My cupra isnt boosting

[PhilW]

I think MAF first, low g/s even if in limp mode is really low.

Have you tried clearing the codes and disconnectin the maf for a run to see if it runs a bit better?

I can clear the codes for you tomorrow if you want mate.

 

[DaNnY_LaD]

Should i do that then clear the codes then take it for a drive see how it is?

Then if any codes come back sort it out that way?

In your haste to fix your car your not listening to everyone Danny. Unplugging your MAF does not always tell you if it is knackered. Start here and get a genuine bosch one. Lambda could be a problem but changing all these things will cost you the best part of £300 and some of them may be totally good parts and changing them could mess it up more. N75 dont tend to fail and people only usually change thm to gain performance. One of those faults could be the secondary air injection system aswell but ignore for the moment as most of those faults can be caused by one part failing. Only get genuine parts for the things people have mentioned and not from ebay because they may not cure your problems.

No i said MAP sensor, not the MAF (MANIFOLD PRESSURE SENSOR)

i am listening mate...Otherwise i wouldnt of asked for help..

ive found a website called vagparts and they have mafs on there for 100quid bosch ones..
But i cant find the code on there to match my engine type AYP or the part number i got from the search..

Go to gsf. They are £65 one exchange and they are bosch ones. Or call alex at TTS as he can do them priced similarly.

 

[DaNnY_LaD]

Gsf?

they got a website or number?

will pm alex now..

received my new cts this morning and will order a new maf and clear all the faults..

Edit: looking at there website..

 

[DaNnY_LaD]

i cant find the seat maf on there...

 

[pj1985]

Part number is 06A906461D I think.

 

[DaNnY_LaD]

before i order one should i try another maf of a another cupra?

 

[Big_daddy]

Best to ring them up, gsf website dont have most of the parts listed for the seats

 

[DaNnY_LaD]

Well erm this was weird..

Had a little trip round to adams tonight to clear all the fault codes...On the way there the car was the same no boost at all...

He then cleared all my faults/codes correctly via vagcom then i left soon as i started the car the gas pedal was really light..So then set off then heard the induction kit and dv so i was shocked..

I then turned out of his street and i had boost in every gear till 4.5krpm then goes straight in to limp mode..
So i turned it off then i had boost again till 4.5krpm so i have boost till i get that rpm range...

Never did this before ...

So gonna drive it abit then do another log/scan and see what comes up...

 

[DaNnY_LaD]

right im gonna do another log 2day what codes do i have to do ect and actual vs request

 

[Big_daddy]

here are the main ones i do.

003 + 020 air flow + timming
115 + 031
118 + 032

you may want to do 14 as well to check the duty.

 

[PhilW]

Dont bother with 031.

114 as well.

So n75? Acuator?

Its showing just over 1bar on my boost gauge..
No isnt that around 13-14psi?

My cars a non mapped cupra?

 

[__B3NNY__]

You havent played about with your actuator have you?

If it turns out that its the N75 i have a std one here you can have for a couple of beer tokens.
