I may have to sell the ST and buy two other cars. Anyone have any experience or knowledge of the Leon FR TDI 170? I am possibly looking at economy with a bit of welly.

Not really a lot to go on, i once had an hour to waste so took one out for a test drive, the cab was a nice place to be, and it was easy to drive, the cruise control was a nice gimmick for a change. The e-diff seemed to work a bit compared to the open diff on the ST, it was a wet day and they let me go out on my own
. And lets face it, in years to come their will be loads of spare/tuning parts from scrappers and tuning companies as it is a widely used chassis/engine.

I bought a new FR TDI in 2009 after owning the old shape from new, unknowingly to me it had the new particular filter on (EU rules) which if not taken on regular distance runs to get high running temperatures it does not burn off the build up of soot, so it gets blocked up which gives dash warning lights and eventually, if not taken on a long run, puts the engine in to limp mode if ignored.

It was the same dealer who I had bought my previous FR from and had known this problem but omitted telling me these facts when part x'ing although I had only done 15k in 3years so fairly obvious I was not doing many distant runs.
I eventually found I was being dictated to by the car on how and where to drive, as most of my driving is in the city the xmas lights on the dash kept lighting up so I would have to find a motorway for a run whether I liked it or not!

After lots of arguing the dealer agreed to exchange for a petrol FR, although slightly out of pocket I was much happier as drive was far smoother aswell. Morale of the story NO more diesels for me.

The modern diesel cars need to be driven on motorways usually. If not, the egr and the FAP will give you problems. And not cheap problems. I don´t like modern diesels for these reasons. A friend of mine has the Leon FR TDI 170 (the one with PD injectors, not the latest with Common Rail), and he drives it every day to work, wich is near his house. 5 kilometers or so. After 2 or 3 days, the warning light comes on in the dash, and he has to go to the motorway and give it some right foot, allowing the FAP to regenerate itself. Not good i think. Another known problem with this car is that the injectors can fail, and they are expensive to replace. Something around 2.500 euros for the whole injector set. Not good either. Apart the possible issues, the car is fast for a diesel, and has a lot of pull in all gears, but is noisy and far from smooth to drive. Also has a lot of grip and cornering hability, has a firm chassis. It´s a nice all rounded car, but not so confortable for the long trips, and a diesel car is suposed to be built for this.
If you like it, go for it, but i think there are better cars in the diesel market.

I had a Leon 140tdi reference sport before I got the ST. It was a nice car but not very reliable, the turbo blades were worn out at 40k miles and apparantly this is a common problem I was told by the turbo specialist who replaced it, cost about 1300 quid to replace.

The FR's had a lot of issues with injector problems, don't know if that has been sorted now.

Main thing for me was the boot is very small compared to the Focus too, one of the reasons I changed was I wouldn't have got all the baby stuff in it.

I struggled to get 40mpg out of mine too, usually high 30's.

yep - DPFs are a nightmare. DPF removal as part of the remapping process used to be fairly common place - not sure how well that would go down with the newer MOT rules though.

DPFs definately benefit from a good italian tune up though. On DPF fitted dervs you should notice that the engine will go through a DPF regeneration cycle. every so often the ECU makes the engine run hotter than normal and that burns all the carbon off the DPF, if it happens at night you will see a load of sparks coming out the back as the hot carbon is shot out.

of course you have to be on a longer journey for this process to be most effective.

there is a lot to be said for the modern petrol turbo motors, with small displacement stuff like Vauxhall's 1.6 turbo in the Corsa VXR pushing 200bhp but still capable of 40mpg, alfa do a 1.4 TB multiair motor with 170bhp and will do 50 odd mpg or the 1.75 cloverleaf motor will push 230bhp and still go 40mpg.

good strong petrol motors are out there and challenge well on efficiency, also remember petrol a good 8p a litre cheaper than derv atm!

All the more reasons that diesel engines should only be used if you're a frequent motorway traveller. There's no place for them in city journeys, buy a smaller petrol engine instead.

The instant one of those lovely extra components on a diesel fails (turbo, dpf, injectors, dmf, etc), you've just lost whatever you've saved in fuel plus a load more. I honestly don't see the point in buying a diesel unless you're doing 20K+ a year sat on the motorway.

My mate had a 55plate old shape 150 BHP one and had a tuning box on it, he regular got 50 mpg but he did have 40 mins drive to work on dual carriageway.
