Crank Sensor relearn?

[rayray3009]

Do 3.0l E53s need to relearn the crank sensor after replacement? im asking because i swaped out the sensor this weekend and now its throwing crank sensor timing codes and transmission 'engine timing'codes it was ok before the replacement i used a Delphi part if that matters
thanks Ray

Nope, no learning involved AFAIK. Why did you replace crank sensor?

[rayray3009]

It died and wouldnt restart for a few hours two weeks ago. then it threw up a crank sensor code last week. so, i thought it was going bad

Yes matters. Use OEM only for crank/cam sensors.

I would put the other back in for now and get OEM part from FCP euro or equivalent.

FCP Euro has the Delphi listed as OEM and the VDO listed as OE. i have a VDO on the way. i cheaped out and got the Delphi because it was $15 cheaper. didnt think it would matter

OEM is ok. The Delphi should be ok but you may have gotten a DOA. Does the car start just gives error ?

[rayray3009]

yes it starts, LONG CRANK <-- thats a new thing and runs like crap and throws these errors UNDER The Trans Module 96 can engine speed under the ECM 53 signal crankshaft sensor
F4 segment timing true running disturbed mabye the Delphi is dead i didnt have these errors before the replacement

Andrew and I have had a fight about this in the past, but it's important to note that OE and OEM do not mean the same thing. Delphi is OEM because they supply some parts to BMW. VDO is OE because they supply THAT part to BMW.

A lot of the world treats OE and OEM as interchangeable, but they are absolutely not. And in particular, FCP explicitly uses my definition.

thank you so much for the OE vs OEM differance i never knew but it will help me in the future

Though I'm new to the BMW world, I have been working on cars & trucks for 57 years, learning as I went. I fix what I can with whatever I can, using whatever parts I can. Depending on the importance of the parts involved, the availability of those parts, and the cost/investment involved (in money, in my time, in difficulty to replace), I have tried components of all sorts , quality, and price, over those years.

I've got 90+% of my experience working on domestic vehicles, and the rest on Euro & Asian cars, so my components have come from all over. While I used to use only American tools & parts, now I use mostly foreign-made stuff, generally due to price & comparative value to me. And then, does anyone still know for sure the provenance of their tools & parts nowadays, anyway?

Right now, only some of my older tools are USA-made (some from the '70's), while the newer tools are made offshore (not sure about my Milwaukee tools). My tires (on five cars & trucks, and two trailers) are a mix of 3 US & 2 Japanese brands (only two were not made in China, but even if they were, they're not of low Chinesium quality). And as for the cars, they all have mixed heritage components, as manufactured.

These days, I try to get known/trusted brands of components (especially critical or hard-to-replace), if those brands have been proven reliable to me, in the past. I hope that the newer parts, even if made in China, will be made to a certain level of quality, that the old tried & true mfg. used to make.

Electronic components are the newest product category to add to the mix; the switch to offshore manufacturing plants by corporations world-wide has made buying reliable parts a crapshoot. I still mostly buy AC-Delco, Delphi, Bosch, and NGK electric and electronic parts, even though I've had some failures with them, but never buy new-to-me brands, unless I research them online first. Parts (especially electronic) for the X5 are going to be chosen by three criteria:

• 1) how critical is that part vs. price,
• 2) how hard to diagnose/replace the part, re:upcoming failure (if ever, in the future) vs. price, and
• 3) relative value of a "better" part (OE, OEM, BMW-branded) vs. a lower-cost, but seemingly made to a comparable standard by another manufacturer (preferably European or Japanese, or by one of my trusted brands).

I recently replaced a camshaft position sensor (exhaust) with a VEMO part (sub-division of Vaico, a European mfg. company). It's even stamped with GERMANY on it. Since it's easy to quickly replace, I figured I'd try a new supplier, just to find out if their quality is up to snuff. I can get a replacement overnight, if I need one, and since I always have a scantool hooked up, I should get a warning of imminent failure, beforehand. Of course, if the component is really hard to access/replace, if partial failure will instantly destroy the X5, or if no reasonable alternative to the "best" is available, then I'll defer to BMW or comparable-quality parts, always.
