As I'm on here
With all this weather we have all been having. The car has been playing up, a bit..
When driving in floods, loads of surface water and also just plain heavy rain, I lose all boost.
It only lasts just over a few minuets, if I'm doing 70 Mph it will not accelerate when it starts playing up and it is very sluggish going through the gears. It's 0-60 takes just over a minuet and when pulling out I have to make sure there is a very large gap to accelerate in, not ideal.
This problem did pop up once some time ago but I did't think to much of it as it shortly went away, it was also dry too.
C3driver52Did get some strange code that came up. Can't remember the P number but it came up with "Low turbo inlet pressure", very bizzare. I didn't know how the ecu can calculate a pressure value with just the MAF inline before the turbo. Upper deck pressure is referred to as "boost", which is where the MAP sensor comes in after the compressor section and intercooler. But I would guess the wording should be "Low turbo output pressure" ?? I gave the variable vane actuator link a pull and a push on the turbo. (Bit stiff and was hard to move, think it's got a stiff spring in the actuator). All has been fine till my starter motor packed up the other day, need to tap the solenoid every time to get it to start. I've just come to expect these minor sags with the age and mileage, coming up to 100k now. Can't complain over awesome MPG and road TAX.
I've got some pic's too.Hi Adam,
Yours being the 16v engine, you will see there is a MAP sensor as well as the MAF. The 8v doesn't have the MAP.Can't remember the P number but it came up with "Low turbo inlet pressure", very bizzare. I didn't know how the ecu can calculate a pressure value with just the MAF inline before the turbo.
This can explain how the ECU gets boost pressure and may prove useful at a later time.
