At this stage cannot remember, but believe in the first instance disconnected the battery and left for 30-60 minutes, reconnected battery and issue resolved. Note inthe vehicle histoty that had to reset P0602 code on the 16 May 2011, but unsure whether this was part of the problem we initially repor...

Vehicle ID YV1VS37691F667862. Engine No.: B4202273736, RHD, Australia, 50,000 kilometres (31,000 miles). Wife undertook normal morning start of engine, nothing happened, appeared ignition dead and flat battery suspected. I tried a few minutes later, same symptom, tried moving shift lever, no go, dep...

fields 100, whilst I agree with your methodology, also concur with your comment re scientific approach. Preference would be to connect a recording pressure/temperature sensor into the main oil gallery, as close as possible to the pump discharge. The unit should be capable of either downloading data ...

kcodyjr, thanks for feedback. As previously indicated, since new car has been on Mobil 1 and genuine Volvo oil filters, changed regularly at approx. 7.5K. Max oil change interval was some 8.5K due to Nullarbor crossing to East coast. Engine oil is sampled every second oil change and to date there ar...

Jeff (toolmanjsp), undertook the following works over the past couple of days relative to EVAP circuit and in an attempt to establish whether this circuit was contributing to the noise referred previously within this post. It must be stressed that these works were not as a result of any warning ligh...

Jeff, Further to my earlier correspondence, believe have worked it out. Location of solenoid valve is directly in front of trans dipstick and is referred as item 24, 9135444, valve. On the manifold side of this valve is what we believe you indicated as the check valve, referred as item 23, 1275794, ...

Jeff, many thanks for prompt reply. Could you please expand upon the location of the EVAP solenoid valve, believe it to be under the bonnet? Secondly, is the EVAP solenoid valve connected directly to the inlet manifold, or connected to "tree" block at rear and to left of engine when viewed...

Thanks for feedback, yes you may be on the right track with oil pump located at front of engine. This vehicle has been subjected to oil sampling (engine and trans) since new and there is nothing to suggest by way of elements in analysis results that would suggest an out of specification scenario. No...

Have the same symptons in 1986 850R, has been evident now for over twelve months. After replacement of water pump, timing belt and timing belt idlers and with serpentine belt off and therefore no P/S, A/C or alternator turning, noise was still evident. Therefore believe we can negate front end of en...
