I know that this has been covered elsewhere but my problem seems to be a bit different. The rear suspension on my C4GP goes down overnight. This only seems to happen when it is at the normal ride height. The only warning message I get is the 5mph one when I start the car. The compressor will kick in and inflate the suspension. The check engine light is part of every vehicle that has an electronic engine management system, either an integral one or only for fuel ignition. Its function is to alert the driver about any type of engine problems. While driving, the computer of your C4 (ECU o PCM) monitors air/fuel supply and exhaust gases in order to verify that the engine The central display now alternately reads " ESP/ASR System Faulty" and (less helpfully) "Engine Fault: Repair Needed". The car is driveable, but sounds like it is misfiring and won't go above 15mph. The car is driveable, but sounds like it is misfiring and won't go above 15mph. Having had the £450 door mirror replaced under extended warranty a couple of week ago, a new fault has developed. 60mph, the warning sounds and up flashes the Engine Fault notification, followed by the warning sound once more and the Emissions Control Fault notification comes up. The engine management light is on as is the Urea and Service lights. Joined: Aug 07 2006.

The ECU failing is rare as is the ride height sensor which can cause issues with the suspension not raising. Check the battery, if it is flat Citroens seem to give a ESP/ASR fault. Before starting the engine it ought to be 12.7 volts, if much lower it needs charging. Once running it should be about 14.4 volts, if not the alternator might be faulty unless you have a smart alternator which varies the voltage depending on demand but with the lights on Citroen UK have not yet identified whether the fault is hardware or software related, so it could be several weeks before there is a "fix". Citroen will surely have to issue a RECALL & should in the meantime ensure that owners of the affected cars are advised that their cars are unsafe to drive in their present condition. I added 10 litres of Ureau this evening but the light remains lit with the same message about the engine deactivating in 1500 miles. The car was serviced at 9288 miles at a Citroen dealer so I was surprised this was not topped up, as the manual suggests it should be, and I can't see any evidence of leaks (white snow colour residues apparently Vay Tiền Online Chuyển Khoản Ngay.
