Help Needed: BMW Error Codes P17E1 and P17E4 - What Should I Do?

Seeking Help with Transmission Issues

I’ve been having some serious problems with my BMW, and I need your advice on what to do next. Recently, I got these error codes: P17E1 and P17E4. From what I understand, these are related to the transmission, and it seems like I’m not the only one dealing with this.

Symptoms I’m Experiencing:

  • The car isn’t moving properly when I shift into drive.
  • There are times when the car reverts to park or neutral unexpectedly, which is really worrying.
  • I’ve noticed a bit of a delay when accelerating, and it feels like the transmission isn’t engaging as it should.

What I’ve Tried So Far:

  • Checked the transmission fluid levels; they seem fine.
  • I’ve done a visual inspection to look for any obvious leaks or damage.
  • Tried resetting the battery to see if it would clear the codes.

Despite all these efforts, the error codes persist, and I’m at a bit of a standstill. I’ve searched through various forums and threads, and I’ve seen mixed information about potential fixes.

Questions for the Community:

  1. Has anyone successfully resolved these error codes? What steps did you take?
  2. Are there any specific parts or components that are known to fail and cause these codes?
  3. Is there a way to clear the codes permanently, or will they keep coming back?

I really appreciate any advice or insights you can share. It’s tough navigating this on my own, and I could really use the community’s experience to help guide me through this mess. Thanks in advance for your help!


I’ve been getting error code P17E1 on my BMW and from what I’ve read, it refers to an issue with the power management system. It could potentially affect your vehicle’s performance and fuel efficiency.

That’s interesting! I’ve been dealing with P17E4, which seems related to the same system. It might be worth looking into the wiring harness as a possible culprit for both codes.

P17E4 indicates an issue with the battery management system too. Both codes suggest a problem with how power is distributed. Have you checked your battery health?

I see a pattern here. It’s like they are best buddies of trouble codes! Definitely check your wiring and battery condition.

Yeah, these codes could significantly affect performance. If the battery isn’t charging effectively, it might lead to electrical issues while driving. It’s best to get it checked soon!

That’s a good point! Has anyone had success fixing these codes with a simple reset, or is it usually more complicated?

While a reset may clear the codes temporarily, if there’s an underlying issue, they’ll likely return. It’s best to diagnose and address the root cause. Has anyone found a specific fix that worked?

I tried resetting mine, and it worked for a couple of days. But alas, the codes came back. It’s like my BMW is playing hide and seek!

It seems we are all in the same boat! I wonder if this is a common issue across multiple BMW models. They should come with a warning label: “Caution: prone to error codes!”

Classic BMW! It’s like they need a hug before they let you drive. Anyway, maybe we should all head to a trusted mechanic together. Safety in numbers!

Definitely supportive! It’s worth visiting a knowledgeable mechanic who can perform a full diagnostic. Fixing these errors will ensure better performance and peace of mind. Keep us updated on what you find!

I’ve been dealing with P17E1 and P17E4 for a while now. The car often struggles to accelerate, especially when going uphill. It’s frustrating!

I totally feel you! My BMW started showing those codes, and it stuttered during takeoff, too. I found it triggered mostly in colder weather. Ever experienced that?

Those symptoms sound familiar, especially the acceleration issues. P17E1 usually relates to control modules malfunction. Have you checked your battery and connections? That can often trigger these codes.

When I checked my battery, it was fine, but I did have some issues with the connections. This could be a common trigger! Did you reset the codes after checking?

I had these codes pop up, and it turned out to be a faulty sensor. Typically, the check engine light would flash, and my fuel efficiency tanked. Have someone run a diagnostic ASAP!

Great advice! I’m curious, was it a specific sensor causing the issue? I’d like to know what to look for in case mine is acting up.

Yes, it was the mass airflow sensor! It’s amazing how much of an impact it can have. Once replaced, the error codes disappeared! You should definitely investigate that if you’re facing similar issues.

Wow, that sounds like a simple fix! I hope mine is that easy. I just want to get back to enjoying my drive! Here’s to hoping it’s not a bigger issue.
