Not aware of that being an option in diagbox, but you can achieve that just by unplugging all the injectors, or crank/cam sensors, or pulling the fuse for the fuel pump - the engine won't start without those.

Hi. I’m having a little trouble clearing fault codes on Diagbox . It keeps on asking me to set up an after sales zone . I try but it keeps on failing. I can clear faults on individual ECU’s . Using a set up from Easydiagnostics. Many thanks in advance for my help

Last post

I have taken the car up to our local garage in the hope that he would be able to connect to the engine ecu and reset the Eolys tank level after we have filled it and also tell the car that it’s had a new EGR valve . He can connect but cannot erase faults or tell it that the tank and the Egr have been sorted. It’s exactly the same as Diagbox at...

Hello fellow French car Forum members. I have just had diagbox software loaded on to my laptop. My next step is to find a member here on the forum who can advise me where to purchase the cable that goes from my laptop to my obd2 port. Can anyone help. My deepest thanks to anyone who replies in advance.

What version of Diagbox software are you running? Is the hardware full chip?

2013 Peugeot Partner HDI - not a mechanic, just a driver hoping to learn.

Sometimes the car does not start first time when the engine is cold. It turns over and the engine management light comes on. I wait about 20 seconds and the car starts. The car usually starts fine the rest of the day.

I also get occasional loss of power when driving....

Looking at the screen shot I'd say get a new one , also check the loom

Hi, is there any site where I could download the 7.57 update for diagbox? Most updates I have found are either 7.57+ or paid.

Last post

The tool exists; back then, I even received my appdiag.sys file via email to unlock the Expert tab. Today, the 7.01 ISOs are either all unlocked, but incorrectly, meaning the Expert tab and troubleshooting are no longer available.

Hi all,

I've accidentally updated my Lexia 3 interface from version B to C (firmware 963830C), using the PSA Interface Checker, and now it no longer communicates properly with PP2000 or DiagBox.

I need to roll back the VCI firmware to 921815B (appli.com 4.2.4), but I can't find the downgrade file anywhere I've looked.

If anyone has the 921815B...

You may find diagbox 5.0.2 here but no guarantees!! :-D

Which Diagbox to buy?

Hello, could you please give me a link for a full chip reliable Diagbox? I will work on Citroen and Peugeot up to 2015-2016. I found a lot of links, but everywhere I can find bad reviews. Maybe someone bought it recently and can help me? It doesn't matter if it's eBay, AliExpress, UK, or Europe. Thank you.

This will it more complicated to choose!
Just buy the one i advice, because if you buy it, you get the hardware, cabels and software all in one box.

Hello everyone,

I have a 2015 208 GTI

I own a 2015 model 208 gti. I bought the car second hand about a year ago. The previous owner of the car had replaced the original ECU at the Peugeot service due to a malfunction. I started getting malfunctions in my car about 3 months after purchasing it, it cuts off the gas at low speeds and suddenly...

Last post

Yes, I’ve also added that to the list of possibilities — it’s quite likely that something was temporarily resolved just by disturbing a connector during the ECU replacement.

Additionally, according to PSA technical documentation, when a brand-new ECU like the Bosch MEVD17 is installed, it enters a “learning/adaptation phase” where it gradually...

Can I use my VCI for Diagbox to read basic error codes on any car?

Hello, quick question. Ive got a Citroen Relay so I've got the OBD diagnostics hardware for it and I use it with Diagbox and it works great. Just wanted to ask if I can use the same hardware to read fault codes on other vehicles, using it as a basic ELM 327 interface, with a more generic piece of software for Windows? Is that possible? Or do I...

Last post

With the Lexia 3 hardware interface and the diagbox program, only Citroen, Peugeot and Opel can be tested. There are cheap universal adapters for reading and erasing errors.
