Very useful. What was the total cost of repairs for you Sir?

[@EducationPineapple]

@@hiimanshusrivastava-networ314 just do a quick check on Ebay...the costs can vary from £150 -£250

[@hiimanshusrivastava-networ314]

Aye, understood. But I would need to use a mechanic (not garage*). So how many hours in total I could be looking at? 2: are you able to please share "voltage" of diesel rail pressure valve sensor?. My mechanic says, before taking the leap I must check it first. (Mine says TOO HIGH). Ta

[@EducationPineapple]

@@hiimanshusrivastava-networ314 This is a 1 spanner job (simple) on the Haynes manual scale. Consider asking someone with reasonable competence to extract the ECU following my guide and send the item off. This should keep the cost low. 60 minutes labour is about right.

[@hiimanshusrivastava-networ314]

@@EducationPineapple Sir if you have 5 minutes to tell me the voltage drop of the part I mentioned, it would be great please. I live in a remote area, all ECU repair companies are in Scotland. ta

[@EducationPineapple]

@@hiimanshusrivastava-networ314 I'm going to have to guess the voltage drop at the ECU should be 12v. This makes sense due to the large number of components in an ECU.

I have the same car from 2007. It won’t crank over and only start when you push start it. When I run the car it locks at 1500rpm. What could be the problem?

[@EducationPineapple]

Computer from water dsmage is likely

[@mgirano5822]

Thank you from France, I got the same problem with my 2010 diesel Corsa D.

[@alexprice6155]

Z17DTR?

[@mgirano5822]

Hello Alex my engine is the Z13DTR but I think the ECU is at the same place in the swimming pool.

[@Vern0191]

I’ve got the same problem I suspect. The car was actually running but wouldn’t rev past 1500 then after half hour or so the car cut out and won’t even attempt to crank over I’ve taken the ecu out and the board was covered in grey sludge I’ve cleaned it with alcohol and looks a lot better just waiting to dry off and I’m going to have to clean the case up as it’s quite badly corroded and see if that has helped

[@kuningas7]

Too bad this video didn't show the actual ECU removal process. Have unscrewed the ECU and found some manual on the net that says "Unclip front wiring harness (2) Detach engine control unit bracket from engine control unit". Having trouble unclipping the wiring harness and it seems it's keeping the whole assembly in place. :/ Can anybody help?

[@johnyoung1820]

Did you clean out the leafs etc, and clear the scuttle drain.??????? If not you going to have same problem repeating soon.

[@EducationPineapple]

Yes cleaning up the leaves is very important. Watch my follow on video where I show the viewers where the three drain holes are located, to be unblocked as a part of general cleaning.

[@gntdriver2840]

I mounted my new ecu about 1 centimetre higher than normal using nuts as spacers between the ecu and body and I also cut some drainage slots in the bodywork underneath where the ecu sits,so really there should be no reason for it to get immersed in water again.....hopefully

[@trishapnk]

Thanks a lot for your videos, they are really very useful. I would like to ask you a question, my ECU (the same of this video) is irreparably damaged, I would like to buy a reset used one, do I have to bring my car to Opel if I cannot recover the data from mine?

[@EducationPineapple]

speak to someone from the company I mentioned in the video, they might be able to help with recovering data from ECUs.

[@owain6564]

Do you have any advice for further waterproofing this component? I appreciate a breather point is needed to prevent condensation build up in the ECU itself, but could the ECU not be encased in its mount in a loose fitting plastic membrane? This would divert any water which could potentially fall straight onto the unit away to the scuttle panel drains. Is there anything you would be cautious about in doing something like this? I would ensure there was still a free flowing space under the ecu mount to prevent any pooling of water. The reason I'm asking is because I recently replaced an ECU, and had all scuttle panel drains cleared - only for my replacement ECU to become more flooded than the last one.. and I can't work out why! I've even poured a 1.5l bottle of water directly into the scuttle, and it all drains perfectly with no pooling. I was thinking of an acrylic book cover laid over the top of the unit, and wrapped under the edges. Maybe fixed with cable ties. I would have to cut holes for the mounting points but I could fill the threads with grease or something water resistant. Owain

[@EducationPineapple]

Underseal it, or heavy duty lacquer and leave essentials unpainted.

[@kuningas7]

What is the metallic fixture located above the ECU that needs removal (not shown in this video)?

[@EducationPineapple]

That's the cold air intake.

Hola, ¿Me puedes ayudar?

[@despoinavarypati7660]

I have a Corsa D 1,4 petrol edition. Does it have the same danger,cause I've been told that this is a problem that only diesels have because they have the ecu in different place.

[@EducationPineapple]

That's a good question. Open up the bonnet (hood) and look for thick electrical cables disappearing into the area I worked on where the ECU is located on mine. If there's no cable, then I guess not.

[@despoinavarypati7660]

It's at the back of the engine by your inlet manifold on the 1.4 only a problem on the diesel corsa

Hi. I have a corsa utility bakkie 2007 model. Starts up perfectly, but when driving it cuts off the engine, revv counter and speedo goes crazy, cluster lights come on and sometimes when i push my clutch in the bakkie revvs up on it's own. After the engine dies, it just starts up again easily with the swing of the key, but the starts doing the same thing again... Please help. Plugged in a diagnostic machine, no errors. Checked relays and numerous of things on the engine. No luck. All of this started after i repaired a blown head gasket.

[@EducationPineapple]

I remember when I blew an exhaust on a Ford Mondeo. The car forgot its fuel injector ID codes (see one of my videos). Luckily I had wrote it all down using a bi-dirctional scan tool and reinstalled the codes. You'll need to read off the injectors themselves. Try also checking the ECU for water damage. Open it up and look for moisture around ECU, if so follow my instructions in this video. Good luck.

[@cdc0748]

Thanks for your video. Just had the same problem on Z13DTH engine but i can’t find another ECU that has the same Serial number(55 56 34 98), must it be the same?

[@EducationPineapple]

Call the company shown in the video

[@jenj6784]

Mine has the same problem, how much am i looking at to get it repaired please?

[@EducationPineapple]

Click on my link to the company I used...BBA-Reman to see how much the unit costs. Replacing it is very simple, so I would definitely do this task myself, but ensure you raise the computer off the water line like what I did and clear out any debris and drainage holes. Good luck!

Make sure to keep your ECU above the water, plus clear any drainage. The one I fixed is still going.
