Engine power is getting cut *FIXED*

<< < (9/13) > >>

ktlstar:
bump.

Another 2nd gear pull, pretty much full throttle even though it does it without boost.

2nd coloumn of values is the fuel regulator, 7/8 is high fuel rail actual/specified.

heavyd:
I still think its the pump. the high pressure pump isnt getting enough fuel, so cant be that.
You can see in the 4th column, when the pressure drops, the fuel pressure regulator value is going to 4000 to try and get the fuel through.
Looks like you might have to spend teh money on a new pump if no one else is going to give you any ideas, unless you have a mate who will let you borrow his pump for 10mins.
Its only a  20 minute job to swap the in tank pump over, hardest part is getting the seats out

ktlstar:
Cheers Heavyd for some info mate,

I had the pump out today, yeah them bloody clips are a pain to get out!!

Anyway i got mine out and my mates normal gti but it looked different so i didnt risk it.

Went VW and they wanted £167 then he said something about the control module £93 ontop.

Do i need this control module ? I dont think i do.

Anyway a mate can get me a pump the same one VW quote me for around £100 from TPS which is not to bad!

I do think when i was cranking the engine over caused the failure.


So does 4000 mean its working 100% ?

These log are sent back to PDT @ Dave. Touch wood he can pinpoint the problem/

heavyd:
The value shouldn't get to 4000, like it is until it goes iffy. I didn't buy a regulator for mine.
Mine went dodgy after the garage put the camshaft in wrong. £100 is better than what I paid. You might have to try method of repair as looks like no one else is willing to give any decent advice :confused:
