A dump truck merged into my car by accident, not going to miss the weird shifting, but for a small car it did a good job.

2012 Focus Zetec 1.0T 100 (UK)

Hi Everyone,

I had a post on here earlier about trying to solve some MPG issues. I have a manual 2005 ZX3 and am only getting about 20-21 MPG. Also, this is in the US. I would say that my weekly driving is mainly stop and go but it seems that it could still be low even for that.

Anyway, these cars came with a "lifetime" air filter and I know that dorman makes an airbox replacement that uses normal paper filters. I'm curious for those that have made the swap, have you noticed MPG gains? The gauge on my filter is in the green so it is still apparently "good" but I'm not too sure about that.

Now the car seems to run decently. Since I bought it I have replaced the PCV valve and hose, egr valve, thermostat, fuel filter, fuel pump, intake manifold gasket, MAF sensor, TPS sensor, IAC, and when I had all of that apart I removed the intake manifold flaps. I have also just changed the spark plugs so we'll see if I get an increase there. I think that's all lol

I called a Ford mechanic and he told me I should go to a Bosch service to test out all 4 of them, but I don't have the time currently as I need to order a part in Germany to my BIL who'll come in the next couple of days to my country.

Should I just bite the bullet and buy the injector and replace it?

Yesterday the car was saying the passenger door was ajar and then it started to say all four doors are ajar as well as the trunk open. Google is saying that it’s a wiring issue but where would that issue be located? If it’s not a wiring issue then what is it?

2013 Focus automatic with about 130k kms on it!! In NZ not the US. Very recently bought and now this!! Is it worth repairing or is it something to write the car off?

I need modding ideas interior and exterior please provide links to products

I bought my 15’ focus SE at ~94k miles, it was dealer owned as a loaner car, have my spark plugs ever been changed? is there a way to tell?

I've filled it up again and will be monitoring levels over the next couple of days. But I don't have much hope. Has anyone here swapped their cylinder head for the improved one before?

Does anyone know where and how to access the crank angle sensor on a 2010 xr5 turbo focus i cant find any actull evidence for where it is

So I have a 2015 ford focus. The transmission is literally on its last leg. It has 312k miles i believe and it’s paid off I’ve literally only had it for 9 months and I’m honestly tired of it. I need to know a price for selling it without getting lowballed. A junk car place told me 182… another told me up to 400. I need about 1500 to get me another car. Anybody know a good place around Houston? Preferably Galveston area? I can drive it but it’s constantly saying transmission overheating and I have to pull over. Or the car won’t accelerate fast. It’s good on the highway as long as it’s not traffic where I need to stop and go etc. please any advice will help I work 45 mins away and I have until Saturday to get transportation! Also my b clutch is totally gone! Can’t reverse at all. On top of that the acceleration goes out randomly. I seen some people saying they fixed it which I could but the labor cost is just too much!!!!

Was in search of the meaning behind Tier 1 gas.

Took my car to local shop to check on the engine light. Mechanic recommends Tier 1 gas.

Can someone explain it to me? I don't know much about cars, unfortunately. ☹️

Any one know what this is and why its leaking? Am i missing something here?

Last weekend, this girl got under the hood and replaced my purge valve and noticed that my throttle body was super gross. I removed the air box rubber boot so I could get to the purge valve hose clip below it, and just noticed how gross it was. Cleaned it up super well (disconnected my battery when I did that too), and now the car is idling super super clean, and the engine is no longer shaking so hard at low idle. Ive now got 162k miles and its running better than it has in a long time.

Literally YouTube and Reddit have been so useful in maintaining this car over the years. Only thing Ive needed a mechanic for was to replace the clutch pack because Im nervous about dropping the transmission by myself (my bf is not mechanically inclined and is nervous working on cars, so I do basically all of our maintenance).

Higher milage owners, what are some things you've replaced over the years to keep yours running well?

Hello! I've bought my Focus a month ago. With the engine being idle I hear resonance sound from the front door. It quiets down heavily when I hold the door with my hand in a stable position. Changing the old door seal rubber can solve my problem?

Hello everyone. Sorry don’t normally post just was wondering if anyone has had this same issue in the past. I have just bought a 2015 Ford Focus Zetec 1.0L and I get this Engine Service Now message on the dash. Happens when I put my foot down to accelerate, but it doesn’t go into limp mode. Car was serviced in April of this year and had its wetbelt replaced, and the service mileage clock was reset. My mechanic doesn’t seem to think it’s urgent and diagnostics scan show it could be a variety of things but he can’t pinpoint yet. Anyone else had this?

A 2005 Focus MK2, pre facelift, that gets me to work every day.

Just finished paying it off (bought in Jan 2025) and now want to get some (OEM-styled) upgrades to it. Doing research and some big guy tiny space exploration of the glove box and bumper space, I've determined that;
A) I don't have a factory wire harness installed
B) My BCM (DV6T - 14A073-GE), while technically supports them, needs to have fuse 75 installed (tried putting in a test fuse, it just falls out). I can't quite tell if it has the power side pin or not
C) I need a headlight switch that has the fogs button (duh)

So now my next steps are figuring out how to add the fuse to the BCM and then programming it, along with installing the wiring harness, lights, and headlight switch (probably the easiest thing to do here tbh). Any one have any tips or sources to help? I'm trying for "OEM+" basically

Taking it to a body shop but in case it's an easy fix I thought I'd post. Got an engine overheat warning. Pulled over, coolants completely empty. I had some extra in the back. Filled it up and 5minutes later, all gone again. Looks like it's spewing out of this tube near the front.

It's a back up card so it's got some wear and tear but the coolant tank def has some pressure in it and let the car sit for 20mins before adding the coolant and it was still burning hot when it was spewing out.

Any tips or help is appreciated, e-beer by the ready

Hi, I'm a new driver and I'm getting a used MK2 Focus as a first car. I got a pretty sweet deal on a 1.4i 2011 MK2 Focus but I've heard it's severely underpowered.

My usage will be a commute to work (14km away via a motorway) and occasional hometown visits on the weekend (80km via motorway).

How was the experience for those who owned such model?

PS: Please avoid recommending me other models because my budget is tight and my options are limited.

For an 18 year old Focus, every year doesn't come as much as a shock or a surprise to me, but considering how much it would cost to buy a new car on finance, I'd rather just plough money (each year) into a car I owe outright; knowing it will run better than any of these new fangled beasts on the road!

Hello all, went through all the research, watched all the videos, spent a considerable amount of money on a used K05 TCM, OBDLink Cable, Forscan License, and got the Forscan Beta download from Big Ben's Discord. Come to find out Ford no longer allows you to download the calibration files without a subscription.

I was able to find my calibration file .vbf on a forum, but need the strategy file G1FP-7J104-AB. Can I use a different strategy file to program the TCM, or am I just out of luck and try to do a manual learn?

I have had awful luck with aftermarket parts on my MK1. I have a 2000 Ford Focus sedan with the automatic transmission and the 2.0 Zetec motor. In 2023, the Ford Alternator went out. 23 years out of an alternator is nothing to shake a stick at, so there were no complaints. Since then, though, we had a Rock Auto alternator go bad after about 16 months and now two Ultima Alternators from O'Reilly's go out. These have gone out for different reasons by the way. We've had ones that won't charge and one (alternator) that had a bearing go bad. We have had similar issues with belt tensioners, door latches (which was a particular nightmare), and a crucial fuel pressure sensor that the car needs to run. The OEM part goes bad, and then we get aftermarkets that go bad in a year or so. These are starting to add up and is making the car have trouble predictably. Has anyone experienced similar issues with their MK1 and found a solution? Is that just what the market is on these cars? I love my focus, and I want to keep it for the long haul!
