Broken already! VW T5 engine loss of power 350 miles from home ! 

Hi. You need to get it plugged in to diagnostic really. Could be a boost issue.

@@DarrenRC76 cheers. On a service he did in a garage it came back various diagnostic teuble codes. It's been way for a long time . Not sure if something is blocked. Thanks for you quick reply 👍

Could be one of a couple of things. Boost related. Things to check, I would start with the following. Check what a scan of the ecu says. If it’s low boost pressure it could be a leak from somewhere. The most common are the vacuum lines, boost pipes and a split intercooler. Really carefully check all the boost pipes, the joints are prone to either coming apart or leaking, they must be seated correctly or they’ll leak which will give poor performance and economy. If it’s overboost on the ecu scan it could be the turbo. Turbo issues are common but generally they give overboost as the vanes stick and can’t change position.

@@dcdtransporters thanks for that. Can't believe what just happened. So the guy who I got the van off knew there was warning codes to the ECU-turbo and didn't tell me. And it was constantly in limp mode. I bought it anyway because I don't know anything about machanics. A post popped up about the turbo boot control sensor and how to give it an air test and I spotted a really small pipe not connected so I popped it back in and boom. Turbo back on and no warning lights and limp mode. Two garages I've been to and not been able to fix. Thought I was going to have to by a turbo 👍
