2007 E86 dead power steering!

[rocky79]

Hello,

The EPS ( electric power steering assist) light came on and my steering wheel became very heavy.
I have checked the EPS fuses, everything seems fine. The battery seems to be fine.

I didn't see many DIY post on this topic. Some of the search results was pointing to controller failure but I would like to see if anyone here has experienced similar issue and how they solved it.

Thanks in advance.

Scan for error code in ecu. Hopefully it is not complete servo unit and column.

Hello,

Thanks for the reply. I already scanned it, however it couldn't connect. No communication with the steering controller.

It's been 2 years and got used to manual unpowered steering but now I really want to fix it.
I thought I would check if this happened to anyone and if there is a DIY fix.

It doesn't look like it's common. The electric steering works fine when It's driven for a while on a hot day.

Thanks in advance.

This is the vender who will re-build the EPS: https://www.ecutesting.com/product-c...ower-steering/

The vender is in the UK but, does world-wide customers. I'm not sure if there is a specific D/I/Y on youtube on this, But, I've read a guy's posting on the UK Z4 forum that claims he can take one out in an hour and then reinstall it in another hour.

Thanks for the reply.
Yes, I saw their service before, they also sell on eBay.
I will have to take the motor out ship it and wait. At that point it’s probably much simpler to have a shop does it.

Seems like any variation of Z4 gets major respect in the Uk and it’s popularity there means that one can get stuff like this fixed easy peasy. I think roof motor repairs and relocations can be had for great prices too.

I Agree 100% and this is why I follow the posting on the UK's Z4 Forum. They attempt to repair parts which are generally simply tossed in the trash here in the US. I've gained a lot of respect for their D/I/Y postings.

Interesting observation. Thanks for sharing.
