EPC Fault - Check Sum Error 0601

[James_R]

What is the rough oh&p percentage for the Revo maps, if you're allowed to release that sort of info...

You're asking a monkey organ grinder questions there mate

 

[Joshkcupra]

Haha, fair enough! I think I have discovered why I've got an epc fault, the PCV is shagged...
Would this throw up an epc light? My boost has dropped and the revs are jumping on idle

 

[James_R]

No but it would log a detected air leak fault on the ecu

 

[Joshkcupra]

So what light would it light up on the dash, if any?

 

[James_R]

The engine light. But it would be logged as a priority 2 fault so would take some time before it appears.

 

[Joshkcupra]

See my engine light is on alongside the epc....

See my engine light is on alongside the epc....

Which takes you back to your fault codes which is a defective ECU or more likely corrupted software requiring a re-flash; have a look here in reference to BWA engines: http://wiki.ross-tech.com/wiki/index.php/16985/P0601/001537

When I had the same codes I had the EML and EPC lights on.

 

[Joshkcupra]

My PCV Valve is knackered, I pulled out the dipstick whilst the engine was running today and the whole engine choked, I think that's why the engine light is on

 

[Paulki]

It sounds like you have 2 separate faults, the PCV which doesn't relate to the fault codes in your first post, and the ECU software issue which is what those error codes indicate and would cause the EML and EPC lights to come on.

Where are u based mate? Just had same issue and got it fixed a lot cheaper than the £1200 quote from seat! Less than 10% cheaper in fact!

 

[Joshkcupra]

I'm from Gravesed in kent

 

[Dodson84]

Ah this place is in north east near me!

 

[Joshkcupra]

So what did they do to fix it?
