Picked her up today and drove back to Liverpool from Bath. Sweet as a nut, drive back was great, reminded me how well the 1.8T feels and was a welcome back from driving dirty old dervs for the last few months.

Just been out for a spin with the missus and opened up the car on a dual carriage way. Noticed straight away there was a lack of power - followed by the engine temp gauge shooting up to 130c - and 'Check coolant' followed by 'Engine Workshop' flashing up on the MFD.

Managed to limp home keeping the temp gauge at about 110c.

Hooked up VAG COM and its not reporting any DTC's [:S]

I know the loss of power is the ECU pulling back and going into soft limp due to the increase in temp. So I need to know whats causing the temps to rise rapidly. My first suspision is the water pump....

Anyone got any ideas??

To add insult to injury the car went out of warranty last month....

Did u not get a small warranty with the car from the place you bought it from, thought you got it from trade as opposed to private?

from what i can remember about these warrantys is any garage can do the repair aslong as they give the warranty company a call as to what the problem is and also how much it will cost.some things are not covered though

Check out the fans. I had this problem last year and the car was using
a lot of coolant. The fans were making a lot of noise and working
intermittently. I think its the same problem Andymac has linked in his
sig. Once I got the fans replaced it all went back to normal. I did
also experience some loss of power before I got the fans changed.

Gave the car a thorough checkover myself. Checked all mods for codes with VAG COM and had an extended drive. This is my second 1.8T so I know my way round it pretty well.

Considering the problem has only occured this evening, well after a 250 mile drive it seems like its something thats happened recently and not an underlying problem.

Looks like I'll have to get it booked in with a dealer on Monday [:(]

Has this problem occured with the 1.8T ?

I'll check the fans tomorrow anyway.

Cheers matey.

Mate the dealer needs to have put a warranty on the car for at least 6 months. You should be able to get the car done in your local garage & they just need to get in touch with the warranty company 1st. If the warranty is with motor plan let me know!

Just so you know; my brother got a leon 110 tdi with a warranty (i.e.
not seat but aftermarket) a while back, similar symptoms (i know,
different engine) turned out to need new radiator, new expansion tank
and also a new maf. Maf was covered, other 2 were not. The warranty
companies consider these to be wear and tear and not liable, also not
liable for diagnostics. I would say the warranty will not cover you for
the diagnostics or the water pump, if thats what it is.

I've checked through the docs and found the warranty.... Its a 3 month jobbie with a limited claim of ?100.

I did see that beofre I bought the car but dismissed it as the car had low miles and FSH. I know, stupid thing to do and I certainly should have known better.

I just hope this isn't going to be expensive.

What crap luck Tabs, was it Motor Services Bath you bought the car
from? If so they are normally really good with aftersales - one of the
dealers that have a good reputation round here.

Get in touch with them and see what they can do but i'd say it was the
water pump if the temps were actually that high. Was the coolant
boiling in the expansion tank?

If not a dodgy temp sender could be guilty.

I think it occurs on both petrols and diesels.

No not them, its was small pokey place outside of Bath. I've always been on the ball with these kinds of things but I guess they catch us all out at some point.

Yup water was boiling up in the tank. It wasn't contaminated and there were no traces of exhaust gases either (which is a good thing). Must be the water pump - bit duff for a car with 16k on the clock if it is!

Need to get her booked into VW this week. Was really looking forward to going to the GTI Trackshow in her as well... Hopefully they'll have it sorted before then.

TABS.

I use to own a leon cupra engine code AUQ and had a problem like yours. What was happening was the temp gauge would go in to the red and the car would say STOP check coolant and it also sometimes went right down to cold even though the engine was normal temp. The offending item was the temp sender unit. By the way this didn't show on vag com.
