Hey - right, I'm in need of some fault diagnosis help.
Noticed this fault the other day driving. It was ok yesterday, but then came back today.
I'm meant to be driving down the Lake District on Wednesday, so I'll need it sorted by then.
Right, here goes:
When driving in gears 2,3 + 4th its noticeable.
Revs are low, around 2000 rpm, when I try and accelerate there is no power, the revs rise slowly, to a point where everything kicks in to normal power. The best way to describe it - is like driving 2 or 3 gears too high and accelerating (nothing really happens).
When I got home, I popped the bonnet, and could smell burning around the back of the engine.
Do you think this could be the clutch on the way out? To begin with, I thought it was engine related, but I'm not sure yet.
There are no other symptoms that I am aware of.
If it is clutch, how much are they for a garage to replace?
Cheers
Chris

Get an 8 valve :grin: 16 valvers dont have a lot of torque low down, dont think it could be the clutch or engine would be revving.
-
Blocked breather or throttle body gummed up.
-
Ok.
Any ideas what the burninbg smell could be? I do have an oil leak from the filter i think.
I've been reading a post about oil getting into the distributor? Any ideas?
Its not normal.
I've had my car for three years, and its driven most days.
Definatly something untoward.
-
Does the car 'judder' just as you release the clutch when pulling off the spot? My 8 valver does this, possibly the low down torque puts more pressure on it on take off! :tongue: :evil:
-
Haha.
Not really noticed any real judder.
I floored it coming off a roundabout earlier in 2nd.
VERY little response with the revs, and it did feel kind of like it was wheel spinning - although it definatly wasn't, so I suppose there was a bit of a judder.
-
Try changing the fuel pump and ecu relays.
If you think there is still a problem, put it on vag com.
-
Cool.
Fuel pump will cost around £50.
Relays around £10
That about right?
To be honest, I'm thinking about taking up to the dealers tomorrow and see what they think.
Just want to get to the bottom of it without faffing around.
Wil advertsie a local forum for Vagcom.
Ta!

No, fuel pump relay and ecu relay :smiley:
-
Ok. Cool. Saves a bit of cash!
Am I right in saying (well, just read in the maintenance section) that if the relays are goosed they will be cold after driving round for a bit.
I'll take it out for a drive in the morning and see if they go warm or not.
-
I can't remember. I know i changed the relays on an ABF that someone worked with me owned.
It was hesistant, but worked great after the relays were done.
-
Cool.
Cheers for the comments.
Any other ideas folks?
Will be checking out the ideas in the morning.

The other thing to do is remove the throttle body and clean it with carb cleaner :smiley:

No need to remove it. Just use an old toothbrush and carb cleaner and reach in as far as you can.

If it is your clutch the engine revs will increase without the speed increasing very much.
Burning smell could possibly be the clutch slipping, very distinctive smell.

Valvers have the same low down torque as an 8v :smiley: :grin:
But I have heard from certain owners that the impressive 8v torque and power out puts rival the Enzo :grin:

For cleaning the throttle body, do I take the pipe off from the airbox?
I'm more concerned about this burning smell.
It is distinctive, and I definatly think its got something to do with it.

Actually valvers have more torque than 8v but it is achieved at 4, thousand something, where as the 8v acieves its at 2, thousand something. Thats the difference.

Much better to remove it, you will definately get all the crap out, and it won't go in the inlet manifold.
Its a simple job to do, just need a new gasket :smiley:
-
Ok. Will do that in the morning.
Am I right in saying that the throttle body is the bit on the engine side of the pipe between airbox and engine in the picture yeah? Where the plug goes in.
Is it easy to remove?
About to do a search for it on here.

Is it worth doing that on a car that appears to be running ok as I have only ever cleaned mine as far as I can get my finger in with a cloth?
-
If you are worried about clutch slip then put it in 5th and try and pull off.
If its gonna slip it will then :smiley:

I would. Its good practice to do on an old car. Cleaning it in situ will not get all the crap off.
Much better to remove so you can clean the back of the butterflies properly.
-
Proper job boys!
Will report back tomorrow with a whole host of other problems no doubt!

No, the torque curve on the 8v and 16v is very similar to about 2500rpm to 3000rpm when the 8v tops out and the 16v continues to increase all the way up to about 6000rpm.

Right - drove around this morning for around 30 mins. Town driving, which gave the problem plenty opportunity to show itself, but it didn't miss a beat.
Bought some degreaser and just cleaned out the throttle body. The housing wasn't too dirty, so will see if its made any difference later.
