hi m8. based in coventry. it feels lyke it strugggles to get to 30mph then the cars fine, its got all the poer i need. but on the motorways sometimes when i hit 80, it feels as if sumthing jus cuts out and wnt go past 80. som1 sed it mite be a air flow sensor

try unplugging it to see if there is any improvement. it is quite a common issue and an easy fix................ its just annoying when it happens!

same exact thing happend to me once, except i was driving at very excessive speeds on my way to stoke on trent at night (was in rush) cars ECU thought the turbo had fault as it was running full for about an 1.5 hours it switched into limp mode... scared **** outa me. felt like i'd run outa fule .. then realised that my turbo was being by-passed and that my company van was quicker than my car!!! any way never happend again ater that for me however maybe you do actually have a fault and your car switches to limp mode. whats it like after an engine switch off and on agian?

the 90 bhp only has a top speed of 99mph doesnt it?

 

[stuart86]

take the hand brake off!!

unplug the MAF sensor, see how it goes. its a dead common problem so if you need help with that have a search back through the TDI section.

The only way to tell for sure is to get vag com on a laptop and log the MAF, if thats ok then i would log the boost. I presume you havent got loads of smoke coming out the back?

 

[FR-RUSH]

thats right that the turbo doesnt kick in untill 3000 revs, thats the case with all derv turbos isnt it?

you have to ride the turbo to get performance out of it.

im sure your local stealer would easly plug it in and tell you if there are any faults.

 

[sssstew]

nope, turbo kicks in at 2k rpm, just before often.

even the lower powered tdis will easily do 90 all day and pull from there.

 

[skahigh]

what measuring block is needed for the MAF? I noticed DPJ has logged this and wanted to do it myself....

 

[sssstew]

block 3

cheers

 

[skahigh]

is it different for 1.8T petrol?

 

[Molehill_Mike]

1.8T blocks are different

002
010
115
and 118 are most commonly used with the 1.8Ts.... not 100% sure which is which, but out of those you have MAF, Timing, Intake Temps, and boost...

Back to the question about when the turbo, mine kicks in at 1500 revs is that about right? or is that early?

 

[BCM]

between that and 2k sound about right!

 

[Molehill_Mike]

Yeah mine comes in from abotu 1500, or feels it lol

For the guy who thinks his 110 is slow.. see this thread http://www.seatcupra.net/forums/showthread.php?t=143029
