40k Service and NOT Pulling the Same!

[edmong]

Hi All, I had a 40k service done by an independant on Saturday. I supplied the oil (Mobil 1 5w30) and plugs (NGK Iridium) and they supplied the rest. I also had my Forge TIP fitted too. Now since getting the car back I have done just over 200 miles and it does not feel like its pulling like it was before the service.

Obviously it'll take a while for the car to 'run in' with the new plugs and oil but surely not this long?

I have a K&N 57i which I have not yet cleaned only because it does not look like it needs it.

Any suggestions why it feels slower than previously? Can't be the TIP can it? Any help would be appreciated.

ok sounds like your running same as me spec wise and power wise!! in your mod sentance!!
MAF is my first place i would look mine did the same felt like it was getting slower and slower!! until i changed it, with my maf being faulty i had no vag codes wich was strange, but they soon followed!! so check this and let me know chap!!!

other wise im thinking very faint boost leak,have you got a boost gauge?
also run the lcr up to 70mph in 3rd and hold it there for 20secs?!!!
my lcr would pink/miss fire, some times i wouldnt notice other times i would!!

and last of all get iy back on the rolling road this will help to show if you have lost power!! thats how they found my faulty maf!!!!

good luck let me know!!!!!!!!!!!!!!!!!!!!

No running in is needed at all mate.

Got vag com at all?

 

[edmong]

Yeah got vagcom but shareware version. I'll get it on tomor and see if there is a code coming up.

Have they fitted tip properly?any loose vacumm hoses??

 

[CupraMVR]

they pluged all the connectors back in?

maybe they missed 1 off or the hose on the tip not on fully and its popped off

 

[billyhas]

Definatley check all connections on the tip.From the work carried out this is the only place where a power loss could occur.

 

[edmong]

Its still pulling hard just not as hard as before the service. I'll get vagcom on tonight and check codes. I helped fit the TIP so all the connections should be ok but i'll check.

Could the car be refusing the plugs?

 

[andycupra]

oil / plugs dont need running it.

id suspect the TIP. loose hose etc. Although the maf is a possibility seeing its int he same area and may have been man handled..
try unplugging it. - does the car run ok then?

something to consider. spoke to dealer recently about remaps and theyre pretty sure that most places will download and update your ecu which wipes remapping

Thats simply not true, its certainly not something done 'routinely'. Its a very very rare requirement to do this.

Right its still not running the same. I'll vagcom it later but I have noticed something on the TIP.

Where the N75 valve goes the tubing to it is much longer on the Forge TIP compared to the original. Is it worth me cutting it down?
