Another V10 FSI carbon clean

[richardracer]

Hi Andy,

Good luck, watching with interest. Manifold never taken off in my ownership from 60,000.

Regards

They have done 3 S8s and an S6 on my recommendation and as far as I know, all are happy - I know I was.

I am not connected to them other than use them on my cars, specifically the TT now

I was one of those S8s ! Couldn’t be happier, they really looked after me, completed the entire job and a couple of unexpected issues along the way. I would completely recommend VRS.

I've half succumbed and half been forced to do the full decoking and intake manifold flap removal work on my S8 over the last couple of weeks.



FSI = F*cking Stupid Idea

Do you have any equivalent pictures after the de-coke work / clean was done?

[Conquistador]

Unfortunately not, since the top of the engine and manifold was all removed to investigate a small oil leak, that's when the broken manifold flaps were discovered and I desperately tried to find a place that will do just the manifold work otherwise I would have taken the car to one of the previously mentioned places to get them to do the whole work.

Should have the car back this week so will immediately book it in with AMD Essex to get the carbon build up within the engine looked at (they do it in situ by hand). I'll ask them nicely if they can take some before/after pictures.

Ok thanks. I am interested to see the results with different cleaning methods and workshops. Here's my before and after

[Conquistador]

Just having the work done to gut the manifold has certainly improved the intake sound. Much deeper and throatier from in the car with the windows open or closed under any level of acceleration.

Next job is imminent, which is a decoke of the engine and a dyno/remap to tell the car how it should now be running, as well as tweaking to turn off the engine light which has come on due to the flaps being removed from the manifold, but that was expected.

I agree, the induction sound is slightly richer after the flap delete. I have also wired the exhaust flaps open on my stock exhaust which really add to the overall sound package.

Pleased you found a source for the decoke, not long now until she’ll be back to tip-top performance!

I was crawling underneath the rear bumper to tie the flaps open the next morning after I bought the car if there's one mod that S8 owners should be doing, it's this one. Had one pair of the centre silencers removed and replaced with straight pipe as well, which opens things up a bit more.

I can vouch for this mod, I had it done after seeing your report, what a difference it makes! Everyone says it's quite loud now, but I don't hear it in that luxurious cabin. It's great fun driving with the window down in places where I can hear it roar as it accelerates or that glorious cacophony of noise as blips and changes down under engine braking

I have just spoken to VRS and they now charge £1500 +VAT for this job which includes BMC filter, gaskets, carbon clean (by hand), remap and dyno afterwards. I didn't think it would be so much but I will still get it done in the coming months.
