    12V battery died

    The jump leads are fine to tickle it awake. A jump box is designed to jump start a car not recharge the battery. Also get one with an override on sensing a battery. Many won't provide a jump until they sense a battery is present which they won't do if the battery is dead or disconnected.

    12V battery died

    There was a problem with batteries going dead due to faulty monitoring but there is a software update to solve that so the HV battery keeps it topped up. The battery doesn't actually go flat. It gets disconnected when the voltage drops to prevent it going flat. The boost process through the...

    Had it two days and crashed it 😱

    Surprised the automatic systems didn’t warn you and then stop you especially since you seem to have hit one of its sensors dead centre.

    Bleeding Brakes

    Yes, the switch to mechanical brakes occurs IIRC at 3mph.

    Can a OPC retrofitt ACC?

    https://www.afterone.co.uk/. Good guys and did mine. Not sure looking at their website that they do the Taycan ACC anymore but worth a call to check.

    Bleeding Brakes

    The feel in a Taycan has nothing to do with bleeding the hydraulic brakes. The brake pedal is connected by a wire to a computer not the hydraulics. The feel is defined in software and is similar to other ICE Porsches with direct hydraulic brakes IME. My Cayman for example feels similar and...

    Bleeding Brakes

    You’d better contact Porsche to let them know they don’t know how their brakes work. https://christophorus.porsche.com/en/2022/403/technique-taycan-energy.html The Taycan is brake by wire - the pedal is not connected to the master cylinder but to a computer that works out how much regen and...

    Bleeding Brakes

    Bleeding the brakes won’t help. That is how the pedal feels. Apart from the first mile after a cold start, the final few mph of a stop the car doesn’t use the mechanical brakes. It’s all done by the electric motors not the disks and pads. The only exception is if the braking exceeds the...

    Can a OPC retrofitt ACC?

    I don’t think Porsche will do it for you but there are places that will. I had mine done by a third party and it has not caused any issues with the warranty or software upgrades. In fact the local Porsche dealership has had it in a couple of times, both related to related sensors, and didn’t...

    Retro Fit Adaptive Cruise Control

    Been into Porsche for a number of warranty things including software updates and sensor problems but they have never raised it. Nor have their or OTA updates caused any problems.

    I Rebuilt a £120,000 PORSCHE Taycan: 2nd Post (finally)

    Except the battery on any other car won’t kill you if you get it wrong.

    Recuperation mode?

    To add to the above, the car uses the motors to do most of the braking and put the energy back into the battery. The only time it uses the mechanical brakes is if the battery is full and won’t accept any more input from the motors braking, the last few mph when you are coming to a stop, you...

    Recuperation mode?

    A mix. According to Porsche off is the best for energy efficiency. I have it off on long cruising roads. I switch it on for controlling speed downhill and I switch to Sports+ mode for driving twisting roads. It has a much stronger regeneration in that mode - more like having engine braking...

    NHTSA Complaint - Navigation map out of date - April 22, 2026

    That’s why I use Google Maps or Waze. Porsche navigation is poor too.

    Looking for advice. Can I go on vacation with fried OBC?

    I use Google/Waze and transcribe the charging location from the Porsche charge planner and then switch the charge planner off but keep the Porsche nav in the speedometer screen for the map that shows the boundary of where I can get to on the current charge.
