Please i need advice on how to go around this code on my car. I have 2006 Passat 2.0TFSI i bought as Toks not too long ago,but did not scan it prior to making the payment.The dashboard was clean with no code display,Engine sound cool and i only used a full tank (60L)+20L( toped up at Ihiala Anambra state) of fuel driving the car from Cotonu to Port Harcourt city ( Good fuel economy). My problem is i recently scanned the car and this code come up:
Catalyst System; Bank 1
P0420 - 002 - Efficiency Below Threshold - MIL ON
008801 - Boost Pressure Control Valve (N249)
P2261 - 008 - Mechanical Malfunction - Intermittent
I cleared the code and P2261 never came back, but P0420 still persist.
From the search i did online, it should be consuming fuel but am yet to notice that on highway drive.Not sure of City driving. 15L fuel last about 4 days driving within city ( tro and fro from work daily of about 2 hour both including heavy traffic).

My Question is:
1. Is the fuel consumption Ok?
2. Is there a way to solve the issue with the catalyst system?

Thanks Guys in advance

Please, while considering the above request, also take a look at this.

I own a Honda accord 2009 model. My battery got drained and I had to borrow another to start the car, then placed mine back while the engine was running (not jump starting). 
Two to three days later, the Vehicle Stability Assistance (VSA) and hand break light came up on the instrument cluster. The car is moving fine, no dragging issue, as it should be if the hand break was on. 
I have had d light cleared/Deleted but they came back on about 2hours later. 
Please, the good people and car experts here, what could be the problem and its implications, and should be my fear?
HELP!!!!!

Revert to your owners manual for fuel MPG. That would tell you what your car's fuel consumptionn rate should be both for city driving and highway driving.

As for your first fault error it means your catalytic converter located up stream is detoirating or has detoirated which ever the case may be. It needs to be replaced. I hope yours hasnt been stolen. Depending on the design of yours would be determine if the exhaust needs to be taken out or not for a visibility check

As for your second fault error. Boost pressure solenoid valve. That soleniod or sensor which ever yours is hardly spoils check connection. Could be unplugged. If spoilt replaces. This helps regulate air intake which inturns is used to actual fuel injection. You could have a case of misfire if bad or your car would stall as well . Location should be along vacuum hose that goes from your airfilter box into throttle body or located on the inlet manifold. Note- location might not be for your ride.

Never try what you just did. You would fry up your ecu that way by removing your battery while your car is running. If your vehicle stability assist( VSA) light was illuminated. Run a scan first and come back here and post fault error result. Then we take it up from there, if you are in lagos call 08165520837 or 08156087872. To get a free scan. Would end by tomorrow 4pm. Cheers

I had d car scanned, and it showed brake fluid switch problem. When d mechanic checked, he discovered that the break fluid was very low. He added break fluid and the VSA and hand brake warning light disappeared.
Thanks for your advice.

Fuel still coming up to 200# per litre . First thing you need to do is run a scan. A lot of component on car if bad can be responsible for high fuel consumption. How then do you know whats bad ? If you are in lagos call multi autolab for a free scan. Scan ends by monday 20th june 2016 by close of work (5pm)
