Hi Guys, I am having a little issue with my idle still. I have replaced my O2 sensor, cleaned and resoldered my AFM, Cleaned my ACC Valve and reset my ECU.

The problem is that it idles at 1500-2000rpm for about 5secs and then drops down to normal!

Resetting the ECU has fixed the problem before but it came back the other day after a big drive (400KM).

I am happy to reset it again, but I am guessing it will continue to occur and due to it fixing itself after a reset it should be electrical and I think it would be worth checking the ECU for error codes and might be able to narrow it down.

I have had a look but I have not found anything conclusive.

Can someone instruct me how to check for codes (is it a light that flashes a certain number of times and that number corresponds with a particular fault?) and could someone post up a list of the codes and their meanings? Any other help would be great!!

I have also read about a consult cable that connects to your notebook... This could be good, would this be a better option?

If I am able to get all the info it could be an idea to add it to the FAQ sticky.

Thanks guys!!

Todd

There will be a tutorial somewhere, otherwise any number of previous threads on how to recall the error codes from the ECU. Note however that any errors are retained for 50 "start cycles", so an error showing up is not necessarily related to your immediate problem.

To your immediate problem - how often does it do this "fast idle" cycle thing? Frankly, still sounds like a problem with the AAC valve - it needs to be stripped right down and thoroughly de-carboned.

The problem happens ALL the time. Not just when cold or first starting.

I can drive solid for an hour and stop at the lights and it will idle at 1500-2000rpm.

This is most anoying when in traffic and you are bumping along at low revs but every time you put your foot on the clutch it jumps up.

    • Plan on the day will be to park trackside. Depending on space availability we will try put a small shade tent and a few of the cars on top of the hill inside turn 3, this is an easy to get to parking area with views of Turn 2, Turn 3, Turn 4 and Turn 5 and limited other pieces of the view around the track. IMPORTANT NOTE! One consideration from previous years is from memory the trackside parking sells out before the admission tickets, for that reason I encourage anyone planning on coming to buy tickets for parking now via the official website; https://www.worldtimeattack.com/ The type of parking you are looking for is 2 Day Park & View (Access Around Venue) Vehicle Pass Only Please note this does not include admission to the event itself, remember to grab that also, and kids under 12 get in for free!

    • Good time for a carbon roof  
    • Not in any way aroused by any of those, except maybe the big AMGs. And that would break my never a Euro, ever, rule.
    • You got any more detailed photos of the tow ball set up?
