[DaNnY_LaD]

16500: Coolent temp sensor has gone £13 easy fix.

17832: Do you have a induction kit fitted?

16514: Check wiring, replace sensor.

18010: I assume you have had the battery disconnected?

16486: Unplugged the maf?

Clear the faults and see what comes back.

17832: yeah i have a Pipercross open cone induction kit

18010: yeah i discounnected it a few weeks back as i got an eml light so i just cleared it..hasnt come back since..

16514:How much is a new sensor and were abouts is it?

16486: i unplugged the maf last night to see if that was the problem and it was still the same..

EDIT:

Is this the CTS i need?

[__B3NNY__]

To be hones then you could proberly scrap most of those codes that i have listed bare the lambda, Ill try and find a pic of where the temp sensor is, im sure i only paid about £13 for mind and took 2 minutes to fit.

Wait for sombody to confirm this but your shot lambda sensor could be making your car run rich/lean and causing it to over boost.

could be wrong as im still pretty new to vag-com myself.

 

[DaNnY_LaD]

Well ive been gettin around 40miles to a 10er that to an empty tank aswell and no on boost at all as it aint been working...

Tbh im gonna replace the CTS and lambda as thats the only to codes that came up..
also that link i posted to ebay is that the sensor i need>

im pretty sure thats the same as the one i got. Best bet would be to get the part number and match it. Id happily pop out and get you the number you need but its pi$$ing down atm

 

[DaNnY_LaD]

not to worry i aint in no rush mate...Just wait till you get a sec...

So the CTS and lambda will cause me my boost issues?

 

[__B3NNY__]

Lambda is my main suspect, CTS shouldnt cause you any troubles.

 

[DaNnY_LaD]

so how much is a lambda sensor?

 

[__B3NNY__]

Around the £80/£90 mark i think?

 

[DaNnY_LaD]

were can i get one from and is it simple to replace?

 

[DaNnY_LaD]

Right so im lookin at around 100quid posted for a lambda sensor and the CTS is 15quid posted...

And my lambda is defo gone and were abouts is it?
As il check the wiring be i get a new one..

As my car does some time boost to 3k then it will stop and not boost at all

also could it be my N75 ?
