powertube 625 fails after 1400 miles with temp error

[d3drturner]

Three lights flashing; no charge; on the bike it is error code 605

This after sitting inside overnight in 68 F temps.

Guessing the temp sensor has failed. Has anyone replaced one of these?

Apparently the 605 error can be due to ambient temperature being outside the permissible range or the battery pack overheats while charging.

Still under warranty?

Good luck resolving it.

Does your car fail every time the maintenance light comes on? The bike hasn't either. I suspect you have to reboot the battery system. Take the battery out, let it sit for a few minutes and reinstall. Your dealer or any Trek dealer can help you out.

take the battery out push the button on the battery for 15 to 20 seconds to reset the battery.

When looking at a potential $1000 repair bill, the first thing I did was web search the error and try the reset about 60 times over the course of a day in ambient 68 F temps with the battery on the test bench using every combination of button holding and pushing I could imagine. I tested the output voltage at 36.7 volts. It is out of warranty. There are no bosch dealers where I live.

Thanks

Correct.

Yes

 

[d3drturner]

Correct.


Yes

That's good to know. How did they replace it?
Or are you speaking of Bosch replacing the entire BMS?

bosch replaces the whole thing they don't do repairs.

you work for Bosch?

 

[fooferdoggie]

you work for Bosch?

nope just have dealt with them through my mechanic. Bosch always replaces something on or out of warranty with new. like my motor that rusted out a few months out of warranty. replaced with a new motor at no cost to me. non bosch repair places may do fixes but bosch replaces with new.

today I need to remove this snap ring.

Why in the world...

How did they replace it?

Remove the old one and put a new one in.
It could also be the balancer chip, but that would be a little harder to replace

That is awesome, but Bosch is really good when it comes to warranty even after 2 years.
If the motor was too old, there is a service kit that includes the right side motor cover with the main bearings and gears that usually go bad in wet conditions. It is only just over $100. I just fixed two motors the other day, pretty easy. After that, they are like new.

Also replaced a 2015 Performance Line the other day with a brand new Gen 2 Performance Line CX. That guy was so happy, he was already thinking about buying a new bike. But his old one is even better now than when it was new

thats what I needed when mine rusted out if bosch did not replace it. is this only for the drive side? on mine it was the left that rusted out.

 

[wildtrak]

is this only for the drive side?

Yes.

on mine it was the left that rusted out.

That is unusual, but happens.
There are a few small businesses in Germany / EU that actually replace all bearings if needed. A complete makeover is a little over 200€, which is very reasonable. Would be like $1200 in the US
