Question, my Volvo is getting to the point of being expensive.

Last week it went into "Reduced Power", stopped restarted and it was fine.

Garage diagnosed a split hose to the turbo, now my question is this, just poodling around town I assume, but don't know for sure, the turbo isn't used, so it should be OK to use, but on motorways, acceleration may put it in turbo mode, what do you guys think.

There is no "turbo mode", the turbo works all the time. How hard it's working will depend on how much gas is flowing through the exhaust which will depend on engine speed and throttle opening.

Driving around a bit with a split turbo hose wont do much harm in the short term.

If you mean the hose from turbo to inlet manifold, then it's probably fine to run around at low power for a bit. I had some work done on a turbo car, the garage forgot to tighten one of the clips so the hose blew off a few miles down the road when I floored it out of a turning onto a DC. Limp home mode until I found somewhere to pull over and found the disconnected hose. Reconnected and tightened and it was fine forever after.

Depending where the split is you may find it allows the engine to draw in unfiltered air, which might do a lot of damage if it's drawing in dirty air.

Two points , a turbo works all the time, it's not on a switch.

if the garage found the fault to be a vacuum pipe/intake pipe why on earth did you not get it replaced there and then?

In the grand scheme of things if you are worried your car is "costing too much" because of a rubber hose then maybe reassess how much your car expenses budget is..

Fix the fault.

Job done.

Anything else is stupid.

It's a Volvo S80 2002 and is classed as a classic for spares, hose would have had to come from Sweden, 6 weeks lead time, and having shelled out nearly 3k this year on repairs, it's time to let it go.

I have had it for 17 years now, but repairs are expensive and not sure what will go next.

Why on Earth don’t OPs tell us everything that’s relevant in the first post?

Scrap the car ASAP, buy whatever you want for whatever budget you have for a suitable car.

Didn’t think it was relevant to my original question. Thanks for all your comments.

Presumably you have a 2.4D? Do you know which boost hose is split? There are several.

If it's on a straight part of the pipe a bodge repair can be made using a chopped up coke/beer can and some hose clips. Fixed a friends Audi 80 on the way to Lemans like this and it lasted another few years until he sold the car!

Or pick up a good used one from a breaker?

Thank you for all your comments, as I said it's getting old and expensive, mpg is crap as well, 20 in town, VED 330 a year, had the car 17 years, 8000 miles when I got it as an ex demonstrator now 143,000 miles on the clock, getting expensive, and as a senior citizen every penny counts.

It's time to let it go, and get something with a lot less VED and around 40 mpg.

So I will poodle around town looking for a replacement, loads of car dealers around.

Then again lottery tomorrow.....

I think you should fix it (eBay for second hand part) providing nothing else major looks like it will break soon.

If you think 40mpg around town from a newer car you will find that tough for any petrol unless it’s like Aygo size.

I ran a 2003 Saab aero for 50k miles over 2 years. Averaged 38mpg and I didn’t used to hang around 70 plus 10%………

Sometimes work would provide me with a hirer car to go to the head office in Exeter from London. Always travelled late at night along A303. Usually astra 1.0-1.6 or similar. I would get around 42-45mpg unless it was a diesel. Same journey in my car taking the same time and it would get 38-40mpg.

Not much of an improvement IMO. Around town and short journeys maybe they will be better with warming up quicker etc but don’t just look at mpg unless you are going from something like a v12 Lambo to an Aygo.

I run a 17 year old Lexus IS300 Sportcross as a daily ( well, my other half does ). While not unreliable, as an older car it's into territory that I've not previously had to explore. This year it failed the MOT ( first time I've ever had that happen ). It needed a pair of front springs for the retest which it duly passed. Prior to that, a headlamp ballast. I replaced the tailgate this year because of corrosion.

My point being, it's possible to keep it going at justifiable expense, but you need to be a bit inventive, especially if you want to avoid Lexus ( or indeed I imagine Volvo ) main dealer prices.

I bought pattern springs new, recommended from someone on a Lexus forum for £106 the pair delivered. The ballast was a £50 ebay purchase, fitted at home in an hour. The Lexus part was just shy of a grand! I'm on good enough terms with the Lexus parts dept that he takes pity on me and gives me the oe part numbers so I can cross reference them with possible pattern replacements. Worth trying to do the same in your case I'd have thought?

With reference to your current issue specifically, my previous van split a boost hose in January, threw a fault code and went into limp mode. It always reset when stopped and restarted, but I couldn't get it fixed for a week, needed it, was working locally, and simply drove it " off boost " there and back in the interim period. New hose fitted 6 days later, no further issues with regard to that particular fault.
