Hi, just checking was this working before and has now stopped ?

if so normally these pumps have a 3rd wire which is wired to IGN, probably best to check that its still got the IGN 12V signal.

the vw version of this pump has been known to fail from time to time and it might just need replacing.

Hi, if this is for the HV heater i posted the answer on the correct post below

hope that helps

Hi, looks like the coolant to heater is the lower pipe and heater to heater matrix is normally the top, depending on which way you heater is mounted. this is the diagrams from a e-golf and golf gte

i pulled these from the LDF files on the site. looks like there an extra value we can transmit which is ramp rate in a unit of watts per second. PTCe_01: 28, HCP4_uC2_1, 4 { TME_NV_PTC_soll, 0; TME_NV_PTC_ein, 8; TME_NV_PTC_Rampe, 9; } PTCs_01: 48, PTC1, 8 { NV_PTC_I_ist, 0; NV_PTC_P_ist, 8; NV_PTC_...

I'm confused. have you sent an output of 100% to your heater and only got an output of 2.5kw ? if so can i ask what voltage you where running the heater at ? as it does have a recommended power range.

muehlpower, thank you for all your work on this. Seeing the spec of the heater being upto 5/7kW. The LIN control message only has on byte for power level request, this means we can only request 2.5kW. Has anyone been able to get more out of the heater then the 2.5kW. Is it possible that Byte one co...

Hi, CAN bus and LIN run in different ways. Lin is a lot simpler. On CAN once the module has power it will constantly transmit its data regardless of if anything is listening. Lin works on a master/slave principal. so the master module has can transmit any control data it wants. but the slave module ...

looking at the circuit board it looks like it should be bi directional. think vwbrady mentioned it was linbus controlled so should be easy to control. if anyone has a merc we can connected to we can log the linbus and easily be able to control both the battery and dc converter saving tearing these t...

The HVIL or interlock is just a safety line which is used to shutdown the entire HV system if any part is unplugged. most modules this is just a pass thru the battery module is the originator. there has to be two 75ohm resistors (or one 150ohm) two emulate the motor and inverter A crash signal is tr...

hi as we don't have a Mercedes section i put this in general. has anyone tried this 48v battery with 12v dcdc converter ontop? looks quite interesting. looks like a bi directional dc converter going from 48 to 12v found these images on this site https://forum.esk8.news/t/mercedes-oem-l09-1-ev-batter...

I have attempted to log the powertrain data from an id3 but unfortunately it uses CAN-FD. now just waiting on a new can to usb with FD compatibility. also from what i read the module might have component protection rendering it useless.

I got my hands on an electric liquid cabin heater from a BMW F30 330E. I think its around 5kW. No idea about wiring and control yet. HV positive and neutral are through the large orange cable. Its has a thermostat on the outlet pipe. A 3 cable (Brown, brown/red & brown/white) connector then on ...

Ok that makes sense which bytes to send for which now whets the difference between start and Activate ? and there is a different byte for the RPM (speed) Byte 0 I'm making the HW ready and have a compressor laying around will try to send it at low RPM and see what happens since it isnt connected in...

Does anyone have a working code for heater control they are willing to share? still trying to get my head around lin bus and would love to see how others have implemented it, Thanks After making lots of adaptors and brackets im ready to start testing my AC setup. I decided to use a watercooled cond...

Hi all,

i have come across a EVCC from EV designs. price doesn't sound terrible

https://www.evdesigns.co.uk/evcc

what do you think ?

hi all take a look at " MLBevo_Gen2_MLBevo_HCAN_KMatrix_V8.18.01F_20190718_SE "

from viewtopic.php?p=52273#p52273

looks to have can frames from the mild hybrid

well spotted, i missed that and interesting the see the output of what can be assumed to be the 48v DCDC converter. if you can power your board and see what can frames you receive it might help narrow down the modules

nice, i want to buy one of these and control it via the canbus.

there's a few people online that have done this but unfortunately don't want to share the can frames

Great all i can say is a huge thanks, i dont know where your finding these but im sure they will save time on future projects. if you do find a lin module the receives the AC pressure sensor or AC compressor that would be interesting to look at and compare to what we have already discovered and know...

Hi Amazing great help thanks you

would you happen to have any other lin bus files, possibly climate control ?

Nice project, I have to agree with johu. do not pierce the insolation as the battery module measures the insolation resistance every 60 sec and if out of spec shuts down the battery. if you connect between the battery and inverter or to PTC / AC pump. the battery wont charge unless the ign is on. un...

Great work,

i have a VW brake booster. i will connect up the canbus and see what i can get-out.

on the mk3 golfs the ABS was completely independent , on the mk4 golf (same as the beetles) the ABS should still be completely independent its only if you have a ESP where it would listen for engine information (rpm, torque) to then send out torque limitations (when required).

Hi, I have come across this decode data from what is exchanged between vehicle and EVSE im sure its probably on the forum somewhere but i thought i would add it again just incase. Hope this helps :D image.png image.png image.png image.png Table F.3 – The physical/data link layer specifications for s...

Its a real shame to see you go, you have help many people on and off this forum including myself. so all i can say is a big thank you
