I had the head gasket replaced yesterday following the advice that this was the cause of the 'STOP CHECK COOLANT' warning light which kept appearing.
The oil was changed, and the whole job cost nearly £1,000.
However I am disappointed that on the way back from the garage, the warning light appeared again.
I drove back to the garage and he said that it might be because one of the hoses is constricted. When I release the expansion tank lid, the air is released and the coolant returns to the 'high' level, which is better than what was happening before, when I had to keep topping it up.
The mechanic says that I should return to him with the car if the problem continues. Anyone got any advice, please? I seem to be stuck with this problem and do not feel confident to drive long distance. The engine temperature never goes above normal.

I put new water pump and timong belt on my Tiguan (2.0Tdi Diese) it took a few journeys to ge the coolant sorted. Check to see if your car has a coolant bleed screw.

Any good garage would have tested the vehicle thoroughly prior to returning it to the customer.
I hate these type of scenarios where you get someone to do the job, pay them and find there is still an issue.
Had this type of issue with Porsche garages and it is just due to people cutting corners by not checking the work that has been done.
Hope you get it sorted soon and can start enjoying the car again 👍

Thank you iangaryprice. The garage said my water pump was OK, and so was the timing belt, so he didn't change it. I'll mention the bleed screw to the mechanic when I see him. All best.

Thank you Scorpion. This garage was recommended to me by a bloke who has his 1958 Jowett serviced by them. In fact they stripped the engine down and rebuilt it for him so I have a certain amount of trust in them. I'll be going for a run in it today and watching the temperature gauge. I think that it's working OK. All best, and I'm so glad to have discovered this forum.

I returned to the garage having had my head gasket replaced, and told him that the 'Stop Coolant' light was flashing again.
He put a whole bottle of Steel Seal into the expansion vessel and the car ran for 40 miles or so with no problem. The longest it has ever gone during this problem without a warning coming up. However, today, the Stop Coolant warning came on again, but the coolant level wasn't so low. I just happened to be passing the garage that did all the work so I popped in. The bloke topped up the coolant and said I might need another bottle of Steel Seal 'in a few weeks'. Apparently it takes time for the heat to solidify at any any crack. The problem could be a tiny split in a hose which is allowing exhaust fumes to enter and push the coolant level down. He poked a tube into the expansion vessel and the liquid inside turned green, and not blue, which it should have done. He is also blaming the EGR valve, which I don't think is a genuine VW part.

I would be questioning if the head gasket was the issue in the first place?
I would then try another garage as from my experience the garage is just guessing what the issue is and then doing a cheap fix using Steel Seal which is not the way to address the issue for the long term.
The problem needs to be diagnosed and fixed using a replacement new part.
Look for a VW independent garage in your area and get them to check the car.

Thank you, Scorpion. The latest news in the saga, which is getting longer than War and Peace, is that I have been putting in a litre of coolant a day. I took it to Volkswagen main dealer, who I have been avoid because the labour is £138 per hour, plus diagnostic tests, where a helpful technician told me that he could see water running down the engine on the driver's side. This was after I noticed a pool of fluid beneath the car at the shopping centre in Barnstaple, Devon.He suggested I take the car back to the garage where I had the new head gasket fitted. The VW man told me they should have fitted a new water pump and cam belt as well. So it was back to the original garage who now have it overnight and I had to get the bus home. They have agreed to do all the work and cure this coolant problem for once and for all, and i will be in heaven.

I am sorry to hear that this saga is still going on.
At least once this other work is done the car should be ok.
I would also look for another garage for future work as this one is clearly not capable of doing the repairs correct first time.
There will be a good garage near you it is just a matter of asking around.

Funny you mention that shop Scorpion, they were the one shop I found that would assist on getting GTD parts crated and shipped to a Canadian Tuner I was working with to get my TDI into full euro mode. Sadly the engine parts were no issue but the bumpers were held in customs for not meeting NA safety standards. (no side markers) lol great bunch of chaps there.

Very pleased to report that the garage which fitted the head gasket has now replaced the cambelt and the water pump. With the extra antifreeze and consumables, the bill came to £232, because I wasn't charged for labour. I think that he did it because he realised he should have fitted those items in the first place when fitting a new head gasket, and I do wonder if it needed doing at all. Nevertheless, it's done now, and I drove 40 miles with no problem. I even checked the coolant level three times whilst out and about, and it remained at the max level, so very pleased that a problem that has been dogging me since November 2020 is finally resolved. Best wishes.

Thanks, Scorpion. I meant to say that he bypassed the cooler which he didn't think was necessary and would cost £700 to repair. All best. You were part of the solution.
