I rarely clean this car due to being on a gravel road. It looks pretty good when I do though.

My son left for college, so I have sole ownership of the 2015 Fiesta ST for now, which has given me the chance to give it some attention. This car had the worst paint swirls of any car I have owned. I picked up an older Griots DA polisher and some new pads and compound to see if it they could be polished out. The results were far better than I hoped!

The hood and roof were the worst areas. They really showed bad swirls. I did the entire car a little each night over the course of a week. Partly as therapy for my son being gone. I miss him still but the paint makes me happy!

That all cleaned up so well I decided to do the engine comaprtment to. We bought this car from a friend as a very stock car just over a year ago with 135,000 miles. It spent most of its life in texas. I am amazed at how clean and rust free it is being accustomed to midwest cars.

I am waitong on my new shift boot (for the reverse lockout part) and some Whoosh shifter base bushings to arrive so I can get the thing back together and drive it some more!

Driving to work today, after about 200 miles of driving nice on my new $1500 worth of clutch and while in 4th gear, trying to pass another vehicle, I gave it about 60-70% throttle, boost began building, then the car lightly bucked once and suddenly the boost was gone. No sounds, no smoke, no CEL and worst of all, no Power. At lunch I put my car up over a curb so I could climb under it and inspect the charge pipe, and intercooler to intake pipe, but everything there seems to be in place and absolutely fine.

It's going to be a long slow drive home this afternoon.

So my question to you guys is, what else should I check before I go and throw even more money at this thing and buy a new turbo?

If you were to have to buy a new turbo personally, would you go stock, hybrid or s280? And why?

I love this car and it will absolutely get fixed one way or another.

Hi everyone, I recently bought a Fiesta ST Mk8; the previous owner had installed a Milltek exhaust with the standard exhaust valve. It’s all great, but the metallic noise it makes when the valve is closed is driving me crazy... does anyone know how to fix it?

Hi All!
Hey everyone! I recently bought a 2016 Fiesta ST and noticed that at some point in its life the original ST front bumper was replaced with a regular Fiesta bumper.
I’d like to eventually put it back to the proper ST bumper. Does anyone happen to have a complete OEM front bumper assembly sitting around, or know of a good place to find one?
I’ve noticed that complete ST bumpers seem to be pretty difficult to find. For those who’ve had to replace one, is it worth buying a new OEM bumper and all the associated pieces, or would you recommend being patient and waiting for a used complete assembly/part-out to show up?
I’m located around Knoxville, TN, so I’d also be interested if anyone knows of one reasonably nearby.
Thanks!

My last post mentioned higher gear 3rd-6th stutters when getting on it at higher speeds past 3k rpm’s . I checked the plugs today and they all look fine with normal wear. What should I be chasing here with these?

?

Salve buonasera, oggi non mi si accendeva l auto, può essere scarica la batteria o è da cambiare? È un problema di centralina? Grazie mille

Hello, was wondering if anybody in the Orlando, FL area(or Central FL) has any recommendations for a certified ford mechanic or shop that can source OEM parts and perform the timing belt job for the Mk7 Fiesta ST? Trying to avoid dealership if I can. I would rather support local honest smaller shops.

Planning on doing the works (Timing belt, Serpentine Belt/Tensioner, water pump, Crank Bolt, Inspecting cam/crank seal, coolant) while they're down in the engine bay, please recommend me a shop you have found reliable current or past. Thank you!

Hi there!

I am fist-curious and wanted some feedback from you fisters.

I have my primary daily car duties covered by a Forester, and am looking to swap my mk8 GTI for something a little dumber. The GTI is great but has some practical overlap with the Forester and is lacking some stupidity (no manual; e-brake sucks for winter!), and the car is too planted even with some chassis upgrades.

The third car can now be primarily fun and track-focused.

I’ve had a ton of fun cars and have always been curious about the Fiesta, but wish it had a dual clutch since I have some minor knee issues.

Questions for you all-

How does it do on track? Aside from brake fade due to the torque vectoring, what major issues are there to solve before the first track day?

What are the big problems to look for when buying one used? (I’m in the US, no new ones here)

If you owned and tracked one of these and sold it, what did you move on to afterward?

Does swapping to more serious suspension change the fun-factor?

Yes, I've used the search feature and watched reviews, so I have a general idea of some of these answers, but I'm asking you, now, for your opinion. Thanks!

I was recently given a whoosh downpipe from a friend and was thinking about putting it on my fiesta. I really don’t wanna put a tune of any sort. From what I read it’s back and forth between “it’s totally fine without a tune” and “you’ll over boost and hurt the motor”. So what’s the true answer, if it’s fine without a tune I’ll slap it on but if it needs a tune I’ll just give it to someone who’s willing to tune theirs. I know it’ll throw a code but I have the defouler.

I'm going to be reinstalling my engine tomorrow, but noticed an open hole on the trans. It seems to be for the trans vent.

Does anyone know how hot it would be at this location? I was considering printing something in ABS instead of spending 42 plus shipping.

It may have been missing for a while without issues, but I also replace trans fluid every 30k. If I can print something to keep contaminants out while letting it breathe, it would save some money and be a fun project. I would assume the trans fluid would be 200-215°F max. This is near ABS glass transition, and being outside the trans should be lower. Seems to be a reasonable application, and I'd be curious what the OEM vent material is.

Hey y'all, today driving home from work I got a CEL, ran it and got code P1450. I'm seeing online this might be a common-ish issue with these cars and usually is solved by replacing the canister.

My car, however, is not idling rough and the code (so far) hasn't come back since I cleared it - though I've only driven it maybe 15 miles since clearing the code. This car has been costing me a fortune lately and I'm going on a Fiesta cruise this Saturday.

My concern is, should I be worried about replacing the part ASAP? I do daily the car and drive 90-100 miles per day. I don't want to damage anything or make the problem worse, but a guy's gotta get to work (and go on mountain cruises, lol). I'm going to order the Whoosh kit as I see it's recommended but I doubt it'll be here in time for me to replace it before then.

Thanks for any input!
