VW Specialist couldn't fix my car... PLEASE HELP!!

[barrym381]

Hahaha I have don't worry! I don't have time to have a go at it till this weekend, I shall let you know what happens! Reckon it's worth unplugging it and giving it a run without the maf and see if there's any difference?

try it see what happens  an give vw a call about the coil packs your car might be due some free 1s

Has a different MAP sensor been tried at all?

Might be wrong on this one but issnt 17705 an issue with a bug in the ECU software that causes fault code even though no boost leaks?

As has already been suggested, ring VW to see if the car is eligible for free coil packs under the recall - even if the garage claims they aren't at fault new ones won't do any harm.

Definitely try running it with the MAF unplugged, they are very prone to failure and can cause the symptoms you have described.

If the MAF is at fault then make sure you get the replacement directly from VW, non-genuine ones are prone to failing prematurely.

Clean it first with electric contact cleaner, 1.99 off the bay, cleaned mine Sunday as was revving erratically and boost gauge jumped to 0 and then back to normal constantly. Since then there has been no issues. Also that boost leak code was solved by niño by replacing all his vac pipes and fitting the forge 007p with free repair kit from forge and he doesn't have it anymore

Yip, took me a crap load to fix my 17705, I don't know exactly what fixed it but i replaced the following...

* Changed the charge pipe for an AGU one, (Mine was AUM).
* Changed every single boost pipe to silicone.
* Changed DV to forge 007p & fitted a revised piston.
* Change TIP (Turbo inlet pipe) to silicone.
* Changed Rocker cover gasket.
* Changed Inlet manifold gasket.
* Did an N249 bypass.
* Changed Injector seals.
* Changed Injector seats for the Seat white revised ones.

Then and only then did my 17705 go away

get some elctro spray to clear out the maf sensor, advise changing all boost pipes regardless of what they say, coil pack check etc, may be worth while changing you DV too

So I've given it a good old clean, put it back but where I've disconnected the battery and it's cleared the fault.. The bastard won't run. I completely forgot the garage told me it literally shuts down if the fault is cleared. Any ideas?? I'm at the end of my tether with this f**king this.

Anyone is manchester with VAGCOM that could help me??

[GTi_James]

That shouldn't have happened tbh, you didn't move any of the fuses and you removed the negative first when disconnecting your battery?

 try midland vw they are a sponsor on here they are the dogs balls they will sort the problem if they cant then no one can... also when you start the car do you get a sharp rattle noise??  as my cupra did what yours was doing and it was the chain tensioner was weak and telling the ecu to shut down?

John Jeffers at JVW Leigh, might be abit out of the way but he's a top guy 

[Dalo Harkin]

I don't have full vagcom but I can check it over for you, I'm only in Stockport and can read and clear faults for you
