Has anyone come across the fault I have at the moment with my scooby 2000 awd Turbo? I took it out today and it cuts out under hard accelaration but carries on going. so, managed to get it home. I suspect i might have somthing to do with the fact that I had a dump valve fitted which was faulty and a k+n induction kit which is fine. So I put my standard plastic dump valve back on it 2 days ago and it was fine after that until today.Does anyone have any ideas or is a computer diagnostic job!.
Thanks.Turbohot (hopfully not turbo knackered )

 

Sounds like it's over-boosting and hitting fuel cut. Do you have a boost guage?

 

No mate.Do you think it will be a case of going for diagnostic?

 

hi again i have booked it in for diagnostic check £65 + vat
i have heard that if you disconect the batterey it will reset the icu will this sort out the problem? or shall i just let the garage sort it out it seems a lot of cash just to find out what the problem is!!.

 

disconnect the battery for about an hour
see fi that cures it
mines disconected at the moment lol
ive just started running sum stronger doseage of octane booster and i want the ecu to learn it sharpish

 

Still sounds like it's over-boosting.

Do a search on Overboost for possible cures:

If I do disconnect the battery for an hr or so to in hope correct the fault,do you think it could f***k the immobiliser/alarm system up and then,even that might need re-setting?
Pls.suggest!

 

Thanx Drexel! And,Stickymicky,I did disconnect the battery for about an hr and connected it back.Of course,no f**k up with the alarm/immobiliser etc but tell you what,prob still exists,mate.
Any more ideas,keep them coming pls!

 

I agree on the overboosting and fuel cut. Wouldn't expect the ecu reset to do much for it in that respect. You wont know unless you fit a boost gauge though.

thanks its seems it may be overboosting any idea how it can be fixed by us or a garage? and will it need diagnostic check.
thanks Turbohot.
