Morning all,

I took my car into the garage to have a coolant leak fixed. Coolant was apparently leaking into the V in between the cylinders (it’s a 3.0 TDi Audi A6 Allroad, 2015… details below).
No warning lights, no signs of any problems it was just that I noticed I was having to top up the coolant a bit more often than expected and it wasn’t leaking on to the drive.
That was apparently fixed by the garage and then when the garage took the car for a test drive the car had a turbo failure.
I agreed to have that fixed and a replacement turbo was sourced and fitted which seemed to take much longer than expected.
I phoned the garage yesterday morning for an update and was told that the garage had taken the car for another test drive post turbo fitting and 6 miles down the road the car had a catastrophic engine failure as the bearings had failed ! the car has been in the garage for over 5 weeks now !.
What are the chances of this happening in the normal course of things ? Turbos do fail of course and engines fail too, but all at the same time ! There were no signs of any problems at all with the car when I dropped it off and it drove perfectly.

Coincidence or human error ?

And what the heck do I do now ?

I’ve asked the garage to provide me with a thorough and detailed breakdown of everything they have done to the car to date and am waiting to hear back from them. I’ve also told them that I do not authorise them to do anything further on the car until we have resolved this.

I'd say all of the issues are linked.
The turbo oil feed and oil cooler all need to be disturbed to resolve the coolant leak and if these have not been replaced correctly it could result in turbo problems and potentially oil pressure issues that may affect the engine bearings.
It will be interesting to see what the garage say on the engine failure.

Yes very interested to hear the garage's explanation for how this occurred and their plan to resolve......

Guessing that the 'engine failure' was oil starvation to the crank? If so then i would imagine that these are connected. Low oil pressure or starvation will kill the turbo and crank within seconds.

Get the report from the garage, tell them when you have it that you believe poor workmanship has caused this series of failures and you want to know their offer on how to sort it before you go the legal route to recoup your loses.

Thank you so much everyone for your thoughts and suggestions on this. . Very much in line with my current thinking. Im hoping to have a report back from the garage early next week and I'll keep you informed !

I can’t see how it can be anything but human error. Good luck with everything, hope you can get it rectified.

Does a coolant leak fix really need a 'road test' in the first place?

I would have thought just running it for a few minutes would indicate whether the leak was sorted.

Car may need to be run up to temperature to get the cooling system moving and the thermostat opening so there's an argument a road test would be required because it may struggle to get warm enough just letting it idle outside the garage. I don't know this specific model of car though

I agree that this sounds connected. Proving it with a sensible financial outlay may be another matter.
I’d guess it comes down to how much store the garage place in their reputation locally. If they are a respected village mechanic with a long-standing reputation to uphold you may be lucky, but if it is a large chain or one of a thousand similar back street garages in a big city you may have a fight on your hands to get a resolution that is satisfactory.
Frustrating position to be in.

Yes I had a coolant leak and overheating job this morning, afterwards I idled it for 20mins but engine didn't get hot enough to check if the fan kicks in (105°) had to be sure there wasnt air trapped so had to take it for 10min drive. All was well.

I cannot recall owning a car that wouldn't get hot while idling, as there's no air flowing through the radiator. If the fans didn't kick in then the engine would boil over.
