C30 T5 Engine Management Light

[Metrix84]

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

P2178 - System Too Rich Off Idle (Bank 1)

P0191 - Fuel Rail Pressure Sensor Circuit Range/Performance

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.

Hi - try the VolvoTuning.net or Volvo C30 Crew UK Facebook pages, they're a knowledgeable bunch over there.

I got this - paid a loD of money for a garage to trace the fault.

This was on our 2004 V70 2.5T.

It was the fuel filter. Just in front of the right hand rear wheel arch. Corroded Union letting air in.

Cost you nothing to pop it off and get some wire wool on the spigots.

Thanks for this. I spoke with my mechanic who mentioned that it was either the fact that the fuel sensor was knackered or that it was reporting correctly and due to the age and condition it was running higher or lower than normal.

He said that he had a bad experience with this not too long ago and because of that he would not fix it and mentioned that I would have to go elsewhere if I wanted it fixing but I could be paying to fix something that is fine (or not fine)

So it's left me in a bit of a conundrum as to what to do next. A friend had mentioned to send it to Volvo but I suspect they would charge me around the cost of one of my kidneys.
