First post, first V70 - Tell me its not a disaster
I've owned a Volvo before, a '64 B20 Amazon estate. I drove it from Orkney - Newcastle - Bergen to the Baltic and back. I could fix it in a campsite when the dynamo died. Twenty years on I've bought a V70, I fear my campsite skills are woefully outdated.
I bought a 55 plate V70 from a dealer on ebay, reassured that it came with a full year's MOT certificate. From the log book it would appear to be virtually a one owner car, possibly an ex demonstrator. it had a fully stamped service history, the last entry about twelve thousand miles ago, the current mileage is 157000. It fitted my needs as a painting and bicycle carrier. I paid a little over £2000 for it. I collected it from Colchester on Friday to drive it back to Fife. Immediately I was aware that the wishbone bushes were worn, I'd been warned about them and had budgeted for their replacement. I was miffed that they hadn't been picked up on the MOT. Midway home after refuelling I pulled back out on to the motorway slip road accelerating to avoid a truck. The engine management exclamation mark illuminated along with an engine management service warning on the dash. I deleted the warning and a hundred miles further on it happened again, this time it went into a semi limp home mode. Fortunately I was near a service station so pulled in. Stopping and restarting the engine seemed to cure the limp home mode, thankfully as I still had three hundred miles to get home. I avoided heavy accelerations and I made back in one piece. I've replaced the wishbones and ball joints and the steering is now pin sharp. The engine management issues might not be so straight forward. I visited my friendly garage and they read the codes with their machine. They were as follows. 135F Mass Air Flow Sensor - Faulty signal 1507 Turbo Control - Too low pressure E000 Control Module Signal Missing 580F Configuration Fault - Faulty signal 7700 Engine Control Module fault 1100 Outside Temp Sensor - Faulty signal 928C Cruise control - Faulty signal A02F Vehicle Speed Signal - Faulty signal 7600 Immobiliser Faulty Signal. An Impressive list I'm sure you'll agree. So, where to start? The turbo actuator seems to be working ok, there is some turbo boost, but as the code confirms it's too low. The garage has only ever worked on one other V70, they replaced a sensor on the air intake, it has the serial numbers 0261230106 and a Volvo number 30622083. I went to the local Volvo agent and they said that part had been superceded by 313554463. They quoted £93.60 plus vat for it. Would this help in my circumstance? Is there a cheaper source of sensors rather than the main agent. I also noted with the engine cover removed that an actuator at the front left (cambelt end) had side of the cylinder head was missing a link. The actuator was moving back and forth. I'm not sure what it relates to. I need to work out a strategy to isolate faults at the minimum of expense. I can live without knowing what the outside temperature is but I can't live with the limp home dark reaper. So that's my first requirement. Where do I start? EDIT - the cruise control worked, however the speedometer was slightly out compared to the sat nav speed. Thanks in advance, Peter |
A little over £2000 for a 55 plate V70 from a dealer sounds too cheap so some issues aren't a surprise.
All sorts of codes can build up over time so make sure they were cleared then get them done again to see more accurately where you're at then let us know because to be honest, the list of guesses at the moment might be more of a hindrance to solving your actual problem(s). Reliable used genuine MAFs can be had for less than £20 so don't pay dealer prices. |

My first call would be to the dealer. He is responsible for fixing these issues.

I will write to him but I doubt I will have any recourse. I bought the car fully aware there would be some issues. The bolted bits I'm happy with. The electronics are a step too far. We did clear the fault codes but found most returned after the resetting. The turbo boost one is the most critical, as it appeared to be the one which caused the limp mode. Peter |
Fix the swirl arm and make sure the oil level is 3/4 full and go from there. Cheapest place to start then get the codes read with proper volvo reader vida dice so you can actually see what's going on this may mean a trip to a dealer unfortunately but generic code readers are sometimes a hinderence on these cars! You can also purchase vida dice via eBay and if your owning it for the long term and sticking around the forum then it will
Pay you back many times over just like mine has! |

I had similar problems and took it to an indy. They were going to swap the MAF sensor but at my request did a smoke test. There was a big split in the intercooler.
Replaced that and it's been fine since. Not desperately cheap I'm afraid. it was around £600 from memory. |

I had another look at the missing swirl flap actuating arm. The ball on the motorised end is still in place. The ball at the cylinder head end is missing. There is still a hole there through which a bolt could be pushed. What length is the original linking arm? Is it straight or cranked? I might be able to make some sort of Heath Robinson link. If I can sort this out and at least see if it makes a difference I can eliminate it from the puzzle. |
