alcatraz Posted February 3, 2006 Report Share Posted February 3, 2006 I have tried searching the forum for an answer to this without a lot of success, so I thought I would ask. I have a 2001 Facelift Passat 1.8T Sport Estate (94K on the clock). Lately I have experiencing a lot of noise from the engine on start up. If the car has been idle for a few hours, the engine make a horrid rattling noise on start up, sometime it can take a couple of seconds to kick in. Once the car gets goings it’s fine, and if was then to turn the engine off and then immediately turn the engine over again, its starts perfectly with no noise at all. One point maybe worth mentioning it has been very cold and damp in this part of Kent the last few weeks, so I don’t know if that would play a part. Hope this makes sense, thanks.

[/ QUOTE ] Without actually hearing it it is impossible to give an accurate diagnosis, however, it does sound like the tappets (one or more) are not holding their oil while left standing. I have one on mine which is like this, only does it when engine is stone cold i.e left for more than say 8 hours, there is a tappping noise for about 1 - 2 secs then its fine. Whether you need to spend wedges changing them I really couldn't say opinion is pretty split from what I have read on the various forums. Personally I intend to leave mine for now(80k), if it gets worse........we'll see. You could check oillevel and that you have the correct oil for starters. Suggest you get it checked though in case it is something more sinister. Link to comment Share on other sites More sharing options...
alcatraz Posted February 4, 2006 Author Report Share Posted February 4, 2006 Thanks for that. I have just been out and turned the engine over and I had to hold key for a about 3 seconds before it kicked it. I had the bonnet open at the time and saw the engine shaking like mad before it settled down. As for the noise, yes, I would describe it as a tapping noise and it only appears to happen when engine is stone cold. If you have the links to the other forums, I like to have to have a look if possible. Does your engine fail to start first time? Link to comment Share on other sites More sharing options...
mulkbear Posted February 5, 2006 Report Share Posted February 5, 2006 1.8 20V Turbo Engine 1) F. Light rattling noise from engine at start up C. Lack of oil pressure to cam chain tensioner C. Replacement of cam chain tensioner or clean out block oil feed pick up. Link to comment Share on other sites More sharing options...
alcatraz Posted February 5, 2006 Author Report Share Posted February 5, 2006 Cheers, sounds pretty straight forward...I hope! The other fault is the engine takes about 3-4 seconds to kick in from a cold start, to the point when sometimes I wonder if it's going to start at all.

alcatraz Posted February 5, 2006 Author Report Share Posted February 5, 2006 I have attempted to attached a sound file wich, I hope will give some idea of the problem. The car has been standing for only around 3 hours as it had a good run ealier in the day, so as a result it does start ok, but you will hear the tapping noise is present. You will also notice when I turned over the engine for the second time, the tapping noise had gone. 700672-V005.zip Link to comment Share on other sites More sharing options...
steve2 Posted February 5, 2006 Report Share Posted February 5, 2006 That does not sound too healthy!! it sounds like a diesel initialy, mine certainly does not sound like that and it has higher milage than yours. It does sound cam related and i would get someone to look at it quite soon in case it gets worse Link to comment Share on other sites More sharing options...
mulkbear Posted February 5, 2006 Report Share Posted February 5, 2006 The starting fault is linked to the nosie on start up, as the twin cams timing is knocked out when there is limited oil supply to the cam chain tensioner as it is also a adjustment for the cam chain which is run on oil pressure.

alcatraz Posted February 5, 2006 Author Report Share Posted February 5, 2006 Thanks, Its going down the garage next week for its MOT, so I will mention this. Any ideas how much this will cost to fix? The other problem, I have is a slight droning noise from the rear wheels, I am told the wheel bearing is starting to go...any thoughts? Link to comment Share on other sites More sharing options...

mcnalu Posted February 14, 2006 Report Share Posted February 14, 2006 On the wheel bearing noise: I was driving my Seat Toledo up the M6 at 80+ mph in the rightmost lane overtaking heavy traffic when a terrible grinding noise started coming from the back of the car. Any attempt at using the steering and brakes was VERY scarey. So I stuck my hazards on and hoped people would understand. Luckily they did and I just drifted across the three lanes onto the hard shoulder and slowed down using the gears. When I got out and looked back I saw the rear nearside wheel was about 30 degrees to the vertical. In the fortnight or so before that I heard a faint, intermittent noise coming from the back of the car - the wheel bearing was on its way out.

The bearings are usually quite noisy before you can see anything visibly. Naughty boy doing 80+. Link to comment Share on other sites More sharing options...
mcnalu Posted February 14, 2006 Report Share Posted February 14, 2006 They can be noisey, but the Passat is a cocoon of sound proofing. When my alarm goes off on the driveway it's actually quieter inside the car than inside my house! Oh yes, that would be 80 km per hour, officer.

alcatraz Posted February 21, 2006 Author Report Share Posted February 21, 2006 Wow, that would have freaked me out! The car was checked last week for its MOT, and I asked for the wheel bearing to be looked at. I was told that it was not an issue, but to keep an eye on it, although as I can't see it, I will listen out for it instead! Link to comment Share on other sites More sharing options...
alcatraz Posted March 15, 2006 Author Report Share Posted March 15, 2006 Finally after a long haul the car is fixed! After my local independent garage was not able to diagnose the problem, they suggested I take the car to a VW dealer….there goes my bank balance I thought! Luckily we have a SEAT dealer in Dover, they used to be VW, but that’s another story. They still have VW technicians and mechanics on site and are a cheaper than the VW dealer in Canterbury. The car went in on the 15th Feb and I was pleasantly surprised to be told that the problem was down to having the oil filter replaced…great I thought..but alas that did not solve the problem much to my dismay. Then it was suggested they replace the oil filter housing and oil pressure check valve, this was going to cost 140 quid (Inc Labour), so I though about and then though what the hell. So back the car went, a few hours later and some new parts and guess what….same problem! So what’s next I ask, well the man said ‘we can replace the camshaft chain position tensioner’, I said ‘how much?’, he said ‘320 quid plus labour’. This was going to cost around 500 quid in total. Then the man said, ‘seeing as we messed about with this, we will not charge labour’ Anyway to cut a long story short….they fixed the part and fixed the problem. Total cost for all the parts and labour £460. As for the other noise which I was told was the wheel bearing going, well that turned out to be loose piece of plastic housing that had come loose and was vibrating, they also fixed that for free!
