If you get down near Congleton with the car for any reason let me know, just got my Diagbox working again this afternoon (amazing what one can do if one is forced to!) and sorted out one of our 206s. Not the most experienced with the kit, but I've done some basic programming of BSI functions and code reading/fixing on the PP2000 side of things & happy to take a look if you're in the area any time.

That's very kind of you, thanks! I see you're about an hour and 15 mins from me, so I might take you up on your offer if I can't find anyone a bit closer :)

Having taken it out for a good drive again today without any of the original issues, I'm starting to feel a bit more confident in the car (and have grown quite attached to it!). It's a nice relaxed drive. I think the thermostat might need replacing as the cabin didn't get very warm even with the climate set to 28+28, and the fuel economy didn't seem great at 27 mpg over 14 miles each way (mix of town driving and long sweeping country roads).

Yep not the closest unfortunately, but if no other offers forthcoming let me know. These cars really do grow on you after a while, careful you don't wind up with 4 of the things like we have with the 206 haha! Never had anything new enough to wear an x07 badge but if it's even half as comfy as the 405 and 406 before it then you'll need to take extra measures to stay alert on longer trips, such was the cosseting nature of the examples of those I've owned!

The heater doesn't sound that great nor does the economy, though I have noted our 1.4HDi's both run fairly cool around 70c on the gauge. That's another thing Diagbox can help with since you can see exactly what the temperature sensor is saying & compare that to the gauge and to a spot-check of the engine with an IR temp gun to get an idea if there's anything amiss with fans/thermostat/temp sensor etc. It could be that the economy will improve as the car "learns" your driving style, since I believe they are an adaptive system, worth keeping an eye on.

Fingers crossed the issues (that weren't simply loose connections) were all simply a result of a confused BSI though and the reset will have cured them

cabin heating issue with my 407sw is caused by broken heater flap. heat on passenger side and not drivers or other way around. cheap fix if you do it yourself.
