It is in Swedish, but i guess, hope, that the codes are all, but universal.

DTC 2135 - Description in Swedish (Gaspedalläge - intermittent)

DTC 2111 - Description in Swedish (Gasspjäll fjäder - intermittent)

DTC 2110 - Description in Swedish (Gasspjäll fjäder - intermittent)

Two weeks ago, I have my full service in Volvo itself, and they told me that it is time to change the ETM. After I have seen a lot of forums, people said that even after changing the ETM, they still see the 'reduced engine performance' notice, which I am seeing it now. And Volvo ask me to pay about $630 for it. Well, I wonder if it worth it, or if there is any other explanation to these problems. In addition, I wonder ETM on V50 '06 volvo cars are still under warranty for 10 years or under 200,000 miles.

Thanks,
