HELP xantia TD electrical problems just got worse!!

[ecohouse1]

I posted last couple of days about losing my speedo and temp guage. They are still knackered. Drove back from work a few miles. Stopped for 30 mins. Went back out to crack on home. Put key in ignition and key symbol starts flashing and beeping. This has happened randomly over the last few years. Always OK on 2nd go. This time - no chance! Kept flashing and beeping. Try the other key I think. Luckily had it. First key wouldn't turn then when it did still beeping and flashing. Engine turns but no start. Good battery.

Disconnected battery for a minute. Reconnected. Still beeped. No start.

Are these all connected? All seems to be dash related.. Anyway had to abandon car to go back to tomorrow.

Seem to remember this on the forum before. Didn't have my non plip key but wonder if that would work?

Would be most grateful of any suggestions of where to start. It's like my car is haunted!!!!!!!

Is the car at all damp inside? That's what caused my 406 not to start. Left the doors open on one of those rare dry days, rest the BSI and it started. Left it standing for a few days and it wont start again, with the key displayed. I am assuming yours is an HDI.

Sounds like the transponder is not recognising the keys ( flashing key symbol usually means this) car will turnover but not start also suggests this. You'll need a Lexia on it to troubleshoot further. This could be a symptom of another problem so a diagnostic should be a priority.

I am a little out of my depth with this. I texted Chris morewood to ask if I could borrow his lexia. But notvsdure what to do next. Will I need the 4 digit security code for the car as I don't have that yet. I am wondering if I have some corrupted module somewhere in the dasdh or va bad earth as there seems to be a raft of problems in the same area. It's weird how it was totally out of the blue just after the car was running.
