S 80 T 6 low compression at 75K miles

My wife's 2004 S-80 T6 (she likes the option to go when needed) was purchased new and has had all the required services by the dealer. Now the technician just brought it home saying that the compression in one cylinder is 80 while the other 5 are around 130. He suggested that the problem is valve guide wear, and that the solution is a valve job. He also said they have seen this in at least one other S-80. This car only has 75,000 miles. Has anyone else heard of this problem?

The question is have you noticed any drop in power or bad running / poor economy? If so what prompted him to do the test, its unusual to do it unless there is a problem.

Probably worth getting someone else to check it and pay them for the test, it shouldn't take long, many home mechanics should be able to do it too.

Valve guide wear is quite rare in most cars these days, but many things can affect it, such as driving style, fuel quality and general servicing. It could also have been a problem in the mfr of the engine.

You could try a claim against the sale of goods act, but it would be difficult to prove the fault or weakness was present at the time of sale (you have 6 years to claim). Certainly mentioning the Sale of Goods act will put the willies up the the branch that sold it to you. Volvo already got burnt with SoGA on the the throttle body problems. All retailers try to pretend it doesn't exist.
