boost issues.

[LEE69]

There is a rubber ring, that just pulls back.See if there is oil there.

hi mate just a quicky do you mean i have to take the manifold off?


iv just had a quick peek and yes there is oil all around it???

 

[LEE69]

No just remove the nuts and 5mm allen bolts, it then lifts off the dipstick and gives you more room to see.

 

[Cupra-jb]

ok mate i already removed that on saturday when i replaced the pipe from the manni to the fpr as it was split,but yes there is oil around that valve.

but if its broken wouldnt the car just not boost properley all the time?

as some times its ok then others its not?


thanks for the help lee.

 

[LEE69]

No idea mate tbh, mines obviously leaking/blocked so I'm going to replace it anyway.

 

[adam cupra 20vt]

How much are they Lee?

Worth replacing for peace of mind.

 

[LEE69]

Waiting on a price coming back mate

I would as it is a filter, and can get blocked.But if you have no issues, don't bother.

 

[adam cupra 20vt]

Well if its cheap enough I'll fit one anyway when I change the manifold......sods law says if I dont it will fail after and be more work

£11.74 from Here

Far easy to remove the one of the manifold then the one to the fixed pipe, then do it away from the car

iv just run my mates vag scanner on my car and found these codes.

1.17705,p1297 connection charger to thrrotlevalve/pressure dropped.

2.17535,p1127 bank 1 mixture adaptation (mult)system too rich

3. 18010,p1602 power suppley b+ terminal 30 low voltage


any help on where these problems are and how to check/fix would be great guys.

thanks.jamie.

 

[adam cupra 20vt]

Have you cleared these codes then taken it for another drive? They could be years old and nothing to do with it.

I'd clear them, take it for a good drive then read it again.

 

[Cupra-jb]

yep i cleared them and went out for around 30 mins and only the first one returned.?

17705/P1297/004759 - Pressure Drop between Turbo and Throttle Valve (check D.V.!)
Possible Symptoms

* Power Loss

Possible Causes

* Leaking hoses and/or pipes between components
* Check Boost Pressure Control Valve (N249)

Possible Solutions

* Check hoses and/or pipes between components
* Check / Replace Boost Pressure Control Valve (N249)
* Check / clean Throttle Valve, do Throttle Body Alignment

 

[Cupra-jb]

thanks for that adam,

iv bypassed the n249 so i dont think this could be causing the problem?

is there a way i could clean the tb without doing an alignment as i dont have vag com to do it?

cheers.

 

[adam cupra 20vt]

I guess you could remove the hose and spray some cleaner into it and give it quick clean whilst still on the car?

Could try using the N249 again to see if it helps?

Its not the DV failing as it gets hot is it? [could that actually happen??] you could try the standard one again?

 

[Cupra-jb]

ye i might try putting the n249 back and see if that helps.

i dont think its the dv gettin hot as i went out in it this morning and as soon as i set of there was v,little boost.


any more ideas anyone?

thanks.

[Cupra-jb]

iv put the n249 back to how it was but that didnt help?

iv just removed my turbosmart dv and done the pen test and as soon as i remove the pen it just drops back down,so does this mean its kaput?

even though it still makes a noise when its on the car?

cheers guys.jamie.

 

[adam cupra 20vt]

I have no idea....can't you try the standard one?

 

[Cupra-jb]

right been out in the car today with my mate we drove around 60 miles and for the first 20-30 miles all was fine great boost e.t.c,

then for the rest of the journey it went again i think its in limp mode.

i scanned it again and got the same codes so cleared them and they come straight back.

iv checked all the pipes i can get to and the dv and they all seem ok,im going to put it on a ramp on saturday,so is there any certain bits to check,as im gettin really p****d off with it now as you never no when you get in it if its going to work or not


cheers lads.
