Does anyone know how noisy/quiet a TDI150 engine should be? I've driven diesels (other makes) before but I expected this one to be quieter than it actually is. Seems to give off a 'tappet-like' noise when accelerating. Nothing extreme, I just wondered whether this is normal.
cheers!
-
depends on which gear you are in; if you're in a high gear but low speed then sometimes it can make a bit of a racket lol
have you checked your oil level to make sure thats ok?
-
can you explain 'tappet-like' noise?
-
Rhyso - Oil is at about 1/2 full.
The_Ridge - not sure if diesels have tappets but it's the sound of the valves opening and closing I think, a sort of high-tone knocking.
-
that doesn't sound quite right.
when mines idling you get the distinct diesel noise but thats no louder than anyother and with the windows up you can't really hear it.
under acceleration the main noise i hear is the turbo forcing air in, similar to an induction kit noise.
do you get the noise if you rev the car stationary? and is the noise constant?
-
The main noise is the turbo, the 'tappet' noise is only really noticeable when revved i.e. the more it's revved the loader it gets. Maybe just low oil..

lets hope its the oil, the only other thing that springs to mind could be one of the engine mounts or something.
-
jeez, don't scare me! Pretty sure it's not that serious. I'm taking it to VW in a couple of weeks so will find out more then. Need to ask a question about the oil though, if I just want to top it up, what is the best oil to get, and should I go to VW to get it?
cheers

EDIT: assuming your on fixed life service like me
i use Castrol Edge Turbo Diesel 5W-40 you can get in in halfords see link
link to halfords (http://www.halfords.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10151&storeId=10001&productId=164264&categoryId=53252&langId=-1&parent_category_rn=53252&crumb=33958&varient=&CarSelectorCatalogId=&CarSelectorGroupId=)
its not cheap but its specifically designed for the PD engines. you can use the halfords own brand stuff just make sure its got 505 01 approval
i'm not sure how much VW charge for their oil but would have thought it would be more than halfrods
EDIT: the edge and edge diesel are pretty much identical so its easy to grab the wrong one.
-
think so, it's due a service in about 1500 miles. Was just going to top up beforehand.

oil and oil filter are part of the service, so if you do buy some, only top it up otherwise you're wasting money.
-
Cheers. Will do . Will let you know whether the noise is actually normal or me just being paranoid! Only had the car 3 days after driving a 1.8T for 2 years so maybe it's just a case of getting used to it.
-
I know what your on about regarding the 'noise'. Mines exactly the same and asked main agents about it and they said there was nowt to worry about(WTF that means is anybodies guess :laugh:)
-
Mine has just recently developed a similartapping noise on acceleration. Can only hear it with the window down, but it does worry me.
I've checked the oil and it all seems fine. The only thing I can think of is that it went for a service last month to a garage I don't know...I hope they've put the right oil in! What would be the effect of using cheap/low grade oil?
-
If its a deep noise when putting your toe down lol. It could be your intercooler pipe comming off a bit.
My mate has the fr tdi 130 ibiza and his intercooler pipe has come off twice. Seat said the turbo is over powering or somthing.
-
ah you might have hit the nail on the head there. The intercooler pipe has worked itself loose before, but the effect was much more dramatic (no power and loads of smoke).
I'll check it out, cheers.
-
if the pipe does come off then you'll have no power above 2000, really bad economy and loads of smoke
you do get cases where the pipe is partly out at which point, you'll get some smoke and some loss of power
-
The first time it went wrong on mates it toally came off and smoke comming out.
2nd time you could here this load annoying noise. I say mate it needs checking. And what do ya know its the pipe again lol.
Check ya pipes dudes lol.
-
OH NO !!!!!!!!!!!!!!!!!!!!!! :angry:
It seems my problem was due to the wrong grade of oil being used at my last service! And I thought I was being paranoid. I wont name the garage....yet. I'll give them a chance to admit the mistake they've made and put it right (i.e. reimburse me for the repairs to be done by someone who knows what they're doing and the cost of a hire car).
The repair bill is going to be in the region of £1500 and I'll be spending another £100 on a hire car!
I gave up with VAG-COM in the end, got no error codes and I'm not good enough to use the measuring blocks and scope properly yet. (Any one got any info on this btw)
I found a small local VW specialist, who seems to 1: know his sh!t and 2: actually give a sh!t. So i'll be going to him from now on, all going well.
-
have you got cam wear issues??
-
are the garage going to pay for the damage they did through negligence then?
they should do, becuase if they have put the wrong oil in then its their fault
-
Rhyso - yep cams need to be replaced :cry:
The_Ridge - The garage that carried out the service are sending an inspector out to take a sample of the oil.
Once they have the result back from castrol (48hrs) they will know for sure if that was the cause. If they are at fault then they will be paying for the repairs, if they find a way of wriggling out, i.e. if there's any doubt about the cause, then I'll be stumping up for the bill and spreading as much negative press about the garage as possible.
Something I keep having to tell myself is, even if I have to pay for the work, the engine will have a whole new lease of life. So, although I wouldn't have chosen to do the work, it being done isn't all bad.
-
Well...over a week later I'm told that the oil that was in the engine was Castrol Edge 5w30, which the inpector says is the correct oil. The engine specialists carrying out the repair work aren't so sure.
I'm sure that I've always used 5w40. If I do a search on castrol's site and use their Lubricant advisor I get to the model page http://www.ew2.lubesinfo.com/login.asp?sc=1156 (http://www.ew2.lubesinfo.com/login.asp?sc=1156) and quickly get confused.
I can narrow it down to two different models:
Golf 1.9 GT/GTI PD (QG1 - 96/110kw)
Golf 1.9 GT/GTI PD (QG0/2 - 96/110kw)
The one labelled QG1 is stated to use 5w30 whereas QG0/2 states 5w40. Anyone know how I tell which model mine is? Or, is the site suggesting that both oils are suitable?
I noticed that the product info for the 5w30 doesn't mention PD engines, whereas the 5w40 specifically states "Specialist product for VW PD engines requiring the 505 01 specification"
-
i've always used 5w40 as mines on the fixed interval service
this is from the halfords site
http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_198255_langId_-1_categoryId_77304
Peace of mind - right oil for VW diesel fixed servicing cars This product should not be used in PD models equipped for VW Longlife extended service intervals (indicated by the letters QG1 on the VIN plate - see handbook for details) as Castrol Edge 5W-40 contains the specifications for these vehicles.
check your VIN number or handbook and find out if you're meant to be on fixed or variable servicing. if you're on fixed then you should be using QG0/2
the only problem with this is that certain ways of clearing the service interval can force the computer into fixed interval, so although your vin says variable the computer has been told its on fixed.
EDIT:
just had a look at the castrol site
c. Service Interval Display - if the listed Longlife oils are not used the display must be changed to show 'non-flexible' and the reduced service interval implemented
so its going to come down to what mode your service interval is on, if you're on fixed then they have fooked up, if you're on variable then its correct.
-
this is a well documented fault with the pd engine especally the 150 ours has had a cam and followers my mates has had a cam and followers and the local garage has done a few. people say its the wrong oil but there has been problems with cars which have been using the correct oil from day one, also i have heard that the cam is made from a soft metal which is not up for the job,
my mate got his cam changed about 8000 miles ago and it has had 2 oil changes since with the correct oil and when he was having running problems with it before christmas he took the rocker cover of it just to check there was wear marks on the cam.
i dont believe its the wrong oil because there was a pd 130 owner my dad knew and he did his own servicing from day one and he did not use pd spec oil cos he did not know about it and the car ran for 140000 miles with out a problem, and our car had a full vw service history when we bought it (means nothing cos there are many dealers that didn't use the correct iol in these cars) it got its cam at 97000 miles its done 150000 miles now and its coming up to a service and i will be checking the cam cos if there is any wear marks it will be going back to vw cos they have a 2 year warranty on all parts and the cam will just be under 2 years old

I've got my VIN number, how do I tell if it's fixed a variable?
-
apparently it should contain either QG1 or QG0 i'll check mine later and confirm that the code is actually there.
if not its one of the option codes that are in the service book, this i've seen so you could check your option codes, if you don't have the book then VW should have a log of what options your car had.
-
I couldn't figure out if I was on fixed or variable from the VIN, so called VW.
They've told me i'm on time/distance based service interval and recommend I use 5w40 505.01 spec. I've emailed the garage's manager, see what he says. I'm really not holding my breath anymore.
But...
Got the car back today :grin: ...and, I'm not sure if its just cos i've been getting the bus for the last few weeks, but it seems sooo much quicker :laugh: So happy with the work my new garage has done for me.
In the end I had the following done:
- New camshaft
- 8 New hydraulic tappets
- Cambelt kit
- water pump
- Engine flushed twice
- New oil (5w40!!) & filter
-
yeah the site that said it was on the vin number was wrong, its actually in the options list (in the service book)
either way, they have put the wrong oil in
good to hear you've got her back and that you're happy with the rebuild, now just to get your money back.
-
Well, the sage still continues :angry:
The regional manager for the garage that did the service is still standing by his opinion that oil used was suitable for the car and doesn't "know where VW are coming from". He assured me that his contact at Castrol would call me to exaplin but that was coming up to a week ago now.
I'm gonna call him on Monday and tell him I'm going to the small claims court, anyone know any good solicitors in this field?
-
Sorry to bring this thread up :laugh:
Spydoor can you tell me the garage you used to fit your new cam etc as i'm in middlesex and could do with a decent VW garage
Thanks
-
Yes and how much was all this??? as I think mine is next!!!
-
Whats the matter with your car Simon :huh:
-
local vw specialist said my engine sounds louder than it should. he suggested taking the pipercross filter out, as he noticed it was slightly bowed in the middle, so could be reverberating around in the air box. swapped for the old one, and doesn't seem to make a difference to my untrained ear. or he said could be the cam on the way out. 700 to replace he said. is that normal???

hmm sounds weird
£700 mind is a bargain lol!!
-
lol oh good!!! i might try to wreck the whole engine then, and then get him to re-build it all it for a bargain price!!! the more i spend, the more i'll save!! brilliant idea!!!
-
Ah sh!t :cry:
take the cam cover off and look for damage before doing anything else
700 is cheap, is that with parts? as they come to around 500 :undecided:
-
i'm not sure if it is with parts really mate- didnt ask too much about it. having a service next month so will get vw to have a look at it. but yes will have a look myself over the next few days. been mullering the interior trim recently, so have to put all that back together too- looks like its been broken into!!!

I take it to a local guy (Feltham) who has a small garage, but for big jobs like the one I had he takes it to another place, who's name escapes me. I'll see if I've got it on any paperwork anywhere.
Yes and how much was all this??? as I think mine is next!!!
For the following:
- New camshaft
- 8 New hydraulic tappets
- Cambelt kit
- water pump
- Engine flushed twice
- New oil (5w40!!) & filter
It cost aprx £1600 for parts and labour.
