Hey guys, please see the photos below.

A little backstory:

1. I would get engine malfunctions quite frequently and would just turn off car and turn it back on and it's fixed. (for years) and not like every day .. maybe once or twice every few months.
1.5 - Also I specifically would notice if I went to certain "shittier" gas stations it would happen more frequently than better gas stations, which I assume was an octane issue. Again I always assumed the engine malfunction was a safety issue related to the turbo and the car sensing something and making sure the engine didn't blow up.
2. I recently had the water pump replaced.
3. Today has been hotter than normal, and on my way home my engine malfunction did not go away after restart until I got into cooler climate.
4. I've noticed in the past my engine malfunction would come on if I was in 6th gear and at 2.5k RPMS and gave it some gas ..
5. As for TPM malfunction and Restraint system malfunction those both just came on one day and never went away ... not at the same though and with no real warning or reason.
6. Also for the record when this would happen before I always assumed it was some kind of overboost issue or something where the engine reduced power because of that happening - no idea if there's any truth to that.

When I got the car diagnosed by BMW when my water pump went, the guy said he thought my battery thing might be going which is why my TPM malfunction and restraint system malfunction thing was going on. I forget the name of the item but it's the part thats on the battery - he didn't know for sure.

Here are photos of the current "Check Control Messages" and a print out of the Diagnostic from BMW from 2 weeks ago when my water pump went.

No one has any input?

I had to go to Realoem to figure what make and model your car is.
and the paper says 169K km or is that Miles?

you car is a 2007 335i Coupe.
Is your Car Modded at all? what Mods?

Questions:
1) Have you ever had a Walnut Blast?
2) Have you ever Replaces or Cleaned and swapped your Vanos Solenoids?
3) When was the last time your Plugs and Coils were replaced? (what brand?)
4) When was your Battery Replaced Last and by whom? (was it registered?)
5) On the HOT Day what was your Oil Temp showing? what is it normally?
6) When they did the Water Pump, did they do the Tstat also or not?

You have a lot of Electric Codes, so I would listen to your Dealer and get your Battery Cable replaced. there is a TSB on it. But get your Battery Checked also.
you Can't test your Battery with a Faulty Battery Cable, but quite a few people have reported the Battery Cable as the Issue and it just causes a lot of Electrical Gremlin issues.

As for the Battery, if you are going to replace it, please make sure you register it, else that battery is not going to last as long as it should.

Easy things you can do your self:
Clean and Swap your Vanos Solenoids. there are 2 of them, Intake and Exhaust.
look up DIY of N54 Vanos lots of videos. it take 10 min to do.

I would not do anything else until my Battery and Voltage issues were addressed.
Once done, then
reset all Adaptations, and Clear all Codes in Memory.

JUST an FYI that most people do know yet, that BMW still used Bosch Plugs. But switched to Delphi or Edor brand Coils.

PM me or update here.
Good Luck.
PS: can you diagnose your car yourself or not?
do you have an Apple phone or Andriod?

I had to go to Realoem to figure what make and model your car is.
and the paper says 169K km or is that Miles?

I have 106k Miles on my car right now ... so that must be in KM .. b/c i was wondering wtf was going on there as well. That print out is probably 500 or 1k miles ago

you car is a 2007 335i Coupe.
Is your Car Modded at all? what Mods?

Not modded at all, original owner did up the boost and have suspension on it, but then he put it all back to stock when he sold it to me. Car had like 25k miles on it at that time.

Questions:
1) Have you ever had a Walnut Blast?
No

2) Have you ever Replaces or Cleaned and swapped your Vanos Solenoids?
No

3) When was the last time your Plugs and Coils were replaced? (what brand?)
I actually replaced my plugs like 20 or 30k miles ago with OEM brand from ECS tuning ... I replaced only 1 Ignition coil because it was bad (i probably should have done all of them) .. and again some OEM brand from ECS tuning can't remember exactly, but I def don't cheap out.

4) When was your Battery Replaced Last and by whom? (was it registered?)
Super weird story, I had my care stored by some scumbags in South Florida when I was in a REALLY tight spot out in CA. Came back and realized they put a battery in there smaller than what it should have, arrived home to PA where I live now ... and had to have the battery replaced. I believe I just got some standard Duralast or whatever type battery. As far as it being registered? Not that I am aware of b/c it didn't happen at a dealer. From the time I've had this new battery until now has probably been almost 3 years. Also I have seen this issue with older batteries too.

5) On the HOT Day what was your Oil Temp showing? what is it normally?
It was slightly above the 220 mark, maybe 230/235 ... I think normally it hovers around 220

6) When they did the Water Pump, did they do the Tstat also or not?
Yes they did, I bought both from ECS tuning, bought the whole kit.

You have a lot of Electric Codes, so I would listen to your Dealer and get your Battery Cable replaced. there is a TSB on it. But get your Battery Checked also. you Can't test your Battery with a Faulty Battery Cable, but quite a few people have reported the Battery Cable as the Issue and it just causes a lot of Electrical Gremlin issues.

What's the TSB? Ok I will check my battery cable.


As for the Battery, if you are going to replace it, please make sure you register it, else that battery is not going to last as long as it should.

OK ... does the dealer have to do this?

Easy things you can do your self:
Clean and Swap your Vanos Solenoids. there are 2 of them, Intake and Exhaust.
look up DIY of N54 Vanos lots of videos. it take 10 min to do.

Will do

I would not do anything else until my Battery and Voltage issues were addressed.
Once done, then
reset all Adaptations, and Clear all Codes in Memory.

Will do

JUST an FYI that most people do know yet, that BMW still used Bosch Plugs. But switched to Delphi or Edor brand Coils.

OK

PM me or update here.
Good Luck.
PS: can you diagnose your car yourself or not?

It's theoretically possible but I don't have any code readers and not sure what other tools I'd need, but I'd get them.

do you have an Apple phone or Andriod?

Yes I have and iPhone and old android laying around.

Thank you for the responses - AMAZINGLY helpful!

Here's info about the battery cable TSB: https://blog.bavauto.com/13516/bmw-r...e89-13v044000/

Your dealer should also be able to get the details from BMW NA directly. Registering a battery is important -- if the cable isn't at issue, I would look at that next. Get a fresh, quality battery (I like Costco batteries if you have a membership) and get it registered when it's installed.

I wonder if they did this recall on my car? I remember they told me I had a few recalls one day and they performed them.

I don't have any costcos near me.

I found such a Negligible price difference between After Market and OEm Batteries at the dealer.

1) Follow up on the Battery Cable TSB and let us know, if it has been addressed. call or go to dealer and specifically ask if this TSB was done.
TSB means: Technical Service Bulletin.

2) Your Oil TEMPS are perfectly fine at that Temp.

will update later tonight remaining points.

Start Looking up Walnut blasting in your area or Dealer ASAP.

Questions:
Do you DIY or not?
Do you have K+D Can Cable or not? (VERY Strongly Recommend this)
Do You have INPA set up on a Laptop? (VERY Strongly Recommend this)

or

this will save you a lot of Diagnostic time

DO you have an Andriod phone?
can you get a old one?

OK so quick update!

I ordered both cables. I still have to do the TSB thing.

But today I cleaned my Vanos Solenoids. I believe they were dirty .. they were like filled with oil. Also on the front end of my motor there was tons of built up gunk.

BUT the CRAZIEST PART OF THIS WHOLE SOLENOID JOB IS THIS!

For probably over a year I thought I had "Turbo Rattle" ... when I was on the gas I wouldn't hear anything. But when I let off I'd hear a rattle, like a leaky exhaust rattle. I figured it was the "turbo rattle" and that my wastegates were just rattling when they let the exhaust gases exit while I wasn't giving it gas.

After cleaning my solenoids and reinstalling them the "Rattle" is gone! This means my FRIGGING Vanos solenoids were leaking exhaust gas for probably almost two years! HOLY F***. The bolts for the solenoids were a little loose.

I'm stoked that that "rattle" is gone now but I can't believe that was happening for so long, I never even knew it was a possibility.

Anyway, the car is running a little smoother with me cleaning the Solenoids. I am still getting the engine malfunction under hard acceleration in higher gears like 3+. My car seems a little peppier too now .. but that's probably because I was leaking boost from before.

Also I remember last time my "Coil Spring" went bad my car was having engine malfunctions, then one day I just floored it and the bad coil spring died. I thought I broke my transmission since my one cylinder wasn't firing (I didn't know that at the time but it was a ll jumpy) so I wonder if the engine malfunction is something related to ageing coil springs - something I will keep in mind.

Here are the photos from today:

[BashShah]

Clean the Front of the Engine.
Clean those Vanos Electrical Connector.

If the Front of your Engine is Dirty with oil, chances are you have a OFHG Leak.

If your Coils are Bad, and you plan on changing them, them switch to Delphi Brand or Eldor.
These were the Updated Brand from BMW.

[pjr710]

Clean the Front of the Engine.
I wiped it down pretty good

Clean those Vanos Electrical Connector.
I did .. I used brakleen and contact cleaner

If the Front of your Engine is Dirty with oil, chances are you have a OFHG Leak.
what is the OFHG? I didn't have a ton of oil i saw little drips which I assume was from the solenoids

If your Coils are Bad, and you plan on changing them, them switch to Delphi Brand or Eldor.
OK, how do I know if they're bad though? To my knowledge they are all working, when the last one went bad it just totally stopped firing on the cylinder and my car was like undrivable and jumpy.

These were the Updated Brand from BMW.

[BashShah]

OFHG - Oil Filter Housing Gasket

I have never heard of VANOS Leaning Oil.
BUT OFHG leak and it goes down and may spread and onto your BELT some how, ohhh and dirt splash....and it gets clumped and gummy.

if you have 169K km on your Car, and you are on original Coils...and PLugs.
I don't care how your Car is running, CHANGE all of them. (you are waiting for a problem to occur)

[pjr710]

I used INPA today and read the codes, then cleared them, then re read, then cleared, turned car on .. did the same.


This was the final result with the car on and after clearing a few times.

Can someone help out with how to read this .. I was checking out some of the errors online but i dont fully understand what it all means yet.

[pjr710]

OK so from doing more research .. I guess these are the only codes that are sticking with me right now .. i wonder how frequently I should check for codes?

I figured out these are from my TPM (do I just replace these sensors?
- 6051
- 6053

These ones are related to fuel pressure and radiator?
- 29F3 (not sure how I'd fix this one)
- 2F0D (could this mean I have to bleed my coolant?)

These ones are the most troubling, mostly because I specifically remember when I got my car aligned my cruise control stopped working and someone told me it was because my "Steering Angle Sensor" wasn't reset. Cruise still hasn't worked, and I don't have hill control (my car rolls back) ... I've been living with it .. but how would I fix these?
- 5E34
- D357

Also I see "E0" come up but not sure what it means. I assume it's something that can't be counted?

EDIT: Just went for a quick drive and tried to get the engine malfunction.

These are thew new codes, I got in addition to the ones above, I already looked them up but interested in possible solutions/diagnosis.

- 2E8E (this one makes me think I have some electrical issue, my windsheild washer fluid doesn't spray out and I have a chopped off fog light wire - could either of these cause this?)
- 30FF
- 3100
- 604E (this is another TPM one I believe, so 3 total now)
- A468 (this one seems weird, I do have a ripped BMW nav DVD from the original owner so maybe that has something to to with it? not sure)
