i need some advice
we bought a vw t5 which had few problems with engine and gearbox
we decided to give it to a company to rebuild the engine and gearbox at a cost of £5300
in may 2017 he said it would be about 4 weeks
eventually we pick it up sept 2017
from the day i got it back it smoked ,the company said run it in
it never got better
then we got an oil leak from the rocker cover gasket which was to bad to drive back to company as its about 100 miles away
it cost me another £620
it kept smoking
i called the company again and he said it was our cheap turbo,
we had it taken off to find it was fine except the silicone sealant on the gasket which he denied doing,
eventually he convinced me enough to change the turbo, another £1000
and after this it still smoked
i decided to take it to a vw specialist else where
they stripped it to find quite a lot of things wrong
and its going to cost about £5000 for the engine build and gearbox as that has never performed correctly either.
They can provide photos and proof of poor workmanship I have sent a letter recorded asking for a refund on the advice from CAB , with no response, what should I do next?
