Golf GT TDI 130 smoking when accelerating?

Question

Car: as above, 70k miles, recent service, had cam belt done at 50k.

Hi, I have just bought a 51 plate (2002) golf, but I am experiencing continuous smoke when accelerating. Normal diesels just smoke when heavy accelerating into higher than normal revs (clearing out all the cr*p in the engine), but is then fine for a while. This car seems to be smoking all the time that you accelerate (engine hot or cold).
Does anyone have any ideas? I have read elsewhere that it might be a good idea to put some redex in?
Cheers,
Andy

Answer 1

Injectors probably need servicing.

Answer 2

Almost all of the 130,s smoke on acceleration.Its not too noticeable if your driving but if you looked at the back of the car, they can be fairly smokey. The smoke is a greyish black and this is caused by the engine management system receiving a signal from the accelerator position, then adjusting the amount of fuel necessary and they tend to overfuel to prevent any lag. If the smoke is blue, then its possible that the seals are either gone or on the way out on the turbo. If they have gone, you wont be able to see behind you as there will be loads of smoke.

Answer 3

there is a couple of things that could be that could be happening. i would start by taking it back to the dealer and have them check the injection pump timing. this may mean nothing to you but when using the scanner to check the timing go into 01 engine then 04 basic settings then group 00 then check field 7 this is the temp it has to be at 70 or higher before timing can properly be adjusted then compare field 2 and 9 they should intersect at a point on the graph located in the shop manual. if this does not cure the problem you may have a glow plug inoperative worst case senerio the turbo's seals are going bad usually dont see this @70k usually on very high mileage engines. does the vehicle have any power another know issue is the mass air flow sensor being out of spec. there was a warranty extension to 70k on them. hopefully you find this ino helpful. let me know what you find out.

Answer 4

I'm no engineer, but I think it could be the fuel that is not being totally combusted. I know some diesels as they get older become less efficient, something to do with the injection of the fuel into the valves being out of sync, as I understand it. Getting one of those oils that cleans the grime in the engine would be a good first step. See what happens after that.

Answer 5

If the smoke has blue tinge then oil getting into cumbustion from a faulty turbo seal.Easy to check,just disconnect boost pipe to intercooler from turbo and check for oil deposits.Or could be that valve guides are extremally worn & seals can't cope.for some reason this can be quite common on vw diesels.

if smoke is more black then worn injectors or turbo not supplying correct boost(pressure to low).

best take to a bosch feul injection specilist to have it checked out .

Answer 6

Relax, they all do it. As it's a 130, it's using considerably more fuel on boost than a normal turbo diesel. Even on part throttle your 130 should leave most normal diesels for dead. It's using more fuel on part throttle than a lesser diesel does on full throttle, hence why it smokes under pretty much any acceleration.

The PD150's do it even worse!

Answer 7

If you just had a recent service take it back and tell them since it was serviced you had serious smoke problems. It will be down to them to take a look. If they find nothing then consider trying your own methods. I work for a vauxhall garage and i know that if you start playing with things yourself an then take it back they can refuse to even look at it, so id get someone to look at it first.

Answer 8

you may be getting to much fuel, try adjusting your fuel pump screw back a few turns wont harm it ,if that dosent work someones altered the mileage ,can only be one of those two options my bet is its probably been clocked , redex only good for nice running engine wont cure anything

Answer 9

if your turbo is faulty it might leak oil into the exhaust that burns causing the smoke just a guess

Answer 10

my friend's turbo in his jetta was leaking oil, and caused massive amounts of smoke when he accelerated... try to see if thats the problem.
