Has occurred 5 times since I picked up the car in February. At the 1000km service the dealer said next time it happens drive the car straight to the service centre and leave the engine running. Service is only open Monday to Friday 8AM to 5pm, and the problem has not occurred since at a convienent time when I dont have to be at work.

I have 2 weeks holidays at the moment and am hoping it occurs when I can drive it to the dealer. Bob

Just take it to them, and say FIX IT. The fault should be recorded in the ECU anyways.

I take your point about taking it in and having them fix the issue, but it is not that easy as the problem rarely occurs (3 times in 5500k for me). Apparently no info is stored about the problem in the ECU. I can believe this as no ECU or engine malfunction lights come on when the problem occurs. I have heard that some ECUs in some makes of cars won't let you over-rev an engine when not moving. For example, the ECU in a Falcon X6 belonging to a friend will not rev over 3000rpm unless the transmission is operating. I checked this out on the i30 and engine revs over 3000rpm without an issueso that discounts some sort of limiter coming into play. As I find new infoout I shall post further reports. I am hoping others with issues will do likewise. Bob

Bob [right][snapback]152309[/snapback][/right] Hi Bob & Tony, Sorry you two have had this issue, with Diesels they operate from fuel being injected into the combustion chamber to be ignited by compression, the more fuel that is feed in the more HP & TQ they make and the faster they go, they do not use a butterfly to control the amount of air into the motor to control engine speed like a petrol motor uses. this is why you get a slight throttle lag with a diesel, so this problem is a fuel delivery problem. i don't think driving straight to the deler as it happens is going to work if it only happens once in a while. what i think is they probably should change the ECU for a new unit and then see if it happens again. But asa i said it is just what i think, does not mean i'm right, just useing common sense here. John

I have been thinking along similar lines. Dealer says that Hyundai are looking more at the sensors and valves that control the fuel delivery rather than the ECU itself. My thought is that eventually they will need to begin the process of elimination. The main reason I will take my i30 if I am within cooee of the dealer when the problem occurs is to enable the deaer to directly put pressure on Hyundai to do something about it. I've already emailed them the link to the Youtube video. Strange as it may seem, I am not anxious about the problem, just slightly annoyed. Bob

However, the problem is not registering in the ECU. If it were, then the techs would be looking there for the problem and therefore the solution. You mentioned the ESP. I also thought of that very early on. The ESP can be turned off and I went straight to that to see if it had an effect, but it did not alter the situation. I stress again, the problem can not be duplicated (3 times for me in over 5000k over 5 weeks). When I think, hey, I did this and it occured, then I try duplicating the situation but the problem does not occur. Strange, but interesting. Bob

Bob with true data logging the system logs the data and you can play it back as it happened, you would be able to see what happened to the fuel curve. there are data loggers you can hook up and program to log all the info so you can play back on a pc later. i have one myself but have not used it with a diesel. i'm sure they will find problem if you keep at them.

It pulls ok to that rev level and continues to have good fuel economy. It can be overcome by stwitching off the ignitionand restarting the vehicle. A data logger would need to be connected for weeks to log the problem. It was just under 5 weeks between the 2nd occurence and the 3rd. That would be just over 4000k of travel between the 2 events. And as I said, no error light has appeared on the dash coming from the ECU at any stage. If a data logger records ECU events, would it record this particular event? Bob

Started driving the revs topped out in 1st 2nd and 3rd at 2900RPM. Still felt like the power up to this rev limit was good, but I do think the power was slightly less than normal. Restarted and problem was gone.

Switch it off, it resets itself and away it goes. Hasn't happened to me again. Well, I should say it hasn't happened to OURI30, although I never rev out these days. What I need is a variable vein turbo boosting my direct injection. Can I say that on here without being sensored? Bob This post has been edited by tjaliwalpa: Apr 16 2008, 02:46 AM

I have looked at them as an option further down the track. I would want the issue sorted before venturing down that path. Bob
