Hose kit

[macp]

Evening all

Had a spot of bother this morning.Car started normally but was idling very roughly then shortly after the dear old engine management light popped up.So I got the fault codes read and it came back as 414 which as you all probably know is "turbo boost pressure too high".They advised that they had found a perished hose which I assume feeds the turbo somehow and a valve was stuck open ??

Perhaps this was caused by a spirited drive home yesterday

Anyway fault has been cleared and the car is running fine again.Perhaps a good idea would be to replace all the essential hoses.Has anybody got any recommendations or sources of supply ?

Thanks all

I personally would identify exactly what caused the problem. Its quite rare the hoses just split expecially one that would cause a servere vacuum leak, perhaps there was undue pressure on the hose.

Most hose kits are around £70-£100 for a complete kit. Ebay is always a good start for samco and such alike.

I started thinking about replacing the hoses on mine yesterday, not really looked into it yet, but have come across these http://www.partsforvolvosonline.com/...oducts_id=3112

Seems a bit expensive though and don't know if its worth it, would be good to hear of peoples experiences.

Btw, sounds similar to what happend to mine, by valve, could they have meant the turbo actuator?

sounds like it was one of the small diameter vac hoses to/from the BCS (boost control solenoid). I'd replace them using internally braided fuel hose

The way I see it is if the standard hoses last for 10 years plus and are far cheaper than silicone hoses why buy the expensive ones? Most of my hoses were varieties of diameter of garden hose off the B&Q shelf.

That sounds like a good idea, i'll have to get some.

+1 Ill Second that, first thing I have done to every T5. Fuel line will outlive most cars. If you buy 5mm it will fit all the connections nice and snug.

Thanks guys I just assumed it was down to age same thing happened to my last T5.I think your right about the turbo actuator Liam.

Thanks good old pookie has also suggested this.

Just read up re the turbo actuator and the technician certainly didnt mention having to remove the turbo to get at the actuator if that is what the problem was. Im pretty certain he called it a "valve".

No problems this morning all sweet as a nut again but I will put this on my admittedly small joblist to be done asap.

Is this an S70R thing???? Mine very occasionally (although not for months now) throws a turbo actuator fault code. I just clear it and its never run any different even with the fault code. I've replaced my vac lines apart from the one to turbo (not nice weather to be under the car).

Cool how many hoses were there and how difficult a job was it ?

You have a nice S70R by the way.

I don't think you have to remove anything to get at the actauator.

I don't think you have to remove anything to get at the actauator.

You don't providing the heat shields aren't in place as they make it nearly impossible to adjust or remove.

As for running rough try replacing the vac hoses andcheack all the intercooler hoses to see if there is any leakage.
If he mentions a (valve) it will most certainly be the recirc valve there is a 4mm vac line running from it on the turbo to the inlet manifold.

That sounds right. It could well be me getting mixed up.

[macp]

Thanks guys I am grateful

Its not a serious problem but I like things right.

Thanks Pete

Im half and half about just giving it to the garage for them to get on with it or having a go myself.

Is the recirc valve also referred to as a dump valve ?

[t5 pete]

Its a very easy job to do the only one that is a little difficuly is the vac hose that leads to the compressor housing

You are best taking the heat shield off cos I don't think you'll route the line from the turbo to the bcs with it on.
1) line from turbo to bcs
2) from actuator to bcs
3) from bcs to air pipe just behind the maf.
4) from re-circ valve to inlet manifold.

Thats what I've/will do although I dont have a re-circ anymore because of the dump valve. A re-circ valve works basically the same as a dump valve I think, but a dump valve makes a noise

Someone will correct me if I'm wrong or I've missed any vac lines.
