bad wires ECU will fail after warming up, some minutes of driving, bad road or in some speeds because the car's vibrations.
hi Bob how did you clean silicon gel??
I remove it with the tools showed. But there is an invisible thing I add to it. "A lot of pacience". If it didn't work fine, I add perseverance and everything in the area to repair gets clean. ;-)
How do I send an ECU to You for inspection and repair please Bob?
hi I have an opel asta 2005 central locking and remote control does not work the fuse is good have everyone checked?
Hey,can i reach you to assist me with the trouble codes i have?

Hi. I have a Zafira 54 plate which has had errors 1571 (brake sensor), 1482 and 1483 (fan relay) for last 2 years. It then suddenly developed codes 1122, 1120 and 1550 and went into limp mode with no more than 1200 revs. Had new accelerator and pedal switch fitted and all codes cleared. Drove ok for 2 days but sometimes felt slightly hesitant when accelerating. Then spanner light came back with codes 1571, 1482, 1483, 1122 and 1550 (1120 no longer present) and then intermittently went back to limp mode (usually just after starting car when slightly warm) however, a simple lock and unlock of car temporarily resolved this. I have a feeling it could be the ECU. Does this sound about right? Sorry for lengthy explanation, just wanted to be clear with the fault.
Yes. One specific code is one specific problem. But a lot of codes, and some times no code is related one with the other when something went goes wrong, means bad connections in the ECU. Your problem's description match the problem fixed in the ECU from the video.
Bob. Kalpon Thanks Bob
Hi bob can I send you mine for repair what’s the cost please 👌
Hi my car starts and when i accelerate it just cuts out any ideas?
Is it a defective MAF?
Hi, do you still repair these ecu's
Hi! No. I did it as surviving some years ago. But I am not in the repairing business since 2017.
Guten Morgen .. Nach ADNC ich ein Problem in Ecu in meinem Auto Opel Zvera 2001 habe ich kaufte sie von einem Auto Ecu Opel Astra Modell 2002 und arbeitet immer noch nicht mit der Wissenschaft Autos den gleichen Motor Z18XE mögliche Hilfe
Hallo! Hast du es gescannt? Gibt es einen Code? ... oder ist es tot tot? (Ist die ECU mit dem Schlüssel des tatsächlichen Autos programmiert? Was sind die Symptome?)
hi bob my 2010 zafira petrol has stopped working, no ignition, no start, dead, a can bus code has come up, any suggestions please?
Hi! If all looks like dead, then check the main fuses. (Also check for old alarms installed. It has a cut off circuit. A friend of mine had the same problem, and it was an old alarm circuit installed).
@@bob.kalpon1398 there is no alarm fitted, but which are main fuses, i have a feeling it might be the cim unit as i recently had the horn repaired.
@@trabali5168 Mmmm..! Your electrician was in the main fuse, where the horn is, and also he touched the steering wheel. High chances are you have a lose contact in the main fuses or under the steering wheel key connector, and it justifies the power insulation.
@@bob.kalpon1398 i will try the fuses..do you have an email if possible
I have 2007 Opel Corsa 1.2 with ECU problem. My ECU part number is 0261208940. I can't find another used ECU with same part number. But I found 2008 Corsa 1.2 ECU with part number 0261208253. Last three digits are different. Would it fit my car?
Dear friend, I will kill you with my ignorance. I am electronics engineer. A mechanic or autotronics technician in Opel has the right answer for you. Yes, there is a difference. It is not only for the year, but for the extras in the system. Most of the time, the newest model can control the oldest one. Also, some extras are ignored if they are missing. I am "new in Europe", and am trying to learn it too. I saw Opel Corsa looks the same from 2007 to 2010. But I have not formal information to tell you. Maybe in Opel Clubs online, used part's shop, or an Ebay ECU supplier has the answer. And as I said, an opel mechanic is the best source for your answer.
Жаль что не русски всё рассказывает, у меня точно такой же блок и беда случилась с иммобилайзером.

But penetrating oil will help the electrons flow through the ECU haha

donde estas puedo enviar o llevarte mi ecu????
estoy en la cd mex
Faby, Faby..! "Toy del otro lado del charco" y eso es muy lejos no solo en distancia, si no en envíos e impuestos de importación y exportación. El mejor consejo que te puedo dar es con el número de ECU, busques otra en MEX o en Internet en Ebay.
Opel, vauxhall/gm cars' ecu problems are common issues because of corrosion due to water damage. Bad design that these ecu are located where water is always present or draining. Also, no added plastic protection cover against the elements. Car has plenty of room inside the cabin that these delicate electronic parts should have been located. I own a vauxhall car now but will not buy any of these again.
Yes, just using common sense, inertia forces applies less in the chamber than in the extreme . Adding to it the lacking of plastics or rubbers, we ended applying movement to those wires inside the ECU. We only need one collision in the car´s history and we can add a ECU wires failure to the list of damages. It is good car, but if we buy Opel, we must think about to change tires, filters, oil and ECU too! ...why not? :-))
These cars would be good if the electrics weren't a fail.
Couldn’t watch video to many adds
