only had my V4 impreza one month and already replaced all the front engine sensors due to so called specialist advise only to still have the check engine light on.... So yesterday i removed the blanked off bonnet vent plate to let more engine heat out then drove car for 60 miles and the engine light hasnt come on once since! I wonder how many others have parted with their cash because of bad advice from certain garages that make alot of money from performance car owners!

 

As someone of many years experience of Subaru Imprezas, I'd remain open minded to the possibilities of red herrings

 

i wonder how quick you will put the blanking plate back on when you see what the rain does.

 

lol sorted a nice cover for battery area.

 

I have now taken my whole bonnet off, car runs like a dream and no fault codes either.

Thanks, you must have saved me a fortune

 

Vent removal has removed a CEL - seriously? If that is true then your car has bigger issues!

 

true there must be a probelm somewhere.. Maybe a dodgy wire made worst when heated up but drove another 30 miles with no probs so happy for time being.

 

Did you have the CEL investigated to see what code it was throwing up ?

 

Threads get more strange by the day...

 

yes.. Replaced crank.. Cam sensor as codes were there then had ecu reset.. Last week had it checked again and then flashing water temp.. Knock.. Mass air fow sensors... Ive since reset it again since taking vent plate off and nothing! So weird!

 

No, you're right. I've done this to my car and it runs perfectly!

 

 

**** it, I might just sell my Subaru and get a horse. They don't even have an ECU.

 

They do though, see picture below, quite difficult to replace though when it goes wrong but at least you can recycle your transportation into glue
