Posts: 3 Thanks: 0 Trader Rating: 0 ![]() | HELP!! T-jet limp mode problems :( Hey guys really need some help here.. Ill start from the beginning, got myself a grande punto t-jet 57 plate.. it was standard when I purchased it and was running fine with no problems, I put the abarth turbo on it and had it remapped around a month later, all was good until about 4 days later when I started to notice performance was going down hill daily, a week later I found a boost leak (big split that was getting bigger) had that fixed and it was running better than ever for a few days. I was out on a drive and accelerated quite heavily (as you do ![]() ![]() Thanks

Posts: 2,695 Thanks: 372 Trader Rating: 0 ![]() | Re: HELP!! T-jet limp mode problems :( Hi Jon and welcome on board, originally the 1.4 Tjet has a wastegated turbo, I'm pretty sure the Abarth uses the same technique to "regulate" the turbo boost. Seems like you're exceeding the Limp mode threshold when down-footing the car. How did you get the error code ? Some cheap readers have ironic or even incorrect messages; best way would be to compare the desired vs delivered boost pressure together with the turbo (wastegate) actuator signal ; From there we should be able to narrow-down the possibilities. Definitely need to invest in a MES + eOBD interface... Regards, Bernie If someone here helped You fix or understand your issue, hit the thanks icon in the lower right corner, it's free and make us happy !!

Posts: 7 Thanks: 0 Trader Rating: 0 ![]() | Had a bad week, went to set off and the car died, turns out its been the woodroof key ripping itself apart putting it in limp mode, so put it in the garage and had the bottom pully replaced, had it all timed up and it had a missfire, so I had it stripped down and all the valves checked which turned out to be fine, so built it back up new headgasket and bolts, so replaced the full timing belt kit and waterpump, plugs, coilpacks, every sensor I could find on the engine, still the same, its gradually got worse as ive been trying to start it to read codes and things, ive not driven it at all and now it turns over but will not start at all, had a auto electrician plug it in and hes diagnosed it as the ECU he said its broken down and now its given up, so ive got a full ecu, engine ecu, clocks, lockset, transponder and key on its way so maybe ill get somewhere then!
