Borrow someone's Peake Reader for E39 M5 and if you get the right reading on your friends Peake Reader, then time to return your Peake Reader back to where you purchased it from.

I think you are in New York or DC area but If you live here in Seattle area, you can borrow mine anytime.
Thanks for the advice. I've actually had a thread up for the last 2 months trying to borrow a Peake reader locally but nobody's volunteered...I'll keep trying and I'll contact Peake.com

Ted, stupid question but I just have to ask - you have the key in the 2nd position right? I don't think it works at all in the 1st position but maybe if it half works it gives the wrong codes.

2nd bonus question - have you had the OBDII TSB done?

[quote=whatheheck;1095554]I find my Peake Code Reader manual very difficult to understand. For a simple person like me, I like simple & easy instructions.

So I wrote this below on a word document, printed it and attached it to the pouch of my Peake Reader Tool.

Let me know if I have made an error or my understanding of pulling codes and which table applies for our E39 beasts is incorrect.

Peake Code Reader instructions:


Note: The reader defaults to FC (Fault Code read mode). For pulling fault codes follow simple steps below.

For E39 – the only applicable table to use is Table 18. No need to look at the other tables.



Is the above statement true that ONLY table 18 is needed for an E39?? I don't think so. I have an M5 and a 540i. I just got codes OF, 50, & 51 on my 540i and table 18 makes no sense, but table OF yields secondary air system which I believe because both times car was stone cold and backing UP the driveway as it had fairly deep snow. Where does this statement above about table 18 come from. It's not in my Peake manual??

BMWx2 - The statement should be that Table 18 is used by the M5 ONLY. AFAIK E39's in general use additional tables.

I can't for the life of me remember where I learned this, but I don't think it was the owners manual. I seem to recall that because the M5 was the only vehicle with the S62 engine it ended up with its own set of codes.

SES light - error code interpretation sought

Hi all, I have a 2000 e39 M5 (production 11/99) with approx 63k miles.

Last week, I was driving when my SES light lit up. I just hooked up my peake reader and the following codes appeared:

table: 1b
code: AA
code: 50
code: b2

My manual states:
AA= secondary air system - flow too low
50= switch chain grip
b2= catalyst system efficiency cyl# 1-3

I have owned my beast for 5 months now purchased it with 57k miles, and the only problem I've had was my clutch @ 62k miles. It has upgraded CAI from aFe, that were on when I purchased in August. I am not sure how old they are.

I have not noticed any degradation in performance, over the past few weeks.

My mpg is approx 13 around town and 16 on the freeway, but I have attributed that to my inexperience at driving a manual. This is my 1st BMW, and 1st manual in many years.

Can anyone help me interpret the codes? I have seen some explanations for the AA, but have not seen the 50, or b2.

This board is awesome, and any help is greatly appreciated!

Thanks...

I must admit, I have no idea what code 50 is, obviously a switch gone bad somewhere, but on a chain grip?? Sorry

b2 is pointing toward one of your cats - but it could be something to do with the O2 (Lambda) sensors.

Those sensors are very easy to replace and are not very expensive - that might help with one of your codes.

Maybe someone else will reply on code 50...

best of luck,

Richie.

Table 18 is NOT the only Peake table for E39's-just M5s

That makes perfect sense Doug and is what I thought too. I have an M5 so I frequent this forum and saw that statement on the first page and it really needs to be corrected. I realize this is the M5 board, but the M5 is obviously not the only E39 and the person who wrote that should fix it as it threw me off for a while. Table 18 *might* be the only table you need for an M5 only should be more accurate and I don't even know where that statement comes from, but I have no reason to doubt it.

Thanks

Bill

Thanks Richie. This may be a dumb questoin, but are the O2 sensors in the engine compartment, or below the car?

they are in the exhaust, one before and one after the cat.

Not 100% on US cars, I think they are slightly different to EU cars but this is a link to where they are on my car;

http://www.realoem.com/bmw/showparts...74&hg=18&fg=10

Items 4 and 6, it is the same on the other side of the exhaust too so you will need 4 in total.

Most people do not change the after cat sensors as they do not really play any role in how the engine performs.

Only thing to watch for when replacing them - make sure you put some anti seize on the threads - or it will be the last time they get replaced!

HTH Richie.

Sluss-

Not sure why your codes are showing only 6 cylinders! (Ie Cyl #1-3)

Because of this, I am suspect on whether or not you are in the correct table...

In table 18, 50 is related to the secondary air system.

Did you try reseting the codes and see what comes back?

Also, are you sure all segments in the peake are working right?
