Post by xcrs2000 »

Good morning everyone, sorry for my English. I am Carlos from Spain!

Here is my VIN: VF7**************[VIN obfuscated, can be read by forum staff], Citroen C5 (X7) 2.0 Hdi 16V FAP 138 CV automatico

When the engine is at low temperature, everything goes perfectly. When the temperature stabilizes, the idle is increased to 1000 rpm. I've looked at everything stated on the forum and I don't see any possible solution. Any suggestions?

Thanks in advance!

You need to plug it in and get trends off the fuel rail and MAF sensor and coolant temperature sensor. The car might think it's cold if the MAF which integrates an air temperature sensor into its circuitry or the coolant temperature sensor is reading incorrectly.
