This problem first occurred abot 18 months ago - visited Volvo garage -they cleared the diagnostic errors and no problem for another month or so - then recurred- same procedure - suggested battery needed replacement -this was carried out and shortly thereafter problem recurs- new Electronic Throttle Modulator fitted - in August last year - but problem recurs August this year and new Throttle Box again fitted - and that was only 2 weeks ago. Now the problem has re- emerged - for instance this morning start up 9.30 - "reduced engine power" script appears after a few miles and also the amber warning icon - but car performed well for 7 miles and then developed power loss -just made it, unevenly chugging along and currently parked outside office.I suspect it will behave well long enough to get me home tonight but I could be wrong!! Worrying and also when in this strange mode if for instance I have stopped at a pedestrian crossing I have to take the precaution of using both handbrake and foot brake - in this situation the footbrake requires more pressure than normal -thus the additional p[recautionary use of the handbrake.
Mileage is 37,000 miles

I do not have the fault codes immediatelt to hand as they are at home with my recent service sheet,
Hope this is reasonably informative.
Many thanks Mike I've always suspected something "physical" rather than just computer gremlins- I'll cancel my appt with Volvo garage and try a local entity,
ps would you still want me to send the fault codes?
