Check engine light?

Check engine light?
Just done the fault code check but I'm still confused 1st sequence is slow, slow then quick, quick then 2nd sequence is slow, slow, quick, quick, quick then 3rd sequence is slow, slow, slow, slow, slow, quick, quick, quick. Then it goes back to the first sequence. Now what the frig does all that mean or Is my classic ****ed? HELP please people.
I have posted this in the main section but hoping for more info as to what could be wrong from my fellow welsh people.

How to read the flashing Check Engine Light
A steady even spaced flash = no stored faults.
A slow flash = x10
A fast flash =x1
So for example if you see 2 slow flashes and 6 fast flashes your fault code is '26', the function can show you multiple codes too so it is handy to have a notepad and pen handy to write the codes down as you read them, if there are multiple codes they will be shown in a looped sequence with a pause between codes ie (2 slow - 6 fast - PAUSE - 3 slow 4 fast - PAUSE) once the last code in the sequence has been flashed the sequence repeats so dont panic if you did not catch the code the first time round. It is worth watching the sequence for a few loops to ensure you have taken down the correct codes.

By the sounds of it the motor has more than one fault code, I ain't no genius but I'm sure slow flashes are the tens numbers ie 10 20 ect then then the fast are the individual numbers ie 1 2 3 ect giving you the fault code ..slow , slow ,fast being fault 21 , if that makes sense..please correct me if I'm wrong . Just write the codes down and then check on the code list what faults you have ..hope helps

Well 53 can cover all these things...
53 Antenna
53 Anti-Quick Operation Mode
53 Communication Error (Time Over)
53 EGI Control Module EEPROM
53 IMM Circuit Failure (Except Antenna Circuit)
53 IMM Control Module EEPROM
53 Key Communication Failure
53 Reference Code Incompatibility
53 Use of Unregistered Key
Which could mean a factory fitted immobiliser? Are you using a new key?

I don't think you would suddenly get all those sensor failures - I'd get it into a specialist for diagnosis before you start throwing parts at the car.
You will probably find it all relates to one issue rather than a whole series of failures.

Not so guys, You can have more than one failure at the same time.
What happens is that the sensor has failed or very nearly fails but doesn't show when another sensor fails it picks up on that one also.
Had the same on my old UK car, MAF and Knock, nothing showed until the MAF went.
Seems quite common for the MAF and Knock to show at the same time, if you replace the MAF and then reset ECU, the knock sensor stills shows as being faulty, change that and all is good

I understand what you are saying Danny but it would be better to spend £X on diagnosis and get the cause identified, rather than spend £Y on parts and potentially they don't cure the underlying problem.
Especially as the MAF is not exactly the cheapest of sensors either.

Any ideas on where the cheapest place to buy a new knock and maf sensor from for a uk turbo? I started the car and the check engine light came on then after around 5 minutes it went off, but I unplugged the maf sensor while the car was running and upon doing this the car cut out. Does this mean that the maf is ok or not really as it is one of the faults showing?

Yes (and no). It should cut out but not always but 99.9 % of the time it should

OE Bosch sensor but you could take it off give it a bit of emery cloth on both sides, check for cracking or damage and try again. They doo **** up as they are below the IC airflow.

Here for the parts: http://www.importcarparts.co.uk/ Not worth fitting cheap sensors, stick to genuine Subaru parts for those.
Unplugging the MAF isn't a reliable test if it works or not TBH. Not sure how to test it, but i'm sure someone will be along with an answer shortly.
