E51 High revs on idle

#41
Mine currently idles at 1100. Ive ordered a obd (last one went missing on my wifes car when in for mot) ordered the one off here as others seem to have had success with it and i know they can be hit and miss.
I will try it and the app and report back.

Worked great for me. in the app it said it had failed but within a few seconds the revs slowly dropped and now normal

Thanks to this forum for helping me solve this “issue” with our 03 E51. Had a constant idle around 1500 revs and needless to say our MPG was BAD even by Elgrand standards. Would also “surge” on occasions. I used the following info below and it worked like a charm.

Accelerator Pedal Release Position Learning

Operation Procedure

1. Make sure that the accelerator pedal is fully released.
2. Turn ignition switch “ON” and wait at least 2 seconds.
3. Turn ignition switch “OFF” wait at least 10 seconds.
4. Turn ignition switch “ON” and wait at least 2 seconds.
5. Turn ignition switch “OFF” wait at least 10 seconds.

Throttle Valve Closed Position Learning

Operation Procedures

1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch is “ON”.
3. Turn ignition switch is “OFF” wait at least 10 seconds.
Make sure that the throttle valve moves during above 10 seconds by confirming the operating sound.

Idle Air Volume Learning (Throttle Position Learning)

It is better to count the time accurately with a clock.

Operation Procedures

1. Perform “Accelerator Pedal Released Position Learning”.
2. Perform “Throttle Valve Closed Position Learning”.
3. Start engine and warm it up to normal operating temperature.
4. Turn ignition switch “OFF” and wait at least 10 seconds.
5. Conform that accelerator pedal is fully released, turn ignition switch “ON” and wait 3 seconds.
6. Repeat the following (steps 7a, 7b) procedures quickly five times within 5 seconds.
7a. Fully depress the accelerator pedal (HARD)
7b. Fully release the accelerator pedal.
8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the Check Engine Light (CEL) stops blinking and turned ON.
9. Fully release the accelerator pedal within 3 seconds after the CEL is ON.
10. Start engine and let it idle.
11. Wait 20 seconds.
12. Rev up the engine two or three times and make sure the idle speed and ignition timing are within the specifications.

I still cant get it.

Brendan, it did take me 2-3 times of trying to get it to work. I think that the timing is very specific or it doesn't work. Van has been an absolute joy to drive SINCE getting the throttle position relearned!!
ATM I am quite happy with mine ticking over nicely at 900-1000 RPM once warmed up. Maybe one day I will bump in to Mr Rob who can conduct the pedal dance for me and get her down to 700 rpm as the sticker under my bonnet says.

Mine ticks over at the expected 700-750, the thing I've noticed is when put into drive the revs don't seem to rise like other auto's I've had, the affect of this is that if sitting on a hill and you take your foot off the brake to go the van has a tendency to roll back (I can left foot brake and raise the revs slightly to get it to hold but the misses has more of a problem). Is this normal?

No matter what revs its at it should still hold on a slight hill but seeing as its around 2 tonnes anyway I would expect maybe a tad roll back. Most modern cars now have hill assist fitted on auto's like my other cars do and it does hold albeit makes safe and perfect sense to always cover your foot brake anyway just in case so I would not worry too much about it. As for your missus and as with mine too they will always have a problem:p:p:p:p:p:p:p

Hill assist comes on manuals too buddy :) pretty good. Most other auto's I've had have always held as the revs lift slightly to say 950 when you go into drive or reverse, the elgrand doesn't seem to do that the same, don't get any fault codes etc so I'm surmising it's normal. I did get the comment from the misses after around a week of owning it that I'll need to check the gearbox as she doesn't think it's changing gears properly as she never sees the revs dropping lol, had to explain to her its a CVT box and they don't work the same as a normal auto lol.

I have not driven or owned a manual car for over 20 years matey due to injuries sustained in service life so would have no idea about hill assist on a manual gearbox car.:grinning: but cheers for confirmation.

I have suggestion to high revs on idle, well on initial start up.
Older cars used to have chokes and my suggestion is that on start up more fuel is fed to warm up the car and get to operating temp quicker (auto-choke).
This would also explain why in jap 4 cats were needed to deal with emissions on cold start.
