car has good moments and bad moments

[jason-jm]

It doesnt seem to be pulling like its 200bhp+

first is fine, second can have a bit of a delay and then it kicks in and all the other gears are the same,

comes to a stand still then kicks...

what could be causing this?

It also doesnt seem to want to exceed 120ish (private track) my saxo was only 130bhp and it used to reach those sort of speeds with ease...


something is isnt right as Everyone elses seems to be awesome at 200bhp

Get it on vagcom, that will show up any faults if any

 

[Daz_gibbo]

Suspect you have one of the many common faults on these cars, nothing heavy.

 

[jason-jm]

Im going to put the standard DV on later and see if that does anything..

I am right in saying the car shouldnt be delaying and then shooting off then delaying then shooting off in all the gears should it

Id need to go to a vag garage yes?

 

[Beaker™]

As said, get it on VagCom. I've had sililar hesitation issues in the past. Could be your MAF or coilpack playing up.

Best to find somone local who has it, a garage will be expensive. Try posting in the vagcom section to see if anyones local to you.

 

[jason-jm]

How much is it for a new MAF..

Im not sure where the nearest Vag garage is (being in mid wales its bound to be 100miles)

 

[Beaker™]

Around £70 + your old one at any VAG garage. Try unplugging it and going for a spin. If it drives better with it unplugged then thats more than likely your problem. If it drives the same then its probably something else.

 

[jason-jm]

it wont do no harm to the car unplugging the MAF no?

 

[Beaker™]

No, the ECU will run on a preset MAF reading, it'll be fine, unplug it and give it a good ragging. Although i wouldnt drive it for more than a few days unplugged though.

 

[jason-jm]

No il only try it for 10-20mins see if its any different..

dont get me wrong when it pulls it pulls hard, but it doesnt feel much quicker than my saxo vts at times

when you boot it through the gears mate are you sure the TC light doesnt come on???

Now thats a good point, could well be TCS kicking in. Indicated by a flashing orange light on the dash.

 

[big eck]

When it first happened to me I thought I broke the car

 

[jason-jm]

Now thats a good point, could well be TCS kicking in. Indicated by a flashing orange light on the dash.

but i mean its sluggish at high speeds too

 

[Beaker™]

You tried driving with the MAF unplugged yet? Also, what map is it running?

 

[jason-jm]

just got home off work beak, need to be back by 12.30 so Im going to try now...

also I read somewhere about the maf being faulty makes the mpg etc go crazy, mine shows up at 70-100mpg sometimes...

just jumps randomly from like 40-70 - 20 etc etc

sound like maf?

 

[Ricardo_Smooth]

that will be the realtime mpg (not really much point having it on that) the average mpg is the one to look at so its prob nothing to do with it

Lol why's it showing up like 140mpg on the realtime one?


the average is showing about 23-26

I couldn't take the maff off I didnt realise it needed torx to take it off, il have to give it a go later...

If its the maf thats faulty will the car run well with a smooth constant boost rather than the short blasts?
