Hello everyone, It's a firs time I'm actually writing on forum. I'm just looking for some advice if possible. Just bought a Roomster 1.4 tdi mk1 with 105.000 mi on clock. Driving from the garage was absolutely fine until I'm hit the motorway and tryed to see how it's runs. As soon as it reaches 85mph car went to limp mode with lack of power, low rpms and orange management light. I stopped on next serfice restart the engine and its back to normal just light on dash stays on but after a while it's off. After I get home I was driving round the town and about trying to faul come back. I was revving it, pulling hard, booting and alsorts but the car was driving well until I went to motorway and on speed 85 mph its happened again, I tryed again and a same thing. After connecting cheap OBD reader the code stored was P0234 turbocharger, engine boost condition - limit exceeded. Car drivers wery well with out any issues untill you go over 85mph. So is it a genuine fault with the car or its just some kind of speed limiter? Apologies for long topic, just trying to explain as much as possible. P. S. 85mph only been done for a quick test after I bought the car. And I glad I've done that and discovered this issue as garage gave me 1 months limited warranty Thank you in advance
