I have fitted my new arm, just hoping it lasts a while, my only concern is if the hole i drilled will start to open up after a while with all the pulling on it.

It is important that the arm has full travel as the end stop positions are memorised by the ecu and if the arm's full stroke is restricted you will get the limp mode and fault code ... also the air flow through the system is carefully monitored so if the flaps dont shut completly again you will get the code and limp mode . However if the flaps fail in the open position the system will not notice it .

Yes, it is important the "bump stop" allows full movement of the arm, and just takes the strain off the mechanism at the end of the travel.
Mine has been OK now for over 16K miles, except for one hot day when the glue gave up on the plastic buffer and allowed the mechanism to overdrive - something that happens every fifth engine switch off, and the cause of the whole swirl arm problem, IMO. I was especially pleased it worked on my engine as the part of the mechanism in the engine is now so knackered that the arm drops out far too easily. To date, the bump stop alone has worked, with no other mod.s |

Hi,
Does Anyone try to remove the flaps or the hole axel where the flaps are mounted? Would it mix up the airflow-sensor if they are removed? Are the flaps so big that they can't go trought the intake tube, like on the BMW motors? |

Swirl valve? more like money swirling down the drain!
All,
Just for info. I have just had the Swirl valves changed on my 55' S60. I have had a good read on the forums of people being surprised by the prices quoted to do the change out from both dealers and independants. I have to say... IT WILL COST!!! Dont take the cheapest option, find out what work they will do EXACTLY! So far for me, Swirl valve assembly £81 (cost) 2 hours labour £100 £181 is cheap i hear you cry. Cost of the seals going on the injectors and spraying diesel around my engine bay because the mechanic thought he could save me some money.... The car is back in the garage (1 week ago) waiting on new single use fuel pipes (6 off), single use injector seals and specialist volvo tools. I have yet to hear the price for these parts, but rest assured, I will not be paying the labour since it should have been done in the first place. Also, If anyone needs the plastic arm, I have one spare now. PM me. (it was one clip on the cup that gave up) |
