...but seriously.... depends if your car is mapped as to how obvious it is but if you have a boost gauge then soft limp will show around 0.5bar as its working on actuator pressure and the car will feel slow...
humm... 0.5bar is normally actuator pressure as a normal A3 should be around 0.7-0.8bar
Temp sensor shouldn't cause limp mode tbh but if the ECU thinks the engine hasn't warmed up yet it could be holding back boost until it does... does your temp gauge show 90degrees at all when warm?
yea the temp gauge will sit at 90 after it gets warm no problem at all. still only shows me 0.5 bar just been and checked. the only think i am thinking is the DV. i have a Baileys DV30 fitted.. but it was showing me 0.5 bar before i fitted that...so it shouldn't be an issue...
Checks hoses... maybe you have a boost or vacuum leak... vac leak would be my first choice... I had this when I had my car on the dyno shortly after finishing my BT conversion... the fuel pressure regulator pipe had split and this was where the boost gauge was tee'd from... the leak meant the boost gauge was under reading..
I dont know where to look for that... i'll see if i can see any obvious leaks.. i'll get a couple of pictures of my setup so maybe you can take a peek?
Basically check all the pipes coming off the inlet manifold, follow them around checking for splits etc... Also check the pipes coming off the turbo charge pipe... the ones going to the DV and the ones going to the N75...
Basically its a case of looking at all the pipes to see if they are still connected and are not split or damaged...
ok pipe was meant to be disconnected because it was for the old DV. I put my standard air box back in and the car feels sooo much quicker but im still only getting 0.5 bar :/ VAGCOM this evening might turn up some clues i guess but im sure none of the hoses are split. Could it be that the ECU needs to be reset to clear an old soft limp error?
ermmm... no such thing as a pipe that is meant to be disconnected.... A proper DV need a vacuum pipe, if yours is 'disconnected' then its prob leaking from that...
no its from where i disconnected the old DV to block it off so the new 1 can work. its disconnected properly. Im now getting 7.25 PSI which should be about right for the 20v Turbo 1.8 a3 AGU engine.
hummm... not sure I follow you... the DV30 is a recirc valve is it not? it should use the same connections as the previous DV.... there shouldn't be anything blocked off or disconnected...
Are you sure its fitted correctly? 1.8t's are sensitive to dodgy pipes and even dodgier DV's...
7.25 psi is still actuator pressure so I would say you still have an issue somewhere
