I have done something silly. C6 content.

Thanks for the words of encouragement all, it gives me strength to know the AS massive is behind me, or laughing at me or whatever.

Right then, what have I bought... First order of business was to try to get my Lexia clone to parlez avec le grand citro(e)n. It turns out when I bought it I didn't go for the 'full chip' version, which means there's stuff missing on the PCB. Shame on you, past self. The internet said I might be able to get it working by adding a strategic 10k resistor, like so:

This still didn't work, so I tried my Delphi clone instead. This also mostly didn't work, although it did briefly communicate with the ABS ECU, confirming the information from the seller about a faulty ABS sensor. The other thing that happened as a result of my diagnostic antics is that the car got excited, and now the spoiler is like this:

No idea how or why that happened, I guess we'll have to wait for the full chip Lexia to rock up from China for the full mysteries of this car to be revealed. Not to be put off, I thought I'd try to measure the duff ABS sensor with a multimeter - should be easy enough right? Err... no.

The connector lives underneath the main electrical junction box in the engine bay, so all sorts of shit including the ECUs, fuse box etc has to come out to get to it. So it begins, hopefully this isn't an ominous taste of things to come. Here's the connector, from factory just cable tied up under all that mess:

The sensor is shorted, so I'll try to pick one up tomorrow and get it swapped over. Place your bets on how many, if any warning lights this will extinguish. The seller assured me that the electronic handbrake failure message was also down to this sensor.

Had a general look around with it in the air, didn't see anything too horrific apart from this tyre:

Yikes, I drove the car back to my unit on that. I also found a very shagged drop link on the back, which hopefully explains the horrific rattling over bumps. The suspension generally wants a refresh on the back, which I'll do once/if the electrics are sorted out. The good news is the car came with a free GoPro:

So far, so bad. I've caught myself just looking at it a few times, it's quite something. Hopefully it's not too ruinous to fix.

Excellent.  How many C6s are there on AS now?

Not as many as you’d think.

The one picked up on here for ‘scrap’ money a couple of weeks ago is currently on eBay…. 🤨

Failed abs sensors cause a bucket load of errors across multiple ecu's. 

Front sensors are a dodle to replace. Rears are a pain to do properly, fuel tank needs to be dropped. 

C6's are fabulous when they are working. 

Definitely invest in a fire extinguisher 🔥🙄

Oh god, was that yours that was referenced earlier in the thread? I saw the thread for it when you bought it and was mighty jealous, I'll have to find the thread and catch up with exactly what went down. Sorry for your loss and all that 😥

I managed to pick up one of GSF's finest cheap ABS sensors today, so I set to it. The old sensor had to be drilled out, I expected nothing less.

Wham:

Thank you ma'am:

Took a bit longer than I hoped because I was scared of going too far and damaging something, but it turns out that would've been quite hard to do and I should've just sent the drill through. Ah well! My reward is this:

That's right 'shiters, no warning lights. Handbrake working. Living the dream (or something). I should never have doubted the seller on the handbrake, but once bitten twice shy and all that. The low fuel light is genuine, so if I can actually find any fuel that should sort itself out. I'm going to order all the bits for the suspension and a service tonight, then probably look at sending the spheres off to be checked/regassed. Do any hydropneumatique lickers have any experience of this or should I just stump up for new ones?

Also, check out the mood lighting. I didn't notice it at first, which I really like. No bright colours like you get in modern stuff here:
