ScottieDave Posted January 29, 2019 Share Posted January 29, 2019 Hi all. This is my first post. Great to be here. I have a Focus 1.6 diesel '08. I've had it in the garage twice in two weeks, but they can't help (still charged me of course). While I'm driving, the engine sort of coughs, as if I'm about to run out of fuel. I've took note every time it happens. It doesn't matter what speed, revs or if engine is hot or cold. For example, I drive 30 miles to work, and today going to work it done it 5 times, yet on my way home, it was absolutely fine. It doesn't matter if I'm on motorway or not. The only thing I have noticed, is it only happens when I've my foot on the accelerator. I don't want to keep putting car in garage, and being told the same things, so any help would be gratefully received (and I'll buy you a pint). Thanks. Scottie.

TomsFocus Posted January 29, 2019 Share Posted January 29, 2019 Is it roughly at the same mileage, say every 300 miles or so? If so, it's likely to be a DPF regen starting, if it doesn't complete it will keep starting until it can complete. Has the fuel filter been changed recently? If it's completely random and irregular then it sounds like you'll need to get done proper diagnostics on it, Forscan is ideal and there's plenty of info on it on this forum.

ScottieDave Posted January 29, 2019 Author Share Posted January 29, 2019 Hi Tom, it's completely random. If I didn't need it for work, I wouldn't drive it. I will look into Forscan. Is it a company? Quote Link to comment Share on other sites More sharing options...

It might give you a clue to the issues you're having 🙂 Quote Link to comment Share on other sites More sharing options...
ScottieDave Posted January 29, 2019 Author Share Posted January 29, 2019 Thanks guys. I've just ordered an ELM327 cable from eBay. When it was in the garage, the mechanic said he put it on diagnostic machine, and nothing wrong came up. It's really frustrating. I just worry it will completely conk out on motorway.

Their diagnostics won't show Ford specific fault codes, that's why we always recommend Forscan on here if generic scanners have failed. Has the fuel filter been changed recently? Also, I just assumed it was a 110 model with a DPF but reading back you didn't say, so could you confirm if that is the case or if it's the 90bhp model? 1 Quote Link to comment Share on other sites More sharing options...
Jarhead Posted January 30, 2019 Share Posted January 30, 2019 Hi, I had same cough and ignored it for a few weeks. Eventually it started to float around the revs whilst driving at constant speeds. Idle was also lumpy and loss of power. Turned out to be a wiring loom for the fuel sensor. Took six weeks to back order and replace. Wasn't overly costly to fix though at garage.

FatHead1979 Posted January 30, 2019 Share Posted January 30, 2019 +1 for what @TomsFocus said, modern diesels REALLY don't like tired/dirty fuel filters. Quote Link to comment Share on other sites More sharing options...

Someone really needs to make a sticky guide about Forscan and fuel filters to save us giving the same replies to every diesel thread lol. 1 Quote Link to comment Share on other sites More sharing options...
ScottieDave Posted January 30, 2019 Author Share Posted January 30, 2019 This will sound really thick, but, how do I find out if it's 90 or 110? It only says in log book, Focus Studio TDCI 1600. Quote Link to comment Share on other sites More sharing options...

It only says in log book, Focus Studio TDCI 1600. I would go on go compare or confused and put your reg in. Should come up with the power there. Or you could try Ford etis. Update: Ford etis! Just tried it and it works. Quote Link to comment Share on other sites More sharing options...
ScottieDave Posted January 30, 2019 Author Share Posted January 30, 2019 Finally, found it on Confused. It says it's a 90. Does this make a difference? Quote Link to comment Share on other sites More sharing options...

It means you haven't got a DPF! Welcome to the small exclusive club; you're the second member on here including myself that I know of 😁 Changing the fuel filter would be a good place to start.

ScottieDave Posted January 30, 2019 Author Share Posted January 30, 2019 OH, I feel important now. I've had to take the day off tomorrow as I don't think it'll make it to work. Hopefully can get it into garage without having to wait. I'd try it myself, but I know nothing about engines. 1 Quote Link to comment Share on other sites More sharing options...
ScottieDave Posted January 31, 2019 Author Share Posted January 31, 2019 In garage now. He told me had put a new fuel filter on a couple of weeks ago. He's going to take it for a run tomorrow (guaranteed it won't do it). Quote Link to comment Share on other sites More sharing options...

ScottieDave Posted February 1, 2019 Author Share Posted February 1, 2019 Hi. Just had call from garage. Said they had taken it for a good run, and it had done the same with them. They think it could be a broken wire leading to something in the engine, but electrical guy won't be in till Monday. 1 Quote Link to comment Share on other sites More sharing options...
ScottieDave Posted February 12, 2019 Author Share Posted February 12, 2019 Hello again guys. Just an update. I'm sad to say, my Focus has passed away to the great garage in the sky 😢. However, I've decided to persevere, and I'm off to see another one tomorrow. Is there anything I can look out for, to make sure I don't get ripped off again?

ScottieDave Posted February 12, 2019 Author Share Posted February 12, 2019 I'm going to have a look at a 08 1.8 TDCI Zetec, 155k miles Quote Link to comment Share on other sites More sharing options...

Personally I'd say budget for doing both belts unless there is paperwork explicitly showing both have been changed otherwise you risk things going bang without any warning (If its still got a chain then you don't need to worry as they pretty much last forever). Siemens supplied a crappy batch of injectors sometime in 2008 and they're prone to early failure (I'm not at home so can't access the Ford TSB confirming the date range of models affected). That said, the affected injectors usually fail at less than 60000 miles, some are reported to have failed at half this so I wouldn't worry too much about this point considering the car you're going to look at has done 155K miles. I've got the same engine in my early MK2 saloon, 158K miles and all the expensive bits are still original (turbo, clutch, DMF, injectors, high pressure fuel pump etc). I can 100% recommend blanking the EGR (10 minute job) it doesn't trigger an engine warning light on this engine and makes a nice little difference to how the engine runs, especially as lowish revs/throttle inputs. Mine's currently doing 54 MPG (measured brim to brim) doing 1 hours each way commutes to work (roughly 70% motorway 30% A/B roads, doing about 66 MPH on the motorway). Doing 72 MPH on the motorway drops it to about 50 MPG so not too shabby for an 05 plate shed 1 Quote Link to comment Share on other sites More sharing options...
FatHead1979 Posted February 13, 2019 Share Posted February 13, 2019 The important bit for the Focus from the TSB: TSB 27/2012 5/14/12 Excessive combustion noise and or hesitation during light load acceleration with the engine at high operating temperature Subject/Concern: Excessive combustion noise and or hesitation during light load acceleration with the engine at high operating temperature Model: Focus 2004.75 (07/2004–07/2011) - stage 4 emission level only Build Date: 07/2008-12/2009 So a 1st half of 08 plate should be okay but it's still better the check the build date to be sure.
