2006 GTI MKV, Ticking sound from engine

Hi,

I have a 2000 Golf that has sustained some front end damage.....am looking for the following parts:

o Left Front Fender o Front bumper cover o Hood o The part that goes across the front that the headlights and the hood latch bolt into. o Perhaps another misc. part or 2.

Thanks in advance,

Brian

Could be a number of things, of which knocking is one. But before going any further a few questions:

a) What kind (and weight) of oil is in the car, and when was it last changed? b) Are you experiencing any sort of overheating? I assume that the car has a gauge, is it reading any *differently* than normal? c) Please define "lack of power". The follow-up question to this is when is the last time your fuel filter was changed? Sometimes a load of bad gas (or running the tank down to near-empty) can put a marginal filter over the line.

Let us know for further suggestions. But if you have hydraulic valve lifters with "winter-weight" 0W30 weight oil, they will tick some when the engine gets hot sometimes.

If your fuel filter is plogged, you will run lean, which contributes to knocking, overheating and lack of power. Computers are very good, and can do the improbable... but not the impossible.

Does your owners manual specify what octane rating should be used? If it says 91 or higher, and you used 87, then probably the noise is due to engine knocking and will go away when you fuel up with the correct rating.

As for ARCO gas stations, there are none in this area that I know of (central Ohio), but gasoline brands have never been a concern. I have found them all to be about the same quality, so I buy according to the lowest price. Fortunately for me my cars (a 95 Buick Roadmaster and an 88 VW Cabbie) perform with no problems using 87 octane.

You should really create your own thread rather than insert your post into the middle of a thread that has nothing to do with your situation.

Thanks folks, I appreciate the help. To address your questions.

The oil was last changed in October 2006 at 10,000 miles - about 3500 miles ago. It was filled with ZVW 352 540 S, 5W-40 synthetic at the dealershop.

Engine temperature has been right on 190degF and hasn't differed since I bought the car last May.

Lack of power? Not really noticable with ordinary driving, but with foot-to-the-floor and higher revs, the car seems sluggish compared to what it was before this "fuel event."

The owners manual says to use premium (91 octane, 95 RON minimum) but that regular is acceptable. It also says that anything less than 87

acceptable and IIRC up to 3% methanol is acceptable. ARCO in my area is noted for it's relatively inexpensive gasohol. I believe they use 10% alcohol, but I don't know if it's methanol or ethanol. I filled the car with ARCO premium, but I confess I didn't read the octane rating. I guess I just assumed that premium gasohol wouldn't have a lower rating than regular gasoline.

The fuel filter has never been changed, but at around 13,000 miles I wouldn't have expected it to be necessary. However, I am one of those guys that fills up when the light goes on. Perhaps I should change my ways....

This is OK every so often, but not as a habit and not if you purchase at low-volume stations.

Worst times to purchase gasoline:

a) Just before a delivery. You are sucking dregs. b) During a delivery. The dregs are being stirred about.

Fuel filters *should* last 30,000 miles, all things being equal. However, all things are seldom equal. We maintain four vehicles at this moment and we have a spare fuel filter on the shelf for each one for that reason alone. Depending on your peculiar (in the sense of specific) circumstances 13,000 miles may be a stretch. But if you are not having problems under normal conditions, run a can of Techron through at the next fill-up and see what gives. If the condition remains, change the filter.

I thought some of you might want to hear about the resolution of the Ticking Sound. When the tank got down to about 1/4 I filled up with Shell premium. The ticking sound didn't quit immediately as I had expected it would. So I called the dealer service department. They thought it was probably the "evac valve" whatever that is. I had some trouble understanding through his accent, but I think that was what he said. Nothing to worry about, he said, a slight ticking is normal. However, he couldn't say why the car hadn't ticked this loudly prior to using ARCO gas. They were willing to take a look at the car if I wanted. I drove it about 100 miles and the ticking continued. Then checking the oil, I noticed the level was about only 1/3 of the way up from the "fill" mark. So I topped it off. In about a day, the ticking quieted and then stopped. Not a definite cause and effect. My thought is that the car isn't >that< sensitive to oil level - as long as it's above the fill mark, but I'd rather be close to the "full" mark. I don't think oil level was the problem. I did notice that performance and mileage (based on the display) improved gradually after filling with Shell gas. And the ticking gradually stopped. So I think the gasohol from ARCO was the problem and that the computer takes a while to re-adjust itself.

I have the same exact issue. I have already brought my 2006 GTI back to the dealer and they tested it, without finding anything.

I did find this TSB

and thought I discovered the issue.I called the dealer, with the TSB info, and they said it doesnt apply. I hope the noise just goes away when I fill it up again
