Now it's even a bigger challenge to find the root cause for your engine problems when a motor tuner has blurred the whole diagnostic picture with a new mapping of the ecu software. Now it is said - there are several different diagnostic paths that you could take - I would take a closer look at your ...

Hi Bram It takes some time to interpretat those VCDS log file you have taken.I´ve seen both log files and particular the last PICO Log file are interesting to study in details. There are a couple things that dont look right and here I´m talking about actual value versus specified values in the highe...

Hi Bram That's a tough challenge you are facing. Let me start by saying that I've have no solution to your problem - whatsoever. My first question will be - do you intend to diagnose this problem yourself ? My second question is - what diagnostic tools do you have availble besides the VCDS software ...

Hi Nelnun

The injectors you replaced are they new or used and have they been recoded with the correct IMA number from the injectors !!!.

Hi As seen in this wiring diagram which is from a Citroen 1.6 litre engine code ( EP6CDTX ), it's clear, that the primary ignition system are turned on and off inside the ECU and not at the ignition coil (COP). You used the attenuator on the picoscope which seen hindseided was wisely done if you don...

It a very good feature which I sadly not have been using before - but I will in the future. I have seen some videos where this function would be "the only thing to use" and here I'm thinking about cam/crank relations.

Its really amazing what this software can do.

Bjorn - That's a very high output voltage you got there.
No wonder that ecu get a high reading in terms of gram per second (g/s).

Bjorn - The outcome of your maf testing will show you what direction you should take. The maf sensor output voltage can be higher than 5 volt as seen in my case study here !!!

In that case it should be super easy to find It depends on how stable the Maf sensor signal are under test and here I'm thinking about glitches in signal - which of course is an easy task to see with the picoscope connected. If the signal looks good at the moment its being tested - it could lead yo...

Hello

This DTC P0103/ 16487 is set as soon as the signal rises above 5 volts for longer than 0.5 seconds (engine speed below 2000 RPM ).
