Ford Focus ST - Ford Focus St-3 advice - Popc9

Hi,

I was hoping for some advice. I found this car and hopefully going to look at it this week and test drive. Has anybody got any experience on owning one and what it's like? Mainly for the servicing and running costs for parts.

Thanks,

Jamie

I gather head gasket issues are prevalent if used hard..Check coolant for white scum.(oil)

More detailed information would be useful. Age etc ? Mileage?

It's a 7 year old diesel with an apparently low mileage which has had 9 owners.

The AT price guide also says the price is very low.

I'd be running a mile.

9 owners in 7 years should be a complete red flag - a "normal" car should have had 3 but allow for a pre-reg and someone changing their mind, say 5 absolute maximum.

Does not show reg no so MOT history check is impossible.

Usually the sign of shady seller and a car history full of issues.

I checked their website: all of the other cars have reg numbers displayed..

RUN AWAY.

A nine owner 7yr old diesel Focus ST? It’s a big no from me. Any car with so many owners has an ongoing fault that’s causing people to get shot of it.

If you want a Focus ST buy the petrol model, which uses a turbocharged version of Mazda’s L series motor. If looked after these can be very reliable but sadly many have remapped them and driven them hard which ruins longterm reliability and will invalidate insurance. It’s a chain driven turbocharged motor so it must have a full service record done using the correct oil. Good to drive, but 30mpg is normal unless you’ve a very light foot. There’s too much to go wrong with the diesels, as with any modern DPF equipped diesel at this age.

Do I also remember a version of the Focus ST with a Volvo 5 pot turbo? I’m guessing that was an earlier one.

Yup, that was the Mk II. Good car, bags of go and a dose of 5cyl character. Mostly ruined by lunatics messing with the engines and driving them through hedges. If 227bhp isn’t enough for a hot hatch on the road then there’s something wrong with you. It was bordering on too much power for a front wheel drive as it was. I tried to find a good one a number of years ago, before fast Ford tax took hold, but I couldn’t find a good one.

I thought there was - I spent many hours doing high speed passenger rides in one for a driving experience company but I’d lost track which engine it was.
Quick enough to keep customers entertained, but Recaro seats for a comfortable day…

Not sure about this so did a web search. It says on several sites its a 2 litre EcoBoost engine and one refers to it as an EcoBoom with the comment that failure would mean a rebuild with the opportunity to fit a forged bottom end, more boost and more power. The 2.3 turbo used in the Mustang is from the same family and is used in the Focus RS. No mention is made of any link to the Mazda L Series engine.

I know for a fact that the Mazda L Series morphed into the excellent Ford Duratec as used in modified form by Caterham (developed by Cosworth). The 310 bhp supercharged version was pretty much bomb proof even on the track.

Only reason I did not fit one in the Caterham was simple, the equally excellent 2 litre Zetec was way cheaper to buy, needed fewer expensive specialist parts to fit and for road use was more than adequate.

Ford badge their turbocharged petrol motors as Ecoboost, but they’re based on several different designs. The 1.0 is the one oft referred to as Ecoboom, there is also a 1.5 version of this in the later ST Fiesta. The Yamaha designed Zetec SE was also turbocharged in 1.6 and later 1.5 form and the 2.0 Mazda L series based Duratec was the base for turbocharged 2.0 in the Mk III Focus ST. They are all very different engines.

The 2 .0 ecoboost st3 engine is a derivative of the Mazda l engine . Worked ok in n/a focus and Mondeo, but troublesome in the St . Misfire and overheating due to poor thermal heat management in the engine block .

Can’t say I ever had any bother with them and the trade are all over them when they appear at auction. Serviced and looked after correctly and left in their already plentiful 247bhp original output they can prove an entertaining and reliable family hot hatch. I’d certainly have far more confidence in one than I would the diesels. Many are abused wrecks though so finding a good one will be a challenge.

Done a bit more digging and it seems that the early 2 litre Ecoboost used the Mazda L block but no other parts. Later versions used a different but weaker block.

From what I’ve read it simply says it’s based on the Mazda L series, but details are limited. Possibly where questions over reliability are coming from if later cars used a weaker block. The cars I sold are all early pre-facelift examples, which caused no grief for me. So much so that I’d quite fancy one myself if I could find a good one. Fast Ford tax is yet to really kick in with the Mk III, but nice Mk II’s with sensible miles are going for strong money.
