You could've done with finding what the fault codes was/are. I find it unlikely they would just go straight in and replace plugs and coils if the fault code linked to for example cam sensor. If the timing was wrong you'd expect a code for cam or crank sensor as its only these that control your ignition timing. I dont know these engines very well but you've not gave us enough information about the car such as year, fuel type.if it was my car I'd be getting the fault codes read and then make a decision whether to blame the garage or put it down to coincidence
EML LIGHT FOLLOWING CAM BELT CHANGE
Hi All,
Just had the timing belt replaced ( including pump and pulleys etc) on my sons Ford KA 1.2.
All seemed fine however the next day the EML light illuminated and the car started to run rough, pulled over switched the ignition off and re-started car ran ok.
However took it to the garage that fitted the timing belt, they put it on the diagnostic machine and informed me that the plugs required changing.
Replaced the plugs however the EML light came on again, garage advised coil pack required replacing to cut a long story short have replaced the coil pack and leads to no effect EML light still comes on intermittently.
Believe that the garage have either refitted the new belt incorrectly out of alignment ( strenuously denied by the garage ' our lads know what they are doing'), or having looked on other forums (FIAT it would seem that the phonic wheel sensors can cause trouble when the timing belts are replaced and need to 'relearn' the relative positions of the camshaft and crankshaft.
So before going into battle so to speak with the garage, the KA having a FIAT engine I believe will also have the same issue with the phonic wheel sensors needing to be relearnt?
regards,

Hi All,
Further information car is a 2013 1.2 petrol Zetec,
Car ran fine before going into the garage for the belt to be replaced.
Car returned to the garage with the fault, they connected it to a code reader (unsure which code number came up but was informed it was a misfire and the plugs require replacing).
Replaced plugs which made no difference garage then advised the coil pack required replacing which has been done again to no effect.
I don't believe in coincidence, at first I thought it most likely that the belt had been fitted out of position.
However looking on line especially on the Fiat forums (I believe the engine in the petrol Ka is a Fiat design same as the one used in the 500 and some other models?), as such a lot of owners have reported ELM problems after belt changes which in many cases was initially diagnosed as plugs/coils as a result of a misfire fault code.
It would seem however that the issue is due to crankshaft / camshaft sensors phonic sensors being disturbed, to remedy this the ECU needs to 're-learn' the relative positions which can only be done using diagnostic software with the right programme?

I have the exact same issue currently. Never had issues ever with misfire, eml light on , auto stop start light on and Amber warning triangle light on.
Took car to have a cambelt and water pump replaced. Now when i get the car up to speed between 50 and 70mph the light comes on, car misfires have to key off and back on again for it to clear. Took back the garage. Code reader pointed towards ignition coil pack. Part replaced and fault still present. I suspect timing not quite right, hope garage can re check..

Hi Hope you're well, i have exactly the same issue, did you get this sorted?

Hi, hope you're well. I have exactly the same problem on a car we've just bought our daughter, changed the cambelt, kit & water pump then limp home mode with warning lights when driven for about 66 miles (not very nice on the M25). If you could let me know if you got this resolved (hope you did), and appreciate anything you can tell me to help. Thanks,
Andrew

We are having this same issue with our daughters car. Did you manage to solve the issue - many thanks6 miles not 66 - sorry
We had the same problem after having timing belt, water pump and spark plugs changed on our 63 reg Ford Ka. We took back again to the garage after experiencing limp mode and they found a crack on the coil so replaced that and the spark plugs again. Still limp mode issues as cylinder 1 and 4 misfire and o2 sensor code. After researching the internet we discovered the phonic wheel reset, so attempted a manual reset, still limp mode. Getting to the end of our tether we took back to the garage and told them the history and about the phonic wheel reset....they had never heard of it and said they would have a look as possibly the replacement coil pack could be faulty. They spent many hours looking at it and finally decided to do a phonic wheel reset on the computer. They tried to that plugging it into the computer as a Ford Ka, but the options were limited in what they could do. They then decided to plug it in as a Fiat 500 as they are the same engine and a whole list of reset options were in front of them. They were then able to do the phonic reset, and now it runs perfectly with no limp issues. So take it back to whoever did the timing belt and get them to plug it in as a Fiat 500 and do the reset. Hope this helps as after researching this loads of people have similar problems where they throw loads of money at resolving the problem, and still experience the limp mode.
Many thanks for your help, we are going to give this a try, we use a mobile mechanic and he hasn’t got a computer, but he knows someone who does. Hopefully this works, it’s been a nightmare. Many thanks
My daughter travelled from Yorkshire back to Wales in the Ka with no further issues, after visiting us last week. Her journey up to Yorkshire prior to the reset resulted in 4 limp modes, obviously on smart motorways that's not good. The reset of the phonic wheel where it recalibrates the timing is only a Fiat thing but did the trick. We didn't get charged by our mechanic as he did the original timing belt change. He told us it seems to be a little known thing in the trade, but we didn't want to throw anymore money at the Ka and thought it was worth a shot after the research we had done on the internet. It is once again a trustworthy little car.Many thanks for your help, we are going to give this a try, we use a mobile mechanic and he hasn’t got a computer, but he knows someone who does.
