Guys, This is the engine: M276 DE30LA as its full name. Found on W212 E400 and S-Class of the same era and also W205 C43, C400 and C450 in increased HP. The GDI system is very similar to the M157 AMG. https://mbworld.org/forums/attachments/w212-amg/422654d1572139897-e63-s-4matic-m157-factory-wis-mai...

For those wanting to see a more complete description/workings of fuel filter system of W212 E400, I don't want to waste this forum bandwith by posting here. You can read here : https://mbworld.org/forums/e-class-w212/841642-tank-fuel-filter-change.html It's link to another post ( Main original post)...

I gave up trying to "correlate" the VOLTAGE OF FUEL PUMP as reported by Xentry to actual duty cycle using Pico waveform. It is also a weird thing that Xentry shown amperage of the fuel pump , is not the same as my measurement on the fuel pump main power input wires. I got confused or misled by "bad"...

I will report back when I can scope the fuel pump controller while doing 1st and 2nd gear WOT. I think that is the only way I can at least "correlate" the VOLTAGE OF FUEL PUMP as reported by Xentry to actual duty cycle using Pico waveform. The newer AMG version E63S 2019, has better N118 fuel pump c...

Thank you so much Steve. I have to learn more on the math channel use and apply your thought process as a good advice on how I may be able to predict the fuel filter life...awesome. For now I shall include how Xentry or Autel shows the available data perimeters coming out of N118 fuel pump controlle...

EDITED , my bad..I have MS One-Drive : https://1drv.ms/u/s!Ahrq0GmYQf8dghwpWVBochi0huJJ?e=EN1shM The waveform is not during a moving test drive, but a stationary one with some engine rev up. The one below I can not scope it during a test drive. So no waveform. " Autel or MB Xentry does not show dut...

Hi All, Thanks for the excellent post by Steve https://www.picoauto.com/support/viewtopic.php?p=100521#p100521 I would like to add some information and also seek advice. I am a complete newbie for scope use :oops: Information on the 3 phase BLDC pump in this post : https://automotivetechinfo.com/wp-...

Hi Steve,

All good now. I swapped with a new 4425A.
Super service from AESWAVE, Mr Carlos Menchu and team.

Thanks

Thank you Steve. I must be in bad luck. My 4425A has a bad 4th channel, the D. Probably cold solder joint somewhere. Press hard and keep pressing on the BNC+ connector and only then the signal and the auto-recognition BNC+ works :oops: , Bad QC on this one. I am discussing with AESWave* ( *where I b...

Hi All, I got the baby pico 2205A for a few months now and somedays back the 4425A. I am just a DIY hobbyist for my own cars. I hope to be able to contribute some waveforms sample soon in the future and at the same time absorb the know-how from the seniors here :mrgreen: Have a good New Year everyon...
