So i fitted a blanking EGR plate to my 09 Focus 1.6tdci 109bhp with 65,000 miles and the engine light came on showing (P042F Blocked or stuck EGR Valve) and the car lost power so i removed the plate and bought a D900 OBD reader to reset the codes.
The engine light came on again after 3 or 4 miles so i removed the egr valve, and cleaned with Wynns egr cleaner then refitted and remove the engine code again. Anyhow the same P042f code keeps returning after after 4 or 5 miles.
Hi all, This is my first post so bear with me please!
My Zetec tdci with built in sat nav won't work but he radio works fine, when i select Nav from the menu it says "Your direction is not on a digitised map", and if i check the information button on the right it shows no GPS so i think its not picking up a signal?. I've replaced the antenna on the roof because i heard these can become faulty through water ingress and checked the cables at the back but to no avail?
My local Ford dealer said if there was a problem he would just send away the whole satnav for testing as they wouldn't know how to test it. Can anyone help.
Just one more thing, going into the SatNav at the back there's a black main connector with maybe 20 wires, a blue aerial plug and another black wire with a blue plug that fits beside the aerial with a sticker(C1791 4M5T-18812-LB), would anyone know what the wire with the sticker is for?
