Many thanks again.

Thanks for your reply. I am not using a Citroen main dealer. I don't know the name of the equipment being used - but certainly has some sophisticated equipment. (Will ask the question).

I purchased a C5 Exclusive, diesel, auto, estate a few months ago and immediately got a warning about the Airbag on the display at startup and at any other time that caused the diagnostic check - i.e. get out of the car. Then I started to get Deflating Tyres, then STOP Puncture. No puncture but I think the garage changed a valve. The garage tried all sorts and today had a new Comms200 (hope that's correct) unit fitted which appears to have fixed the airbag warning light but no get ESP / ASR warning message on the display and permanent bulb illuminated on dashboard. I never had this problem before. I have driven home about 25-30 miles and still no change. Any ideas?
