375bhp 2014 RS4
375bhp 2014 RS4
Had my car rolling roaded the other week and it made a paltry 375bhp!!
Would this suggest a massive carbon build up? Cars only done 46k though. Or could there be something else not right?

At the wheels or the fly?
Re: 375bhp 2014 RS4
I'm assuming it's at the fly going by what the operator told me! I'll have to check!

I had similar. Bought my 15 plate 2 years ago at just over 2 yrs old and 26K miles and down to 408bhp. Carbon clean at MRC and back to full number of horses

A 70bhp drop due to carbon, wow!
Is this due to lack of use or does it happen to them all? I see MRC want £800 for a basic clean and over a grand for the full monty?
Do you think this involves taking the heads off?

I doubt that loss in power would be down to carbon build up, more like another problem!
Never had my B7 Carbon Cleaned in 5years and that pulled like a train, same with my B8, nearly 5years and feels just as strong.

Re: 375bhp 2014 RS4
Is the carbon buildup in the B8 engine as much of an issue as with the B7? Should I be worried?

375BHP there's certainly something wrong, MRC is the answer

Sold Sept 2019. Now rocking an F80 M3
Re: 375bhp 2014 RS4
Car still pulls like a train even with only 375bhp, but yeah I'll be getting it down to MRC as soon as funds allow for them to give it a once over!! Hopefully it'll be an easy/cheap fix!! One can only hope!!
