Engine Light on

Post by Tim B » Fri Oct 09, 2015 5:34 pm

I have a 2002 2.5 diesel with an intermittent running fault bringing on the EML light fault code is 1228 can anybody confirm this is a fault with the waste gate as I have been told the manual doesn't list the 4 digit codes on the later vans

Tim,you need to determine whether or not your vehicle has a waste gate fitted,the ex boost could and probably will be controlled by the turbo variable vane system if fitted.

Your old 2001 model should have the VV but you need to check it.

Good Luck

Hi there.

I had a longstanding problems with our 2002 Diesel Bongo with the dreaded going into limp mode and glow plug light flashing once engine was warm and sat in traffic. I cleared all the old fault codes and found the two fault codes being displayed were P0400 and P1228. Spent hours researching this trawling for answers through the forums, FB groups and it's also well detailed on the Wastegate Actuator factsheet in the members section. It's obvious people have spent hours on this, but nothing seems to give a permanent guaranteed long term fix. After much head scratching I discovered Mark at The Bongo Master in Leicestershire, really good, decent, honest bloke, who knows Bongos inside and out, he has great reviews from all his customers. Mark immediately knew what the problem was. It's a known issue with later Bongos, due to combination of a change of turbo design and poorer quality grade diesel in the UK. Mark charges £600 to retrofit an older turbo from an earlier model and changes the relevant ducting and piping to go with it. The van then ran as sweet as a nut, with no loss in performance at all. Just thought I'd share, as it could save somebody alot of time, money and hassle in the future.
