Sorry for just jumping straight into asking for help. I will start an introduction when my Alfa works
Ive just recently bought a 156 2.4 JTD, as a runabout to keep my E36 M3 GT2 in good condition.
The car was going fine until today when.
I changed the air filter. Attempted to change the Diesel Filter until i realised that i had in fact been given the wrong one, so replaced the old one, then changed the oil fiter and oil.
When i started up again. i had the red engine light (engine management light??) and a weird yellow water jar looking light beside the speedo.
The car now is not making full power, is only revving to 3100rpm, which is odd.
So plugged it into a friends diagnostic machine. and the following codes are being thrown up:
P0236 - Overboost Valve
P0638 - Flow Modif. Throttle
P0404 - EGR
P0101 - Air Flow Meter
is very odd that this is happening directly after me servicing the car.
Can anyone shed some light on the situation and where to start to try and get the car back to its former self??
