Hi All, Getting the "Engine service required" message up on the DISP of recently required high mileage s60. Have read through some of the previous threads relating to this code but have a question. The car drives A1 with no loss of power etc which others seems to have experienced with this code.
I had the local garage plug the car in and 2 codes were logged; 1, ECM 6805 boost pressure control 2, permanent fault 1, 930a clutch position fault sensor (faulty signal permanent) Firstly , I assume these 2 codes are completley independent of each other, eg. if i get the clutch sensor replaced it's not going to remove the code for the boost control? secondly, from reading the previous threads on the ECM 6805 code it would appear that the Turbo Control Govenor is the most likley thing to throw this code? would this be the first port of call to replace? only it's £110 and i don't have any driving faults with the vehicle, but obviously don't want it to get worse and also want to get rid of the "engine service required" message! If anyone could advise me on the above, it'd be greatly appreciated. |

I haven't had the ECM fault but I know there's lots on here about it.
With the clutch sensor fault, I'm assuming your cruise control doesn't work. If not, a new position sensor will almost definitely sort that. They're £40 from a main dealer and can be fitted by you in 5 minutes. The two faults you have, won't be related unfortunately.

With the Engine Service required notification.... and limp home problem, there is a wealth of info on the D5 Engine section, but ....after going through all the suggestions ...including a new turbo input pipe, filter etc...
I finally tracked it down to an EGR fault, cleaned out the pipes from the EGR to the engine air intake and replaced the dump valve (which sits behind the big fat hosepipe at the front of the engine) Got a pair from scrapyard for 30 quid - all the same,but don't be tempted to fit the cheaper Skoda one - get a pirburg one for the volvo from the scrappers. I then bought a blanking plate with a smaller hole off E-bay for 3 quid and fitted it after cleaning the pipes out (again) Result - pulls like a train again ! started to trust it overtaking traffic.

They're a business and their job is to stay in business. It's a boost solenoid or VNT control valve and not all D5s have them. Which D5 version do you have?
