Hello, I have a 62 plate DS3 1.6 VTI auto, the amber engine warning light came on so panicking I went to my nearest garage where they hooked it up to their code reader, it came up with Camshaft inlet dephaser, as the car has an extended warranty the garage recommended I take it to a Citroen dealer, my question is what the hell is a camshaft inlet dephaser and will it be covered under the warranty, any advice would be appreciated guys. Cheers.
