Hi all, first post so be gentle.

I'm hoping you may be able to help work out whats going on with my engine before having to take it in to my local garage and get charged an arm and a leg in labour for diagnosing.

Approx a month ago I noticed the engine management light show on my 2010 Volvo C30 T5 R-design, I plugged in my Fault Code reader to find it was stating:

P2178 - System Too Rich Off Idle (Bank 1)

I called my garage who said to clear the code and keep driving as it was a common fault and I shouldn't be worried but to phone back if it reappears. Approx a couple of days ago the light reappears and I plug the diagnostic in again and I now have 5 codes:

P2178 - System Too Rich Off Idle (Bank 1)

P0191 - Fuel Rail Pressure Sensor Circuit Range/Performance

P0089 - Fuel Pressure Regulator-Performance Problem

The oil temps are fine and it has plenty in as well as cooling fluid. There is no loss in performance not that I've been driving her fast after seeing this light come on.

Any thoughts would be appreciated.
