1.9tdi mods

[vwlova]

Hello all 1st post of the forum.

I have a 2004 1.9tdi 130 bhp se passat that i want to give that extra perfomance. I really love this car but want to chip it and make around 180 bhp. Anyone recommend any mods to make as this is my 1st time making mods to a car.

I really do love thi car and drive it very sensible ( but love the perfomance) so is it worth the extra perfomance and does it exchange any longevity?

many thanks.

You can achieve 180bhp with a remap alone.

No extra hardware mods are needed.

As with any power increase, there will be more wear and tear, but the engine is very strong, and will last.

The main point of concern will be the clutch, which can be upgraded when it eventually wears out.

180 bhp is pretty impresive. I think i should point out i use the car as a taxi and treat it very well. It was my dream car when i bought it and a bit gutted i have to use it now as a taxi but its been a very very good car.

I think i may get the remap done soon, youd be surprised how much some taxis have beneath the bonet and run for years but im always a bit cautious.

can anyone recommend anywhere around norfolk?

Thanks for your help.

If the car is mainly used as a taxi, i would recommend not pushing the bhp as high as possible with the remap (maybe keep it around 150bhp - 160bhp).

The mpg can suffer on aggressively mapped cars.

Thanks for the reply, i have found a local perfomance place which have been recommened. I will be chatting with them too. I have read that certain things can improve mpg. As you can tell i have no clue about any of this really .

I want the car to last another 4-5 years and it has done 86k but really want that lil extra. Some people are using crazy cars now for taxis some pretty big beasts and they seem to last so thats what made me thing that moding it will be ok.

Hi...Ive read elsewhere in this forum that engines are de-tuned to manufacturer's specifications.....

If Im considering a remap...is there an level at which the engine will operate most efficiently? In other words, I dont want to have it tuned up so that fuel consumption suffers....so...is there some way of maximising fuel efficiency AND power?

if you want mpg leave it well alone you cant have your cake and eat it so to speak.
i had my car remapped i was so shocked :zx11: with the decrease in mpg i had it put back to as it was.

I'm thinking of getting a re-map / chip. All the web sites i have been to have stated that a performance increase & a MPG increase is possable.... Is this true :confused:

[ini]

The only real way of getting more mpg, is to use the increased torque to drive around at lower rpm's (higher gear).

This does work, but needs a good workout every now a then to keep the VNT mechanism in shape.

You could also get a tuner to alter the mapping so that extra power is only seen at WOT, or an instantly switchable solution.

Some of the newer injector nozzles can potentially offer better mpg's (PD & VE).

try this - worked for me - power gains were fantastic + extra smoke on take off.

[minty0_10]

what about the mpg?

[passat 130 tdi]

same if not a tad more , if that question is aimed at me ??

just take a look at my signature, it is true, im 33 and dont have a light right foot, 30 mile journey to work with 143hp up from 110hp sees 60+mpg with sometimes the figure below if its a line of traffic i cant pass. used to be about 51ish mpg average now i have to be driving the nuts off it to break 50mpg and that just doesnt happen.

[minty0_10]

there's a difference in engines here mind pd in the 04 car and a afn in your 110

ive had both types while the pd engine is smoother and more refined its a but more thirsty so start, with i had mine remapped and it started drinking diesel like a alcoholic who smokes 40 a day:mad: i soon had it changed back.

the older 110 engine is more economical than the pd and i think a better engine to start with.

point being maybe the afn engine responds with better mpg than the later pd engine

does that make sence:Blush:

[smokey0123]

I think the increase mpg is true if you drive it sensibly as the engine has more torque, but if on the otherhand you drive heavy footed expect less mpg than standard.

[minty0_10]

that's true but where's that extra torque come from? it comes from the turbo being worked harder witch in turn uses more fuel?

i drove my passat like little miss marple for weeks and it still drank the fuel.
maybe just my car

[smokey0123]

I think they are very detuned from the factory so they are smooth,quiet, pass a strict emmisions check and dont smoke when you buy 1 new, the emmisions check for the mot is nowhere near as strict so i think remappers take advantage of this to get lots more power/torque by changing injection timing, quantity possibly egr settings, fuel pressure and boost pressure?
Hopefully 1 of the chip tuners on this site will come along and confirm?

Theres very very poor feedback on this item ranging from him being called a fraudster to someone claiming the item was a 5p resistor and caused problems with the ECU !

I need a touch more power from my 100bhp 03 Passat 1.9 TDI,
Does anyone have any practical advice regarding whats involved to upgrade , what sort of bhp I can realistically expect, and a 'guesstimate' of probable cost. Also looking for advice on where in the N.W. I can find a reputable company that would do the work should it be beyond my DIY skills?

Thanks

I had one of those installed in my 100bhp 1.9 Tdi.....I took it out after a few months.

Do the math!

big shout for the afn!! drove conservatively today and didnt overtake all the way home, after 23 miles i pulled over and took this photo

boot full of stuff including the gf's spare wheel and new tyre, 4 bags of clothes for the charity shop, black bag full of my trainers, halfords pro tool set and a few other bits and bobs, pretty much full tank of juice too, i would shout to all the afn engined owners to get remapped/chipped cos it so obviously doesnt affect the mpg, if i drive it really hard to work i still get 50+ car is 143hp and running fine

i get on average 49 mpg at 60 mph . 38 mpg at 70 mph . i take no notice of the fuel computer , if you back off the throttle a tiny bit it can read 116 mpg which is nonsence.

[jamoca]

Do the remap!


My average fuel consumption has improved by 6-7mpg, and as for power - check out my sig!

that's a photo of your instant mpg its the average you want to be looking at

[ssray]

Your first port of call should be a decat, remove the cat` and have it replaced with a straight through bit of exhaust pipe-important-of the same diameter as the rest of your exhaust, on my old rover 420 it meant getting in top gear sooner with added oomph, you dont need a cat for the mot as diesels are tested for smoke/particulates not emissions and the cat deals with nox, not co2 etc like on a petrol engine.

[hongkongstuey]

no it isnt? its the average, the instant changes with the throttle costantly, the little 0 with a / in it is the average mpg that changes slower, the instant sees 200 then goes to - - -, it isnt that one or i'd be saying i get 200mpg average, if that was true i think they would be the most economical diesel car ever? if it was the instant and i was pulled over to take the pic, i would be reading - - - on idle. i do know what im talking about.
