Hi I have a problem of "P0087 fuel rail pressure low", took the car to dealer who told me that fuel pump needed to be replace. but I am still driving the car 220km everyday, it gives me problem in the morning and specially on the uphill but then I stop the car and restart it after that I drive the car for 200km with no problem. please advice .. Reg

Answers

You may have an air leak in the fuel system. If you have a primer lever or button try priming the fuel system before you try the first start of the day. If the engine starts OK after priming you need to find the air leaks and fix them eg leaking pipes or gaskets or O rings on the filter or the pump.. Hugh from City of Glasgow

Answer this question

Michael Brophy, Australia

Citroen C4

My coolant alarm comes on and the fan runs at full speed just after I have started the car from cold and move off. This only happens intermittently. The first time it happened I checked the coolant level which seemed borderline low so I adjusted it to the recommended level. When the alarm goes off, switching off the motor for a few minutes and restarting 'fixes' the problem for up to a week before it goes off again. A Citroen dealer is 2 and 1/2 hours away. I have the car serviced at the recommended intervals by my local mechanic. Is the problem caused by the first alarm not being cleared in the engine management system or is it a coolant sensor problem, temperature or level? Any advice would be welcomed.

hellow. i cant open my boot and my remote can not wofk on a car ,what must i do ?

Answers

Mine did the same, turned out that the wires at the top (there covered by a black pipe) had come loose. If it isn't this then it will be the remote trigger inside or could even be that the lock just needs turning on the door so that it clips and releases when needed to be open. Hope it helps Laura from Yorkshire

Hi my anti pollution light has come on in my car, it has come on a while back but disappeared has anyone had this issue before?

Answers

Hi John I had the same problem anti pollution light on for a while then off again, eventually around 4 weeks ago the engine cooler started making a loud noise and didn't stop for about 3 minutes after engine was turned off. During this period the pollution light did not come on again. So happens the MOT was due and I also had a full service completed , the mechanic said they had done a small adjustment and since then coolant noise has stopped and no pollution light. Hope this has helped as I bought the car 12 months ago and had 12 months of not enjoying driving but since service so much better. Showroom gave me form saying it had a service but obviously not. 58 number plate Brian from Greater Manchester

Citroen C4

When the vehicles is at a normal temperature and you come to a halt and the revs are low the warning "stop engine oil pressure low". I've changed the oil and filter and changed the oil pressure switch but the warning still comes on. There does seem to be a oil leak on the timing belt side which may point to a crankshaft oil seal. This seems to be a common fault with citroen. If anybody has had this fault could you please help me.

Car has been running fine. I usually drive it by myself. On a couple of occasions however, with passenger on board, the seat belt warning lights have come on shortly after the start of a journey and the engine then acts like it wants to cut out. Was able to limp back home in 1st gear by over use of the clutch. I fear an expensive software/component replacement repair. Any help/advice would be appreciated.

Answers

John.. the phares auto inactive is the auto lights on system.... the clicking noise is probably the battery gone or may be starter motor issue.. however it could be that your alternator has not been charging the battery.. if the batt is 5yrs old or more its probably due a change.... if it jump starts from another good battery then it's your battery R Evans from Caerphilly
