Would probably invalidate warranty. Been in there today to have it out with dealers. They're insistent that it's just carbon deposits and that an engine flush will sort it out and they're doing that tomorrow. Fingers crossed, for their sake!

Best one is, they say it just needs a flush but they've identified carbon build up in the forester behind the piston rings. Now I'm now expert but I thought the only way that could happen is if the piston rings weren't sealing, which would lead to loss of power, loss of compression and inefficient fuel burn which would lead to coking up? Or maybe I'm just being too suspicious?

The dealer manager is the one who told me the owner had picked his car up on Friday[emoji20]

Well, update on wife's XV. Phoned dealer they said that they hadn't even driven the car in the shop yet (dropped off on Saturday). Not sure what's going on but I'm clearly being told some fibs somewhere. They actually said on Saturday that the other forester was picked up by owner on Friday and he'd said it seemed fine, funny then that today I'm being told that they've just finished his forester this afternoon. Need to get to the bottom of this

Probably playing flight sims.

I got pulled up on the Stourbridge ring road for drifting around it at 3am when I was a young stupid boy racer, they pulled me over and sat me in the car for nearly an hour bagging on about how dangerous my driving was then said, "right we've no intention of booking you, what you did was wrong and we've !Removed! you up for the last hour by making out you're gonna get done for dangerous driving, but it's 4am now and we knock off at 5 and can't be bothered to do a load of paperwork because of silly sod like you, get in your car and drive home, I don't want a single wheel spin and if we see you being silly again you're booked" I had a 200bhp rear wheel drive manta and it was wet so I had to pretend the car wouldn't start so they'd go, if I'd have tried to pull away it would have spun the wheels, it just didn't matter how careful you were, good old live axle[emoji2]

But at least they're not on the phone and cutting you up. Well you'd hope not at least [emoji4]

Yeah and my dad drive it 40miles the next day to work before he phoned the garage. The stuff we did when we were kids eh? At least yours was ok. I launched my Opel manta once off a roundabout exit in Stafford, there's a steep downhill off it so you used to get a good 20-30ft flight but because it fell away you always had a soft landing, not sure what the cops would have said about it though [emoji3]

My brother hit a hump back bridge too fast and the car left the floor (significantly) being a family car it pitched up and landed heavily on its nose, he has to clip all the trim back on the bottom of the bumper, let's put it that way. It landed very heavy and he said it pulled to the left quite badly afterwards. My dad used to drive like Brian the snail too so he was pretty confused

My brother did that in my dad's company ford Scorpio about 10 yrs ago, he didn't tell my dad and my dad had to take the car back to the garage where he'd just had new shocks fitted, he ripped into then about the standard of their work. When he picked the car up they told him the shocks were fine but all the suspension arms were bent and that he should try slowing down. My brother didn't come clean for another 10yrs [emoji5]️

No nothing clean as a whistle and the DPF light hasn't even come on. Our neighbour is an Audi technician on their diesels and he says it's all a bit dodgy

Result is they will have the car for a few days to do an engine flush that takes a couple if hours, they're still saying it's just an engine flush. The other forester with similar problem was properly coked up, apparently even below the piston rings, which in my mind suggests that the piston rings couldn't be sealing if exhaust gasses are coking up below the rings. Me smelling a rat now[emoji15]

Not sure modern diesels would like that with the new DPFs they now have.

Agreed, I'm actually switching to nitro to use the cleanest highest grade fuel possible to protect the engine

Agreed, but the latest iteration of the Subaru diesel probably wouldn't survive the first tankful

Yep, Shell do Nitro+ now. It is definitely better diesel, but I'm currently testing whether worth the extra pennies, so far it looks like it is. I also get the feeling you can't run the new Euro5 engine on veggie oil, I think it'd due in a week, they don't even recommend using supermarket fuel

Run car to hull a couple if days ago on Shell Diesel Nitro, mpg went from 57 to 62ish, also noted additional low end torque and smoother acceleration so looks like it's well worth the extra 7p per litre for the XV. With the extra cleaning and engine protection will probably be a good decision. Overall it's not cheaper per 100miles, but looks about break even compared with standard diesel.

We reckon its piston rings there's a class action suit in the US over faulty rings. I spoke to out neighbour who's a tech for Audi and he says that, what we're being told is, and I quote "bo!!@cks" he says its a cover up for a known fault. The only thing affected by how you drive is the particulate filter.

Nope, nothing to do with DPF, you'd have warning lights if there was even a slight clogging of the DPF, they reckon its carbon build up in the valves. But I would have thought that carbon build up in the engine would cause a DPF problem. Our cars not even in the garage yet because we're waiting for the other forester to get sorted first. They did a flush on the engine but they completely dismantled the engine right down to removing the piston rings as part of the engine flush. Really? I'm not generally a conspiracy theorist, but I can't help feeling this is the same problem they had with the earlier Euro5 engine but would rather say its our driving style and that because they're a caring dealer they'll sort it for us. Since when do you take out the pistons for an engine flush? I've been in touch with them and it's going in tomorrow to get sorted. Will be with them most of next week, again I say a week for an engine flush?

Oh no, not take it over 3000 occasionally, we do that already, they're on about running over 3000 for sustained periods of time not a rapid acceleration. They're on about 5-10 mins constant once a week! The car had a problem from day one, was probe to stalling under 1300r so you'd go round a tight bend in say third, start to accelerate and it'd cough an stall, I think this is the same issue but they won't have it. Wife is starting to lean towards this being her first and last subaru

Its a Subaru XV diesel. I have one too but it runs much smoother and has more torque than hers with the "same" engine. I'm taking her car into dealership Saturday, they actually told her she needs to drive at 3000rpm more often, it has a light to tell you when to change gear and it flashes at 1700. 3000rpm in a diesel is giving it some beans

Subaru dealer have said my wife's car is broke because she doesn't rag it from time to time, which is cobblers. They've said that if driven with economy in mind then this can cause the problem, they've based this on 2 cars nationally that have this problem, so clearly my wife and this other person (incidentally at the same dealership) must be the ONLY 2 people in the uk that drive their diesel and get 50mpg everyone else doesn't have this problem because they don't drive that way, not sure I but that as an excuse. Also when doing a fluid flush is it usual to strip down the engine to its component parts, seems a bit overkill for an engine flush? Wondering if there's a hidden piston issue which warranted the change to nickel coated pistons that the 2014 car has, my wife's being a 2013 version, hers did burn some oil early on.

i'm driving up that bit of the M1 tomorrow :P Looks like they were all out to get you

works ok now, go figure

Nope, different error now
