boost problem i think

[wayne_gtiT]

talk about hijacking my thread 

does anyone know what could cause the boost problem, would a faulty maf cause it?

[topher]

Doubt it's the maf.. could be any number of things. You could go replacing every sensor one by one and still not get anywhere. Could also be a crack in something metal (manifold, turbo etc.) which expands and closes up when its nice and hot.
Did you say you were in Tamworth? You can either pop up to r-tech's workshop (hinckley) in the day or round to my place (dordon) one night in the week and i'll do a quick vagcom scan to see if there are any codes.. might just be something simple!

i dont thrash my car when its cold but i know theres a problem,any ideas of a solution to this, its definatley in limp mode till 90 temp, want it fixing before it gets worse, not really clued up on golfs so i dont know where to start

If it was limp mode the turbo wouldn't boosting at all, well the diesels dont

Petrol is the same

so its not limp mode then if he's getting 5psi

[wayne_gtiT]

yeah topher can pop round anyday thats best for you, im workin 11am to 8pm this week so next week might be better for you, ive just ordered a new stainless exhaust manifold so fingers crossed thats cracked but im pretty sure its electrical, how much are the remaps now?

[richw911]

Wouldn't have said so no

*shouts for toph*  

[topher]

you still get some boost.. dunno if it's as much as 5psi though

pm sent wayne

[wayne_gtiT]

i will hold 5psi all the way through the rev band, just went and tried, i waited till bout 70 degrees though, then all of a sudden it changes then will peak at 10psi and hold 7psi, if ought was cracked it would slowly taper off when gap closes, its got me stumped,ive done my own service and havent got it cleared yet would that be the problem?

[topher]

nope, wouldn't have thought so.

hall sender is a possibility though
