Re: What is the correct way to test the fuel low pressure system on a Skoda Octavia 1.6 TDI - CHLA engine type?

Just to round off the problems I've had with the fuel pump in the Skoda. I ended up changing the fuel pump, as it has driven 227,000 km and there had been a few times when the car had gone into emergency mode - so it was time for a new pump. Regarding the previously mentioned DTCs which I could not ...

Re: What is the correct way to test the fuel low pressure system on a Skoda Octavia 1.6 TDI - CHLA engine type?

Steve - I think you are right about my "measurement error". Somehow I must have enabled my zoom feature without being aware of this. I have made some new measurements of the fuel pressure before the fuel filter and they now show the correct pressure during the "Fuel pump actuator test" and start up ...

What is the correct way to test the fuel low pressure system on a Skoda Octavia 1.6 TDI - CHLA engine type?

According to the information I have from the Erwin Technical service system, there are two ways to test the low pressure system in a 1.6 TDI engine - namely before and after the fuel filter. A regular fuel pressure gauge (VAS 6551) is placed in series with the filter and the fuel pump is activated b...

Re: Bosch Denoxtronic 2.2

Hi Steve - Muttnjeff - Krabkakes I have found some training material from BMW which deals with a description of their SCR 2 system - which looks very promising in relation to the interpretation PWM signal. Whether there are any differences between the two systems - I do not know, but I do not think ...

Re: Misdiagnosis

Hi Steve Have you seen this TSB (SI B01 14 18) from BMW where the same DTC appears in the Ecu - as you experienced in your BMW. Here they are talking about replacing the EGR valve with the following spare part number (PN 11 71 7 810 871) on the warranty. I know your BMW Model X4 is not covered in th...

Re: Bosch Denoxtronic 2.2

Hi Ben I came across this tutorial document from Audi entitled "Audi 3.0-liter V6 TDI With Clean Diesel System - 941803", where there is a description of their exhaust gas after-treatment system and operation. What got my attention was the description of how the reducing agent pump V437 works regard...

Re: [Help] Motorcycle ignition waveform

Hi liviu2004 That's a typo on my part - it's of course 10000 microFarad. :wink: The charging system itself consists of a generator, a rectifier and a capacitor, able to accumulate energy for a short time and keep voltage as constant as possible. Without this capacitor you will not be able to start t...

Re: [Help] Motorcycle ignition waveform

Hi there I might be able to help you with some waveform of the secondary ignition system - not coil onplug system. This waveform is taken from a single-cylinder 250 cc Trial Bike (Honda Montesa 4RT) from the year 2007 and which I myself have ridden Trial on. This motorcycle from Honda was the first ...

Re: 2.0 TDI no start, audi a6

There is of course the possibility that when replacing the high pressure pump, that the timing belt is not correctly fitted according to technical data.

And here I am thinking of using the correct locking tool for the crankshaft and camshaft - it was worth checking again.

Re: PicoScope 7 Automotive Software

A comment about the latest PicoScope 7 version 7.0.73.8350 which I have tested today, where I have used the function serial decoding of a canbus signal. I mean - that this feature has become significantly more stable than previous versions and in my own little canbus test there was no dropout on the...
