Apologies for yet another decoke thread.

Car was booked in to Audi today to look at an intake manifold sensor not providing any reading. I asked them to look at the CB while they are at it. This is what they found. The car is a 2007 with 116000km. Does not look too bad. Audi reckon this should not really have any effect on performance. I asked them to clean it out while they have the IM off. I am awaiting the after pic. Your thoughts please? Can this 'little' CB have a +/-80bhp effect on performance?

As a side note regarding replacement of brakes all round. I was quoted (taking today's exchange rate into account) £2800.00 fitted. Is this on par with prices in the UK?
