I wouldn't call broken wires in the door hinge a common thing but it certainly isn't rare either. Well done so far and good luck repairing them :)

Diagnostic tool recommendations C5 Aircross

by tightlinessteve » 05 May 2026, 21:24

First post

Hello,
Apologies if this is a repeat question, but I have been looking around the forum and not found an exact answer. Could anyone advise on the best software/OBDII reader for my C5 Aircross 2019. I'd liked to change my rear brake pads and understand I have to cycle through a brake reset and I plan to change my gearbox oil and read that I have to...

Last post

Main questions would be what’s your budget and are you wanting something for different makes & models or just PSA?
Most half decent diag tools now will do service procedures like putting EPB’s in service mode DPF regen etc.
Diagbox functionality will be limited on a car of this age without an online connection & subscription.

PSA interface

by RSJ » 12 Apr 2026, 16:57

First post

Hi guys,

I have a Lexia interface from around 2006 or 2007. We bought this new back in the day, it came with a laptop and cost roughly £3,000, so it should be a genuine unit.

I haven’t used it much over the past few years, but I’m getting back into this line of work, so I thought it might come in useful again.

To be blunt, even though we bought...

Last post

Mine does have the blue port, however right or wrong, i've been told that the very early ones did.
This was bought as a genuine unit by us back in around 2005 or early 2006, I'm sure.
It's just reading everything on line you don't know what to listen to and what to ignore.

Im not sure this evolution style interface even came out till around...

Is this 'full chip'?

Last post

Yes 0603 is physical size, meantime following Paul-r's info, my local service for electronics did soldering for my full chip clone from aliex, which sellers usual declare as full chip ABCD, but in practice many times missing this resistor 10k, so local electronics service soldered SMD type resistor 10k with label 103 on top of resistor.

issue with turboposition sensor (P2565)

by peyvey » 04 Apr 2026, 11:07

First post

Good morning users

I have a problem with my turbo position sensor on my Ds5 hybrid p2565.
Apparently the engine computer thinks that the value it gets from that sensor is no good. The value should vary depending on the amount of vacuum the E-valve is applying.
The values i get on my sensor are 1,4V (when no vacuum is applied) to 3,4V (with full...

This post is in sequence to my other post (issue with turboposition sensor)
Maybe it is of use to anyone dealing with the same issue

After reading some other posts on the same problem i came to the conclusion that the sensor had to be replaced.
With great effort i got the old out and the new one in only to find that it gave the same voltages

Hello,

I have a problem that bothers me for some time with my Citroen C5 2011 1.6HDI. I went to some Citroen authorized services but none of them are willing to help me, they just took my money and that's it.

Could anyone provide me with a link to a good lexia device complete with good working software (may be for older laptop) for my Peugeot 508 1.6 bluehdi automatic of 2016, and when possible also usable for my 308 1.6 bluehdi automatic of 2017?

Last post

If I may say my experience with diagbox. I've used several laptops designed for older operating systems like Windows XP or Windows 7, but I ended up getting a used laptop designed for Windows 10. It seems to me that it is best for you to use the newer diagbox version 9.85 and beyond. I took this device:
