Computer of Citron C4 shut down

  • 2005 CITROEN C4
  • 60,000 MILES

My Citreon C4 2005 has 60000 miles on the clock, it would not start for me about 5 weeks ago, after several attempts with jump leads we got it started again, 2 weeks later the same thing happened me. On turning the key, the car engine is turning and then kicking out on me and will not start also I was getting messages on my screen saying anti intusuion alarm. I had my garage collect it, not a citreon dealer, the garage put the car on diagnostics and nothing is showing up. Initally I was told that the electrics of the car are gone haywire, now I am been told that the computer of the car may have shut down, my garage cant find the route of the problem so he today is bringing the car to a citreon dealer. Just checking with you regarding this happnening a 2005 year old car and in your opinion is this normal for the computer of the car to shut down.I had head gasket issues with this car about year and half ago and my garage done the neccessary work free of charge. Im been told that the price of a new computer for the car is approx 900euro plus labour. Im not even sure of the value of the car at this stage.

Thanking you in advance for your information.
Kind Regards,
Do you
have the same problem?

It is unsuaual for the age and mileage to have the ECU go bad. Check the terminal connectors for a tight fit and corrosion.
With the head gasket issues you have had, I would get a cylinder compression and maybe even a leak down test done. Sometime the timingbelt/chain can jump a tooth if there is excessive wear and teat. It sound slike your car had some bad luck with the head gasket.
You should also check the cooling system pressure. Check the oil for milky substance, (which is anti-freeze), and see if the exhause seems to smell sweet like anti-freeze or burnt like oil with a grey or white color to it.

There may be another issue rather than the computer.
Check the timing as this will tell you if the timing belt/chain/gers/pulleys and even crankshaft and camshaft postion snesors might be trowing the timing off enough to cause damaage.
