Welcome to the forum, Josh. I'm going to assume it's a diesel, don't often hear about limp modes in the petrol versions.
Could be one of several things. Some models have a faulty EGR unit (might just be the software, not sure on that) and dealers have been replacing it as part of a recall.
It might also be the SCV - Suction Control Valve - it's part of the fuel pump. If it is, you can repeat the problem by getting the car to around 80km/h and planting your foot to the floor - the car should go limp. If it does, don't go getting a new SCV - have yours removed and cleaned, it's most likely just dirty. Then replace your fuel filter and re-think where you buy your diesel from - high turnover outlets (eg popular truck ports) or brand new servos are the best source.
Otherwise there are a number of things that could cause it, and sometimes it's just an electrical gremlin. The most common electrical gremlin is in the earth to the engine and to the ECU - remove, clean, reinstall then spray that blue shit over it to reduce corrosion.
Hey Mate, If your new exhaust has deleted the dpf without removing the sensors from the ecu then your always going to run into trouble..hi guys ..iv had a full 3 inch exhaust fitted to my stx550 ...now i have no power ..
The STX550 did not have a DPF fitted to them (empty shell only) so there should be no problem there.hey mate ..yea it had a dpf that had nothing plugged into it (already been sorted i was told) ...and yes a strait through system now ..will go get the codes looked at tomorrow ...it went good after i reset but only for 1 minute then back into limp and engine light on
thanks for that lads no light comes on in dash just revs to 3000 and wont go any further no power flick the key real quick on and off and away she goes till u come to lights or junction same again doesnt do it when cold
