I hear a weird noise form the engine when I depress the acceleration pedal. Engine is also a little louder than it used to be. Could it be because I used the 87 AKI fuel once? Thank you.

It sounds like a creaking wood floor in an old house but it only happens for a second but it happens every time I step on the acceleration.

Its not very loud but I'm just wondering if it normal considering I used the 87 AKI fuel.
Will it occur if you're sitting still with the transmission in neutral and you shift it into drive without touching the accelerator?
What I'm wondering is if it's motor mounts...
Lower octane gas will just reduce available power as the computer retards timing to reduce knocking. I always run premium because I'm stupid and like maximum power. LOL!

I had a similar sound on a 2010 Jetta TDI... on mine it was strut tower bushings...mine would do it over speed bumps as opposed to throttle, so yours likely isn't this, but some bushing or motor mount...problem is mine wasn't broken, just noisy...so hard to find.

It happens when in park as well. Its really slight but my paranoia makes sound louder. I put premium fuel back in. Will the timing return to normal??

Thank you for your reply
I don't know if it made that sound prior to putting the 87 AKI fuel in it. I'll take it to the dealership next week. Hopefully my extended warranty covers the problemYes, the computer should sense that it doesn't need to pull timing anymore and it should go back to "normal".
If mounts are creaking, they could possibly make noise with the tranny in park, too. I've seen the old AMC 360's jump up in the engine bay with bad motor mounts, mostly when in gear, but sometimes in Park or neutral.
If you have the extended warranty, take it in. Just make sure they don't have a a minimum shop charge or just be aware of what it is. I'm not sure they'd cover a visit to diagnose a noise they may or may not be able to hear.

Thank you for your reply. I'll go to the dealership next week and have the mounts replaced and the engine checked. The engine is already starting to sound like it used to since I filled it up with 91 AKI.

Turns out my timing chain tensioner was the culprit. A new timing chain kit will be put in next week.

Based on engine being an 06' (non FSI) I assume timing belt tensioner, not chain?

neither would i. the dealership quoted $5000 to get the faulty tensioner replaced but i found an auto shop who are fixing it for $2000. they will be replacing the chain as well.
Heck Yeah!!!! I'm glad i bought the warranty

i dont know about the v6 model but the v8 has both the belt, which is located in the front of the engine and the chain, which is in the rear.

The V8 from 03-06 didn't have timing chain. From 07 on is timing chain in V8.
All V(R)6 Touaregs are chain.
Based on yours being an 06' V8 and what the dealer said...I too would want an explanation of what part they are talking about.
The cams (on either head) have a chain for the cams (the timing belt drives one cam on each side, then the chain (under the valve covers) drive the other cam. See post #6 in link below:

The dealer cost is too high for a timing belt, so I am thinking cam chains?

just got off the phone with a mechanic friend of mine. You are right. the v8 does have the chains for the cam and not the timing chain. that is what is being replaced. The tensioner(s) is/are being replaced too. the dealer was going to charge me $120/hr. 7 hours for each side.

OK this makes sense. The independent shop is a good idea for this too.
