Futher to my injector problem..here are the details. However, there's no black smoke at the moment.

52 plate V70 D5 auto - 99500 miles..cold start problem this AM for the first time. After about 3 mins of cranking, it started. Outside air temp around 7'C after a chilly night. Heater coil light worked as normal.

Volvo dealer quoted £250/injector plus labour.

So, taken the car to a local Volvo specialist. No fault codes showing, mechanics reckon it's an injector problem. They have quoted me £30/injector to have them checked + 1 hour labour (£52 +vat) to get them out and in. They can get any faulty injectors refurbished for £125 each with 1 yr guarantee. That sounds cheaper than Volvo!

Car is at the garage now. Should know more in the next few days. Will keep you posted.

If this works, I will give people the garage details for those that are interested. They have done work for me before and are very good. Garage is in Norfolk.

Default Update

Car is running sweet since the injector (x5) refurbishment and starts 1st turn even at sub zero temps. However, before the Injector problem, the computer was showing over 42mpg, but now it's showing 37.5mpg. Same sort of journeys.

Recently, I reset the computer before a long motorway run from Cornwall to Norfolk and filled the tank up to the brim. The computer showed 43.3mpg on arrival in Norfolk and I was cruising at err..cough...motorway speeds all the way. Exeter to Norwich via M5/M4/M25/M11/A11 in under 5 hrs..and I mean well under. The fuel guage was at 1/2 tank after 340 miles and the light came on after 540 miles.

However, since then the MPG shows 37.5mpg now with mixed Norfolk driving.

The car has just been serviced and they can't find any probs on the diagnostics but have replaced the fuel filter and checked the brakes, etc. New tyres have just been fitted and running at 36psi (225/45/17) Feels a little hard but I have a full boot area most of the time.

I am putting the increased fuel consumption down to the near freezing temps at the moment.

Your volvo dealer sells them individualy you will need the number from the top 1, 2 or 3 grade and tell them which cylinder and you get the pipe with it .

Hi

I believe you can buy them individually from Volvo nowadays. Or, just get the unserviceable ones refurbished for less. However, my reason for changing all 5 is that my guess is one of the others was likey to go wrong in the near future too and I need a reliable car.

I've heard of the same problem with the Mercedes 200 series ... a diesel recirculation valve if I recall correctly... meant to send the vapours through for a second burn. Don't know if it's the cause of your problem, just thought I'd throw it in.

Good luck,

Tony.
