GT TDI Golf

whacker4fun

Bought a GT TDI golf 130bhp but as far as I was aware when I bought it, its been rmapped to 150bhp.....now I have drove the 130bhp and this is faster!
Anyway, I have it maybe 3months and the air flow meter went in it and its started to pump black smoke out of it, it got fixed and the warning lights went off on it............but since that really I have noticed that its started to pump black smoke out of it again,....not just on a quick take off but even when im cruising at say 70mph....it will suddenly do it for say 10sec and then will stop. My concern is that often just before thsi happens I can feel a stutter on the accelerator pedal ( like its chugging on dirty diesel....which its not) and then i see the black smoke....no im no mechanic but my thoughts are there is some filter gone in it or its burning oil!!!!!!!!!
any help ,....im not happy with it so I will be bringing it back to the garage.

Mr. Presentable

Sounds like a faulty turbo to me. I'm not a mechanic either, but black smoke usually means too rich a mixture, and implies the turbo is not supplying enough air.

Nice car, though

whacker4fun

that could do serious damage????am i right!

Gumbo

i thought the GT TDi was 150bhp standard???
get somebody with the diagnostic equipment to check the car for fault codes.

whacker4fun

so did i, until i did a bit of research, you could buy a mk 4 golf gt tdi 130bhp and 150bhp. but the new one a different they are standard 140bhp 2.0 gt tdi.
the gt tdi 130 bhp can be remapped to 150bhp but the 150 bhp can be remapped to 190bhp....the only difference between the two is a walnut dash on teh interior......but if im wrong please correct me!

I did get that done and the air flow meter was the problem but thats been fixed,maybe it wasnt fixed properly

The GT TDi doesn't exist in Ireland. It's a creation of VW UK.

Basically it's a GTi spec car with a diesel engine. The VW UK badging of the Mk4 Golf was left up to the individual dealer so there are totally inconsistent.

Don't think they ever bagded the basic 90bhp model as GT TDI but you can get them in 115bhp, 130bhp and the rare 180bhp. Both the 150 and the 180 came with 6 speed gearboxes so thats the major give away. Other wise the engine code or the sticker in the boot/service book is the only way to tell which model they are (value givin in kW so add 1/3 gives approx bhp)

impressed on your knowledge of the gt tdi golf,very few people know crap about them.....the gt tdi 130 is 96kw and the 150 is 110kw this is on the sticker in the spare wheel area in the boot.
Mine was brought in from the uk by a dealer down south, i intend bringing it down to him to sort it......i was doiing 100mph on the N4 today and not a puff of smoke and then when on the m50 thsi evening i was doing 60mph and it puffed black smoke.....any ideas lads???????

You might be best of searching through some of the specialist VW or even VW TDI forums around (mainly UK based). Just google them and you should find a few.

Your probably best off going back to where you got it if it's still under warranty. If it's not let me know and i'll PM you the number of a very good mechanic in the Naas area who served his time with VW.

There were in fact 4 versions of the Golf GT TDI. The first and oldest was the 110 bhp with a 5 speed box. Next came the 115 bhp GT TDi PD with either a 5 or 6 speed box in about 00. In either late 01 or early 02 this was replaced by the 130 bhp version with a 6 speed box and not long after that came the 150 bhp version in addition to the 130 bhp version also with a 6 speed box. Surley the malfunction light has come on?( an orange boxish shape not too dissimilar to the battery light without + and - that would be in the centre of the battery light).

Theres no such thing as the 1.9 TDi with more than 150 bhp, and the 90 bhp was never available in GT format.

yea it did come on and i gave it in to a diagnositics guy and it was the air flow meter, got that done but its started again,im wondering was a cheap air flow meter put into it.

I stand corrected Fletch. Completely forgot about that car.

@Whacker4fun I dont know if this is any help to you but the malfunction light often comes on to indicate that exhaust emissions are too high. That suggests that there is more than just an air flow meter at fault(highly unlikely but it could be something in the catalytic convertor, though that said a loss in performance would normally be attributable to problems with this). What about the ECU? After all this controls what an engine does pretty much. It decides how much diesel should be injected, what the fuel/air mix should be, how much boost the turbo will give etc. Get that checked out for a start, if doesnt give any fault codes my instinct would be to get another ECU and see what that says. I'm no mechanic or technician as they are called these days.

Going back to difference between the 130 and 150 TDI Golf, the 150 has TDI while the 130 and 115 have TDI on the hatch door. The engine is exactly the same, other than the ECU is remapped and IIRC the turbo is a little bigger. The 130 and 150 are identical otherwise. And it was possible too to get the 150 with GTI written on the back of it as well.

In relation to the new Golf the GT is available in 3 formats; 170 bhp petrol, 140 and 170 bhp diesel. The new Golf GTI has a 200 bhp 2 litre engine.

The other problem is that you have a car with a re-mapped engine, not a wise idea buying a car thats been chipped, especially if the problem warrants the car having to go to VW to get sorted, they're not going to be impressed, and will tell that the problem in your car is caused by the fact that its chipped(whether thats true or not is irrelevant, I would be 99% sure that that is where they will 'find' the 'source' of the problem to be).

whacker4fun

the only real way is to check the log book of the stciker in the boot to see if its 130-150....young lads are just getting the GT sign and sticking it onto TDI's that have red D and I.
Ye ive a feeling they wont be to happy but as far as im concerned I bought the car like that......there could be an issue tho about taxing it.....:D
I intend to act stupid to the fact that its chipped.its actulally looking like the dealer i bought it from will fix it....I had a mechanic looking at it and he says it could be oil seeping up through the pistons,....its getting a quick look over this week and then ill be on to the dealer.
when the diagnoistics was checked the only fault was the filter....and the light did come on and there was high smoke emissions but that was fixed but its returned.

The Golf GT comes in 170bhp 1.4TSI and 2.0TDI form . The 140bhp variants are not GTs just badged 1.4TSI and 2.0TDI available in Sportline trim.

whacker4fun

when we are talking about golfs...does anybody know the difference between glass reinforced plastic GRP and ABS plastci bodykits?????
which is better or are they basically the same.
I know that fibre glass are brutal but which of the above is better

This seems to be a field day for me making mistakes:D

Again spot on, I was getting confused with here and across the pond, where the MkV Golf WAS available with said 140 bhp engine.
It no longer is available, as GT Sport trim has replaced the GT and Sport trim over there. The 140 bhp unit is available in GT Sport trim over there.
Tbh whacker4fun I havent a clue which is better. But fibreglass feels awful anyway. I think its horrible.
