D5 - no power when kick down
Hey
So i noticed this really weird problem after a long 360 mile run out At about 310 miles and after a fillup of fuel ,the car goes into low power mode (not limp/no errors on dash) you try to kick down and theres just no power like there's a rabbit caught in my air intake. So, next day fire, up problem is gone and its driving like a beast. No issues for the next couple of days. last night it was a monster, really shifting well. I go to fill up with tesco diesel (i know i know) an add my ecomax additive. So today i fire her up go down the motorway and theres no power again. I was driving like miss daisy, so I didnt notice until i went uphill to overtake something and couldnt. If i squeeze the throttle i can get upto any speed i like but kick down and flaw it and the revs rise slower than normal and no power. 185bhp D5 07 400nm (or 20nm in this mode!) Any ideas? Its non permanent so it isnt the usual pipes leaking etc. and weird it happens twice after a refill of fuel. Last time i didnt have my additive so put in Shelll Vpower and this happened. L

Morning....
The notion that it is supermarket fuel is unfounded. There are six refineries that produce petrol in the UK and none of them are owned by Supermarkets..... it's the same stuff more or less that you get from a branded forecourt. First thing is to get is plugged in to some diagnostic equipment that understands Volvo - i.e. preferably Volvo VIDA at a dealer or Indie. There are a number of faults that can put the 185 D5 into a not well documented "restricted power" mode (rather than limp mode) and this doesn't put any lights or messages on the dashboard. The scenarios I have personally experienced are intermittent or complete failures of the DPF and Catalyst temperature sensors. In this mode the revs are limited to around 3k rpm, but under that it will drive okay so it's possible not to notice - even on an auto - if you are just pottering about.

Had exactly this issue with mine & simply removed the front bumper , struggled with the intercooler /radiator/ crossmember assembly ................. AND swapped the MAP sensor fitted to the top of the intercooler in the most ridiculous location since ever . The zero power issue was worst first thing in the morning & occurred whenever it felt like it ( buy genuine , as you will NOT want to perform the same task in two weeks time ! ) I was not getting any messages or warning lights , live data reading showed very strange values from the sensor .

Might be worth checking the little plastic arm that controls the swirl flaps, I had this problem and the arm was disconnected from one end, I also had fault codes for the MAP sensor but it could have been all down to that little bit of plastic! It's just under the engine cover to the front left looking from in front of the car, you'll probably see it hanging if it's disconnected.

I had the waste gate control valve malfunctioning on my car. Just barely made 90 km/h when towing an empty trailer. Slowed down even in a slight uphill.
