Hi there. First post on this forum...
My parents have a Mk5 Astra 1.8 (2007) Elegance Automatic. It over heated the other day and was towed to the local Vauxhall garage. What they have diagnosed is that the cooler pipe which carrys the Automatic transmission oil through the radiator has corroded and leaked oil into the water cooling system, gunging it all up, resulting in the over heat. They have flushed it all out, and replaced the pipe in question, and presented them with a bill for £250 for the trouble, as the car is slightly out of warranty.
This sounds like a ridiculous scenario (and that is coming from an Alfa owner!) I have a few questions....
1) does what they have told my parents sound feasible?
2) would the loss of oil from the transmission result in premature wear? Or maybe water ingress into the transmission???
3) Is this a common failure and something which they should go to Vauxhall UK about to get a goodwill payment for the work done? It sounds crazy that a pipe would corrode after only 3 years (and the car is looked after 100% by the Vauxhall dealer, serviced early etc etc etc).
I would really appreciate your thoughts and advice on this.
