#505481 Is There A Headlight On Alarm

Posted by mjt on 23 July 2015 - 05:28 PM

On our 2003-plate the lighting switch has a parking light position anticlockwise from off. You have to push the knob in slightly to select it. This puts the side and tail lights on without the number plate lights and doesn't activate the chime. It's quite easy to turn the control past OFF to this position if you're not aware of it and you happen to be applying enough pressure to the knob. Maybe that's what caught Malcolm's wife out. It definitely chimes in the normal sidelight position.

#504023 Very Bad Cold Starting And A Lot Of Grey/blue Smoke

Posted by mjt on 19 July 2015 - 10:53 AM

The light won't give any indication of the state of the glowplugs. You need to disconnect the wiring and do a resistance check. I replaced the plugs in our 1.8TDCi, similar age to yours and done about 89,000 miles at the time. When I tested the plugs I took out three were open-circuit and the fourth was high-resistance.


The glowplug light on ours goes out in under a second, summer or winter, but I found by connecting a lamp across the supply they actually stay on for about 5 seconds. I have read that in really cold conditions they may stay on for a while longer after the engine is started to help warm-up but I haven't tested this.


It does sound as if yours might be getting air in the system when it stands overnight.

The windows don't shut when locked.


If global closing is enabled it should work by holding down the lock button on the remote for a few seconds. Have you tried that?

As the oil capacity of the engine is 4.25 litres that means it must have virtually run dry of oil which poses the question of how you came to let it get in that state? Unless you have a catastrophic oil leak or it's burning vast quantities you shouldn't have lost 4 litres in a normal service interval. How long since it was serviced? Have you ever checked the dipstick?


If it really needed that quantity of oil it's pretty well certain you've trashed the engine.

#492819 Installing Drl's..

Posted by mjt on 05 June 2015 - 01:14 PM

I MUST understand how it works!!! lol :D

I agree with you Darren. As an electronics engineer I have very firm views on what is, or is not, good practice and I want to know how this works. If it is, indeed, detecting a voltage change at the battery I imagine this has been done to simplify installation but personally I wouldn't choose to design something that way.

#492801 Installing Drl's..

Posted by mjt on 05 June 2015 - 10:55 AM

Mine is connected to the battery and come one when I start the car. I think it's to do with the relay and the drop in voltage when you start the car.

If it works connected that way it must be detecting the rise in battery voltage when the alternator starts charging.  If so that seems a bit 'iffy' to me though. Personally I'd want it sourced from an ignition-controlled circuit.

#483626 2004 Mk1 Focus Intermittent Speedo Fault But Not Vss

Posted by mjt on 08 May 2015 - 08:59 AM

We had the same problem on our 03 1.8Tdci estate when we first bought it. The vss and cluster were both changed but didn't cure it. It was eventually found to be the loom chafing against the gear linkage. Has been fine since (7 years).

#482617 Ford Focus/ Mondeo Horn Again

Posted by mjt on 04 May 2015 - 11:00 PM

Hi Dave,

No the position of the relay won't make any difference - the overall run length of the wire, battery via relay to horn, will be much the same. The fact you're using thicker than stock and probably a more direct route, hence shorter run, should give an improvement.


I don't know the Mondy body. If the bracket you're referring to is welded to the chassis and you're sure you've got a good clean connection to it then running the new ground wire from it ought to be all that's required. If the bracket is bolted to the chassis you'd need to make sure the electrical contact between the two isn't being degraded by corrosion.


If you're happy with the electrical connections but are still getting poor results the only recourse, really, is to do some voltage checking with the horn operating. Check the voltage across the horn spade terminals if you can get probes onto them and see how much, if any, voltage you're losing. If more than, say, 0.5V then check between the horn ground spade and battery negative terminal and between the horn +ve spade and battery +ve to see if you can pin down where the voltage is being lost.

Posted by mjt on 04 May 2015 - 08:19 PM

If I've understood this correctly you've installed a relay near the horns, run a heavy wire to it directly from the battery (fused I hope) and used the stock wiring to operate the relay. If that hasn't improved things I think you'd be right in suspecting it's an earthing issue. If you can stand the racket you could try measuring the voltage between the horn earth point and the battery earth while the horn is operating. Alternatively why not try running a heavy gauge wire between the two earth points.

#473241 Focus Focus 2.0 2006 - Radio Antenna

Posted by mjt on 05 April 2015 - 09:50 AM

I may be wrong but I think the antenna length is set to a specific fraction of a wavelength so it is effectively tuned to a small range of frequencies. If you just crop off an arbitrary amount you destroy this tuning. If you live in a strong signal area you probably won't notice it but it's effective range could be compromised.

#470897 1600 Tdci Engine Cutting Out

Posted by mjt on 29 March 2015 - 09:43 AM

What have you used to read the codes? When our 1.8Tdci did this it turned out to be the cam sensor, but that threw up a code that was readable on the garage's diagnostic equipment.

#468647 Strange Oil Dipstick Reading

Posted by mjt on 23 March 2015 - 10:12 AM

Took it for a run and did about 15 miles then got home and turned engine off for an hour . Went back to check oil and upon pulling out the dipstick there was no oil on it! Put it in again and gave a normal reading !!!

Jon, this seems to be normal, mine does the same (1.8HE petrol). I have a theory that the o-ring on the dipstick forms an airtight seal that pressurises the dipstick tube, preventing the oil moving up it - until you remove the dipstick and release the pressure.

The information that is wrong does not affect using them. I just pointed that out to warn that sellers can make exaggerated and/or downright incorrect claims about their products and it's best to treat them with a modicum of circumspection :)

#465591 Engine Revs Hang Between Gears

Posted by mjt on 15 March 2015 - 09:00 AM

Yes, those K-series engines were very prone to HGF, especially the early ones with plastic dowels between head and block. Beyond 50K miles it was almost guaranteed. Not the best design of engine, Rover (and Land Rover) struggled to find a gasket design that would last.

#463172 Which Is The Better 1.6Tdci 2.0Tdci Engine

Posted by mjt on 09 March 2015 - 04:39 PM

I think someone had lost the plot a a bit when it came to the Mk2-2.5


I agree Darren. Compared to our old Mk1.5 I regard my Mk2.5 as a bit of a design disaster. I reckon they must have given it to some work experience kid! :rolleyes:
