Scan for faults... clutching at straws else especially as you haven't specified any symptoms....

<tuffty/>
 
Cheers tuffty, Iv not got any noticeable symptoms that I have felt, boost seems fine and its not in limp mode. Im going to try and get it scanned today so il update soon as.

Thanks Chris.
 
Hi got it scanned by (lewis583) cheers James. Code that came up is 17704 - Error in Mapped Cooling System (usually temp Sensor or Thermostat) need to get it sorted asap before AITP hope it wont be expensive.
 
Anyone know a rough cost I would be looking at to get a new Temp sensor and Thermostat fitted.

Thanks Chris.
 
Really wow thats a relief, cheers Dave I was expecting over £100 just need to get it booked in, I have seen the guide to doing it myself but im useless with working on cars lol
 
Get yourself to Midland VW mate, they will be able to get it sorted for you.

Yeah im going to ring jody in the morning hope he can sort me a good price he has been good to me so hopefully his price wont hurt my wallet lol
 
Well its going to Jody at (Midland VW) £80 all in, so touch wood it will be fine for AITP. I'll let you know if it solves the problem.

Thanks Chris.
 
Have you explained the issue to him, if not, have a word and see if he knows what it is thats causing the issue.

Lol that would probably be a good idea, il have a word in the morning I hope im not opening a can of worms, last time I had engine problems on my old one it turned into a nightmare running rich, misfiring on cylinder 3, injector exploding and ended up costing me over £1000, fingers crossed for just the sensors.
 
That fault is 99% related to a duff coolant temp sensor. Buy a genuine green one from Audi/VW/TPS /Seat, & change your self for £34

Hi really, thats put a different view to it, is it that common then for that to fail. How easy is it to change I have minimal to no mechanic knowledge.

Thanks Chris.

Chris its easy peasy,I've done mine so we could hook up and I'll do it for you
 
TBH in my experience the Thermostat is more likely than the CTS.

You can often tell simply by how the temperature gauge behaves. Thermostat will allow the engine to run cool, ie the guage will never get to 90c, until your stuck in traffic or sat idling on the drive. If the guage often sits below 90, and climbs if left idling for 10mins, then i'd be changing the thermostat first.

If the guage quickly comes up to 90c and never moves, then its more likely engine side of the CTS is faulty.
 
thermostat is quite an easy job. Would give it a go yourself if you have a load of extension bars. 30-45 mins if you have done one before, bit longer if not. Just awkward to get to. Temp sensor is 5 min job :)
 
just check comparitive temps in vagcom before condemming the thermostat.
in the CTS there are 2 senders, one for instruments one for ecu..
look at both temps (engine + instruments) when its warmed up and confirm they're the same) If they are, its unlikely to be CTS.. If your temp wavers about or does'nt get to 90, or rises and falls from 90, as confirmed by the engine + instruments reading then it is thermostat

CTS is the cheaper of the 2 to swap out.

Thanks Bill, yeah your right it was showing 90 on the dash but 60-70 on VAG-COM, when left idling still showed 90 but was at 97-99 on the scan. hopefully It will be sorted for AITP now :salute:
 
Hi all got the car back from Midland VW today all sorted. Thanks for all your replies it was the Thermostat and I also got the Temp Sensor changed while it was there

Cheers all.

Chris.
