Its a really long story but basically my speedo rev counter and fuel guage arent working properly.. the revs are not what they should be lagging behind what engine is spinning at.. though idle shows correct and speedo the same says 50 but doing prob 70 and just gets worse faster you accelerate or go.. also My boost is limited to 0.5 bar.. should be 0.8 from memory.. its relatively slow to go up in boost as i remember it used to fly off the dash guage when you put the foot down going off the scale...
Now some history.. the boost was fine till i changed the spark plugs then i couldnt get the seal right on water chargecooler and ended up overclamping it and had to put another in.. Ive had the cooler off several times and no way it could be loosing boost.. ive fitted a new throttle body to intercooler connector and new turbo to intercooler hose with wide clamps.. its super tight..
I have changed vsv ... coolant temp sensor.. with no joy as well as checking all vacuum lines..
Checked ecu no codes.. though have seen you can put it in a sensitive diagnostic mode by crossing te2 instead of te1
My own personal View is its a bad earth.. though a bad speed sensor or crankshaft sensor would also make sense
im a big believer in going back on what has been done.. as i have seen cars operated on by muppets come out terminal.. lol..
the Timing belt was done so the crank sensor could be at fault??
the alternator was replaced.. so Maybe a wire to it causing problem??
Timing is correct. i set it in diagnostic mode 10 deg BTDC
Any help Appreciated before I go Mad Guys..
Anyone had this Fault with their car dash playing up and boost restricted.. A Faulty Relay or Something
Oh and yes i replaced the dash from another car i have.. and it had same faults.. the fuel guage could just be a coincidence..
