Hi all .. I have the dreaded codes that seem to be like some kind of epidemic. The classic P2036-001 (P0410), and really need some help with this one.
The codes are saying "Secondary Air Injection Too Gearing" .. I have done just about everything I can find on this fault .. checked 1 way valve (no issue), replaced Vacuum Valve, Checked all hoses (no faults), replaced front Lambda etc etc ..
When I start the car from cold .. it hunts all over the place on occasion (revs go anywhere between 600 to 1200 rpm and sounds like its on 3 cylinders almost for about 10 secs then stabilizes. The EML stays out when cold, but when the car is warm, it throws the codes randomly.
I have searched and searched on this issue and can't find anything on this particular issue. Based on logic .. I think the key is "Too Gearing" .. If a valve was blocked or vacuum issue .. then "Too Gearing" wouldn't come into the equation ??
This thought leads me to possibly one of 2 units .. either the air flap on the Supercharger or the one on the inlet manifold, but the question is which one ? The car is running fine apart from this and seems to drive like it should without any other codes coming up on the ME system. I have been on this issue now for around 4 months off and on and cant trust the car to even go 20 miles without this code coming up. There is nothing more frustrating than throwing money at a car that has to stay off the road cos it can't be trusted .. Grrr
Can anyone help or had this issue before ? .. cos this is now doing my head in !!
Many thanks in advance for any input
