#1: Maximum 50 code-clears for ECU Author: kernel, Location: EarthPosted: Mon Nov 26, 2012 7:58 am ---- Hi
I've read in some places that when you get a code through diagnostics machine, you can only erase these codes 50 times.
If you do more than this, ECU dies! Is that true?
I also read it depends on the ECU, but not sure which ones are affected or not.
Regards

(that you can't clear the codes after 50, sorry didn't read the ECU dies bit....) Last edited by VorTechS on Mon Nov 26, 2012 8:52 am; edited 1 time in total

it only means you will never be able to clear the code again

#6: Re: Maximum 50 code-clears for ECU Author: LeeThr, Location: North West WalesPosted: Mon Nov 26, 2012 12:44 pm ---- Only thing that can be done is to reflash the ECU so the ROM is cleared.
#7: Re: Maximum 50 code-clears for ECU Author: DeeTurbo, Location: BedfordshirePosted: Mon Nov 26, 2012 1:02 pm ---- Now, I know the ECU won't die but is the rest true, can you only clear codes fifty times?
I thought there is room for fifty stored parameters of occurred errors but surely you should still be able to clear a code as many times as you like?
The reason why I'm so interested in this is because my memory on my ECU has reached its maximum 50 and I get a "communication error" when trying to clear the fault I'm having with the MAF with PP. I first thought it just my cheap clone device playing up but after reading the above I'm worried that I won't be able to get my car sorted without getting another ECU or as said of replacing ROM. I need to give my old ELM327 ago to see if that clears the code and see what else happens with that.
I could really do with finding out about this.

Will that work?

but do you know if this is for the same code or different codes? I mean for example if I cleared the same error 40 times and another one 10 times, it counts as 50 clear-codes or just 2 clear-codes? I fear it's the first thing...

Some way to count how many clear-codes have been done?

PSA Anyway I think the car can clear itself the code when some warm-ups cycles have been done. Could this avoid getting new ECU?

'History' in PP2000 has 50 slots. Once it says 'the history is full' that's it. No more wipey-wipey.
Each slot is for one erase opperation wether you've erased 1 code or 12 in one go.
Better to get a different 2nd hand ECU/BSI+key rather than re-flash imo.
Don't know about self-clearing and limp mode if history is full.
You might be right with a bit of luck.

thanks for that
so, what a sh*t. Do you know if this is for any 206 ECU (included gti180) ?
#12: Re: Maximum 50 code-clears for ECU Author: V9977, Location: Athens, GreecePosted: Mon Nov 26, 2012 2:01 pm ---- I think so.
Might be wrong though.
About self-clearing, I think it will depend on the code as some won't clear themselves.
Still, 50 is quite a lot in practice.

Wouldn't take that much with the idiots who just try to ignore these problems instead of getting them fixed.
#14: Re: Maximum 50 code-clears for ECU Author: Steve206, Location: UKPosted: Mon Nov 26, 2012 2:17 pm ---- I think a running fault will clear itself when sorted, but a faulty sensor will flag up an error which needs clearing in the ECU. If PP wont clear the fault, then your ELM certainly wont.
I cant really understand why there is a limit TBH.
#15: Re: Maximum 50 code-clears for ECU Author: Addaz, Location: SuffolkPosted: Mon Nov 26, 2012 2:39 pm ---- Try to understand why on the twin turbo 2.2 diesel models full throttle for more than 24 hours in total (1 minute here and there) will whack the ECU into limp/half power mode to 'conserve' the engine
