Hi, so the thing is i spent time and money for the mechanic to fix my engine light, now there is no light but i think the power is missing plus i feel a spike in torque in the 1-2k rpm range, in 1 and 2nd gear

 

i fixed the boost leak

new afm

new N75

 

the car runs great now, but the lack of torque is baffling me

 

now after some googling i am thinking about these things that can be wrong

 

the cheap aftermarket re circ valve (007 clone) is acting up ?, before it had Forge Bov

the map sensor is bad ?

 

what other solutions can i check out ? im tired to throw cash at new sensors but nuthing changes..

first and cheap... change the dv for a standard one, see how that affects things.

Do that...and have you had it scanned? Bov are bad news usually in these as they are so dependent on air being metred correctly.

As Yellowcar stated. Get it scanned, & stick a standard DV on it.

BOV :thumbdown:

well i dont know about cheap, costs about 86 pounds at the dealer :s

 

but i changed my 007 ebay clone to the Forge bov wich the car came with, alot of diffrence, i feel more torque

 

now 2 questions ..

 

 

whats the diffrence, why does this make the car lose power having something like the cheap recirc valve, now i dont know if it was a wrong spring in the valve or what.

 

and should i spend the 86~ pounds for a new stock one ...

expensive in iceland..... have you not got second hand or e-bay ? £11 http://www.ebay.co.uk/itm/Skoda-Octavia-vRS-1-8T-AUQ-Turbo-Stock-Recirc-DV-dump-valve-/141950640176?fits=Model%3AOctavia|Cars+Type%3ARS+1.8+T&hash=item210ceae030:g:QhkAAOSwgyxWW4nv

Standard VAG DV is about £25 in the U.K.

hmm, i might try that, thanks

 

but do you guys know why it makes such a diffrence ? the stock one vs. ebay 007 clone that is ?

most after market dv 's are crap..... I have the forge 007p, and my car was loosing boost in waves when I bought it... my local mechanic said to look at the dv... I swopped for standard, and the fault went away....

 

I since serviced the forge item and replaced it.... and all is well.... think I may service it every time I service the car

 

a fair few people on here may recommend a standard item for this engine....
