Got myself a V70 2.5T SE

[4x4]

I've removed the charge pipe on the V70 several times over the past few weeks but I could never get the clamp at the top of the intake hose to sit properly and I didn't know why. Today I decided to remove the hose and try to find the problem. Once removed I saw the hose was past its best and decided to put it back together and was going to order another, also I never saw the cause for the clamp not to sit correctly but I did notice the charge pipe was an odd shape at the end, however as I'm not familiar with these items nothing I saw raised any concerns.



I visited my mate and mentioned the hose to him and he said he had an old one in his garage and after a coulpe of minutes appeared with a good used hose. When I returned home I decided to change the hose and that's when I discovered the problem...

The charge pipe has a metal sleeve that is there to prevent the clamp from crushing the pipe. With the engine hot the plastic pipe had expanded and the slight grip the pipe had on the metal sleeve let go and the sleeve fell off.



Careful heating with a hot air gun, a large socket strategically placed on the sleeve and a bit of brute force and the sleeve is back to where it should be and the oddly shaped end is once again straight.



Replacement hose put on and all stitched back together and sitting as it should

Creaky noisy V70 interior, not any more... 😁
A packet of Ikea stick on floor protectors strategically placed and a squirt of silicon spray on the centre arm rest hinges and all the creak and groans have gone silent.

We have a lot to thank Sweden for


And just in case that short hose above the turbo is damaged or ripped PFS supply the silicone DO88 kit for these which, apparently, give a sharper throttle response...if you wish to go that route.

I was confused seeing this and thinking how is the boost pipe deformed when it's aluminium.

Then I remembered the R is different. I have one of these to join stuff together which was a right pain to remove to get the pipe out the way for spark plug change.

Plastic pipe with metal sleeve inserts at each end, I watched a video on Youtube today where the mechanic removed the boost pipe and the sleeve was hanging out the same as mine, must me a common fault.

Lucky escape

Unfortunately the air-con recharge I had done on the V70 didn’t work. I stay less than 1 mile from the shop that did the recharge so it didn’t try it on the road home. I went out to the car later that day and turned the A/C on and the compressor kicked in, but the air into the car wasn’t getting cooler, I turned it off and on again and the cooling fan came on at full speed and wouldn’t stop. After connecting my diagnostics I had a pressure sensor fault showing, when I cleared the DTC the fan went off. I left it at that and tried again a few days later with the same results.

I decided to have a professional diagnose the problem and after speaking to the ‘expert air-con company’ at the top of the Google listing for my area and not feeling confident about the answers they gave me I booked the car into my local Volvo Indie thinking that at least they would know what they were doing. Well that was a mistake on my part, they don’t have recharging facilities and after connecting Vida and not finding any DTCs they decided it needed a new compressor as they could ‘see metal filings’ that had apparently been coming from my compressor. They then told me to buy a new compressor from eBay… I was shocked and furious when I heard this and it makes me wonder what sort of service they are providing to the Volvo community.

I decided at this point in time to seek out a proper old school specialist, a mate told me about Keep Kool in Cambuslang and I took the car to be diagnosed. Willie put the gauges on the car, started the engine and put the A/C on and off and told me that it really does need a compressor, but not because of fictional metal filings being expelled which there wasn’t, but because it wasn’t pressurising the system and the clutch assembly was falling apart.

Today it was back to Keep Kool where the V70 had some major surgery, Boost pipe off, top hose off, fan removed, serpentine belt off, power steering pump off, alternator off and eventually the air-con compressor removed.

The compressor motor is seized almost solid and I’m unable to turn it over, it must have taken huge amount of power from the car’s system to get it turning. Also the outside of the compressor is covered in UV dye and was leaking refrigerant gas.



The system was flushed and re-gassed and my air-con is working perfectly, the pressure switch didn’t require changing even though it was showing a fault.

Once home I decided to remove the clutch assembly, the centre which should be attached, it fell out onto the floor. The clutch assembly was in far worse condition than first expected and I doubt I would have got many more miles out of it before it fell apart leaving a horrendous mess.

re: the Ebay comment, was that because a) he thought he was doing you a favour really i.e. you could pay many hundreds but what's the point, you're better off just getting a decent used one or b) maybe even the dealers can't get them any more

for example with the throttle bodies the dealer wanted the old one back, to recondition using the casings which no-one moulds any more and then they sell you a 'new' one which is actually someone else's old one which has been rebuilt. in that case the better option genuinely is looking on ebay and getting someone to program it in for you

so that leaves me wondering where did you get the replacement parts in the end ? or did you repair the existing one somehow

[4x4]

I asked the price of a compressor and he sucked the air through his teeth and said "Oh they're expensive, better get one from eBay but don't but a second hand one" Not sure about your dealings with eBay but I have seen plenty fake parts, sub-standard parts, for sale there. He also told me to call my local Volvo dealer and ask for the part number which I already know they will not do. It just makes me wonder if they are repairing customers cars with cheap and cheerful eBay bought parts.

The garage I use for my MOTs which has been since 1986 (37 years) would never have told me to buy something from eBay and the only reason I didn't give them the work is they don't do air-con.

The old compressors don't get rebuilt, they go straight for scrap. New compressors are readily available, there are 3 main companies who make good quality ones, the rest are junk

[stuart bowes]

Fair enough, to be fair I've not had a problem with that part

but I buy literally all my parts off ebay, use VIDA or sweet talk the Volvo people into giving me a part no if I can't work it out (or find out with Scandix) then get straight on ebay and find a deal

I do avoid the cheap crap though obviously, probably half of it has been genuine blue-boxed volvo items and the rest is by Bosh, or Meyle, or whoever

and obviously the throttle body which was 2nd hand (professional rebuild with contactless sensor) but I don't usually do that

Lucky escape indeed! I imagine the previous owner didn't know how to switch off the air-con or just had it set to AUTO for all those years.

No doubt you should see an immediate improvement in fuel consumption. These dual VVT units have relatively good MPG, on the move, but don't leave them sitting and idling for long periods as that's when they tend to guzzle.
