Hello

I have E300 blueteck hybrid.
No error in instruments cluster.
when i read errors in xentry i get this error
P0A8000 The hybrid/higt-voltage battery module must be replaced.
the car runs fine.
How can i delete this error without change the hybrid battery?

Thanks

You have Xentry, the best tool!

Have you tried to reset the faulty module: yes/no ?
Any worthy hints in code settings criteria ?
How about troubleshooting steps?

Obviously the car is telling you it wans parts - You best bet is to gain knowledge about what causes that fault -

Personally I am not positively impressed with Benz electricals. They purposely build GND poorly to surge circuits.
Case in point the single main chassis-engine GND strap is located on the lowest undercarriage point, totally exposed without any cover protection, right near glowing hot catalytic exhaust. That clearly spells maximum heat and oxidative stress.

Less than half priced Japanese cars have dual redundant GND straps mounted high under the hood. The total opposite of W212 chassis.

You can expect something as simple as a factory painted GND to skew voltage measurement and disrupt a SAM power manager.

Perhaps you are graced with a short lived fake AUX module built with a couple FARAD CAPS. They get carbonized by power surges provided by poor grounds.

I reset many times the error code, immediately the error comes buck.
I do all the test in (test) section in xentry, everything looks fine.
the hybrid battery looks works fine, but the error still there :-(

You confirm Xentry alone is not smart....that's when it pays to know your tools.

"Code setting criteria" can provide understanding when resets are no joy.
