Opel Combo 2010

Iv had this van 8 years and its being great but I needed a 3 seater. It's a great lil run around its unbelievable on diesel so cheep to run. Engine and gearbox is 100%. It has DOE till September Now its not perfect it was a painters van for most of its life it has a light on the dash for cooling fan I changed the relay but it still stayed on. It goes into limp mode when you go above 3000 RPM. It's the boost actuator is stuck its sat up since January coz I didn't want to sell it. It mite be possible to free up. The wipers work good but they stop wherever they want at times. It had a new alternator replaced last year and water pump tensioner and belt. It needs a good clean .
