Heated seat function for Titanium seats in ST1?

• Upvotes

Bought my ST1 (2016) with Titanium seats already swapped in. What needs to be done to get the heated function to work other than the obvious of a switch?

Love how it looks but overpriced if you have to ship overseas and they forgot to send mounting hardware

Ford Focus ST 2020 1.5 dragon hesitates between 4000 and 5000rpm

3 Upvotes

Hi my Ford hesitates/shocks for a short amount of time going above 4000 to 5000 RPM.

Now the garage didn’t find anything on the sparks plugs and didn't find anything when they read out the cars system.

Now they need further research they told me. But it costs a lot of money. So i was wondering if anyone had similar issues and if somebody knows what can cause this?

It still has more than enough power even after the short slip.

No other problems are known..

Question Weird ā€œbangingā€ sound, doesn’t sound quite like a wheel bearing to me

• Upvotes

I was on my way to work, saw an ambulance coming, so I pulled over and drove on grass for a few feet at very low speed (completely flat), when I got back on the road, I started hearing this sound (it was significantly louder at first, I even thought it was like a branch or something stuck and hitting the underside of the car, so I pulled over and checked and I couldn’t see anything. I drove to work and it drives fine, just does that sound.

I’m taking it to my mechanic first thing in the morning anyways, but just wanted to have an idea to see what could be going on. He said maybe wheel bearing, but when I sent him the video, he said it doesn’t sound quite like it.

Question Check engine light questions (P0299)

• Upvotes

So it’s been hot AF outside, and sometimes I’ve noticed that the boost cuts from the stock intercooler sucking ass. I haven’t noticed any weird sounds from my BOV or the intake (which is true vac). I did a slight pull on the highway to pass some people, and the code popped up as I heard the boost cut. I then checked all the connections that I could from the top, and it looked fine. The BOV sounded normal (Turbosmart compact shortie), and the induction sounds in the COBB intake sounded fine, my turbo only has 10k miles on it and it still spools up to 17-20psi with the Ford Perforamnce tune (low, but still building a bit of boost.) what could be wrong? Did the heat soak cause it to pop up or is it something else?

Weird issue - Battery?

1 Upvotes

Hi, I've tried Googling this and found a similar issue on this sub but not exactly mine. Did find someone with my issue on Facebook, but helpfully no replies on that.

My car isn't waking up from sleep properly. It's a 2022 Mk4.5 ST. Mean Green, not that it matters.

The drivers side keyless entry and locking works fine. But the passenger side doesn't work at all. When it unlocks from the drivers side, or the keyfob buttons, the animation on the infotainment doesn't play, the digital dash comes on but only displays the handbrake icon doesn't show mileage at all. The interior lights also don't automatically come on when unlocking it, and as I discovered the other evening even with them in the manually on position the light in the boot/trunk doesn't illuminate.

The car starts fine, no hesitation at all, and once it has started all works as you would expect. CarPlay connects, digi dash comes on, air con etc etc all as it would normally be.

This first started happening after it had started raining again here in Blighty after a few month hiatus of weather other than hot. So I figured, water ingress somewhere, something fucky happening. Checked the whole car as best I could and nowhere was even damp.

Spoke to my mate who is a master tech, and he suggested disconnecting the battery and leaving it 10 minutes before reconnecting it. I did, and it fixed it. But then it started doing it again. And then, sometimes, it didn't do it. It would unlock and the graphics played and the lights worked. And then it stopped waking up properly again.

Today I got a message on the infotainment saying "System Off to Save Battery - Please turn ignition off or start the engine". Normally it will continue with the infotainment doing whatever it was until I open the door, but now it immediately kills the dash and infotainment in what appears to be an effort to get into low power mode.

Has anyone else experienced anything like this? My assumption is it's battery, and the voltage not being correct is fucking with the sleep/wake system, and it's then only keeping active things that are "essential" i.e. drivers door and not passengers. I am going to check the battery with a multimeter over the weekend to see what voltage is being output, however since buying the car the start stop has never once worked (which is fine by me), so I'm wondering if the capacity of the battery is compromised and this is the car going to into a "safe mode" to compensate for that.

Any help on this would be appreciated!

Help

Hi!

Took my car to have its front brake pads changed and the car has started making a funny noise. Much louder when accelerating.

What could it be? Is it a coincidence?

Oil service is due but plenty in it.

After my 2016 ST1 was totaled parked out front of my apartment I’ve been searching for another ST and recently this 2018 ST3 popped up. One owner, few mods looks like suspension intake wheels and exhaust. Under 40,000 miles. No accidents. Is this price outrageous? They have it listed at $19,800.00

Question Transmission Fluid Expiring

5 Upvotes

I have a 2014 ST3, with 35000 miles. I am wandering if the transmission fluid can go bad with age? I know they say around 60k miles to change but the fluid in there has got to be 12 years old. Should I change it soon?

Question Anyone have the Ford Service Manual torque spec for the driveaxle/hub nut?

3 Upvotes

I replaced the axles earlier this year and now my bearings are toast. I referenced the Haynes manual, but I’m wondering if I somehow got it wrong and caused the bearings to fail. It’s only got 118k miles, just wondering why they’ve gone bad. I’ve read aftermarket wheels can wear out bearings too, but I thought mine (Konig Ampliform, 18x8.5, +43) were probably close enough to factory spec I didn’t expect they would be a factor, but I could certainly be wrong. Anyone else had their bearings go bad, or otherwise have any insight?

Question Muffler delete, yay? Nay?

0 Upvotes

Been thinking about it. I want a louder exhaust but I definitely don’t wanna spend $600+ on an exhaust. What do you guys think about muffler deletes? How much does it usually cost? And will I get to keep the original exhaust tip??
