Coil Light 52 Mondeo 2.0l Tdci Lx

[mrsyorkie]

Hello,

 

I'm new here and was wondering if someone could please help me?

 

Every now and then the coil light (not the engine management light) flashes and i lose all power in my car. I have to take the key out completely, then put it back in for the car to start again. When she starts up again she is fine, although she does sound a little rough for a few minutes.

 

We had this problem when we first bought the car and it was linked to the clutch (every time i put the clutch in there was a squealing noise and then the coil light would come on). After a struggle with the garage who put the car on a diagnostics machine and couldn't find anything wrong, and accused me of either a) making it up or ;) not knowing which light was flashing, they finally believed me about the clutch and replaced it.

 

Now though, i can't find anything wrong with the car yet the coil light comes on. It only comes on about an average of twice every few weeks, and it used to be when i was stuck in traffic or moving very slowly. Now though, it came on when i was doing 70mph on the motorway! The coil light will flash and then everything will cut out - complete loss of power, no power steering etc etc and it was a very frightening struggle to try and coast accross to the hardshoulder whilst avoiding cars and trucks in the other lanes. I only just made it to the hard shoulder. The car has had another diagnostics test and again nobody can find anything wrong!

 

Has this happened to anyone else and if so, how did you solve it? Please can someone help me because i'm really scared to drive my car now and i need my car to get to work!

What was the build date of your Mondeo? The 11th and 12th digits of the VIN number will tell you.

If it is between "1K" and "2J" the first of the TSBs (Technical Service Bulletins) below might apply. Hopefully it isn't because this will be expensive. ;)

Otherwise the other two are also possible candidates, but of course it might be none of these! At least it's something for the "garage" to go on. ;)

Incidentally, which garage are you using? It would be unusual for no fault codes to appear on a diagnostics test as the light usually illuminates when a fault is detected. A Ford main dealer will have the correct equipment to ensure the fault codes can be read. The equipment used by independent garages might not show any or all the codes.

Thank you Insider. I read that and my heart sank - it's build code 2B ;)

 

I took it to a ford dealer near me and they were so offhand with me it was unbelievable! They said that it isn't showing as a problem and the best time to do the diagnostics is straight away when the light flashes. How the hell am i going to do that? The light only flashes every so often and the car then cuts out. i then have to restart the car to go anywhere!

 

I'm praying it's not the first option - i had to have a fuel injector replaced when it began to leak and although the pipe itself only cost 20 quid, they charged me an extra 100 quid for labour!

 

It's got me puzzled though because if it was a real problem, surely it would happen all the time and not just every so often?

Mrsyorkie ...sorry to hear about your mishap on the motorway. What is happening is that your car is going into "limp home mode" when you lose power shortly after the glow plug light starts to flash, although I can't understand why you are losing power steering. Did the engine cut out altogether? A well known problem with the Mk 3 Mondeo is an injector failure and this can be diagnosed using the OBD2 test socket. What I suspect the garage is doing is doing the onboard test using the ODOMETER reset trick while turning the ignition on. This won't show up the types of fault code needed to diagnose any "hard latched" problems, only faults at the time of the test. If they do a correct fault diagnosis using the Ford Diagnostic System (FDS) kit then it will pick the problem up. I would take it to a Ford dealer. Beware though, if it is an injector you're looking at around Edited November 7, 2007 by Bleeno

Thank you for your reply Bleeno.

 

It was an injector pipe that was replaced and that was because diesel was leaking from it.

 

What I don't understand though is that if it was an injector failure, surely it would happen all the time?

 

When the coil light flashes the car cuts out completely, which scared the crap out of me when i was on the motorway!

 

I'll look to take it to another ford dealer next week, i've never liked my local ford dealer - their whole attitude stinks for some reason.

 

Thank you so much for your replies, you've all been very kind. I will let you know how i get on.

Not unusual amongst many dealers in the country!
