'07 C30 Reduced Engine Performance but drives fine no errors

TheRealBen · Apr 25th, 2015, 22:08

Hi all,

New to this forum, so hello!

My 2007 C30 has been displaying the "Reduced Engine Performance" message, although I have not seen any reduction in engine performance, so to speak...

Ordered one of those ODB II readers from Ebay, but it hasn't actually found any error codes...

Read somewhere about unplugging the battery for a few mins to reset messages, but it still shows up!

At a bit of a loss as to what is causing it to display... Has anyone taken their car to a Volvo dealer for anything similar? Do they charge much for their diagnostic checks?

Thanks guys!

They'll likely charge you 30mins labour. Depending on the dealer expect about £45-ish from experience.

Could be the Throttle Position Sensor, common issue
