Spluttering, limp mode, drinking petrol!

[D10RDE99]

can any please shed some light on my problem

mk3 ibiza cupra, st1 revo'd,forge dv, fmic, twister induction kit,

few days ago whilst drivin on the motorway aprox 60 - 70 mph my car ( 2001 ibiza cupra) started to splutter and normally peaks at 18 psi now only gets to 5 psi, triple checked pipes and found no leaks anywhere, quite a bit of white smoke/steam coming from exhaust even at idle, altho it does smell like petrol and has left a black mark on the drive under the tailpipe, been to the local garage and they say its the cat, oh and the car is drinkin petrol like its goin out of fasion

thought i'd ask you guys that you thought as you seem to know more about these cars the the local grease monkey

so

1, is it possibly the cat
2, wheres the best/cheapest place to get one


many thanks in advance

IIRC you should smell rotton eggs if cat

usual checks are MAF, coils, plugs

someone else may give other suggestions

oh, and run VAG COM

sounds like a maf if its not boosting right and its drinking fuel

xxxxxxxxxxxxxxxxxxxxxxxxx

would the faulty maf cause it to over fuel enough to leave black marks on the floor tho, if i unplug the maf and take it round the block will it drive normally (if it is the maf thats faulty obviously )

just unplugged maf and took for a spin (approx 1.5 miles) felt much smoother and more responsive up until i hit 5 psi of boost and then its like hittin a brick wall

oh and its cuttin out if i dip the clutch for more than 3 seconds, and strugglin to keep runnin at idle

help needed

have you got vagcom mate worth pluging it in?

it'll be in limp mode. will have to run vag-com on it and see what faults it brings up.

alternatively, and at your own risk. you can disconnect the ground cable on the battery for half an hour, and that will clear the faults. you can then run your car with the maf disconnected and see if thats at fault. and then reconnect it. but i would only do this as a last option to test the maf.

there will be a reason why its in limp mode so i would see if there is anyone in your area with vag-com first

i haven't got vag com, how much will a garage charge me to vag com it cause startin to annoy me now,

Not true btw. rotten egg smell is unburnt fuel in your cat. Usually pointing towards a faulty coilpack or spark so 1 specific cylider isn't firing.

If all else fails you can take it to midland vw in cannock, he charges 15 quid to plug it in, tell you what the fault is and then delete any if necessary. Not bad really. Ive got a lead but just cant get it to work. Ollie where abouts are you just out of curiousity?
