traction control on,4th gear,35mph,gentle acceleration=headbutting the windscreen.
keeps cutting in as soon as i touch the throttle in 3rd or 4th
operates perfectly in 1st and 2nd
no faults found with vagcom or launch x431
tried various tyres,bridgestone's,yoko's.. still the same
we'v even plug'd the laptop in and altered the remap to bring the power down but it still does it,so power went back up as thats not the answer either.
tried everything,tyres,abs sensors,even fitted new drive flanges for new abs rings!!new driveshafts,wheelbearings,no fault codes.i own my own garage and we cant work it out.Anyone got any ideas please..This is my own car

Seems odd for it to not report any faults.. MAF sensor doesn't always throw up a code though, especially if it's an intermittent fault that only shows up when under heavy load. I heard of people using mercedes MAFs in the TDI's, not sure how they got on.. but deffo avoid the cheap copy ebay/gsf ones. VAG all the way.

hi dude,i had been thinking of the airflow sensor,styl the original one on,but have ran live data screens whilst driving but no tal tail signs.i've just been out in it and it was hasitating at around 2800rpm..never done this before but does sort of support poss airflow meter.
which merc is a good donor matee?

not really a diesel man but there's some info here http://www.geocities.com/tech4tdi/ but its not just a 'plug and go' swap.. they're about £20 less than you'd pay for an exchange unit from VW. Try running it with the MAF unplugged to force it to use default mass measurements.. if it still kangaroos in 3rd/4th its probably not the MAF. If it fixes the kangarooing (bare in mind with the maf unplugged you won't be making full power) then pop over to ventura and get an exchange.. bloke on parts desk is the only one I'll talk to in that dealer :lipsrsealed:

have you logged your actual air intake pressure??
do you get any smoke out of the back??
when i had a boost leaked the car kangarooed like no tomorrow and chucked lots of black smoke out

A few hours logging data and bypassing parts for trail and error solutions is the only way to go with problems like this.
If you get stuck let me know as we are only down the road from you.

hi guys,just to let you know no boost leaks,un-plugged maf ages ago and it drove it.was slow,but still the traction control was going mad,even when you lift your foot back off the throttle.you either wait for revs to drop back down to 1000rpm or turn it off.it's driving me mad.
im a mobile mechanic,im best mates with james form bhpremaps.com (he owns the mk1 with 2x1.8 20vt,featured in performance vw & maxpower)
all his work is top notch,re-maps perfect.inported original software to try it,and it was worse!!so in whet the modified software again.
i,v been trying all day agen with it,i use trade parts services in aston,genuien vag parts at a quarter of the cost,cheques are even payable to volkswagengroup uk so all parts ever change are genuine.i'v checked all pipes,even tiny vacccum pipes,no air leaks anywhere.
i'm starting to wonder if it could be to do with the diff,could it be starting to fail,but i'v been told by many people the 6sp is bullit proof.no unusal noises anywhere
-
just another kwik one,only smoke is on cold start up for about 5-6seconds
-
this is for nick at r-tec.
i see how we get on but i think i might just have to pop up one day
-
quick question - are you running a hybrid turbo to be running 200bhp?? :undecided:
-
no hybrid mate,no need.original turbos will run 1.1bar all day long with no probs.standard injectors will run upto around 230bhp.around 205bhp is the max you can run the standard turbo system,but even then its the intercooler that restrics you before the turbo will.but the art of quality re-mapping mate is not just fuel&turbo,write the correct file and the engine does most the work not the turbo.
once i'v sorted the traction control its going upto midlandvw for rolling road printouts,then after that on goes a bmw330D Garrett variablevein turbo,rad-tec custom frontmount intercooler,custom silicone hoses,fratteli 520+injectots,james will re-write the software again,the a trip to jodie at midlandvw,get it on the rollers and should drive away with a printout for around 275/280bhp.
I'v got some videos to try n put on display somewhere of the golf pulling dead strong from 0 to 150mph..
if you want i'l post the date when im going up there so you can come and witness it for your self.
my golf is erm well known in tamworth for being abit rapid,people must have seen it.5door,in antherthite,did have 18"rs4's,now on black and silver 17" bbs's,droped on it arse,gti badges and it's 02 plate,dnt smoke and im out in it most nights

Doesn't ring any bells chap, what colour is it?

hi guys,
Update on the traction fault..
i put standard 15" alloys back on,traction goes crazy!!light flashing 1st,2nd,3rd,4th&5th but only traveling at upto 45mph!!traction took over,killed all power,turned it off,carried on driving spins up 1st,2nd,3rd but not 4th or 5th so why is the light going..
borrowed two audi tt 18" alloys of me mate tt for 5mins,traction control on,drive as normal 1st,2nd,3rd,4th,5th,6th no lights flashing,no bogging down,no power lose just pull,pull,pull..
i tried all diffrent brands of 17"tyres to start with,bridgestones,yoko's,michelins it was still the same,but 18"s with budget tyres and no faults!!!
so the only explanation i can give is the traction system has got to have been getting confused and i need bigger wheels..i need 18"s again..but there goes the handleing!
any one out there runnig 19"s??how does it handle??
and the colour antherthite met(dark grey)

If you've a hardware issue then the best way is put it to stock first and eliminate this first so the mapping can be removed from the equation, after that then start to look at the mapping, hard to say without seeing the current map running but I have an idea.
-
hi john,
all mapping was done by james bowman, bhpremaps.com,we did import the original file back in but this didnt seem to cure anything but make it worse realy.
it's just realy strange that it doesnt play up at all with 18" on, it come with 15"s as standard so i cant even work out why this would be an issue.
i must admit, as this is first car that bhp have re-mapped of mine,power and economy as been fantastic for 40,000miles,
now its only returning 37.6mpg driving it so easy,it has droped as low as 31.3mpg!!this was monday morning,did drive fast but not that hard.
car has covered 104.457miles now,i think it might be expensive to cure this one for some reason.
it is due a cambelt,doing this tomoz,next week me and james are heading over to the rolling road to see what we can find out cus it realy is driving me crazy and stressing me out now lol

think we have solved the problem, will be heading to DNA tuning in january :smiley: :smiley:

think we have solved the problem, will be heading to DNA tuning in january :smiley: :smiley:
so what was wrong with it?
-
We're going to investigate properly and report back :)
-
So what was wrong with it! :shocked:
-
We haven't looked yet, will be in the new year :smiley:
-
hi guys, update on the golf, we never got chance to cure the problem, anyone ever seen a pd with a con-rod thru the block?, we'l i own one!!,only done 108k as well!!!!!!!!!
if anyone wants parts, the golf is being broken for spares.coilovers and wheels and interior have gone, all good panels aval in anthathite met,6sp box
i would strongly advise that you dont try and run the power this was, i believe the software screwed it all up for me.
byesybye ive converted to something that can cope with pure power
-
Personally i just have traction control off all the time :wink:
