i have a volvo c70 2.0 turbo y reg 2001, its also an automatic. when in neutral it seems to stop revving at 4000RPM and seem to just have a limiter , even after 1 hour of running it wont budge past 4000RPM but when in D mode when moving power is there and there is no vibration or any banging noises smooth solid power right the way to redline should it stop at 4 grand RPM when in neautral ??? thnx for any replies. list of parts etm software upgrade and clean coil packs full volvo service mass air flow sensor no reports of anything from volvo diagnostics

Hi, This is in Drive and not neutral? Des. . . ;)

no its in neautral. when in neautral, rev and ti wnt go past 4000RPM but when moving i have full power no hesitation nothing so it sliek its got a problem when in neautral and ok when in drive

Hi, I believe that there is a limiter on the ECU to stop you revving beyond 4000rpm when in neutral.. You should be Ok when actually driving... A safety feature to prevent damage to the gearbox and engine... This may have been an ECU update (For the ETM maybe or some other upgrade)... Des. . . ;)

brilliant 

cheers thnx for that . lets hope thats all it is . car feels and seems fine was a bit worried

i'm having the exact same problem on a S70 T5 manual having just recently replaced a the electronic throttle module thingy and having the dealer program it is this safety feature of limiting the revs to 4000rpm true for manuals?

It's not a problem, it's what it is supposed to do! The turbo also won't boost whilst the car is parked up in neutral.

Which is a complete pain if you are looking for a boost leak.

???????????????????????????? What's the point of reving past 4,000 rpm in neutral, or even boosting in neutral? This is all you can achieve....
