Decarbonisation for GTI Mk6 at 2 year service?

[The_Hawk]

Be interesting to hear what they *actually* do.

Things like the "injector clean" are usually done on the car without pulling anything out. Sure if they are removed an ultrasonically cleaned it can be good... but it's not usually what happens. I'd guess this falls into that same box.

Personally, I've always been a fan of the M1 decoke.

Take a nice long drive down the M1...

Doesnt do anything

Any of the decarbonising services need to be done every 5k km or they dont work well, all they do is take off the layer of oil that hasnt baked itself onto the intake dividers/valves. The only real fix is to remove intake and clean it by hand!

Is this the same as the upper engine cleaner that Subaru use as part of every scheduled service? It costs around $17 and comes out of a can.

Rort IMHO I had this offered to me by the dealer regularly some years ago when I bought a new MkIV. Never took up their offer and never regretted it. If its not recommended by VW its not necessary.

why do people buy expensive (relatively) cars and be the most stingiest after at everything else is beyond me...

Yeh, I can't get either.

If you have ever actually taken it apart to do it properly, you will no doubt see just how little even a specific spray clean would do, but hey, better than nothing. Do it yourself by getting the Subaru cleaner, just remember not to pump it in, especially in a diesel, will make the engine rev somewhat!!

+1 BUT...

There is a difference, IMHO, between spending on something that works and is worthwhile and spending on something that is a rip-off. Not that I am saying what was offered the OP is a rip-off, but if it is something like the Subaru spray, for the price quoted, that is, indeed, a rip-off. If it is, on the other hand, removal of the intake manifold and a clean of the valves, that's a completely different story....

After-all, why do many of us avoid stealerships and have our cars serviced by people like Transporter? And don't let me start on window tinting or 'paint protection' packages sold at the time of new vehicle purchase

Hi all, I wonder if anyone can shed some light on this please?

My GTI went in for its 2 year service at Camberwell Volkswagen this morning with 24,000kms on the clock. They recommended a decarbonising service for $185. I declined.

Trying to find out what this actually IS, I found this thread on the forum: http://www.vwwatercooled.org.au/foru...ice-58037.html. While the thread discusses what the carbon build up is and that it affects DI engines only, there is not a definitive answer as to whether or not this needs to be done at all! Can someone please advise? A post by Corey makes sense suggesting that carbon build up won't affect performance at all.

Also, a UK forum post suggested that petrol additives can do the job for you. Is there a product in Australia that I could add to the fuel to help decarbonise the valves etc for a lot less than the crazy $185 I was quoted?

Thanks in advance for your help.

I suspect it may be a throttle body clean !!!
