Rolling Road.....disapointing results..

[duncan]

have got the car booked into VW eastbourne (where my mum lives) i use a good VW in surrey who so far have been great!

only problem with them is that they cant see the car till Tuesday next week so am going to try the eastbourne VW.....

what do you think i should say to them - ideally i dont want them to mess with the map and hope its just an easy fix

im guessing that if it is a boost leak or a faulty MAF then this should be easily diagnosed and fixed?

Note that VW dealers dont call the diverter valve by the same name. Someone will come along soon to confirm the name that they know it by... I've forgotten lol!

hi duncan
sorry to hear about your issues, sorted soon i hope.
I remember about a year or more ago, i was on the look out for a candy more door and spotted one for sale that had the ''WALD'' badge on the hatch, i asked over the phone with them what it was but they couldnt tell me much. it was also an import so i didnt move on it, it was also a bit out of my price range.
i then went for a test drive of a demo car (std) at corkhills liverpool, and asked about one id seen with WALD badge, he had heard of this mod and said the same as you being a conversion done at factory.
keep us info'd on this

duncan , Id stick with the VW dealer you know are mod friendly.
I can understand you wanting to keep the remap too.
The car stores any engine fault codes when issues occur which the dealer look at first, and you should have plenty !
Im surprised you dont have a yellow engine light up on the dash tbh

Good luck and yes itll soon be fixed

yea, to be honest when speaking to my local VW dealer they were also supprised that there were no warning lights on the dash.  im guessing when people have had diverter valves go they probably did have warning lights.  is a bit of a worry...

another thing is that i havnt noticed a big power drop and when the car went in to get the coil packs replaced a week ago there were no warnings on the diagnostic tests that they did.

i feel like this is a problem with the car from when i bought it otherwise im sure i would have noticed a drop of nearly 60bhp and around 60lb/ft of torque.

this leads me to belive that it might not be the easy fix and will not be supprised at all when the garage phone me up tomorrow afternoon and say they cant find a fault...

but one thing is for sure they need to sort out why its running so rich becuase my guess is that both the problems must be link.  a drop in power and the car running rich cant be a coincedence can it?

[duncan]

UPDATE FROM VW:

spoke to eastbourne VW who were helpful -

they said that after running a diagnostic they cant seem to find any faults, they also were scratching their heads about this wald conversion which to be honest so am I

i asked them if they could really try and find a boost leak if not then the only way to find out why its running rich is to do a full ECU flash back to standard then start looking again..

annoying really since ill now have to fork out for a new remap at some point but then at least i know its done propperly.

will probably go to JKM when i have some spare cash....

fingers crossed its a simple boost leak and that will return the car to 240bhp but somehow i doubt it.

they also said that they did tests on the mass air filter and that wasnt throwing up anything strange..

will update again once VW have got back to me

[WhiteGTI]

I wonder if its something simple like the map is corrupted??

If the dealer ran a diagnostics and found no mechanical reason why the car is mis-peforming, then maybe the ECU is confused/map is corrupt!

It will be interesting to hear what others who are more experienced in this field think of this when they see this topic

hey duncan, i havnt read the whole thred so people probably already said the DV.

mine ran 183bhp on my first ever session after a re-map. it was just split hoses on my DV. if the cars down on power, blame the dv, 99% of the time thats the case!

[VC]

if it's not DV bin the map?

[duncan]

if it's not DV bin the map?

thats the plan, but if it was the DV wouldnt that be throwing up engine managment lights and also showing up errors when VW run a diagnostic?

they said that there were no faults when running the diagnostic..

also i do want them to check if it is the DV what could it also be know as?

[john_o]

tbh the dealer should do more than just check fault codes , but also log boost pressure etc if theres a suspected issue.
However Im not surprised they havent.

From here on in I could see your choices as

1. Keep WALD and try and find a local VAGCOM owner who knows what they are doing to log some useful info , boost etc
2. Reflash ECU to std , although im not sure this is gonna help if the VW dealer isnt willing to delve deeper  as youre problem may persist after that and then what they gonna do?
3. Just bite the bullet,  phone JKM (prebook) take a day off and say they have a day to fix. (how far is it for you?)

Can you get your AF logs + dyno graph up so we can see its profile?

1 or 3 at this stage  

[joesgti]

tbh, if this happend to me id jack the car up, take the DV off, look at it, take it apart, put it back on and notice the difference. if there is no difference then get a diagnostices session at a trusty garage. where abouts are you located?

you can take the dv off in 20 mins. 

[WhiteGTI]

Is Croydon nearer to you than JKM Duncan?

Tuningwerkes are also very good with this sort of thing.

[duncan]

am located in either east sussex or surrey.

after speaking to the garage earlier they did say they would investigate the posiblity of a boost leak more thoroughly.....

am waiting to hear back from them - otherwise will save up for JKM..

am really hoping they just find a boost leak but something tells me they wont....

[joesgti]

how does the car sound when pressing on?

can you hear a wOOOOOOOSH?
