-01 520i m54 inpa 83 kw error & 244 segment time measuring faulty

[Santalo]

Hello,

Car wont run 100% and i have those error codes. Asc light came on at the same time. I have replaced crankshaft, both camshaft and TB sensors, all original parts. Still same fault.

What next? Do i have to reprogram/update dme at dealer after i have replaced new parts? I tried to erase error codes with inpa, no luck.

Engine wiring harness? Faulty DME?

Can i buy used DME with same number and somehow get that working with current EWS etc?

Any help would be appreciated.

Most of us are not familiar with INPA error codes. Please try to read P-codes and report back.

Hellow, I'm desesperate! I'm having the exact same issue. I cannot use my car. Same inpa codes and same ASC light with limp mode.

Have you solved this issue? Any help would be great!

Thanks!

Just the same here in my ´00 530i...ASC light on and the same INPA engine codes, plus a ASC error code.

I was driving in the highway at about 75 mph when I noted a small hesitation and saw the ASC light. Although my car was able to mantain 75 mph perfectly, it lacked power and revved more slowly. Back at home I connected INPA and pulled this error codes. I cleared them and the car goes right now, with the ASC light off, but it happened twice this week so it´s probable it will happen again soon.

Please, any help...thanks!

Always a great idea to bump a 5yr old zombie thread with zero helpful content. That always works great. ( <<< meaning it does NOT usually work at all).

"Exact same issue" is more often than not, NOT exact same issue.

Regardless.

I'll grant you the codes are a bit cryptic in this case.

Here's the easy code to decipher: NMOT = engine RPM signal, and therefore for some reason the ASC is complaining about the engine RPM was not being available on the CAN bus. That one seems easiest to understand.

So why an RPM problem? That may be because of the other errors.

On the 244 - "KW" says "wheel sensor", so... maybe its related to a bad wheel sensor signal... but in some DME German abbreviations I know KW = crankshaft. So, that might actually be more related to crank sensor, maybe RPM signal is dropping out and then causing the other errors? The 83 then sometimes appears listed as a DME-cluster CAN signal error.

So it seems to me either wheel speed and/or engine speed are dropping out, either that or the CAN bus has a short someplace and is 'hiccuping' for a moment.

Those just my best guess.

I reused the old thread because I thought it was a good idea, having my car exactly the same error codes, instead of starting a new one. In some forums moderators suggest to reuse old threads in order to have the information better sorted, but if Bimmerforums practice is opening new threads, I´ll open it, no problem.

Anyway, thanks for your help. A few minutes ago I discovered that KW could mean "crankshaft" in INPA but that is confusing...the car runs very well, no stalling, etc. that were symptoms of bad crankshaft/cam sensors in my E36 328i.

A pair of things I didn´t say:

-When I bought the car last summer, it had a problem with the ABS/ASC module (ABS and ASC lights on, speedo not working). I installed an used module (from an european market ´99 530d) and it worked straight, no coding needed. No problems since then.
-When I arrived at home, I turned off the car and, a few seconds later, turned on the key. The engine was cranking for 3-4 seconds and finally started. I repeated the operartion, another 3-4 seconds cranking. Before this problem my car started right away, and after clearing the codes, it starts inmediately again.

I replaced the crankshaft sensor with a VDO Siemens one.
I´ve driven 2100 kilometers after that, without a single failure, INPA showing no errors. The car runs great.
