May be a pressure wash during the 1st service affected the ECM?

Anyways, good to know that the problem is traced!

That's a great news!

How ECM's fault made it to the transmission not working properly? Did Hyundai talk anything about this?

Well, I didn't have to ask them. ECM is the brain of any car these days. They control everything. If that unit goes out of whack, it will send wrong signals to the car's control system.

An automobile drive-train is a big control system, the driver is part of that system. Earlier, the cars had mechanical control systems, now they are computer controlled for higher degree of control.

Read more about ECM: Engine control unit - Wikipedia, the free encyclopedia

Even the AT is controlled by something called TCU, which is often part of the ECU: http://en.wikipedia.org/wiki/Transmission_control_unit

The strange behavior of the car lead all the experts who worked on this car to suspect the ECM from the beginning. Mechanical problem won't be so strange. Finally, they turned to be right in their suspicion.

Glad to know that the culprit was found and your car is being repaired.

Don't you think that you are lucky that you did not meet with an accident because of this?

Glad to know that the problem has been found.
I've had my share of problem with the key programming/immobilizer, read details here (Ford Figo diesel - 6 months Ownership experience).
When the ECU needs to be replaced, the keys will be reprogrammed to the new code that the new ECU expects. No change in the lock assembly is needed. Essentially, all the keys are the same, just the programming differs.

Even If the problem is fixed, I would still make an effort to check with them as to what was the exact problem with the ECU, and what probably might have caused it. I'm just not satisfied with 'replace it and it works' solutions. More so since it is just a 2 month old car, it deserves a minimum level of RCA.

There is a reason why driver is part of the control system, driver can compensate in most cases if things go wrong. And no, I don't think the problem I had would have caused an accident.

One more thing. In the two months of driving, I had noticed one thing. When I brake suddenly, I used to have distinct feeling that the car was fighting me back, the feeling one gets while toe-heeling. It used to stop half a second later than I wished. I have mentioned it here. I had attributed it to spongy brakes at first, later I wasn't so sure.

Why would the ECM fail after the service? That's the interesting question.

Can anyone confirm where the ECU is located in the i10. Also if the AT has a separate TCU where is that located or is the TCU a part of the ECU hence different for the AT.

It could be possible that the pressure wash has messed up the ECU/TCU.

That can safely be attributed to the tyres. I just upgraded to 175/70 R13 A-drives and now the braking is much much improved !

I have 175/70 R13 Bridgestone Turanza ER-60 from day one. No, it is not the tyres. Tyre doesn't fight back with toe-heeling kind of feeling.

Glad that the problem was found and is being corrected!
I will need to keep a close watch on my wife's i10 AT now for any signs of trouble.

What make is the ECU / ECM? Also, if the ECM gets corrupted won't the Diagnostic tool detect it?

What experts?

At this rate Hyundai will go the mobile phones way, installing a detector in their ECMs to tell if water contamination has occurred - and if the detector changes colour, you as the customer need to pay for the ECM because you took the car swimming in the sea!

Indeed, it ought to.

My car was serviced at Autoland, and they didn't have people too familiar with AT. Therefore, they got an AT specialist from Advaith Mangalore, which is 60kms away. He came, spent whole day and found nothing. Next day he drove the car to Mangalore. Since he suspected ECM, he ordered the spare kit from Bangalore for testing it. I figured he must be an expert since he methodically went about it and identified the problem.

I hope you are not expecting me to answer that.
