Hi PaPaSteve, I have been running my 2011 Leaf for six years now and love it. An original Japanese car with the white interior. I too have had the 12volt battery problems and seem to have a handle on it now. Normal car batteries are designed to provide high cranking current then recharge...

Hi Guys, An update... The heater is air mixing and the flaps continue to operate automatically even though there is no heat from the heater matrix. I will try a solid state relay which uses a big mosfet. The current draw is tiny but can switch 40A at 220/240 volts. It should operate from the...

There is a very interesting article here on how and why the water PTC heater fails (with links to two more articles and an informative video). https://tonyfowkesautomobiles.com/nissan-leaf-ptc-heater-repair/

Thank you for the replies. I intend to remove the (water) heater matrix and insert a holder for a bank of 12v PTC heaters conected to the 12v battery terminal through a fuse and relay. The air will blow through the PTC heaters in exactly the same way it currently blows through the heater...

Hi Guys, I guess I had a good one but the heater in my 2011 Leaf has finally failed. The error codes indicate that the control boards in the Eberspacher water heater have failed and probably taken out the 30A fuse. I have been half expecting this so am not majorly disappointed and pleased it...

Hi, There is a lot of misinformation in the industry about car chargers. I can not recommend anybody but can query your need to have wall mounted charger. I apologise for the interspersion of US terminology and clarifications but this a US Forum. The EVSE (electric vehicle supply equipment)...

Thank you for all the input guys. Unfortunately there has been very little support for older electric cars in the UK, even less in the backwater where I live. I am a 66 y.o. woman. I do not undertake these tasks for pleasure. I do it because I believe in electric cars, very much enjoy using...

Thank you for the info guys. Today I disconnected the TCU and fitted an Optima Yellow Top YTS 2.7 R Battery. I put a detailed write up on this thread:- https://mynissanleaf.com/viewtopic.php?t=33691 Best regards, Emma

So a lot more investigation later... Our local Nissan dealer knows nothing and have only done recall work on the few Leafs (Leaves?) in the area. They replaced one traction battery under warranty and due to lack of facilities hired a mobile crane to lift the car off the battery! :roll: But...

Interesting article. Thanks for posting the link. I read the comments with amusement... Boys shouting their toys. I drive a 2011 Leaf and get about 3.3 miles (UK) / kWh. If I wring it's neck it has about the same performance as a VW Golf (Rabbit) TDi but the fuel costs are about 1/4. It does...

Hi, I have noticed this too. GOM is always more optimistic when freshly charged 12v battery is reconnected. Last night I had a funny one though. As mentioned in my first two posts car has killed another battery (a cheapie off a well known auction site). I charged the car and unpugged EVSE...

Thank you Stanton. I will take your advice on board. I am not worried about error codes that can only be read by diagnostic/leafspy. I just don't want alarms/warning lights or anything that is not easily resetable. KR, Emma p.s. Cut wires can always be reconnected providing you leave a decent...

Hello, I live in the NW UK and have a Japan built 2011 ZEO with a Muxsan 11kW range extender. (68,000miles and just dropped to 9 bars on battery indicator.) Like many owners I have been having problems with the car killing the 12v battery in short time. I fitted a new 12 battery when i bought...

Hello, I live in the NW UK and have owned a Japan built 2011 ZEO for 5 years and have run a 11kW Muxsan battery extender for 2 years. The car has covered 68,000miles and just dropped to 9 bars on the battery indicator. I purchased my Leaf as soon as I could afford to having been a believer in...
