oh right ok mate i'll get the cts off ebay and the termostat from stealers. The thermostate that awesome have is that the right one do you know?

theres a link to it just above
 
Yeah looks right one although that one opens at a lower temp than the standard, that one would have been better for me but I didn't know they done one :blink:
 
ha ha ha sweet thankyou for your help, am ordering the febi cts you said from ebay and will get the other thing from awesome.

Cheers again.
 
Just to throw in my tuppence worth - I've been getting the same issue: temp gauge drops as soon as I'm going down hill. LEE69 on here told me it was probably the thermostat which seems to be confirmed here (especially as I spent £27 on a genuine CTS to replace what was probably a perfectly good one :()

In my old LC it caused the engine to run rich and numerous engine management lights but none so far this time (been 2-3 months without any drop in mpg or performance) so I haven't been too fussed about sorting it). Slightly concerning that it may result in coolant going round the radiator constantly - is it something that I really should get fixed? It's going in for an MOT tomorrow so might ask them to have a look

Thermostat! excatly what mine did, up and down hills and accelerating and breaking hard.

Its worth getting sorted I'm sure my MPG has gone up since changing it.
 
MPG on mine has deffo got worse recently. only managed 250 out of a full tank, would normally get 300ish.

luckily its in for its service tomorrow so i'll see what vag com brings up.
 
confirmed by JBS faulty thermostat :(

B@llocks! could do without extra expense before crimbo.
 
I've had to let them supply and fit it as I have no time to do it myself before xmas.

its not too expensive tbh but on top of the cost of service i could of done without it before crimbo. Bloody cars!
 
Hmm, any guides for changing the thermostat?

Is it in the Golf haynes?

Wondering now if it is my thermostat and not my CTS. Mine has been triggering the engine light with a code for failed cooling system (which ever code it is that points to 'stat or g62)

Mine has been sitting at a steady 70 degrees lately rather than the eratic temp posted here. I checked on VAG-COM the first time it threw the engine light and all the temsp were consistant at ~90 so i'll have another look.

I know we can't post any eBay links but are there any specific sellers with better or proven good CTS units? Don't want to go fitting something that's come from LIDLs :p
 
My mate ran a "Race" thermostat (basically a a cooler thermostat) in his 486bhp GT4 - basically if you're running big horsepower it'll open the thermostat earlier and cool the engine a bit more, cooler cylinder walls etc can hep to prevent knock., but his was running DTA Pro stand alone engine management so it was all mapped accordingly.

The ECU in the LCR however is set to operate within a specific operating temp (obviously there's margins) but if you run a colder thermostat it may end up worse than having a sticky thermostat... running rich, which can end up knackering your cat etc...
 
my gauge has just started going abit dolally but when check coolant temprature on the climate control display it still stays at 90 even though dash gauge is bit up and down but never above 90.
still dodgy thermostat even though doesnt change on digital display??
 
was going to go get one and give me something to do, then remembered what day it is and nothings open.
did CTS about 3years ago (green one) could it be dead again already?
