Focus ST-2 Mk3 2013 Revs bouncing

So, I went a lengthy drive to Blackpool yesterday (around 300 miles round trip) and car was absolutely fine up until driving through Manchester after coming off the motorway. When stopping at lights I found the revs to be bouncing, it would drop below idle, to around 500rpm and then bounce back to 1300/1400rpm, do so a couple more times and then settle, it then continued to do this at every stop until we parked up.  It stalled on 1 occasion through dropping way too low that it couldn't recover but started straight back up no fuss.  Yet didn't do it on the return trip.  Car is still running fine and having only owned it a couple weeks is still under warranty from the garage so taking it in tonight.  Basically I would appreciate if someone else who's had this experience know how it got fixed so I can tell the garage so I can get back on the road quicker with it as I'm not particularly looking forward to driving a Nissan Micra courtesy :tongue:.  Just hoping to speed up the process.

 

I've read online that there was a recall when it was new for a similar sounding issue but I don't know if this particular one was ever sent back, or if it is the exact same issue

 

Thanks in advance

Could be a sticking throttle body.

A bit of lubrication and a spray can of cleaner may be the answer.

There were only recalls in the US. There is a TSB for this though.

It's a bad connection on one of the wiring looms. Get it back to the dealer and they should be able to sort it.

Would you be able to point me in the direction to get this TSB? I've found TSB for everything but this problem, I called Ford and they didn't want to know, hopefully if I can get the TSB to the garage where I purchased it they should be able to fix it for me.

Only Ford can see the TSB.

Your dealer should be able to look for it on their system.

Don't both calling Ford CRC, they are useless.

It was my local Ford dealer that I called, all they wanted to do was charge me £96 for a road test to see if they can reproduce the problem, but they openly said they wouldn't take it on a long enough drive that was necessary to reproduce it!?  So now I'm lost of what to do.  I fear if a call them back up and ask them to look into a TSB for it they will play dumb, seemed he couldn't wait to get off the phone.

I assume you are out of warranty then?

Tell them you have read of a known issue for a manufacturing defect on one of the engine wiring looms which can cause the issue.

I'd recommend speaking to the service manager, sometimes it is better to do it face to face too.

You may have to commit to paying for them to look, but only if it turns out to be an issue other than the manufacturing defect which there is a TSB for.

You need the dtcs checked to see if there are any stored if ford garage dont want to know, thats the starting point, then go from there.

Yep out of warranty in Feb, just missed out.  Though the garage I got it from will probably cover the costs if there are any as I got 3 month from them

I did say about it being a known issue and he just pleaded ignorance saying you can't trust online forums as only the people with the problems post there. Surely if there's a number of people posting about the same problem it's trustworthy info! haha.  I'll be having a trip to them at the weekend hopefully so I can speak to someone face to face

You get minimum 6 months "warranty" with a used car, covered by SOGA.

Car is not of satisfactory quality, should last a reasonable amount of time, etc.

Get it back to them and say you want it sorted

The problem is that copyright exists on these bulletins. To reprint them on forums in this country is illegal and thats where the manufacturers hide.

You might get help from an independent garage that specialises in repairing Fords as they are usually run by Ford techs who have left for some reason.

Bear in mind that a TSB is only a technical service bulletin (basically an advice memo), not a mandated repair or warranty order.

Unless you have an extended warranty, it won't be covered anyway.

It's only purpose is to help the techs when it comes to attempting to solve a problem with certain symptoms.

This is something you are probably going to have to pay to fix yourself unless you have an extended warranty with the dealer you bought the car from.

I still say carb or throttle cleaner but don't try oiling or greasing anything around the butterfly valve as this can cause more hassle by attracting crud.

Either way, if the OP has only had the car 4 months, then they are entitled to a repair under SOGA.

and either way again it needs looking at to determine the fault, wiring harness check only relevent with a certain dtc showing.


apparently.
