No, I gave the car back, I did message them to see if they found the problem but they never got back to me

As in the coolant itself and not the air/gas in the expansion tank? No, the garage hasn't suggested anything, they had it for 2 weeks trying to find the fault and took a stab in the dark that the charge cooler was to blame. They've given me the option of handing it back for a refund or to leave it with them until fixed, after their first attempt took so long and them being 165 miles away I've opted for handing it back. I'll keep in touch with them and let you know what the fault is/was Thanks you for you input and suggestions, much appreciated

The problem with checking the tank for exhaust gases is that when the symptoms are showing the coolant is very high in the tank, I'm assuming because of gas in the system. http://tinypic.com/r/259x5z8/9 Before the car went back to the garage I had torque logging the coolant temps a few times and not once did it go over 89℃ whilst driving at a fair pace though the Charge Air Coolant Temperature did see 135℃. Any idea what the target temperature is? If driven fairly slow it could take a few tanks of fuel for the coolant light to come on The coolant is the red stuff and is fairly clean

Hey all, Car is a 2013 mk3 Octavia 2.0 150PS CKFC ea288 Manual It's loosing coolant through the coolant expansion tank relief only when driven enthusiastically/up long steep gradients. It's had a new gates cam belt and water pump, expansion tank and cap and a new charge cooler. It's had a sniff test on the coolant which showed nothing (I know this isn't conclusive). It's holding coolant pressure whilst cold but not whilst hot. The egr cooler isn't showing signs of coolant residue inside. The old charge cooler was tested but not obviously faulty. I've recently had it back from the garage I bought it off after they thought they had found the fault, the charge cooler. After 40 odd miles I was parked up and waiting for a dpf Regen to finish, revs were at a steady 1k and it was ticking over for about 5-10 minutes when I noticed the smell of coolant, a nice big wet patch under the car. I popped the bonnet and the coolant tank was way above maximum with coolant briefly coming from the relief hole. I opened this after it stopped and there was a lot of air coming from the tank outlet (after gushing coolant everywhere) A Volkswagen specialist has told me he hasn't come across a head gasket failure on these engines yet. Am I right to think that after a new charge cooler that just leaves a head related leak or the egr cooler to be at fault? Any helpful thoughts are appreciated

Did you get to the bottom of this problem? I have a similar problem on my mk3 2.0 tdi ckfc.

I found this really helpful non clearing up what tools are needed exactly! seainsvs4740.pdf

OK, thanks!

Thanks Octyal! Does anyone have any info on the timing kit tool differences?

So I've decided to change the timing belt myself on my 2004 Octavia I've google the **** out of it and done the searches on here and it is to my understanding that the procedure is exactly the same on the 1.9 ALH and ASV engines I'm looking to buy the locking kit online but the kits that are available for the ALH and a load of other 1.9 TDI engines don't list the ASV as in the compatible with list. The kits that do list the ASV are £100+ Whilst I'm here.. The engine is on 140,000 miles, is there anything else worth doing whilst it's in bits apart from the water pump? Thanks, Jake

I've had my Octavia a few thousand miles now so thought it's time to join a forum! Mainly to pick your brains lol I'm from Bridged, South Wales
