Focus 2006 1.8 Tdci 'engine Systems Fault' Again!

02 March 2015 - 05:39 PM

Hi all,

This is a long one, please bear with me. A few weeks ago my sons friend kicked the GEM in the passenger footwell and disturbed a connector causing numerous problems. This I found and after taking the time to clean all the connector blocks (should not have done that) the car was fine except for the 'Engine Systems Fault' coming up and going off on the screen. I had this before and after chaging the fuel filter it went. This time though with a better scanner I get the fault 'Pressure Control Valve Malfunction'. Still I changed the filter and it got worse. Ran the live data on my scanner for the PCV and Fuel rail pressure and noticed that the rail pressure was going to 15 - 20k psi when the system fault was showing and dropping to 4.5k psi when the message went out. At the same time the PCV was running between 0 to 20%. Checked all the connections and the rubber seal in the filter, all ok. No air in the system. Still get the fault on the screen. So I think I'll check the Pressure Control valve. It's getting a healthy voltage at 12.5v engine off and 14.5v running on one wire and between 3.7 & 4.5 volts on what I suppose is the control wire. I have no scope so I cant get a waveform.

Then I restart the car and the system fault stays on permanently, the PCV shows a flat 15% on the live data with no response to differing fuel rail pressures. It is also almost impossible to start now.

Everything I've done seems to make it a little worse. I may be a complete idiot and have buggered something up I dont know, I'm only a hobby mecahnic and really wish I had points and distributors back but, alas it's not to be. Is the fault electrical or is the PCV at fault????

Your thoughts would be appreciated.



Bonnet Open, Erratic Rear Wiper And No Blower!

20 February 2015 - 09:47 AM

Hi all,

Just wondered if anyone has had anything similar to this before delving into the electrics.


Got into the car this morning and it said the bonnet was open. It wasn't. Then the rear wiper started going a third of it's usual sweep at each click of the relay. Then as the car misted up I realised I had no heater blower. The car was working perfectly when it was parked up but it had been raining heavily.  A fault or loads of WD 40 and wait for it to dry out?

Any help appreciated.




Oh yes and its a Focus 1.8 TDCI 2006. Might help!

Focus Vacuum Pump

17 November 2014 - 08:19 AM


My wife's Focus 1.8tdci 2003 has oil leaking from the union with the pipe on top of the vacuum pump. I have replaced the O ring but no change. I taped PTFE tape round the thread and the top of the pipe flange which solved it for a bit but now there's a leak again.


I am thinking of just getting a new pipe but was really wondering, if it's a vacuum pump should there be oil in there to leak out? Or is something internal in the pump shot and I need a new pump?



Rear Wheel Tracking

28 April 2014 - 03:32 PM

Hi all,

I recently had a 4 wheel track done on my wifes Mk 1 focus. Whilst looking at an exhaust problem I noticed that the camber adjuster bolts were rusted solid and dont look like they have moved since the car was built! I dont know how the toe is adjusted on the rear wheels though and dont know what to look for to check that it was done and I have'nt been mugged. :(

Can someone tell me what has to be adjusted so I can have a look please.



Handling / Steering Issue

03 April 2014 - 05:33 PM

Hi People,

I recently fitted a new steering rack to my wifes 1.8 TDCI Focus and it works a treat. Got the car 4 wheel aligned and it was as sharp as a new one. Wifes been driving it for the last 5 odd weeks and when I get in it to drive it the other day I noticed it felt really vague in a straight line or on changing direction.

Now when I changed the rack I checked the track rod ends and they were fine, wishbone ball joints were fine, replaced drop links, checked bushes etc., and all was fine. As I said the car handled like a new one. Tyre pressures are ok too.

The vagueness is only at speed, around 50mph plus, below that you dont really feel it, just a light feeling when driving straight. Over 50mph and changing direction feels like there is a slack bit at the point you actually change direction. Hitting bumps at this speed and you really have to keep correcting the wheel. There is no play at all in the rack when stationary. I checked it with a dial gauge on the road wheel and any movement of the steering wheel in either direction is instant.


Any ideas???????
